The contract for the export of Jordan this time is to force Liangshan to fight a tough battle, and we must unify our thinking and fight this tough battle well.

Knowing that some brother factories do not cooperate, the third machine department is also quite anxious, this time Minister Chen led the team, is to unify the mind, now, seeing Tu Lao as the person in charge of the whole project, high-spirited, Minister Chen is finally relieved.

Although Tu Lao is old, his ambition is still the same, and now, the reform and opening up can finally learn from the West, this Marconi company's avionics modification project, no matter how much effort it takes, will definitely complete it!

There is no way back, the project fails, it must be ruined, this is simply walking on the cliff, now, you must go on firmly.

The improvement of the M type should be steadily promoted, while the development of the B type cannot wait.

"We first used our own fighters to improve and complete the J-7B project." Tu Lao said: "The Jordanian side asked us to improve the payload capacity of the fighters, especially to mount the Matra missile, but we do not have this kind of missile at all, and I hope that the Third Aircraft Department can help us solve it." ”

To increase the pylons, to add wing drop tanks, this will bring certain changes, such as the internal fuel pump equipment, such as the use of fuel sequence, and so on.

This can be solved by oneself, but this Matra missile must need the cooperation of the relevant departments at a higher level.

"yes, that's a big problem." Minister Chen said: "This kind of missile, the three aircraft department to find a way, however, missiles are very valuable, even if we introduce a few, it is impossible to use all of them for launch experiments, so let's not use rockets to replace the experiment first?" ”

The biggest problem with launching missiles is the problem of swallowing smoke after launching, and if you use missiles again and again to experiment, it will be quite expensive, and if you use rockets, you can greatly save money.

Although it is said that the prototype of the J-7, the MiG-21, can be hung with missiles, however, this kind of thing is almost not used by the Air Force, and everyone is blank when it comes to playing missiles.

The interface of the weapon or something, you can use live ammunition to study, and when launching, use rockets to simulate, and in the end there is no problem, at most one or two rounds of live ammunition can be fired, and this is enough.

"Minister Chen, your plan is very suitable, and we will start studying it immediately." Tu Lao said.

After sending off the minister of the Third Machinery Department and others, everyone continued to plan the program.

"According to the experience of the J-6 hanging Sidewinder, we can design a similar pylon." Tu Lao said: "The pylons need to be redesigned, and after the suspension, the shape, aerodynamic performance, and weight have changed, and the power supply system uses a static converter, which should be tested in the wind tunnel, the system function test, the strength test, the ground resonance test and the air launch test." We must do this project as soon as possible. ”

The modification must be scientific, all aspects must be carried out in a sound experiment, the lesson of the previous car is in front of us, Shenyang only replaced a hydraulic oil pump, as a result, in the first test run, the entire aircraft was burned.

"Tu Lao, in addition to these experiments, what we should also do is the experiment of engine swallowing." At this moment, Qin Feng spoke.

Launching missiles, what is the most fearful?

For test pilots, it's engine smoke!

"This kind of Matra fighting bomb is said to use butyl hydroxyl composite explosives, the total impulse and specific impulse are high, but the smoke is large, for our turbojet 7B engine, it is easy to cause air stops, we have to find a way to take measures to prevent air stops." Qin Feng continued.

Almost everyone has no experience in launching missiles, but as long as you watch the video, you know that when you launch a missile, the smoke generated by the tail of the missile will envelop the entire fighter, and if the engine sucks in the smoke, it must be stopped in the air.

For a single-engine J-7, it is dangerous to stop in the air.

Now, as soon as Qin Feng said this, everyone also realized the seriousness of this problem, how to solve it?

No one has experience.

Qin Feng's air parking experience is a lot, in the prototype of the flying J-8, air parking is simply commonplace, and at that time, in order to deal with air parking, a set of complex solutions were also designed to deal with it, in fact, it is just a headache plan, and it is necessary to engage in air intake on both sides.

Unconsciously, Qin Feng's thoughts diverged to the J-8, and at this moment, Brother Sun, who had not spoken, spoke: "If we stop in the air, we can just restart, as long as we improve the aircraft and greatly improve the performance of air starting, we can save it." ”

"No, no, if we hit the missile and the engine stops, then the customer will not agree, and we can't always do this when we start a war." Tu Lao immediately denied it.

And after hearing Brother Sun's words, Qin Feng suddenly thought of something and said, "I have a way!" ”

Qin Feng always came up with all kinds of whimsical ideas during the test flight, and now, when he heard Qin Feng say that there was a way, everyone suddenly looked at him again.

"Just now Brother Sun said that if the engine is turned off in the air, restart it, but this will definitely not be accepted by the customer, so let's change it." Qin Feng said: "We designed a set of interlocking ignition devices on the plane, as long as the missile is launched, the moment the missile flies out, our engine will enter the ignition state and keep ignition!" ”

What kind of crooked way is this! Someone immediately thought of it.

In order to avoid the engine from stalling, then in the combustion chamber, keep igniting, so that even if the engine swallows smoke, the engine can still hold on because it continues to inject fuel and with the help of the ignition system.

Hold on for a few seconds and fly over that section of the smoke-swallowing area, then the engine can be slowed down, this is simply a crooked way!

Tu Lao's eyes lit up: "I think this plan is feasible, if the engine does not turn off, it is the best, if the engine is to be turned off, so that the engine can continue to rotate, and our engine, it is also best to change to kerosene to start, so as to avoid gasoline at high altitude gas plugs." ”

Now, there is no way to find a way, if you don't do this, is there a better way to think of it?

The answer is definitely no, and since there is none, then just give it a try!

"This shooting, let Comrade Shen Yongyuan be in charge." Tu Lao said.

"It's designed, I'll fly." Qin Feng said on the side.
