A total of 22 B2 stealth strategic bombers have been produced, but there have been at least four major crashes since they entered service. However, all of these 4 major accidents were not planted headlong during high-altitude flight, but were all during take-off and landing, and inexplicably there was a loss of control! Either slam on the runway, or rush out of the runway and slam into it. Post-mortem investigations often attribute the cause to the fact that cold water from the outside flushing the airframe entered the hidden airspeed tube, causing the airspeed tube to send serious wrong altitude and speed data to the flight computer, resulting in a system crash. In fact, many crashes are a prescription for medicine, and it is difficult to say that it is all a problem of water ingress into the airspeed tube. It is more likely that Wolf Mountain has been emphasizing: the superpower itself has not mastered all the aerodynamic and flight control essentials of the 170-ton stealth large flying wing, especially during take-off and landing, which is very close to the ground, and the huge flying wing and the ground instantly produce an instantaneous ground aerodynamic effect that does not exist under normal circumstances.
As a result, multiple flight control computers on B2 went down directly, resulting in a complete loss of control. This is almost an unsolvable bug. Until the B21, which has basically the same aerodynamic shape, it can only be comprehensively reduced in weight and size to avoid the unpredictable and powerful ground effect problem. However, if there is an accident in the ground effect state, it means that the crash height of B2 is only one or twenty meters at most. So in the past, the 3 that crashed like this, in addition to the violent burning explosion after 2 crashed to the ground, and finally burned to the point that there was no need to repair it, the other B2, which was slightly injured, actually took 5 years and worked hard to finally repair and fly into the sky again. In this way, the entire fleet of B2 still retains an integer of 20 aircraft. But not long ago, another B2 rushed out of the runway during landing. It is said that this accident was the least injured compared to the previous three times. just
damaged landing gear; There are only some abrasions on the lower part of the body itself, which vary from light to severe. It would have been much less difficult to repair than the one that had been repaired in the past. But I didn't expect that after more than a year of tossing, the superpower Air Force finally announced that it would completely abandon this B2 and no longer continue the repair project, but disassemble and scrap it! As a result, the original number of 22 B2 aircraft is equivalent to the complete destruction of 3 aircraft and only 19 aircraft remain. So why did you give up when you were injured minorly? The US Air Force itself explained that the budget was insufficient and the repair technology was too difficult. This is obviously not telling the truth to the outside world. With the superpower's annual military expenditure of nearly 900 billion, is there a lack of these two dates that specialize in repairing B2? No matter how difficult it is to repair, it can surpass the previous one; Can it be repaired in the end? The reality is likely to lie in the fact that the echelon of workers who produced B2 was seriously overage, and most of the experienced masters were either retired for many years or no longer there. And the newly recruited maintenance team,
Basically, they are two knives with low quality, and you have to highlight the ZZ correctly! The leader of the maintenance team must be painted in a certain depth, and the deputy leader must be of a special group. The 4-hour construction period a day, of which 3 and a half hours are used for special relaxation, and whoever dares to give an opinion will immediately throw his face. Each new screw starts at six digits, and no one is allowed to rush for 10 years! In this way, the US Air Force did not take the initiative to abandon the treatment, and still kept it for the New Year?
