Chapter 268: Moody Engine
Turn on the afterburner, climb upward, and release the decoy bomb at the same time, then press the lever and turn off the afterburner, allowing the fighter to dive down quickly, and the positive and negative overloads in a series of channels make Yuji Ikeda vomit.

Fortunately, the missile was first attracted by the afterburner heat wave, and then climbed upward, consuming precious energy in the ascent, and after Yuji Ikeda turned off the afterburner and dive, the missile caught up with the heat flare that attracted it even more.
Yaga, the missiles of the Soviets, what an abomination! Yuji Ikeda changed out of the dive and couldn't help but want to curse, but unfortunately, before he could say it, he heard an anxious voice in the headphones, 421, attention, six o'clock direction!
Six o'clock direction, own tail direction! The Soviets actually bitten it? When Yuji Ikeda heard the sound of the warning, he immediately pushed his lever to the far right, and at the same time stepped on the rudder on the right.
Want to bite yourself and launch a missile from behind? There are no doors! Yuji Ikeda adopted a simple tactic and turned sideways! Compare the hovering ability to see who is better!
Plaster flag, what about tricks? Kovacevic had just seen that his head-on missile was not working, and the opponent dived down to get rid of the missile, so he followed and pushed the nose and dived downward. From a height of 8,000 meters, he followed to 3,000 meters, and then the other party leveled and followed himself. As soon as he wanted to launch a missile, the other side began to turn.
Follow along! Just when the dive was made, the wing was swept back to the end, and now, as Kovacevich began to turn sideways, the wing automatically rose forward, and the guys from the Mikoyan Design Bureau, really well done! The wing is like knowing what's going on in the pilot's head! compared to manual control. Kovacevic is quite content with the current control.
See what other tricks you have up your sleeve!
Left, right. Flying in a straight line for no more than five seconds, Ikeda doesn't create any lock-up chances. However, the Soviets in the back could not get rid of it.
What to do? Ikeda gritted his teeth and flicked a switch on the side of his right, pushing the throttle to the smallest position with his left hand.
Damn it, cunning islanders! Kovacevic looked at the F-15 fighter in front of him, and suddenly braked sharply in the air, and a big guy rose on the opponent's back!
F-15 at the time of design. The skin on the back is designed as a large airbrake that can be opened at any speed without causing pitch changes. This 2.93-square-meter speed brake is unique to F-15 fighters, and generally speaking, it is used when landing, eliminating the need for parachutes.
The rear of Soviet aircraft had a high dorsal fin, so it was impossible to use the same design, and it came to later generations. The beautiful Su-27 fighter designed by the Sukhoi Design Bureau has almost the same equipment.
Now, this airbrake is still a novelty, and the airbrake plus the throttle is released. The speed of the F-15 dropped sharply, and behind the MiG-23. And so suddenly rushed to the front, although the MiG-23 was also quite agile. But this sudden braking in the air can't be done. At this speed, even if Kovacevic opened the parachute, it was instantly blown by the air current.
In general, no pilot in air combat will operate like this, the most important thing in air combat is energy! With energy, we can forge victory in air battles! If you lose speed, you lose everything. For example, in the eyes of countless military fans in later generations, the god-like Pugachev Cobra maneuver of the Su-27 was just a showpiece of an air show performance, and it had no actual combat significance at all.
As now, although Yuji Ikeda's sudden slowdown caused the MiG-23 behind him to rush to the front, at the same time, the MiG-23 that rushed out was moving away quickly.
Of course, Yuji Ikeda knows that energy is everything, and he is doing it now only because he has full confidence in his fighter, and the two F100 engines behind him have a single afterburner thrust of more than 110 kN, and in the case of a 13-ton empty aircraft, the thrust-to-weight ratio of the whole aircraft has reached 1.7! Of all the third-generation aircraft, the F-15 has the highest thrust-to-weight ratio and is unbeatable! Even the F-22 of later generations cannot be compared.
Now, the auxiliary fuel tank has long been thrown away, part of the fuel in the aircraft has been burned, and the thrust-to-weight ratio of the F-15 is also about 1.4, and it is not a piece of cake to pursue the MiG-23 in front!
With this in mind, Yuji Ikeda turned on the afterburner and opened the throttle wide, expecting the familiar feeling of pushing back.
"Boom!" A voice came from behind, and then, a voice alarm came from the cockpit: "Left engine failure, left engine failure!" ”
Afterburner, in fact, is in the rear section of the engine in an afterburner, there is a circle of fuel injectors and spark plugs, fuel injectors inject aviation fuel, spark plugs ignite fuel, produce more thrust, this way, no more oxygen participation, is completely fuel injection, natural fuel consumption rate surge.
Now, with Yuji Ikeda's operation, the fuel injector began to inject fuel into the combustion chamber, but it did not burn immediately after the injection, and the afterburner ignition failed!
In the afterburner, a large amount of fuel is increasing dramatically, and at the same time, in the front core machine, thousands of degrees of high-temperature gas, rushed to the back combustion chamber with lightning speed.
"Boom!" This sound is a small-scale explosion in the afterburner combustion chamber, with the explosion, a large amount of high-temperature and high-pressure gas is rapidly formed, not only sprayed backwards, overpressure airflow, but also reversed to the front!
This air flow flows from the outer duct and rushes to the front fan, and the airfoil-shaped fan blades stall first! The stall of the fan caused the first stages of the compressor to stall!
Advanced technology requires risk. The F100 engine in the United States is very advanced in technology and is the first engine in the world to achieve a thrust-to-weight ratio of 8, but reliability has always been a big problem!
After equipping the troops, the F100 engine is prone to stalling, with the same symptoms as the TF30 of the F-14! And this inherent stubborn disease of the F100 engine is still in Pratt? In the history of the Whitney Company, the F-15 fleet once had a large area of nests in 79 years because of these problems, and won the reputation of the queen of the hangar. The US Air Force was even forced to receive the F-79A without engines, put them into storage and wait for the engines, beginning at the end of the year.
The early F100 engines were moody! The plan given by Pratt & Whitney is to operate gently, especially not to switch the afterburner frequently! And in the actual fast-changing air combat, this is simply impossible.
Yuji Ikeda knew that he was in big trouble. (To be continued.) )
