Are 73H and 738 the same model?

In the Boeing family, 73H and 738 are both modifications of Boeing 737 regional aircraft.

The model is 73H, and the number of seats is 162- 189. Some passenger and cargo mixed seats 69-79 are 737-800 (winglet) passenger planes manufactured by Boeing Company. Boeing 737-800 is the main 73H model of domestic airlines, with winglets, passenger and cargo mixed and modified, the number of seats is reduced by about half, and the rear cabin is changed into a warehouse. The flight economy of winglet has been greatly improved, and it has been favored by airlines in recent years.

Model 738 is the standard model of Boeing civil aircraft 737-800.

Boeing series aircraft is a very successful product series of civil transport aircraft under Boeing Company of the United States. By March of 20 12, this series has owned Boeing 40, Boeing 80, Boeing 2 1 1, Boeing 3 14, Boeing 247, Boeing 307, Boeing 707 and Boeing 765438.

2707 (Boeing 2707 is the first supersonic passenger plane plan developed by the United States. According to the government contract, Boeing began to design aircraft in Seattle. However, due to the rising cost and unclear market demand, the whole plan was suspended before the construction of 197 1 two prototypes.

1930, Boeing began to develop all-metal passenger aircraft, which is the famous Boeing 247 in aviation history. All-metal structure, streamlined appearance, retractable landing gear and lower single wing structure. The cruising speed of the plane is 248km/h, the range is 776km, the passenger capacity is 10, and the portable mail is 18 1kg. This plane has comfortable seats, a bathroom and an air hostess. 1933 Boeing 247 made its first flight successfully. The seating conditions and speed of Boeing 247 have been greatly improved compared with ordinary passenger planes, so it is very popular with airlines and has become a hero in the history of American civil aviation transportation.

Boeing 307 is the first passenger plane in the world that uses compression chamber completely. At that time, its flying height could be 20,000 feet higher than that of an ordinary passenger plane without a compression cabin (flying height 5000 ~ 10000 feet), and it was said that it could "fly above the weather". It has five crew members, can carry 33 passengers, and has a sleeper nearly 12 feet wide. This is also the first land-based aircraft to add flight technicians to the crew.

Boeing 377 is Boeing's last propeller airliner. During World War II, Boeing tried to develop a civil aircraft. The company developed a Boeing 377 with a double cabin by using the wings and engines of the B-29 bomber with a brand-new fuselage. Originally intended to enter the large luxury passenger aircraft market, it still ended hastily because of poor sales. ?

Boeing 707 is a four-engine long-range jet transport aircraft developed by Boeing Company of the United States. The prototype made its first flight in July 1954. The prototype was KC- 135 aerial tanker developed for the US Air Force. With the approval of the US Air Force, the company successfully developed the Boeing 707 civil airliner on the basis of KC- 1957 and delivered it on 1958.

The main models of Boeing 707 are 707- 120, -220, -320 and -420. China Civil Aviation once purchased 10 320C, which was also converted into a special aircraft. Boeing 707*** ordered 10 10, the production line was closed on 199 1, and the last military model was delivered in May 1992. The aircraft is equipped with four JT3D-7 turbofan engines, with a single thrust of 84.48 kN, four cabin passengers and a passenger capacity of 2 19.

Boeing 7 17 is Boeing's smallest twin-engine jet, originally named MD-95, designed for the 100 seat market. Boeing Company received the first order on 1995, and officially put it into use on 1999. 7 17 is the third generation successor of Douglas DC-9. Boeing Company stopped the production of 7 17 in May 2006, ending the long history of assembling passenger planes in Boeing Long Beach Factory.

Boeing 727 is the second jetliner of American Boeing Company after 707. It was tested on 1963. The number of passengers is 145 (economy class and business class) or 189 (first class). Driven by three turbojet engines, the fuselage components and other parts are the same as 707. The main market is the inland trunk lines of the United States. Boeing 727 adopts a trident-like design, and all three engines are installed at the tail of the aircraft. The last 727 was delivered at 1984. The total output is 1, 832.

Boeing 737 series aircraft is a short-range twin-engine jet aircraft produced by Boeing Company of the United States. Boeing 737 has been selling well for more than 40 years since it was put into production. Boeing 737 became the most successful series of narrow-body passenger aircraft in the history of civil aviation. Known as the most successful civil airliner in the history of world aviation. On March 5th, 20 10, the Civil Aviation Administration of China issued a warning to domestic airlines that more than 450 Boeing 737 series passenger planes operating in China had potential safety hazards.

Boeing 747, also known as jumbo jet, is a two-cabin four-engine aircraft, one of the most recognized passenger aircraft in the world, and the first wide-body civil aircraft produced in the world, which is manufactured by Boeing Civil Aircraft Group of the United States. The prototype size of Boeing 747 is twice that of Boeing 707, which was widely used in 1960s. 1965 was developed in August. Since 1970 was put into use, it has been the largest civil aircraft in the world, monopolizing the market of large civil transport aircraft. Before A380 was put into use, Boeing 747 kept the record of the highest passenger capacity in the world for 37 years. ?

Boeing 757 is a medium-sized single-channel narrow-body civil airliner developed by Boeing Company of the United States. Used to replace Boeing 727 and supplement Boeing 767 on routes with few tourists. Boeing 757 was put into use on 1983 and stopped production on1kloc-0/.08 in 2005.

Boeing 767 is a medium-sized wide-body airliner developed by Boeing Company of the United States to compete with Airbus A3 10. Both 767 and 757 have the same cockpit design, so it is easy for crew and maintenance personnel to master both aircraft at the same time. 767 and 757 are the first cockpit operated by two people in Boeing civil aircraft and the first electronic flight instrument in Boeing passenger aircraft. The first model of 767 was -200, and later a longer -300 was produced. There are also -200ER, -300ER and -400ER dedicated to long distance.

Boeing 777 is a twin-engine wide-body airliner developed by Boeing Company of the United States. 1990 65438+/kloc-0 officially started on October 29th1994 June 12 1 Boeing 777 made its first flight,1April 99519 obtained the European joint airworthiness certificate. Boeing has signed risk-sharing partnership agreements with Mitsubishi, Kawasaki and Fuji Heavy Industries of Japan, and Japan will undertake 20% of the 777 structural work. ?

Boeing 787, also known as "Dreamliner" (English), is a medium-sized twin-engine wide-body medium and long-range transport aircraft. It is the first brand-new aircraft launched by Boeing in 14 after Boeing started the Boeing 777 project in 190. It was developed by Boeing Commercial Aircraft Group (BCA) and officially listed in April 2004. After many delays, the test flight was successful in 65438+February 65438+May, 2009, which marked that the manufacturing project of the 787 aircraft entered the final stage before delivery, and it was delivered on 20 10. 2011At 0: 20 on September 27th, the Boeing 787 Dreamliner was delivered to ANA.
