The 737-800 is the most widely used narrowbody aircraft and competes primarily with the Airbus A320.[70]. [64] If 700 pounds of weight is taken off a Boeing 737-800, it burns 0.5% less fuel. [14] Boeing cancelled the Boeing Supersonic Transport and started making less Boeing 747s. There have been no orders that have not been delivered (as of 2010). "Hub caps" complete the aerodynamic profile of the wheels. Before the aircraft can fly again, repairs must be implemented and airlines' training programs must be approved. 215 passengers can fly if the plane only has one class. [52], On July 20, 2011, Boeing said that they were working on a new 737 version, which would have the CFM International LEAP engine. The 737 Classic planes also had some improvements made to the wings. [101][102] The Max 10 has similar capacity as A321XLR, but shorter range and much poorer field performance in smaller airports than A321XLR. [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. Development began in 1979 for the 737's first major revision, which was originally introduced as the 'new generation' of the 737. [16] On December 15, 1967 the Federal Aviation Administration said that the -100 was allowed to fly with passengers. The wheels do not have a door to close over them. It was first ordered by Lufthansa in 1965. The Boeing 737 Classic is the name of the 737-300/-400/-500. [8] The engine nacelles were mounted directly to the underside of the wings, without pylons, allowing the landing gear to be shortened, thus lowering the fuselage to improve baggage and passenger access. The 737's main rival is the Airbus A320 family. Boeing 767 = 5.200 kgs/h N462BC. The primary flight controls have mechanical backups. The 6,000th 737 was delivered to Norwegian Air Shuttle in April 2009. The plane could now carry 149 passengers, because the fuselage of the plane was made bigger. [54] The prototype −300, the 1,001st 737 built, first flew on February 24, 1984 with pilot Jim McRoberts. Many countries operate the 737 passenger, BBJ, and cargo variants in government or military applications. The 737 Classic series featured CFM56 high bypass turbofan engines, which yielded significant gains in fuel economy and a reduction in noise over the JT8D low bypass engines used on the 737 Original series (−100 and −200), but also posed an engineering challenge given the low ground clearance of the Boeing 737 family. [24] The improved version, the 737-200 Advanced, was introduced into service by All Nippon Airways on May 20, 1971.[25]. The 737 MAX 7, MAX 8 (including the denser, 200-seat MAX 200), and MAX 9 replace the 737-700, -800, and -900 respectively. 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. The first aircraft was delivered to Scandinavian Airlines on September 18, 1998. It entered service in 1968. Boeing Business Jet versions are produced since the 737NG, as well as military models. Percorsi brevi hanno, in proporzione, consumi più elevati perché 1/3 del carburante viene bruciato durante il decollo. It competed primarily with MD-80, later its derivative MD-90 and the newcomer Airbus A320 family. [18] Lufthansa was the only significant customer to purchase the 737-100 and only 30 aircraft were produced. [35] Winglets can help a plane burn up to 5% less fuel. The original 737 continued to be developed into thirteen passenger, cargo, corporate and military variants. The National Transportation Safety Board determined that the accidents and incidents were the result of a design flaw that could result in an uncommanded movement of the aircraft's rudder. The first BBJ rolled out on August 11, 1998 and flew for the first time on September 4. As of December 2019, 15,156 Boeing 737s have been ordered and 10,571 delivered. It made its roll-out on March 7, 2017, and first flight on April 13, 2017;[96] It was certified by February 2018. This page was last changed on 8 July 2020, at 08:35. After the Boeing 737 Next Generation planes were brought into service, Boeing named the 737-300/-400/-500s the 737 Classic series. Because the engine is close to the ground, 737-300s and later models are more prone to engine foreign object damage (FOD). These new brakes have been allowed by the Federal Aviation Administration. [68], The Boeing 737-800 was a stretched version of the 737-700 launched on September 5, 1994. The 737-900ER (Extended Range) is the newest and largest variant of the 737NG generation. The first generation Original series 737 cabin was replaced for the second generation Classic series with a design based on the Boeing 757 cabin. In 1970, Boeing only got 37 orders for 737s. Boeing 727 = 5.670 kgs/h. The 737-600, 737-700 and 737-800 planes were planned. [84], In July 2008, Delta Air Lines got the first -700 that had Messier-Bugatti's carbon brakes.[64]. However, 149 can fit in if the aircraft only has an economy class. [90] Lion Air and others have made orders for 737 MAX planes. The -700 seats 126 passengers in a two-class or 149 passengers in a one-class layout. [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. O Boeing 737 MAX é uma aeronave de fuselagem estreita, bimotora e turbofan desenvolvida e produzida pela Boeing como a quarta geração da família 737, sendo o sucessor do Boeing 737 Next Generation.Ele é baseado no projeto do 737 anterior, com os motores mais eficientes CFM International LEAP-1B, melhorias aerodinâmicas (incluindo winglets de ponta dupla) e modificações na fuselagem. It is painted in the silver & red, 27286/2528: 737-3Q8 registered N759BA on static display at the, This page was last edited on 12 December 2020, at 21:21. The 737-400 was launched in 1985 to fill the gap between the 737-300 and the 757-200. 737 Classic: 737-300, 737-400, 737-500. Norwegian pilots, Boeing 737 . [77], The 737-500 was finished 1987. It also wanted to make improvements to make the aircraft more modern. The prototype 737-800 was finished on June 30, 1997 and first flew on July 31, 1997. This meant that the wheels were not being pushed down onto the ground very much, which made the brakes less useful. A winglet lift credit, achieved through additional winglet testing, that reduces the minimum landing-approach speeds. 324 people have died in hijackings. By doing this, Boeing kept enough money to keep the 737 project going. Rispetto al CFM56-3C montato sui 737-300, -400 e -500, il CFM56-7 offre una spinta maggiore del 10%. Note that the 2020 deliveries consist of NG-based variants and include no 737 MAXs. Oct 19, 2017 - Explore Alfonso Saavedra's board "BOEING 737", followed by 105 people on Pinterest. Its main rival is the A319. A "thrust reverser" is a part of the engine of a plane. Os MAX visavam a concorrer com o A320 Neo, apresentado meses antes pela Airbus. [83] "ER" stands for "extra range". ", Sweetman, Bill, All mouth, Air & Space, September 2014, p.14, CS1 maint: multiple names: authors list (, Dekkers, Daniel, et al. [51], The wing also incorporated changes for improved aerodynamics. ", "Boeing officially launches re-engined 737. [76] The 737-300 series was made until 1999. MTOW, Sea Level, International Standard Atmosphere, "German Airline Buys 21 Boeing Short-Range Jets.". [160], By 2006, there were an average of 1,250 Boeing 737s airborne at any given time, with two either departing or landing somewhere every five seconds. [6] The Next Generation series helped make sure the 737 stayed the bestselling[42][43][44] airliner family since it first flew. The 737-500 (originally known as the 737 Lite and the 737-1000) combined the original length fuselage of the -200, with the various improvements of the -300 and -400. The third generation "NG" series: 737-600, -700, -800 and 900 series, also the military C-40 and P-8, launched late 1993. Piedmont Airlines was the launch customer. Kone on niin yleinen, että voidaan sanoa niitä olevan joka hetki vähintään 1 250 kappaletta ilmassa. The launch customer Southwest Airlines took the first delivery in December 1997. It was then certified by the FAA on December 21, 1967. African airline orders kept the production running until the 1978 US Airline Deregulation Act, which improved demand for six-abreast narrow-body aircraft. There are two on each side. The 747–8 is about 20% more efficient than the 747–400. [16] Detailed design work continued on both variants simultaneously. [53] On August 30, 2011, Boeing said that a new 737 would definitely be launched. Only 30 737-100s were ordered and delivered. [84], The 737 MAX 7, a shortened variant of the MAX 8, was originally based on the 737-700, flying 1,000 nmi (1,900 km) farther and accommodating two more seat rows at 18% lower fuel costs per seat. [100] The variant configuration with a predicted 5% lower trip cost and seat cost compared to the A321neo was firmed up by February 2018, and by mid-2018, the critical design review was completed. 737-500 FF 30 Jun 1989 388 Built, 199 In service. It was the highest-selling commercial aircraft until being surpassed by the competing Airbus A320 family in October 2019, but maintaining the record in total deliveries. They improve fuel efficiency by up to 5% through lift-induced drag reduction achieved by moderating wingtip vortices. However, the 737 has become a family of nine different models. Over 4,500 are still being used by airlines. They were used as Maritime reconnaissance (MPA)/transport aircraft, fitted with SLAMMAR (Side-looking Multi-mission Airborne Radar). They chose the CFM56-3B-1 high-bypass turbofan engine to power the aircraft, which yielded significant gains in fuel economy and a reduction in noise, but also posed an engineering challenge, given the low ground clearance of the 737 and the larger diameter of the engine over the original Pratt & Whitney engines. The -200 was finished on June 29, 1967. [87] Entry into service with launch operator Southwest Airlines was expected in January 2019' but the airline deferred these orders until 2023–2024. 126 passengers can fit onto the plane. ", "Bombardier’s Win May Prod Airbus, Boeing to Upgrade Engines. They also moved some parts of the engine, which would normally go on the bottom, to the sides. Boeing 737 on Boeingin vuonna 1967 esittelemä kaksimoottorinen lyhyiden ja keskipitkien matkojen kapearunkoinen matkustajalentokone.Se on ilmailun historian myydyin kaupallinen suihkukone..
