At that time, only endurance tests were carried out, and it was proved that the engine was capable of sufficient flight hours. Pen, fun, pavilion www. biquge。 However, the designers simply did not anticipate how violent the pilots at the front line would be.

Instantaneous increase or decrease of throttle, all kinds of complex maneuvers... No fighter pilot would fly a fighter jet as a civil aircraft! And the current F100, although it is better than the TF-30 of the Tomcat fighter, will not have frequent surge, but the compressor stall has always been bothering the pilots of the F-15, although it is very simple to change out, twin engines, one stall, the other can work normally, flatten the aircraft, let the turbine cool down, restart in the air, and change it.

However, in the heat of air combat, stalling means death, and the opponent will not give you a chance to change out! You fly flat for a few minutes, and that's to be a target!

Just a stall has already put a heavy burden on the pilots on the front line, and now, there is one more, the compressor blades are broken!

The engine stalls, that is, the engine stalls, and the compressor blades are broken, it is not simple! The blades rotate at high speed, and after breaking, the speed of centrifugal flight has already exceeded that of bullets! Hit the blades in the back, hit the combustion chamber, break the shell of the engine, break all kinds of pipes... The F-15 engine caught fire just now because the blades broke and broke the hydraulic oil pipeline, causing the hydraulic oil to catch fire!

If Major Dick was brave enough at that time to control the plane to stop, after all, it was not the fuel that caught fire, he still had a chance, but unfortunately, the fear of death made Major Dick make a big mistake. What's more, the regulations of the United States are to protect people first, and then planes!

During the test run, the F100 engine had a crack in the blades of the compressor, and then, in the official production, through strict technology, the standard of material selection was higher, and Pratt & Whitney once thought that this problem had been overcome!

However, since the F-15 engine was equipped with the Far Eastern Forces, it has been in high-intensity flight training, after all, they are facing the war head-on, and frequent use has caused this problem to occur again during the life of the F100 engine!

"Because the performance indicators of our F100 have made a qualitative leap compared with the previous generation, the fighter has strong maneuverability and a wide flight envelope. It is precisely because of the high mobility characteristics of the F-15 that it is required to be able to quickly push and pull the throttle lever back and forth in use, which causes the engine speed and temperature to change sharply, resulting in the main components being subjected to variable stress cycles. On the other side of the phone, Pratt & Whitney's engineer was still chattering: "When the Air Force made the request, it did not specify a reliability test. Our company noticed this problem as early as 70 years, but unfortunately, it was delayed by the Air Force. We apologize for what is happening, and hope that the general will give the White House a job and give us a grant to conduct a durability study. ”

"Get out! Go ahead! Lieutenant General Paul couldn't help but be furious on the other side of the phone, he was already completely angry! Until now, Pratt & Whitney still thinks about their little selfish interests, and does not care about the prestige and safety of the US Air Force at all! This group of blood-eating capitalists!

Lieutenant General Paul was completely speechless, the family is dominant! Lieutenant General Paul has heard about some things in China.

When the engine is finalized, it is mainly to assess the high temperature working ability of the engine in the longest steady-state time, rather than the working ability under multiple cycles. As a result, it has led to various failures in the actual operation of the present.

The U.S. Air Force is like an ant on a hot pot, in fact, not now, last year, or even the year before last, the troops equipped with F-15 fighters realized the problem of reliability and asked Pratt & Whitney to rectify, but Pratt & Whitney's answer made people angry!

"We have met the requirements of the original type specifications, and now our company is responsible for helping to maintain the engines, which are quite expensive to maintain, and now, our company can help the military solve these problems, but the cost needs to be fully provided by the government!"

When the fighter was finalized and the troops were equipped for the first time, the maintenance work was first done by the company's people, and slowly transitioned to the ground support of the Air Force.

This made the air force generals, who were already very angry, feel the arrogance and irresponsibility of Pratt & Whitney, and of course they would not agree to Pratt & Whitney's request.

However, when the Air Force looked back, it turned out that they simply did not have a spare engine to choose from! And their third-generation aircraft, F-15, and the F-16 that will be put into service will only be able to choose F100 engines!

Pratt & Whitney is well aware of this, and the Air Force has no choice! Just played a scoundrel, just one word, drag, if your Air Force doesn't give money, it will be impossible to improve! The Air Force must give in!

In history, it dragged on until 79 years, the Air Force was cold, and Pratt & Whitney deliberately reduced production capacity under the pretext that there was a strike on the two main subcontractors of the engine, so that the engine was in short supply, so that the new F-15 did not have an engine when it was delivered! Trying to force the Air Force to back down in this way.

It's a pity that the Air Force is already cold, and the power of the third-generation aircraft is dominated by Pratt & Whitney, which is definitely not a good thing! The deflated Air Force began to support General Dynamics in the development of engines.

At this time, Pratt & Whitney suddenly changed its attitude, and the high amount of research and development funds was not needed, but it formulated various preferential policies, the premise was to squeeze out the general motors, at this time, the air force was unmoved, and insisted on letting the f101 engine of the general motors develop into the f110 engine, which became another driving force for the third-generation aircraft.

Without competition, there is no development! In later generations, the United States has always adhered to the competition mechanism in equipment, especially the Air Force, which has learned a lesson from here.

And now, other engines have not yet appeared, Pratt & Whitney is in a state of arrogant asking for a sky-high price, and now, the engine has a serious failure, and they are still making demands for the interests of their company!

It's good enough that I didn't send you to a court-martial! Lieutenant General Paul, who put down the phone, his face was gloomy and terrifying, his fists were clenched tightly, and his muscles were bursting out, looking like this, he could run to the Misawa base at any time to beat those guys who were inclusive of Pratt & Whitney!

"Order, grounding all F-15 fleets, check the engines." Slowly loosening his fist, Lieutenant General Paul still gave this order, he knew that making such a choice would mean giving up Hokkaido, but if the fighter plane was faulty, it would definitely not be able to take off, fly over, give the Soviets experience, and increase the results of the battle?
