Recently, air force makes a statement say, because a F-35 produces spontaneous combustion, complete machine produces conflagration subsequently. After igneous situation gets controlling, this F-35 cannot have been used. And this the F-35 of on fire belongs to F-35B, engine of its along with inside cost exceeded 100 million U.S. dollor!
Actually, this is not F-35 produces spontaneous combustion for the first time. 2016, there all was the press of F-35 on fire 2017. The U.S. Army investigates discovery after establishing special board of inquiry, f-35 is met spontaneous combustion, it is the spray pipe temperature because of F-135 engine completely too tall and bring about.
By the F-35 airframe of burn down. From the point of the spontaneous combustion accident of all previous, of U.S. Army one-sided think F-135 just is met too high so because of temperature the viewpoint of on fire may be one's own wishful thinking only. According to author understanding, among the aviation motor that uses in world battleplan, resemble most with F-135 engine, it is the snipe type battleplan that England develops before this, the flying horse motor that snipe type battleplan uses is on thrust, even bigger than F-135. The spray pipe temperature between both, also be to differ very few. But, between the lifetime of snipe type battleplan, delicacy has the temperature because of engine exorbitant and the accident of spontaneous combustion.
Losk Heed. The F-135 temperature that equestrian fourth company announces checks. Can see from inside the graph, when temperature is highest, also do not pass gift 900 much Celsius. With two engine that fluctuate for 900 Celsius, produced huge contrast on function however!
It is after accident happening, many networks army friend puts the view in annihilate on 20 bodies. According to the data of the paper before this, eddy fan the temperature before the turbine of 15 engine, achieved 2000K. If conversion word of, the F-135 with the United States is to differ very few. Namely because of this reason, a lot of army friend think, prospective annihilate the 20 old road that also can be on F-35 probably, produce a lot of accident such as spontaneous combustion. Actually, to this thing, network army friend is blind worried about.
The basis has the evidence of the data, the FGH96 alloy data that at present eddy fan uses 15 times is in some model on the engine firebox that comparing of hold in esteem is 10 one class, had achieved the heat-resisting result of 850 Celsius above. And now, its job temperature also from 850 Celsius, arrived very quickly 1100 Celsius above.
From the point of the check scheme of this document, at present eddy fan the working temperature of 15 engine, won't want than F-135 absolutely low. The senior engineer makes temperature, mean go up in function, can have substantially exceed. A lot of data of engine plant exposure also can prove the dawn before this further, eddy fan the 15 final level that had approached production. Be about to if the engine of put into production has technical trouble, that is very difficult of be born to " card " . So, the author thinks, instantly to annihilate 20 for, the function that how perfects oneself further is more main, outside need not be being paid attention to army the mechanical failure of individual opportunity for combat and be immersed in contradiction!
