On December 7th, Japan's self-developed X-2 heart technology verification machine carried out the fourth test flight, and this test flight broke out some clear photos of the X-2 aircraft belly, showing the details of the belly, and also let the previous The details of the blurring in the photo are shown. For example, the position of the nose gear was previously obscured by Japan and seemed to be worried about leaking. However, in the test flight, the nose gear was very clearly displayed. With the front wheel design of the landing gear, the sawtooth structure of the nose gear hatch seems to It is invisible. The boundary layer structure of the air inlet and the DSI air inlet of the F35 are quite different, which is closer to the F22 fighter. There is a strip-like device between the belly engines, suspected to land the tail hook. The shape of the tail is similar to the shape of the tail hook. The specific position of the device can be clearly displayed from other belly maps. The specific position of the device can be clearly displayed from other belly maps. So what is the use of this suspected hook device? At present, two speculations can be made. First, as a technical verification machine, the landing technology may be verified, but Japan does not seem to have this condition to verify, in addition, if It is a carrier-based aircraft, at least it should be the landing gear of the front two-wheel, which is almost the mode adopted by all carrier aircraft, and the X-2 is the front single wheel. It seems that this possibility is not verified as a carrier aircraft technology. Big. There is also the possibility that the device is an emergency landing device for the aircraft. This device is equipped on many American fighters for emergency situations on land landings. When the aircraft cannot stop, the tail hook is used to force the aircraft to stop. Japanese equipped F15J fighters also have tail hooks A ground-based F-16 fighter jet of the 138th Fighter Wing of the US Oklahoma National Guard tested the landing hook blocking system at Tulsa International Airport.
