Bright Sword Military System

In fact, many people can understand Wang Xuexin's statement that he does not use missiles.

Because the previous fighters, whether they were "J-1" or "Wildcat", the reason why they used missiles was to use their long-range advantages to make up for the lack of fighter performance and pilot training.

Now that the "J-2" has such speed, it can already form an absolute advantage over the Japanese fighters. Why do we still need to use missiles?

On the other hand, the development of air-to-air missiles at this time was not yet mature, and it required the pilot to continuously control the missile to track the target after launch... This is no problem for the slower "Wildcat" or "J-1", but if it is used in The problem with the "J-900" with a speed of more than 2 kilometers is huge: the pilot does not have that much reaction time, and the fighter plane is likely to surpass the missile and approach the target first.

What will be the result of the missile explosion?
However, people who would think so did not expect another question, which was raised by He Zhimin.

"Captain!" He Zhimin frowned and said, "If we don't use missiles, how can we use machine guns? I'm afraid that's inappropriate!"

"What's inappropriate?" Chen Jiefeng asked: "We should use machine guns and cannons. We are invincible because of our speed!"

"It's indeed inappropriate!" Wang Xuexin nodded, secretly saying that He Zhimin is indeed a math expert and is very detailed in calculations.

"Comrades!" In order to make it easier for everyone to understand, Wang Xuexin explained while drawing on the blackboard: "The range of the machine guns currently used by our army is generally about 300 meters. 300 meters is no problem for low-speed fighters, such as the J-Fighter 1'Tail-biting' zero battle', the speed difference is only more than 100 kilometers per hour, and the distance of 300 meters takes about ten seconds. In other words, there is about 10 seconds of reaction time from the target entering the pilot's range to the pilot taking aim and shooting! But if the J-2 '..."

This researcher understood everything when it came to it.

The "J-2" is so fast, easily reaching a speed of 900 kilometers per hour.

There is a gap of 900 kilometers per hour between the speed of 530 kilometers per hour and the speed of 370 kilometers per hour of the "Zero War".

If we use this speed to carry out a tail-biting pursuit of the "Zero War", it will only take about 3 seconds from the time the target enters the range to the time the two aircraft collide.

In 3 seconds, does the pilot have time to complete a series of actions such as aiming, shooting, climbing and dodging?
I'm afraid I can't aim at all and will always collide with the enemy plane!

Or the "J-2" slows down to adapt to the enemy aircraft's tail biting, but doing so will cause the "J-2" to lose its speed advantage, and the high speed of 900 kilometers will not make much sense in actual combat.

Then Su Xin felt strange: "Captain, we don't need missiles and can't use machine guns, so how are we going to fight this battle?"

Of course Wang Xuexin had considered this issue. He nodded to He Zhimin and said, "I have imported a batch of new aircraft cannons from Mao Xiong. Its range reaches 2000 meters. It allows our army to operate at ranges from 400 meters to 1200 meters." Attack the target within range!"

The researchers breathed a sigh of relief and secretly thought that there was such a thing.

This aircraft gun is actually the HC-23km aircraft gun newly developed by Mao Xiong. It was developed by Mao Xiong and used on the IL-10 attack aircraft. It will also be used on the "Mig-15" in the future. It can be said to be similar to the "J-2" "It's a perfect match.

Wang Xuexin bought 200 of these from Mao Xiong a month ago, and each door is equipped with [-] rounds of ammunition (it can carry [-] rounds of ammunition in a single battle).

Compared with the Schwack aircraft cannon previously used on the "La 23", the HC-5km aircraft gun has a significant improvement in accuracy and a weight reduction.

Furry bear gadgets have always been rough, bulky, and poor in accuracy, so they have a lot of room for improvement in this regard.

In the past, Mao Xiong had no time to care about these when his equipment was tight. Now that the battle is getting smoother and victory is in sight, he has begun to consider improving the performance of his equipment.

Both of these aspects have been very successful, and the aircraft cannon with a range of only 1000 meters has been directly increased to 2000 meters.

In terms of weight reduction, not only the weight of the gun body has been reduced by 3 kilograms, but the ammunition chain and shells have also been redesigned to only half the original weight.Every bit of weight on a fighter plane is a valuable resource.

This allows it to be used on high-speed fighter aircraft and may even become standard equipment for high-speed fighter aircraft for a long time in the future.

Mao Xiong thought that Wang Xuexin bought this aircraft cannon to upgrade the "La 5". In addition, it was not high-tech, so he agreed without thinking.

If Mao Xiong knew that the cannon he sold to the Eighth Route Army was installed on the "J-2" and became the most powerful fighter at that time, he would probably hesitate.

He Zhimin calculated in his mind that this aircraft gun fully meets the requirements of the "J-2":

2000米射程意味着飞行员有20秒左右的战斗时间：2000米距离预先瞄准，在1200米距离进入攻击范围射击，到400米左右还有3到4秒时间躲避。

Thinking of this, He Zhimin nodded and said: "Captain, that's no problem! I think this fighter jet will be tested for a few more days. If there are no other major defects, it can enter mass production!"

Wang Xuexin shook his head slightly, and then looked at Su Xin.

Su Xin looked a little confused and asked awkwardly: "Tuan, leader... do you have any questions?"

"Pilot!" Wang Xuexin asked: "Can you find the pilot?"

"Pilot..." Su Xin asked doubtfully, "Don't we have a pilot?"

Wang Xuexin shook his head again, then turned his gaze to the researcher and asked: "Comrades should know about the problem of pilot overload, right?"

The researchers nodded.

Then several people immediately understood why Wang Xuexin mentioned pilots!

Overload is also a thing in propeller fighters, but because the propeller engine is not very powerful, even if it occurs, it is mostly within the range that the pilot's body can bear.

But subsonic fighters like the "J-2" are different. Its overload can reach plus or minus 7 G. Pilots who have not received special overload training are prone to a series of problems such as gray vision, black vision and even coma.

Therefore, not all pilots who can fly propeller fighters can fly the J-2.

Even the threshold for pilots' physical examinations must be significantly raised... Pilots with injuries and scars cannot fly this fighter in principle. Their wounds are likely to rupture under heavy overload or high altitude.

This may seem like a small thing, but in reality it’s a big problem.

In this era of war and chaos, finding a few people who have no scars on their bodies and meet the qualifications of pilots is almost like looking for a needle in a haystack.

When Wang Xuexin mentioned these issues at the meeting, the researchers were instantly stunned... They had only thought about the overall improvement of fighter aircraft performance, but they did not expect that the improvement of fighter aircraft performance would also place higher requirements on pilots.

The biggest problem is not the fighter plane itself, but the pilots flying the fighter planes.

Problems with fighter planes can still be modified, but if it’s a problem with people...
