Chapter 440

During World War II, when the plane was hit, the pilot had to climb out of the cabin, jump down and pull out his parachute.

However, with the advent of the jet era, this method is very dangerous. When the pilot climbs out, he must move towards the tail when the wind blows. Therefore, after going out, he is directly cut off by the vertical tail of the tail.

At this time, the pilot can't parachute alive by his own ability, so he can only use external force, that is, to eject the pilot. At the beginning, rubber band was used.

Yes, it's a rubber band. It's like a slingshot. It pops the pilot up from the cockpit, and then the pilot parachutes himself.

The rubber band was soon eliminated and became a rocket ejection seat.

The seat under the ass is equipped with a solid rocket. When necessary, it will ignite directly and push people out. This is the modern way for pilots to save themselves.

However, the safety of the ejection seat is different in different ways. In the early MiG-21, the ejection success rate is quite low. Now, the first focus of the improvement of the J-7 is its safety.

At any time, the pilot is the most precious. It is the first priority to save the pilot's life. Now, the improvement of this aircraft is satisfactory to the representatives of date countries present.

"Second, we have improved the engine, with greater thrust and more sufficient power," continued Tu.

Now, the J-8 prototype has been built, and it uses the turbojet-13 engine developed on the basis of turbojet-7. These improvement projects can also be used to improve turbojet-7 and further improve the thrust of turbojet-7.

Power is more or less enough.

These two points are satisfactory to the people of yezao. However, these two points alone are obviously not enough.

"Are there any other improvements?" abid said: "what are the weapons of this fighter? Machine guns? Do you still use the previous aiming method? Missiles? What missiles can be mounted?"

Hearing abid's question, Tu Lao was stunned. Yes, the weapon system is still the same as before.

The moving halo sight has been introduced before. Its principle is quite complex. Without stable training, stable mentality and a set of actions in strict accordance with the procedure, it is impossible to hit the target. This thing has long fallen behind.

On the super-7 fighter, a new hot line aiming is adopted, and the airborne equipment automatically forms a hot line. As long as the hot spot catches the target, it can definitely hit, which is extremely simple.

They have also studied this system, but later sadly found that if they rely on their existing technology to make a breakthrough, it will take at least several years, and it needs the rapid development of electronic technology.

Now, when the yezao people ask, Tu Lao is a little flustered. Recently, he has been engaged in super-7 and wants to get it out. Therefore, there is no great progress in the improvement of the J-7. The cockpit and engine were done well last year, and the air force did not raise any objection and accepted it as usual. However, these foreign guests are not satisfied.

Seeing that Tu Lao couldn't answer for a while, Qin Guan could only answer on his behalf.

"In terms of fire control system, of course, we also need to improve the big knife and axe." Qin Guan walked around the fighter, came to the front of the nose, pointed to the air inlet cone inside and said to the people of yezao: "in the air inlet cone, we can plug in a radar. Although the volume is limited, there is no problem with small air detection. The search distance is expected to be about 30 kilometers."

As mentioned earlier, the air inlet efficiency varies with the speed of the aircraft, so the air inlet adjustment device is required. The air inlet cone can be moved back and forth to adjust.

At the same time, now the air inlet cone is empty. Qin Guan's meaning is obvious. Try every means to find a place. Of course, it should be used here. Insert a radar!

This is not a fluff, because in later generations, the improvement of the J-7 was carried out in this way.

"At the same time, we have installed foreign advanced fire control systems, including machine gun hot line aiming system, head up display system and missile system." Qin Guan continued to talk casually: "After such improvements, we can mount various Western missiles. For example, for the date country, there are a large number of weapons of the chicken country, and the chicken country's short-range air-to-air missiles can be integrated into this J-7 fighter."

When Qin Guan said this, the guests of the date country immediately became more interested.

The performance of the air-to-air missiles developed by the Han country is quite poor. At the same time, if they are introduced in this way, the logistics support of the date palm country will become complex. It would be great if they could mount the missiles of the chicken country!

"However, all these need customers to make choices." Qin Guan said, "so our current J-7 fighters have not made improvements in this regard, but have made plans. As long as there are customers' orders, we can make improvements immediately."

There is nothing on this fighter, but Qin Guan can fool the past so easily, not because we don't equip, but because the customer hasn't decided yet!

We can't improve without customers' orders. You know the reason, because we don't have money in China and the air force has no improvement plan.

Qin Guan is not wrong about this. In history, Han decided to cooperate with Marconi Company in Europe to use their head up display and target computer, that is, 956 head up display HUD and weapon target computer WAC; New anti-jamming ranging radar; The J-7 was refitted with a new atmospheric data computer, a new radar altimeter, a friend or foe identification system, a radio communication security radio station, etc.

As a result, the advance payment was given to others, but the air force didn't want it because there was no money.

As a result, the 6611 research institute decided to go ahead and use these equipment to create a foreign trade aircraft, the J-7 m, which was finally successfully exported to many countries and became a star model of foreign trade.

Old TU was a little nervous. Qin Guan didn't prepare for what he said. Isn't this a lie?

If people in the date country are very interested and actively seek cooperation, but finally find that their own side can't make it, it will screw up.

After all, the development of 6611 Institute also depends on the export of J-7. If this project is screwed up, it will be difficult in the future!

Then he heard that Qin Guan, a layman, was proposing a new plan that they couldn't even think of.

"If there is an order, we can also upgrade the wing, upgrade the current delta wing to double delta wing, and add the leading edge automatic flap. The agility in air combat combat can reach the level of F-16."

Tu Lao is stupid. General manager Qin Guan, you move your mouth up and down. It's easy to say. It's up to the level of F-16. Isn't that ridiculous?
