Although the bubble cockpit of the F-15 has a good rear view, the tall ejection seat blocks the rear view. Dick has no idea how serious the engine fire is at the back. He can only see the rear. In the cockpit, the instruction of the engine fire alarm continued to sound.

Today\'s fighter planes are full of fuel and bombs, especially aviation kerosene, and there is a danger of explosion at any time! At this moment, Major Dick was shrouded in the threat of death. He was afraid that the next moment, the entire plane would explode violently, blowing him into a fireball!

So Major Dick hesitated for a second before pulling the ejection handle of his seat.

With the piercing sound of the shrapnel gun piercing the top cover out of the hole, the ejection seat ignited, and Major Dick, who had his legs closed, was successfully ejected from the cockpit!

The initial production F-15 fighters are equipped with McDonnell Douglas ACESII ejection seats, which still have zero-to-zero life-saving capabilities. At zero airspeed and zero altitude, the ejection mechanism starts within 0.3 seconds, the rocket starts within 0.45 seconds, the chair separates after 1.3 seconds, and the parachute opens after 2.3 seconds.

Hearing the whistling wind in his ears, Major Dick was crushed by the huge overload of the ignition of the rocket seat and could not lift his body. Then, his body stopped rising, the seat was separated, his body tightened, and the parachute had opened.

At this time, he opened his eyes, and when he looked down, his face turned pale.

****!

The right engine was still billowing thick smoke, while the left engine was still working normally, pushing the fighter plane and continuing to roll on the runway. However, in just two seconds, a yaw appeared. Under Dick\'s gaze, the unmanned taxiing fighter jet plunged into the apron on one side of the runway!

Four F-15 fighter planes were refueling and hanging bombs there and preparing to take off. When they found this plane rushing over, all the people ran to the side like crazy. Unfortunately, their two legs were completely different. Can\'t escape the fighter jet! In this way, Major Dick\'s fighter jet rushed in here, collided with other fighter jets, and collided with the gas truck of the ground service on the side, and then, a larger and more violent flame appeared!

Even Dick\'s parachute seemed to be pushed by the airflow generated by the explosion and stagnated for a while, and Major Dick seemed to be able to feel the heat of the air wave.

You got yourself into trouble! Before ejecting, at least turn off the engine and stop the fighter! Major Dick closed his eyes.

The fire truck at the base sounded the alarm and quickly went to the place of the explosion, but the soaring flames were not so easy to control!

With his legs on solid ground, and seeing everyone around him nervously rushing to the fire, Major Dick felt a daze in front of him.

Yokota, U.S. Army Command.

"There was an accident at Misawa Base." Lieutenant General Paul listened to the news he just got: "One F-15 engine failed, after the pilot parachuted to escape, the fighter plane hit the tarmac and crashed four F-15 fighter planes. As a result, the refueling truck exploded, and the Misawa Base has now put out the fire, and it will take two hours to restore the dispatch capability."

As a forward base, ready to support the air combat in Hokkaido, the Misawa Base deploys the most important F-15 fighter jets of the US military! Now, the F-15 fighter at Misawa Base has such an accident!

Lieutenant General Paul\'s face was very serious, the chain fell at a critical moment, and some people must be held accountable!

"Also, the technical experts of McDonnell Douglas conducted a failure analysis on the spot and believed that the F-15 fighter jet that first caught fire due to the engine failure was caused by the breakage of the engine compressor blades. I hope we will ground all F-15 fighter jets. , After the comprehensive inspection is completed, it is confirmed that it is safe, and then the go-around."

"What?" Lieutenant General Paul stood up: "Our F-15 fighter plane can go back to flight after all engines have been fully tested? This request from McDonnell Douglas is at the right time! Immediately connect me to McDonnell Douglas. phone!"

Now, if you want to seize air supremacy over Hokkaido, you must rely on a powerful third-generation aircraft like the F-15! Only the F-15 can have enough technical advantages! Lieutenant General Paul put all his hopes on the F-15. Throughout the island country, the F-15 equipped by the US military and the island country\'s Air Self-Defense Force has reached hundreds! In the narrow airspace of Hokkaido, it is enough to seize air supremacy without the need for F-4 to play.

But now, the battle is about to start, and McDonnell Douglas says it will ground the F-15? Lieutenant General Paul really wanted to take out his pistol at this time, pointed at the head of the head of McDonnell Douglas, and asked him if he was serving the KGB!

"Hey, I\'m Lieutenant General Paul, what\'s wrong with the grounding of our F-15 fighter jets?" Lieutenant General Paul pressed the anger in his heart and asked the other side of the phone.

"Report General, I\'m HP\'s engine engineer Smith." The words on the other end of the phone were a bit blunt: "The engine that just ran out of control was caused by the breakage of the compressor blades. This is not an exception. We suspect that this batch of engines are all I have the same problem and must be tested one by one to be sure. Now we are dismantling another F-15 engine, and we have found that there are cracks on the blades of the compressor. In the fierce air confrontation, the cracks in the blades are easy to expand. and breakage, in this way, is not good for our pilots."

(Pratt & Whitney, PW, not HP, HP, Pratt & Whitney makes engines~www.novelhall.com~ HP makes PCs, and it has nothing to do with it.)

Another F-15 engine, after disassembly, also found cracks on the compressor blades! This shows that this is definitely not an exception, it is a sign of a serious accident!

F100, an engine with a thrust-to-weight ratio of 8 manufactured by Pratt & Whitney in the United States, is astonishingly advanced. In later generations, Huaxia has developed turbofans for more than ten years, and the technical indicators are still not as good as the F100. You must know that the F100 was in the 1970s. Just put it into use! Moreover, the total development time is less than four years!

The designers considered the high-performance requirements of the engine that users put great emphasis on: large thrust, high thrust ratio, and adopted a large number of advanced technologies at that time, such as the typical "2 high and 1 low" thermal cycle parameters, that is, high boost ratio, high turbo Front temperature, low bypass ratio, a large number of new materials, new processes and new structures are used. For example, the amount of titanium alloy materials has reached more than 25% of the total weight of the engine; the first use of IN100 powder superalloy to manufacture large-diameter turbine disks, compressor disks, etc. 11 parts, turbine blades made of PWA1422 directionally solidified superalloy; advanced processes such as precision casting, hot isostatic pressing (HIP), electron beam welding (EBW) are used in the processing technology...

However, the hasty launch of this engine also has disadvantages. This disadvantage is reliability! (To be continued.) Enable new URL
