This is what makes the engines non-circular. Ante este movimiento de la competencia, Boeing decidió evolucionar su modelo 737 para dotarlo de motores que le permitieran llegar a nivel de consumo similares al A320. The 737's controls are very safe. A "thrust reverser" is a part of the engine of a plane. It has curved walls. [22] This type of 737-200 became known as the 737-200 Advanced. It succeeds the Boeing 737 Next Generation (NG). The 737-900 is the longest 737. The 6,000th 737 was delivered to Norwegian Air Shuttle in April 2009. [84], In July 2008, Delta Air Lines got the first -700 that had Messier-Bugatti's carbon brakes.[64]. These enhanced short runway versions could increase pay or fuel loads when operating on runways under 5,000 feet (1,500 m). Boeing ha coinvolto le compagnie aeree nello sviluppo del 737 NG. [11] To expedite development, Boeing used 60% of the structure and systems of the existing 727, the most notable being the fuselage, which differs in length only. Boeing 737 je úzkotrupé dvoumotorové proudové dopravní letadlo pro krátké a střední vzdálenosti. It was equipped with CFM56-7 high pressure ratio engines, a glass cockpit, and upgraded interior configurations. [14] Boeing cancelled the Boeing Supersonic Transport and started making less Boeing 747s. Sales were low in the early 1970s[26] and, after a peak of 114 deliveries in 1969, only 22 737s were shipped in 1972 with 19 in backlog. 738: 186. Il loro messaggio è stato molto chiaro: tecnologie avanzate che sposino semplicità, affidabilità e bassi costi, non tecnologie solo per il gusto delle novità. It has an auxiliary fuel system, giving it a range of up to 4,725 nautical miles (8,751 km), and a Head-up display. Many countries use the 737 as a military plane. [121] This has been raised as a safety issue because of the impracticality of duplicating such a mechanical cable-based system in the way that an electrical or electronic system can be. In two total loss accidents, United Airlines Flight 585 (a -200 series) and USAir Flight 427, (a -300), the pilots lost control of the aircraft following a sudden and unexpected deflection of the rudder, killing everyone aboard, a total of 157 people. Scienza e tecnica ... Consumo di carburante a velocità di crociera: 13.500 L/h ops confuso con il 747 ha … [12], The proposed wing airfoil sections were based on those of the 707 and 727, but somewhat thicker; altering these sections near the nacelles achieved a substantial drag reduction at high Mach numbers. [1][73], The 737-400F was a 737-400 changed into a cargo plane. It was the last NG to be launched (it was launched in December 1997). The initial concept featured podded engines on the aft fuselage, a T-tail as with the 727, and five-abreast seating. At the time, Boeing was far behind its competitors; rival aircraft in service SE 210 Caravelle and in development, the BAC One-Eleven (BAC-111), Douglas DC-9, and Fokker F28 were already into flight certification. A total of 30 737-100s were ordered by Lufthansa 22, Malaysia–Singapore Airlines (MSA) five and Avianca two aircraft with the final commercial delivery took place on October 31, 1969 to MSA. The 737-400 was launched in 1985 to fill the gap between the 737-300 and the 757-200. [31] The 737-400's first flight was on February 19, 1988. A fuel dump system is a system which gets rid of any unneeded fuel if the aircraft needs to make an emergency landing while it still has a lot of fuel on board. The NMA project was set aside in January 2020, as Boeing focused on returning the 737 MAX to service and announced that it would be taking a new approach to future projects.[109]. Boeing 737-300 = 3.000 kgs/h. The very first 737 model was the 737-100. [54] It and two production aircraft flew a nine-month-long certification program. If it has to land at an unsafe weight, the plane needs to be looked at for damage. [7], Boeing was looking at designs for aircraft which flew short distances. Giving a length of 36.45m (119ft 7in). Aircraft which were made before the improvement could have it installed. [36] Until retiring its -200 fleet in 2007, Alaska Airlines used this option for some of its combi aircraft rural operations to serve many unimproved runways in Alaska. [18][20] The first flight it made for United Airlines was on April 28, 1968. The 737-900ER (Extended Range) is the newest and largest variant of the 737NG generation. Història. The fuselage cross section and nose is derived from that of the Boeing 707 and Boeing 727. They have been made since 1996 by Boeing Commercial Airplanes.All 737s are twin-engined, narrow-body airliners. The 737-600, 737-700 and 737-800 planes were planned. The thrust reverser doors were set 35 degrees away from the vertical to allow the exhaust to be deflected inboard and over the wings and outboard and under the wings. It was also made to be a rival to the Airbus A321. [116] On a 737-800 this gives a 0.5% improvement in fuel efficiency. La capacidad está calculada en galones, pero al planear el consumo de combustible el cálculo se hace en libras. [100], From Simple English Wikipedia, the free encyclopedia, "German Airline Buys 21 Boeing Short-Range Jets. This was named the Boeing Y1 by people who worked at Boeing. The "Next Generation" models are the 737-600, 737-700/-700ER, 737-800, and 737-900/-900ER. [home.deds.nl/~hink07/Report.pdf "Analysis Landing Gear 737-500. [17] In May 1971, after the 135th aircraft was built, all of these improvements, as well as better engines and more fuel, were put into the 737-200. [1][73], In the 1990s, Boeing realised that the Airbus A320 family was a serious threat. The 737-500 is around the same length of the 737-200. Após passar por todas as avaliações do cliente, as aeronaves são encaminhadas para Seattle, onde fica o centro de entregas da Boeing. [13], The first 737s were made near Boeing Field (now officially called King County International Airport) because the factory in Renton was too busy building the 707 and 727. This engine burned much less fuel and was much less noisy. Eyebrow windows were used on the Boeing 707. ", "Why Ted's demise is a boost for business travelers", "Next-Generation 737 Production Winglets", "Boeing Delivers 737-400s to CSA Czech Airlines", "The end of an era: Alaska retires unique cargo-passenger 'combi' planes", "ANA Sets Boeing 737-500 Retirement Date", "First Boeing 737-700 Goes to Southwest Airlines", "U.S. [21] Lufthansa received its first aircraft on December 28, 1967 and on February 10, 1968, became the first non-American airline to launch a new Boeing aircraft. On July 23, 2013, Boeing completed the firm configuration for the 737 MAX 8. The main cabin (where the passengers sit) was also made better. The number of passengers it can carry ranges from 85 to 215. The 737 MAX family is designed to offer the greatest flexibility, reliability and efficiency in the single-aisle market. The gearbox makes the engine look a bit like a triangle. [18] Lufthansa got its first 737 on December 28, 1967. [17] Airlines liked the 737-200 much more than the 737-100. The wing was changed again. After the introduction of the Next Generation series, Boeing introduced the Boeing Business Jet (BBJ) series. [16] Detailed design work continued on both variants simultaneously. WestJet was to launch the 737-600 with winglets, but dropped them in 2006. [17] It was the only large airline which bought the 737-100. Boeing and CFM fixed this problem by putting the engines slightly ahead of the wings instead of putting them right underneath. It is offered in four main variants, typically offering 138 to 230 seats and a range of 3,215 to 3,825 nmi (5,954 to 7,084 km). The -700 was based on the 737-300. Since the engine is close to the ground, it is possible that they can be damaged by things lying on the ground. They also help make less noise on takeoff. The 737 MAX 7, MAX 8 (including the denser, 200-seat MAX 200), and MAX 9 replace the 737-700, -800, and -900 respectively. Deliveries are supposed to start in 2017. The 737-900 was launched in 1997. O consumo de combustível também é fator primordial para as companhias aéreas. [35] [42] In late 1993, after engineering trade studies and discussions with major customers, Boeing proceeded to launch the third derivative of the Boeing 737, the 737 Next Generation (NG) -600/700/800/900 series. Takeoff payloads were increased by up to 2,000 lbs on the 737-800 and 737-900ER and up to 400 lbs on the 737-600 and 737-700. LAM introduz Boeing 737-700NG na sua frota O plano de renovação, modernização e expansão da frota da LAM entra na sua segunda fase este ano com a aquisição de uma aeronave Boeing 737 -700NG. [181]:13[182]:ix As a result of the NTSB's findings, the Federal Aviation Administration ordered that the rudder servo valves be replaced on all 737s and mandated new training protocols for pilots to handle an unexpected movement of control surfaces. The P-8 can be operated in the anti-submarine warfare (ASW), anti-surface warfare (ASUW), and shipping interdiction roles. These models go from 102 ft (31.09 m) to 138 ft (42.06 m) in length. [31] Boeing also provided the 737-200C (Combi), which allowed for conversion between passenger and cargo use and the 737-200QC (Quick Change), which facilitated a rapid conversion between roles. Two T-43s were later converted to CT-43As, similar to the CT-40A Clipper below, in the early 1990s and transferred to Air Mobility Command and United States Air Forces in Europe, respectively, as executive transports. Since the wings were made bigger, 30% more fuel could fit in the plane. Existem quatro modelos básicos de Boeing 747, denominados 747-100, 747-200, 747-300 e 747-400. It can fly for around 3200 nm. [146], The Boeing 737 Classic, Next Generation and MAX series have faced significant competition from the Airbus A320 family first introduced in 1988. These are made by Messier-Bugatti. If the hydraulics or both engines fail, servo tabs will be automatically used. Most 737 cockpits have "eyebrow windows". The newest 737 variants, the 737 MAX series, feature LEAP-1B engines from CFMI with a 68 inches (1.73 m) fan diameter. The wingspan was also made bigger. Norwegian Air Shuttle Boeing 737 MAX 8 PPC: 220136MAX € 13.90 6 in stock 1:400. It looked similar to the cabin of a Boeing 757. The flight deck was given modern electronics (called avionics). The Airbus A320 family has sold more planes than the 737NG over the past ten years. However, 149 can fit in if the aircraft only has an economy class. The Boeing C-40 Clipper is a military version of the 737-700C NG. The prototype 737-800 was finished on June 30, 1997 and first flew on July 31, 1997. It can fly for 5,510 nautical miles (10,205 kilometers). These are Original, Classic and Next Generation. These were later divided into what has become known as the four generations of the Boeing 737 family: The launch decision for the $150 million development was made by the board on February 1, 1965. [129] Continental Airlines,[131][132] Alaska Airlines,[133] Malaysia Airlines,[134] and TUIFly have also received Sky Interior-equipped 737s. [59][60], Engines on the 737 Classic series (300, 400, 500) and Next Generation series (600, 700, 800, 900) are not shaped like a circle like most planes. [16] On December 15, 1967 the Federal Aviation Administration said that the -100 was allowed to fly with passengers. [62][63], As of July 2008[update] the 737 has carbon brakes. [175], As of February 2020[update], there has been a total of 481 aviation accidents and incidents involving all 737 aircraft,[176] including 214 hull losses resulting in a total of 5,565 fatalities. [163], In 2016, there were 6,512 737 airliners in service (5,567 737NGs plus 945 737-200s and 737 Classics), more than the 6,510 A320 family. Worldwide, the first airline to resume passenger service was Brazilian low-cost Gol, on December 9, 2020. [36] The -600, -700, -800, and -900 models are all part of the 737 Next Generation program. [59] The 737-400 was replaced by the 737-800 of the Next Generation series. Over 4,500 are still being used by airlines. [49] Boeing wanted to increase capacity and range, incorporating improvements to upgrade the aircraft to modern specifications, while also retaining commonality with previous 737 variants. [114] The eyebrow windows were sometimes removed and plugged, usually during maintenance overhauls, and can be distinguished by the metal plug which differs from the smooth metal in later aircraft that were not originally fitted with the windows. [40] Produced from 1984 to 2000, a total of 1,988 Classic series were delivered.[41]. [52], On July 20, 2011, Boeing said that they were working on a new 737 version, which would have the CFM International LEAP engine. Many different changes were made. The BBJ3 has 1,120 square feet (104 m2) of floor space, 35% more interior space, and 89% more luggage space than the BBJ2. The fuselage length of the -500 is 1 ft 7 in (48 cm) longer than the 737-200, accommodating up to 140[57] passengers. The 737-700, the first variant of the Next-Generation, was launched in November 1993 with an order of 63 aircraft. [156] Users with 737s include: Boeing delivered the 5,000th 737 to Southwest Airlines on February 13, 2006, the 6,000th 737 to Norwegian Air Shuttle in April 2009,[157] the 8,000th 737 to United Airlines on April 16, 2014. It could carry 10 pallets of cargo. Envisioned in 1964, the initial 737-100 made its first flight in April 1967 and entered service in February 1968 with Lufthansa. El regulador europeo de seguridad aérea espera autorizar vuelos del Boeing 737 Max en enero, ha dicho este sábado Patrick Ky, director ejecutivo de la EASA. The tyres can be seen easily when a 737 is taking off or is flying low-down. It entered service in 1968. Kone on niin yleinen, että voidaan sanoa niitä olevan joka hetki vähintään 1 250 kappaletta ilmassa. ", Board Approves Re-Engined 737&channel=comm "Boeing Board Approves Re-Engined 737. Por estar equipado com Winglets há economia adicional de combustível. ", "Continental Airlines Is First North American Carrier to Fly With Boeing's New Sky Interior. The US Air Force saved the program by ordering T-43s, which were modified Boeing 737-200s. Australia is the first customer (as Project Wedgetail), followed by Turkey and South Korea. The 737's main landing gear (wheels) go into holes at the bottom of the plane. [87] Entry into service with launch operator Southwest Airlines was expected in January 2019' but the airline deferred these orders until 2023–2024.

"Hub caps" complete the aerodynamic profile of the wheels. The newest cabin design is called the Sky Interior. These are divided into four generations but all are based on the same basic design. Winglets can be fitted to 737s which do not have them already installed. Alaska Airlines was the first to convert one of their 400s from regular service to an aircraft with the ability to handle 10 pallets. [1], The 737-700 was added to the Next Generation planes when Southwest Airlines ordered one in November 1993. [179], During the 1990s, a series of rudder issues on series -200 and -300 aircraft resulted in multiple incidents. [71] The -200 Advanced has many improvements. É o único avião narrowbody (corredor único) da Boeing em produção, nas versões -700, -800 e -900. Following the merger between Boeing with McDonnell Douglas in 1997, the primary competitor for the 737NG series remained only the A320 family.

In July 2019, there were 46 Boeing 737-200s in service, mostly with "second and third tier" airlines, and those of developing nations. The first BBJ2 was delivered on February 28, 2001. But even if deliveries resume this year, it expects airline customers to take only about half of the stored jets by the end of 2021. [43][44] Consequently, in that year carriers retired Boeing 737 Classic aircraft to reduce fuel consumption; replacements consisted of more efficient 737 Next Generation or A320 family aircraft. [1][32], Nineteen 737-200s, designated T-43, were used to train aircraft navigators for the U.S. Air Force. The "Classic" models are the 737-300, 737-400 and 737-500. [35] Boeing said that the 737 Next Generation (NG) program had begun on November 17, 1993. En una grabación de cabina, se puede escuchar a The MAX-7 will replace the 737-700, the MAX-8 will replace the 737-800 and the MAX-9 will replace the 737-900ER. Questi nuovi motori, certificati dalla FAA nel 1996 per una spinta di circa 12 mila chili (26.400 libbre), sono caratterizzati dal basso consumo di carburante e dai ridotti costi di manutenzione. These engines were expected to be 10-12% more efficient than the CFM56-7B engines on the 737 Next Generation series. [66][67] Overhead bins which move have been installed. El Boeing 737 MAX és un avió de fuselatge estret dissenyat i fabricat per Boeing Commercial Airplanes.Es tracta de la quarta generació de Boeing 737 i succeí al Boeing 737 Next Generation (NG).. Fou llançat el 30 d'agost del 2011 i emprengué el seu primer vol el 29 de gener del 2016. The legs are covered by partial doors, and "brush-like" seals aerodynamically smooth (or "fair") the wheels in the wells. In November 1993, Boeing began the Next Generation program. ", "Alaska Airlines and Horizon Air Aircraft Information. The 737-200 Advanced can also fly further than the 737-200. The Boeing 737 MAX is the fourth generation of the Boeing 737, a narrow-body airliner manufactured by Boeing Commercial Airplanes (BCA). They were changed into cargo planes by the airlines that owned them. [8] It began designing the 737 on May 11, 1964. The original design was too small to require this, and adding a fuel dump system to the later, larger variants would have incurred a large weight penalty. (Project 2A2H).

These burned much less fuel and made much less noise than the Pratt & Whitney JT8D engines which were used on the -100 and -200. The only types of 737 that Boeing is still making are the -700, -800 and -900ER. Seating is as follows: A319: 141. A Boeing 737 a világ legnépszerűbb közepes hatótávolságú, keskeny törzsű utasszállító repülőgépe. [11], On April 5, 1965, Boeing announced that United Airlines had ordered 40 737s. This aircraft was 2,843rd 737 built. After 271 aircraft were made at Boeing Field, Boeing moved the 737s to Renton. After 40 years, in March 2008, the final 737-200 aircraft in the U.S. flying scheduled passenger service were phased out, with the last flights of Aloha Airlines. [18][19] It was the first aircraft to have, as part of its initial certification, approval for Category II approaches,[20] which refers to a precision instrument approach and landing with a decision height between 98 to 197 feet (30 to 60 m). The -700 seats 126 passengers in a two-class or 149 passengers in a one-class layout.

It flew from Chicago to Grand Rapids, Michigan. Only 30 737-100s were ordered and delivered. The BBJ1 was similar in dimensions to the 737-700 but had additional features, including stronger wings and landing gear from the 737-800, and had increased range over the other 737 models through the use of extra fuel tanks. Boeing called these models the Boeing 737 Classic series. A hull loss accident is when the plane is damaged so much it can not be used anymore, or if the plane was completely destroyed. Boeing Capital Corporation (BCC) Another source tells KOMO News that Boeing was quick to report the issue to the FAA last week. [24] Los tres modelos de la nueva variante son el 737 MAX 7, el 737 MAX 8 y el 737 MAX 9, los cuales se basan en el 737-700, −800 y −900ER respectivamente, [ 25 ] que a su vez son los modelos con mayor éxito de ventas de la gama 737 Next Generation. All these changes gave the aircraft a boost to payload and range, and improved short-field performance. The T-43 was retired by the Air Education and Training Command in 2010 after 37 years of service.[138]. The third generation "NG" series: 737-600, -700, -800 and 900 series, also the military C-40 and P-8, launched late 1993. Los aviones Boeing 737 MAX empiezan a recuperar la confianza perdida. The -400F was not delivered by Boeing. Reprinted in the AIAA Journal of Aircraft, Vol.3 No.6, November/December 1966, pp.524-528. [64] If 700 pounds of weight is taken off a Boeing 737-800, it burns 0.5% less fuel. [1][73] Many 737-200s are still used by airlines. The aircraft were delivered between May 1982 and October 1983.[33]. Boeing 757 = 5.000 kgs/h. [30] The 737-400 made the fuselage even bigger (by 10 ft (3.0 m)). A ventral tailskid was installed to prevent tailscrape damage on over-rotation, the FCTM shows that the -400 has the greatest risk of tailstrike of all the series of 737. Engineer Joe Sutter relocated the engines to the wings, lightening the wing structure and simplifying the accommodation of six-abreast seating in the fuselage. Leva sendo fabricado por Boeing dende 1967. All Nippon Airways was the launch customer for the -700ER. [111] Contrary to popular belief, these windows were not intended for celestial navigation[112] (only the military T-43A had a sextant port for star navigation, which the civilian models lacked. The 737 Next Generation series introduced a six-screen LCD glass cockpit with modern avionics but designed to retain crew commonality with previous 737 generations. Launch customer Hapag-Lloyd Flug (now TUIfly) received the first one in April 1998. Boeing 737 é uma família de aeronaves narrowbody bimotor turbofan, desenvolvida e fabricada pela Boeing.Criado para ser um avião com custos de operação mais baixos, o 737 tornou-se uma série com dez variantes, cujas capacidades de 85 a 215 passageiros. Boeing 737 MAX je čtvrtá generace dvoumotorového proudového úzkotrupého dopravního letounu Boeingu 737 na krátké a střední tratě vyvinutá Boeingem jako reakce na úspěch Příští generace (Next Generation) Boeingů 737-700, 800 a 900. Boeing 767 = 5.200 kgs/h Awalnya pesawat ini merupakan pengembangan versi murah dari Boeing 707 dan Boeing 727 … Getting rid of unneeded fuel helps to get to a safe weight for the plane to land. Percorsi brevi hanno, in proporzione, consumi più elevati perché 1/3 del carburante viene bruciato durante il decollo. The popularity of the Next-Generation 737, combined with new innovation, launched our 737 MAX Family. [180] Similar rudder issues led to a temporary loss of control on at least five other 737 flights before the problem was ultimately identified. This aircraft's cabin is pressurized to a simulated 6,500-foot (2,000 m) altitude. As of January 1, 2001, 1,945 are in service. An additional pair of exit doors and a flat rear pressure bulkhead increased its seating capacity to 180 passengers in a two-class and up to 220 passengers in a one-class configuration. In 2011, Boeing said that it was working on the 737 MAX program. It converts old 737-800 passenger jets to dedicated freighters. ", "Boeing firms up 737 replacement studies by appointing team. However, it was also difficult to fit these engines to the aircraft. It was first used by an airline in February 1968. The launch customer Southwest Airlines took the first delivery in December 1997. ", Dekkers, Daniel, et al. The 737 Next Generation is made up of the -600, -700, -800, and -900ER models. [113] With modern avionics, the windows became redundant, and many pilots actually placed newspapers or other objects in them to block out sun glare. [1] The 737-600 replaced the 737-500 and is similar to the Airbus A318. [117], 737s are not equipped with fuel dump systems. At first, Boeing was making it to be a shorter, cheaper airliner than its 707 and 727. [82] Boeing launched the 737-700ER on January 30, 2006. [4], Boeing had been studying short-haul jet aircraft designs, and saw a need for a new aircraft to supplement the 727 on short and thin routes. [33] The 737-500 flew for the first time on June 30, 1989. [120], The 737 is unusual in that it still uses a hydro-mechanical flight control system, similar to the Boeing 707 and typical of the period, that transmits pilot commands to control surfaces by steel cables run through the fuselage and wings rather than by an electrical fly-by-wire system as used in all of the Airbus fleet and all later Boeing models. The dark circles of the tires are clearly visible when a 737 takes off, or is at low altitude. It began using the -200 Advanced on May 20, 1971. I can only answer for the 747 and I’ll narrow that further to the 747–8. [166][verification needed], The 737 had the highest, cumulative orders for any airliner until surpassed by the A320 family in October 2019. Passenger flights in the U.S. are expected to resume before the end of the year. Seating is as follows: A319: 141. It got its first aircraft on May 15, 2001. [108] The 737 Classics had CFM56 turbofan engines. They ordered 25 aircraft in 1986. They are fitted at the end of the wing and help the engines to burn less fuel because they reduce drag. Since entering service in 1968, the 737 has carried over 12 billion passengers over 74 billion miles (120 billion km; 65 billion nm), and has accumulated more than 296 million hours in the air. At that time, twelve customers had ordered the package for more than 250 airframes. After the Boeing 737 Next Generation planes were brought into service, Boeing named the 737-300/-400/-500s the 737 Classic series. It is based on earlier 737 designs, with more efficient CFM International LEAP-1B engines, aerodynamic changes including its distinctive split-tip winglets, and airframe modifications. La mayor aerolínea europea de bajo coste ha encargado este jueves 75 unidades del 737 MAX a Boeing, lo que supone ampliar su pedido hasta un total de 210 aviones. The leading-edge slats and trailing-edge flaps were adjusted. The passenger capacity of the aircraft was increased to 149 by extending the fuselage around the wing by 9 feet 5 inches (2.87 m). Ryanair ha firmado este jueves un acuerdo con Boeing para la compra de 75 nuevos aviones 737 MAX-8200, lo que aumenta a 210 su pedido en firme, con un valor total de más de 22.000 millones de dólares (unos 18.000 euros aproximadamente).
