McDonnell Douglas DC-9/ MD-80 andAirbus A320It is a jet airliner of the same class (100-200 seats), and since its first flight in 1967, a total of more than 2018 aircraft with various variations have been manufactured by February 2 while making continuous improvements for half a century., Production continues with a large number of back orders.It is the largest series of jet airliners in history and one of the best-selling and long-selling commercial transport aircraft in history.
Assuming that it will be used on short-distance routes that frequently take off and land between small and medium-sized airports in poorly equipped regions and airports in large cities with strict noise regulations, takeoff and landing on short runways and cruising altitude in a short time To achieve the rise toWingRelatively powerfulHigh lift deviceIn addition to being equipped with, the main landing gear is a type that fits into the "dent" of the aircraft, and the side of the wheel is exposed even when it is retracted, giving it a natural cooling effect by introducing outside air during flight.
さ ら に,Air steer(Built-in aircraftTarup) Can be installed as an option, and various technologies and equipment have been introduced to realize low-cost operation on short-distance routes.It is also the first Boeing jet airliner to be able to carry two passengers.
Rear engineBoeing's previous work, which was said to be a three-shot ceremonyBoeing 727Unlike the engine, the engine is a twin-engine engine with two engines mounted under the main wing, one for each, and the design emphasizes maintainability by avoiding a special engine layout.一方の胴体は設計費と生産単価の低減のため、先行した1と同じ設計（遡れば2年就航の第一世代ジェット旅客機であるOne fuselage is the same design as the preceding 727 (back to 1958, the first-generation jet airliner) to reduce design costs and unit production prices.Boeing 707Since then, the design) has been diverted. DC-9より太くてA320よりわずかに狭く、標準的なThicker than DC-XNUMX and slightly narrower than AXNUMX, standardEconomy classIf so, you can place 6 rows of seats across the aisle.
Over the years, it has been continuously updated by introducing various new technologies, and is widely operated by airlines around the world as the main aircraft for short-distance routes.The latest model is not limited to short-haul routes大西洋It is expected to enter service on medium- and long-distance routes such as transatlantic flights, and in addition to being equipped with various equipment for offshore flights,ETOPSThere are also certified equipment.
In addition, for entertainment such as personal TVs, AC outlets, USB power supplies, etc., for senior seats on long-distance international flightsIn-flight mealIt is also possible to select a galley that corresponds to the service.
1964In addition, many remained on the local lineDouglas DC-4,Conveyor 440Propeller passenger planes such asLockheed L-188It was a rival company at that time as a small short-distance jet airliner with a capacity of 100 passengers to replace turboprop airliners such asDouglasDevelopment has begun to compete with the DC-9.
However, most of the major American airlines at that time were already DC-9 orBAC 1-11What was left in the marketUnited airlinesとEastern AirlinesHowever, the latter has made clear its intention to adopt DC-9.This situation forced Boeing to develop without the strong backing of American airlines.
1965ToLufthansaAlthough it was decided to continue development by receiving an order for 21 aircraft from, this was far less than the number of aircraft that had been started after receiving orders for 80 to 100 aircraft.For this reason, after presenting the best possible conditions, such as offering to United Airlines to "lease the 727 at a rate almost free of charge as a connection to delivery," 40 aircraft (and 30 aircraft as an option). Succeeded in getting an order for.
1967First flight in April, route service1968It started with Lufthansa in February.Initially, sales were sluggish due to the lack of performance of the prototype, the opposition of the Pilot Association (ALPA) to the crew of two, and the shortage of seats of -2, but the fuselage was extended-2 and the interior was upgraded- Since it was improved in response to the demands of airlines such as the introduction of 100 Advanced, its performance has been recognized and it has been introduced by airlines all over the world.
After the production of the early -100, -200, the engine has a high bypass ratioTurbo fan-300, -400, -500 replaced with1980 eraAppeared at the beginning.Due to its small turning ability, the main wing is still redesigned to improve efficiency.777"Next-Generation (Next Generation / NG)" of -600 type to -900 type using the technology of737MAXThe state-of-the-art series called "" is being produced, and as of January 2014, it is a best-selling machine with a total of 1 ordered machines and a total of 11575 machines produced.
The series is2011May 12In addition, the 7,000th 737 (-800) was handed over to flydubai.また通算7,500機目は、2013年3月20日にThe XNUMXth aircraft will be released on March XNUMX, XNUMX.Malindo AirTo (B737-900ER), the 8,000th aircraft in total will be on April 2014, 4.United airlinesIt was handed over to (B737-900ER) respectively.
737 Original -100 / -200 (1st generation)
This engine is directly attached to the main wing without going through a pylon, which reduces the weight and keeps the ground clearance low.Also, this engine has a low bypass ratio (bypass ratio 0.96-1.00), soReverse injection device(Thrust reverser) has a structure that covers the nozzle at the rear of the engine.
The -100 is the smallest aircraft in the entire series,胴体The length of is 28.6m,Cruising distanceIs 3,440 km.Almost all of the production aircraft were operated by Lufthansa, as most of the orders were concentrated on the -200.
-200 type is more than -100 type胴体The aircraft is 1.9m longer, 30.5m, and has a longer cruising range (about 4,000km), but it is basically the same aircraft. For the -200 type, a cargo door was added to the left front part of the fuselage as a combination machine (freighter mixed loading machine) model, and the -200C type (-200 Convertible) was prepared so that the front seats could be easily removed.カナディアン・ノース航空やCanadian North AirlinesNolinor Aviationな どカナダAirline has introduced the -200C type as a local route, but hard ice and gravel often remain on the runway at unequipped airfields, so if the gravel that the wheels bounce off hits the aircraft Modifications were made such as strengthening the front leg cover and changing it to a guard type so that it does not occur, and installing a duct that blows compressed air at the bottom of the engine in order to blow it off before the engine sucks in foreign matter.Aircraft with the same specifications were delivered to African countries, and aircraft delivered to the Republic of Nauru (Nauru Airlines) were also in Japan.
1971Introduced an improved version (-200 Advanced) that has been upgraded to the latest model, such as improving takeoff and landing performance and introducing an overhead wedge in the interior design of the aircraft.1988Production continued until.アメリカ空軍も、-200Advanced型を元にした航法練習機をThe U.S. Air Force also has a navigation training aircraft based on the -XNUMX Advanced model.T-43In addition to being adopted under the name ofIndonesian Air ForceIs the oceanPatrol aircraftThe aircraft modified as "Surveyor" is operated under the name of "Surveyor".
The number of production of -100 type is 30, and 200 type is 1,114 including the initial type and the improved type.
Incidentally,Japan-200 and -200 Advanced are available on airlinesAll Nippon AirwaysとJapan Short Distance Air,Southwest AirlinesIntroduced, contributing to the jetting of remote island routes and local routes,2003Used up to.Also,Hong Kong Dragon Airlines,Nauru airlines,Philippine AirlinesEtc. were used as equipment for entering Japan.
737 Classic -300 / -400 / -500 (2nd generation)
With the aim of responding to the points to be improved and the requests received in the first generation, further improving the problems in the aircraft design, and competing with the McDonnell Douglas MD-1 series.1970 eraDevelopment began in the second half and went into service in the early 1980s.
It is one of the completed models that Boeing aimed at at that time, and since it is a representative aircraft of the 737, "737 Classic(In addition, -100 type and -200 type may be included).
737NG -600 / -700 / -800 / -900 (3rd generation)
The -400 / -800, which is an extension of the -900, and the -900ER, which has a long cruising range that allows it to cross the Americas without landing, were also introduced.The aircraft of this generation is "737 Next Generation(737NG) ”.
After the introduction of this series, Boeing has almost the same number of seats as -600.717 seriesAnd has almost the same number of seats (-900) and cruising range as -200757 seriesThe production of.
