The US Air Force is responsible for strategic deterrence B-2A stealth strategic bomber originally had a procurement scale of 21. On December 10, the US Air Force announced that an accident occurred during a forced landing, which eventually led to only 18 B-2As in the US Air Force being used for combat readiness. A fire occurred during the U.S. Air Force B-2A crash landed, which may have caused damage to the runway, as the U.S. Air Force announced that the incident's Whiteman Air Force Base was closed until December 16. Just five days after the US Air Force B-2A "dog gnaws the ground", bad news came from the United States that the F-35B fighter , a fifth-generation fighter, also appeared "dog gnaws the ground", and was photographed by the "busy guy".
F-35B Lightning II fighter is a fifth-generation fighter with short-range/vertical take-off and landing capabilities. It is currently built at the Fort Worth factory of Lockheed Martin, the United States. The F-35A and F-35C fighters are also built. The F-35A is a conventional take-off and landing platform. The F-35C has the ability to use on the aircraft carrier . The US Navy has two aircraft carriers carrying the F-35C Lightning II fighter aircraft that have performed combat cruise operations, and they are both performing missions at the doorstep of China. F-31A, F-35B and F-35C belong to the JSF joint attack aircraft developed by Lockheed Martin in the United States. It is expected to have an order size of 6,000 aircraft. Recently, Lockheed Martin in the United States also specially announced a promotional video of the construction of 1,000 stealth fighter jets.
According to the video released by the United States, the "dog gnaw" F-35B belongs to a product that has not been delivered yet and belongs to the property of Lockheed Martin . At that time, the F-35B was conducting a test flight subject after being taken off the line. The F-35B did not control the balance when it was vertically landed, and the front landing gear was broken, and the fuselage rotated 360 degrees in the horizontal plane. When the F-35B fighter lost control, the pilot of the F-35B fighter chose to escape. With a loud bang, the ejection seat "zero-zero ejection" flew out, and the pilot finally landed safely. After the accident, senior executives of Lockheed Martin ordered a thorough investigation of the accident.
From the video, it is very likely that the pilot's control is problematic, because it is obvious that the fuselage is leaning forward when landing. The vertical landing of the F-35B is mainly achieved through engine deflection and lift fan. It is very likely that the thrust mismatch between the engine tail nozzle and lift fan leads to the fuselage imbalance. 202212207/Aviation Vision/AZ, in addition to having the ability to land vertically, the F-35B fighter also has the ability to take off at short distances. Like vertical landing, it also uses the engine tail nozzle and lift fan to achieve functions. The F-35B Lightning II fighter is very complex, and the lift fan components are developed by the British Rolls-Royce, and the UK accounts for 30% of the US JSF joint attack aircraft project. The accident occurred before the
F-35B fighter was shipped. This was the first time in the JSF joint attack construction process. The first mass-produced model of the Russian Su-57 fighter crashed before it was delivered, which delayed the Su-57 fighter project. At present, the Russian Air Force has deployed the Su-57 fighter in the Far East. The F-35B is not only the fighter equipped by the U.S. Marine Corps , but is also purchased by Japan, the United Kingdom, Italy and Singapore. Japan purchased 42 F-35B fighter jets. The scale of the UK's procurement has not been finalized, but it is much smaller than the original 138.
