Fu outpost, enlisted 1968. 1977 graduated from Northwestern Polytechnical University majoring in aerodynamics. He has been a mechanic, team leader, editor and director, and is now the deputy editor-in-chief of Air Force Aviation magazine. His main works are Handbook of Future Aircraft and Looking Up at the Sky-Past, Present and Future of Military Aircraft. He has published thousands of popular science articles and served as a special commentator for many CCTV columns for a long time. He was once rated as an advanced scientific and technological worker of the Air Force and an excellent national defense science writer. My book Look at the Clouds won the Sixth People's Liberation Army Book Award.

Fu Qianshao is a military expert of China Air Force and an important national figure. Resumes of important national figures will be introduced in detail in official website of his unit; Their resumes are private and protected.
As we all know, the US military has two kinds of fourth-generation stealth fighters: the F-22 and the F-35. The F-35 is mainly used to perform frontline support, target bombing, air defense interception and other tasks, and exhibits three derivative versions: A, B and C.
According to Fu Sentinel, although F-35A, F-35B and F-35C all belong to the F-35 series, they are three different fighters used in different services. F-35A is an American air force type, which takes off and lands in the conventional way of taxiing at land airports. The F-35C is a conventional carrier aircraft used on the aircraft carrier of the US Navy, which adopts catapult take-off and recovery. The F-35B is a vertical/short-range take-off and landing type used by the Marine Corps, and its take-off and landing platform is mainly amphibious assault ship.
Fu Sentinel said that when the US Air Force, Navy and Marine Corps put forward the demand for the next generation of fighters, they were ready to make their own plans. The Pentagon thinks that it is too expensive to develop three different fighters at the same time, so it requires that these plans be combined into a joint attack fighter project, that is, a modular basic platform is designed, and then three sub-plans are subdivided according to the different needs of the three services and arms for this platform.
"So F-35A, F-35B and F-35C are actually three different types of aircraft, which are different from the concept of upgrading and developing different types of aircraft such as A-type, B-type, C-type and D-type. From the beginning, it was divided into three models: A, B and C, and its functions and usage methods were quite different. "
The biggest feature of the F-35B is its vertical/short takeoff and landing capability. In fact, it is the most advanced vertical/short-range take-off and landing fighter in the world at present, and it is also the first vertical/short-range take-off and landing fighter with stealth capability and supersonic flight capability in the world. In the past, such military aircraft developed in parallel were all subsonic or high subsonic and could not fly at supersonic speed.
The F- 135 engine equipped with the F-35B is the jet engine with the highest thrust in the world at present, and its afterburning thrust can reach about 190 kn. This type of engine adopts a long-range lift system driven by a shaft to realize the vertical/short takeoff and landing of the aircraft. The three-bearing tail nozzle can be deflected downward by more than 90 degrees, and the shaft-driven lift fan is installed vertically behind the cockpit. This two-stage counter-rotating fan has a nozzle, which can deflect the jet forward or backward. When the F-35B takes off and lands, the tail nozzle of the F- 135 engine deflects downward, driving the lift fan to exhaust downward. The combination of the two can lift the plane. Under such engine conditions, the F-35B can take off, hover and land vertically.
As an air force expert, Fu Sentinel said that any aircraft has advantages and disadvantages, and the advantages and disadvantages of the F-35B all come from the above characteristics. "Its dependence on the landing site is very weak. It can not only run, take off and land in the conventional way at the airport, but also board the ship when necessary. Unlike the Air Force F-35A, it can take off without using an airport, while the naval ship-borne F-35C cannot fly without an ejection device. Imagine that once the landing site is attacked in the war, the F-35A cannot take off, while the F-35B can use the runway between two craters for short-distance running and take off directly, which is very flexible to use.
