In the movie, it can be seen that the air combat is very easy, ignition, launch, and go out, in fact, of course, this is not the case, the launch of the missile, is a rather tedious step.

Take the current short-range missile as an example, first of all, we must turn on the power supply of the missile, start the spinning top of the missile, if it is a laser gyroscope, the time may be shorter, and then lift the fire control safety of the missile, and at the same time, begin to cool the warhead of the missile, only with liquid nitrogen for cooling, in order to let the seeker see farther, and then, the on-board fire control system begins to input various parameters of the target aircraft, so that the missile seeker rotates, begins to lock on to the target, and when the lock is successful, it can be ignited and launched.

There is no room for error in every step, and at the same time, there is also time.

This includes the preparation time of the seeker, the time from the ignition of the missile engine to the actual ejection, and the time it takes for the seeker to capture the target.

The preparation time of the seeker is first of all to activate the gyroscope on the projectile, which basically takes 2-3 seconds; Then it is necessary to reduce the temperature of the infrared guidance device of the seeker, which will take another 2-3 seconds. However, experienced pilots tend to activate the seeker before engagement, so this leaves the seeker with the time it takes to capture the target and the time from engine ignition to ejection, which is about 1-2 seconds. In this way, the preparation time of the missile may be about 2-4 seconds.

Of course, this is just a launch, and before launching, various maneuvers are required to keep up with enemy aircraft and get a chance to fire.

As for medium-range air-to-air missiles, this is even more troublesome, before launching, the pilot or weapon operator needs to manually turn on the radar and select the scanning mode, after discovering the target, it is necessary to maintain a tracking state so that the airborne radar can determine the flight parameters of the enemy aircraft, there are many parameters, such as altitude, speed, distance, direction angle and angle of attack, etc., and then manually input the flight parameters of the enemy aircraft and calculate the attack trajectory. Then turn on the power of the missile, release the missile fire control safe, lock it, and then launch again.

Such a cumbersome process can not even be handled by one pilot, so the kind of heavy interception combat aircraft often requires two people, and the pilot behind is specially used to operate the fire control system.

Of course, the current launch is much simpler, it is just that you need to shoot the missile out, and try it first.

On the screen, you can see clearly, the camera in the cockpit clearly captured the scene of the moment of the missile launch on the wing, and it can be seen that when the missile was launched, a puff of white smoke quickly filled the entire field of vision.

That must be exciting, right? Qin Feng secretly thought in his heart, but at this moment, a voice came from the radio: "032 report, the engine is stopped." ”

Engine stop? Qin Feng hurriedly looked at the screen on the other side, and sure enough, the data showing the engine were all red, and the engine speed had been reset to zero.

What is this operation? How can the engine stop? What does this have to do with the engine?

"Start in the air immediately." The commander commanded.

With the continuous progress of test flights, everyone is psychologically prepared for the air parking of the J-7, and at the same time, its air start is also very easy.

Needless to say, the J-7 is a twin-engine like the J-8, and the two often stop together, isn't it still successful in the air?

Sure enough, soon, the engine's data was restored.

A rumbling sound sounded in the distance, and the J-7 fighter flew back.

When he landed, Lao Zhao came out of the cockpit and immediately said: "Evil Gate, it's really evil, I don't know what's going on, as soon as it is launched, the engine will turn off." ”

"Are there any other phenomena before the engine is turned off?" Richard asked.

He asked, looking at the wings, as if he had already thought of something.

"Before the ignition was turned off, the plane flipped on its side." Lao Zhao said.

The plane flipped on its side? Richard frowned: "Or, try another shot?" ”

If this shot is successful, then the experiment will be over, and we will wait for the target aircraft to be finalized, but now, just a launch process, this kind of problem has arisen, and we can't be stingy with the preciousness of missiles, and then try to fight.

After all, if you can't fight, then what's the use of missiles?

"Try someone else and find someone more experienced." Richard said.

More experienced? Lao Zhao's experience is the richest, General Lin frowned, and named another test pilot to go up.

Everyone looked nervously at the command and control room, and when the missile was launched, their throats and eyes were raised to their mouths, but they still heard the same report.

Engine Stop!

After hanging the missiles, as soon as there is a dozen missiles, the plane rolls over and stops!

This is simply evil.

"Why don't we try to change the position of the pylon?"

On the pylons, there are auxiliary fuel tanks and missiles, so try to replace the position of the auxiliary fuel tank with missiles?

This day was the most memorable for everyone, and in the afternoon, the three test pilots had already gone up twice each, exhausted all methods, fired six missiles, and all of them had the problem of engine stopping.

The symptoms are exactly the same.

Richard watched the last pilot come down dejectedly and said, "Your Jian-7 can't fight this kind of missile." ”

Hearing his conclusion, everyone's faces changed, even General Lin became ugly, this project was almost promoted by him, but now, if this missile can't be hung on the Jian-7, it will be a complete waste.

"What's going on?" General Lin said: "We can fight other missiles, there is no problem." ”

"Because the launch method of the No. 8 bomb is different from your previous air-to-air missile, it used to be a drop-off type, and the current missile is a total impulse launch, and the aircraft was subjected to too much disturbance force when launched, reaching 7.2 tons, and the thrust of your J-7 engine is only 6 tons. Therefore, after hitting out, the thrust is too great, so the plane is pushed to the side, and the pilot immediately controls the plane to level after the rollover, and then the feather smoke of the missile engine just stops the air intake mask of the aircraft, and the plane inhales the feather smoke and causes the engine to stop. ”

Richard's analysis is completely accurate.

And so the conclusion comes out.

Why didn't they show up on their plane? Because their planes are very heavy, F-15, F-16, are much heavier than J-7, J-7 is too light, this kind of small plane, can't hit this kind of missile.

Change the launch method? That's impossible, and the Israeli experts won't change it, they are only responsible for giving it to the kits, not changing the missiles.

Now, it was already afternoon, and everyone had gone from elation to despondency, and the experiment was about to go on.
