But everyone didn't understand how this thing was made, but they knew that this thing absorbed the surrounding carbon and grew naturally.

Later, some people wanted to reactivate this kind of thing, but there was no hope, according to the method of Chu Feng and their World Sect, they were killed by cold light, and all the nanoworms could no longer be activated.

As for the original nanoworms, they are firmly protected in an incubator, and several fully automatic electromagnetic cannons erected around them have already destroyed several flies, and of course there are no flies in the sealed cabin.

Now, even if you want to negotiate conditions with Xiao Chu, it is difficult, because Xiao Chu has completely hidden.

He's working on something that crosses the generations, the super micro engine.

He was joined by a bunch of engine specialists, three of whom were seconded from abroad.

The production research of large engines is completely different from that of small engines, and it is not a problem for so many people to use data to copy a small engine, but it is impossible to get a large engine.

And rocket engines and aircraft engines are not a design idea at all, why should rockets be divided into several stages? Can't it be made to the first level?

Yes, why can't it, didn't Lao Mi get a single-stage rocket into space before? And we in Huaxia either have a three-stage rocket or at least a two-stage rocket.

Why?

Material.

The material of the rocket engine simply cannot withstand the thermal deformation caused by long-term combustion, especially the first-stage rocket, a little bit of a bad pool, that is the end of the explosion, many rocket engine explosions in history, many are caused by the material is not strong enough.

Small rockets, such as rocket engines for various air-to-air missiles, do not need too long flight time, and the flight speed of one or two thousand meters per second, tens of kilometers, tens of seconds, as long as the material of the combustion chamber is thick enough, it has already hit the target before it melts.

Of course, long-range air-to-air missiles are not unavailable, such as the AIM-154 Immortal Bird missile, which is claimed to be murderous and reaches a range of 200 kilometers. But, yes, yes.

Because the radar of ordinary fighters cannot detect that far at all, if you want to confirm enemy aircraft from a distance of 100 kilometers, you need early warning aircraft. And when a missile is launched from 200 kilometers away and flies in front of the enemy, people have already been prepared.

Of course, if you are talking about asymmetrical combat, for example, the other side even has early warning aircraft, and the radar is still the old model of the Mao sub system, then wouldn't it be too wasteful to use immortal birds? It's a million-dollar knife.

Moreover, because the flight speed of the Immortal Bird missile is so much, let alone countermeasures or decoy missiles, even some pilots can predict and dodge it.

In general, if you want distance, you don't need speed, if you want speed, you don't need distance, and if you have both, then pay for it and use better materials.

Just like the super missile engine that Xiao Chu got from classmate, the materials produced are not strong enough, what should I do? Press with a stamping machine or forging press.

Fortunately, there is a small stamping machine in the equipment sent this time, although it cannot reach 10,000 tons, but it can still handle 8,000 tons of small stamping parts.

Moreover, small parts that are less than ten centimeters, not to mention 8,000-ton stamping machines, and 3,000-ton stamping machines are not enough. The pressure value per unit area is absolutely up to standard.

After adding a variety of rare elements, the processing difficulty of the parts is increased exponentially, and the accuracy error of the most precise parts is less than 1 micron level, which is also to kneel. This is all catching up with the accuracy of astronautics.

Fortunately, the temperature difference variables of the parts are ridiculously low, and it is not difficult for the processor to assemble them with an advanced microscope. Even at the same time, the pile of nanobots that Xiao Chu bought from the interstellar trading platform were also assembling this thing.

The turbofan engine of the spiral turbine, the person who can come up with this thing basically belongs to the brain pumping level, the two things that are not matched at all are forcibly kneaded together, and the accuracy requirements are so high that the three engineers who assembled the avionics parts are about to collapse, and what is even more nonsense is that the barrel body of less than 100 millimeters has to add eight vector servos, fortunately, the requirements for the resistance strength of this thing are relatively low, and the combination of high-temperature crystals and constant gold is enough to deal with it, otherwise, the high-temperature jet stream of more than 4,000 degrees, It can blow the entire piece of steel instantly.

Moreover, what makes this thing even more ferocious is that oxygen can be added to have the effect of afterburner. The 1500 ml hydraulic tank provides only 15 ml of liquid oxygen to maintain the afterburner state for 1 second, doubling the output efficiency. In fact, the liquid oxygen tank can be designed to be a little larger. In fact, in the original design, the storage capacity of the liquid oxygen tank was only 450 milliliters, because the combustion chamber of the engine was completely liquefied before the oxygen was burned, and the core temperature could reach more than 8,000 degrees. After Xiao Chu's calculations with an alien computer, it was found that even the combustion chamber, which was almost entirely made of constant gold and 10,000-year-old cold iron, could only last for about 100 seconds at a temperature of more than 8,000 degrees, and no matter how much, it would collapse.

But even so, the thrust-to-weight ratio of this engine is extremely vicious.

In addition, because it is a small turbofan engine, it is not a simple structure like a turbojet engine, and the fuel consumption is quite amazing.

Let's put it this way, if you use this thing to carry all the fuel and use it to design a mechanical airplane, it can propel this plane around the earth in a full circle. If two of these micro engines are used to drive a small UAV with a wingspan weighing 200 kilograms, it is estimated that it is completely stress-free to fly 10,000 kilometers.

And the size of this thing is still speechless, 618 mm long, 87 mm in diameter, weighs only 3570 grams, and even after the optimization of alien construction machinery robots, there is also an ultimate version of the finished product, 319 mm long, 68 mm in diameter, and a simplified version weighing only 1250 grams, and in terms of thrust weight, it is only 15% less than the original design.

Let's put it this way, as far as the original design engine is concerned, the maximum thrust weight of the engine weighing only 3570 grams can vertically push more than 150 kilograms of heavy objects, and after the oxygenation combustion, it can push more than 300 kilograms of things straight into the sky.

You know, the most advanced small engines nowadays can achieve this thrust-to-weight ratio of half, let alone large engines.

Of course, there are rocket engines that have a higher thrust-to-weight ratio, but that thing can burn for 20 seconds?

And this engine can continue to output, even higher than the energy-saving efficiency of large engines, but Xiao Chu hasn't figured out what to use as its carrier.
