Zuo Lengchan, the military and the bigwigs of the research institute, after a day of urgent consultation, finally came up with a more reliable cooperation plan.

The supply of special materials is given priority to Yitie Group. They bought this thing at five times the price of gold, and they also paid a certain amount of cash compensation per kilogram as before.

But as soon as this proposal was proposed, it was directly rejected by Xiao Chu.

The reason is that if you sacrifice to get the 10,000-year-old cold iron in the future, the price will be higher and higher, and the price per thousand catties will rise by ten percent, and the mutton fat white jade used for transmission is not so easy to do, and the little money you compensate for is not enough to buy jade.

If you want to make a deal, show sincerity. Foreign organizations are asking for double the price, and he is still hesitating whether to sell or not.

In fact, according to Xiao Chu, he prefers gold, because there is extra gold, and he can also try to sacrifice other things. Buddha gold is much more valuable than 10,000-year-old cold iron. It doesn't take much, a whole kilogram of Buddha gold is enough for a whole hundred kilograms of gold.

This is logical. The whole Zuo Lengchan and the others had itchy teeth for a while, but there was no way, the one who should be traded had to be traded, after all, this thing was the only one.

According to their tests, an engine can only last for about 1,000 hours of high temperature if it adds about 20 kilograms of alloy materials made of this special material.

Fortunately, the service life of other parts of the engine is more than 1,000 hours. All aspects of performance need to be improved.

And this thing seems to be very powerful, but it can't be added too much, once too much is added, it will make other metal parts in the engine fragile because of its own low-temperature properties.

And the aircraft equipped with this kind of engine seems to be able to take off normally only with the help of external force ejection, otherwise it will accelerate the take-off directly, and it is easy to deform or even crack the engine with a large gap between cold and heat. Otherwise, you have to spend a lot of fuel to warm up the engine, starting from a temperature of a few hundred degrees.

Basically, it is more time-consuming, laborious and costly to serve this engine than other aero engines.

Let's put it this way, other aero engines are one-year-old children, and this kind of engine is basically a newborn baby, or a high-risk baby living in an incubator, and it is difficult to serve.

However, compared to the speed that can propel the fighter to Mach 4 after opening the afterburner, this thing is also against the sky. At speeds above four times the speed of sound, hehe, almost all anti-aircraft missiles can't catch up, let alone shoot down. Even, without afterburner, it can maintain a speed of Mach 2 cruise. Proper supersonic cruise, maybe many people don't understand what it means, there used to be a supersonic cruise, but that is after the afterburner consumes a lot of fuel to do, the same fuel can maintain three times the speed of sound high-speed cruise, which is not a little bit of the improvement of aircraft performance, more exaggerated or the afterburner after the four-time sonic raid.

This situation is the same as the suppressive reconnaissance of us by hypersonic reconnaissance planes, and you can't resist at all.

Because your fighter plane can only rise to less than 10,000 meters, but people fly directly at an altitude of 20,000 meters, and the cannon fighters on your fighter plane can't hit people at all.

It is reliable to let the missile fly 10 kilometers, but to let the airborne missile climb 10 kilometers is basically a joke.

The biggest feature of this engine is the low-temperature performance, which can adapt to the low-temperature performance of this engine, so it is not a problem to climb to the ceiling of 30,000 meters.

Now most fighters can't reach the ceiling of 20,000 meters, let alone 30,000 meters. Even if a large anti-aircraft missile is used to intercept it, it is basically impossible for all the anti-aircraft missiles in service to penetrate the defense at a speed of Mach 4 in the face of a fighter plane above an altitude of 30,000 meters.

Therefore, once equipped with this kind of engine and performing special tasks, this kind of aircraft is almost invincible, just like the original old rice, a few years ahead of you, so that your plane can't reach and can't hit. If it weren't for the old Maozi to come up with an airport guard urgently, it is estimated that the old Mi's fighters would be able to dominate the sky of the Mao Bear.

In the past, when it reached the double three standard, it paid a lot of weakening of other attributes, reducing the bomb load, increasing the fuel reserve, and even the combat radius was smaller.

But after the advent of this engine, I am afraid that all this will change qualitatively.

Everyone knows what the consequences will be if such an important raw material is cut off, at least after saving a few tons. Therefore, the military can only pinch its nose and admit Xiao Chu's temporary (shameless) price increase. Besides, what people say is also reasonable, and you can't let people work in vain.

Looking at the 20 million that arrived, and then looking at the batch of superb jade that had just been delivered, Xiao Chu couldn't help but be shocked by the country's heritage.

The texture of this batch of jade is so good, he has never seen it in the antique street before, even if it is a very small pendant, there is no mutton fat white jade with such a good texture, and even some white and green jade already contain a lot of aura. On the trading platform, the aura value of about 1.5 is directly displayed.

For Xiao Chu's classmate to annex the real estate of the two spies, all parties did not make any obstruction, and even in the formalities, it was very convenient, he didn't even have to come forward, and the transfer was completed for him directly.

After the affairs of all parties were settled, Xiao Chu suddenly became idle.

Suddenly, he discovered a strange idea. What would it be like to make a cooling barrel for an electromagnetic cannon with a 10,000-year-old cold iron? The 10,000-year-old cold iron can absorb heat within a certain range without limit, only a small amount of low-temperature nitrogen is needed, this thing can absorb all the heat, and the extremely high temperature after the electromagnetic cannon is fired will stimulate the explosive absorption of the 10,000-year-old cold iron, and the heat dissipation effect is even more amazing.

Even if you add some of this stuff to the barrel, hehe, then the machine gun doesn't have to worry about heat dissipation.

With current technology, it would not be a problem for the Gatling gun to fire for two or three minutes in a row.

Speaking of six-barreled machine guns, the theoretical rate of fire is 8,000 rounds, but in fact, the real rate of fire is only about four or five thousand rounds per minute, and this thing seems to be able to pull the trigger and shoot continuously for a long time. But that's definitely a conjecture result, with the current material strength, the 7.62 mm M134, 6000 rounds per minute at full speed, 30 seconds of continuous firing will have to lie on your stomach, and the barrel can burn you down. Even on the battlefield of Annan later, the brains of the old rice were opened, and some soldiers came up with the idea of using carbon dioxide fire extinguishers to cool them. Not to mention, the effect is really good, even if it is the ultimate rate of fire, it is not a problem to shoot 10,000 rounds of ammunition at all.

The price of an aircraft magazine feeder for just 10,000 rounds is much more expensive than a machine gun.
