Chapter 382

When Zhou Zhou was pulled to rest by Fang Yingqiang, Yang Mu had already taken the cleaning tools to the engine test room.

In fact, the white smoke is gone. Although there is some confusion here, it is not as messy as expected.

The laboratory uses carbon dioxide to extinguish the fire, which can not only isolate oxygen, but also protect these precision instruments from damage. Therefore, most of the engine debris scattered on the ground at the moment, as well as the damage of some surrounding equipment caused by the engine explosion.

Yang Mu put his cleaning tools aside and walked in carefully. Then he stopped, lowered his head and picked up a small fragment under his feet.

This is a piece of burnt black, but you can still see colorful streamer color debris when you turn it over in your hand. The fragment is square, with obvious cracks at the edges and corners, and the fracture is sharp.

Yang Mu, however, recognized that this was the internal part of the engine, which was the blade of the turbine inside the engine.

The reason why mecha's engines use jet engines is that on the planet, these engines can make the mecha move at maximum speed, faster than the internal transmission of electricity. Of course, there are more advanced radiation engines, but that kind of engines are used in the spacecraft a. the jet engines are generally used in the planetary mecha. Of course, they can be replaced when they are used in space war.

But today's jet engine and the original is also very different, mecha early use of nuclear power engine, so the gas inside the jet will be heated, coupled with the rotation of the blade, which brings huge driving force.

Now, the engine uses the energy battery, and the air inside is compressed and ejected. Because the air is pushed out faster by the stirring of the blades, it will also produce a flame, which is generated by the huge friction force when it passes quickly.

But because of this, the current mecha engine will bring higher temperature. When completing some difficult actions, these engines will compress and push out more air in a short time, and with this, it will be higher temperature.

At such a high temperature, the requirements for blade materials are even higher. The fragment in front of us seems to be broken because of this situation.

Yang Mu made a little judgment in his heart, then put down the pieces in his hand, and then collected the pieces around him.

These fragments are also scientific research data. When the time comes, we need to make a comprehensive reproduction to find out the reason for the explosion and the specific location. So Yang Mu picked up the fragments carefully, and then put them in the holographic scanner to scan. The next instrument quickly placed the suspension position of each fragment to form a virtual model.

Yang Mu was doing this seriously. At this time, the door of the test room opened. Yang Mu looked over and found that he was a colleague from the research department, named Ge Ping.

Ge Ping is already 40 years old. His main job is to conduct preliminary research on the failed experiments. Now he comes here for this matter.

Ge Ping came and saw Yang Mu immediately. He said hello immediately. Yang Mu also stood up immediately and called out "Uncle Ge" with a smile

Ge Ping was stunned for a moment, and then he answered with a smile.

However, at the next moment, Ge Ping began his own work. First, he carefully removed all the engines on the frame of mecha one by one, then checked the damaged engines and numbered them again. At the same time, he quickly inspected each part to detect their specific situation at the moment.

Yang Mu was also called by him to help, quickly scan the ground debris, and then with the help of the computer quickly draw a virtual restoration map, and pre assemble with the original engine, and simulate the scattered position.

Supercomputers give a lot of solutions to help reduce a lot of work, but Ge Ping is still in a detailed comparison of the models, and Yang Mu, who has finished the cleaning work, quietly stands aside and watches Geping's work.

Looking at Ge Ping's manual assembly of pieces into parts, Yang Mu can't help but feel that uncle GE's skill is very good. At least he can find the corresponding position immediately after seeing it, which is exactly the position given by the computer.

Not only that, uncle Ge will record the trace of the fragment and preliminary inference while assembling.

Yang Mu praised Yang Mu for his meticulous anti deduction method. Ge Ping occasionally looked up at the big boy standing beside him, staring at his work, and said several points of attention from time to time.

"Look at this fragment. Its center is concave, but it's curled around. At first glance, it looks like it broke and collided with other parts in the engine. But in fact, it was first hit in the middle by other fragments, deformed and then twisted around. This is what it looks like." Ge Ping holds a part and explains it carefully to Yang Mu. Then he picks up a piece of fragment from the side with tweezers. One corner of the fragment meets this fragment, and the corner coincides with the concave place in the middle of the fragment.

Yang Mu looked carefully and nodded solemnly. Ge Ping was satisfied with Yang Mu's learning attitude. He laughed twice and pointed to other places again.After the parts were arranged, Ge Ping quickly found out the reason. It was because the surface of a blade was not completely polished and even, and there was uneven heating under high temperature, so that the blade broke and exploded under high temperature and high speed rotation. At the same time, the surrounding blades were twisted, and finally the surrounding engine was damaged, resulting in the whole explosion.

Seeing all this, Ge Ping sighed, saying that it was a pity that the experiment was not due to design failure, and that it also caused the loss of several engines.

Yang Mu, standing beside him, naturally knew the reason of this matter, but he also understood that it was a good thing that such a design appeared here, because as long as we pay attention to this problem, then we can apply it to practice in order to better ensure the safety of Jijia.

"Uncle Ge, I think the power of this engine is very high. Can such power output also be an important reason for engine damage?" Yang Mu opened his mouth at the right time and said his own ideas.

At this time, uncle Ge read the report, and then nodded: "indeed, this engine is used by a heavy-duty mecha, and the power is higher than that of the ordinary mecha. Moreover, just after the very severe experiment, the defect of the blade was magnified in an instant, so this situation occurred."

Yang Mu also nodded in his heart. Indeed, the various actions just made just now required the engine to have ultra-high explosive force in a short time. Such explosion will bring huge pressure to the engine, and the temperature will rise to a very high value in a shorter time, which will greatly increase the high-temperature pressure on some materials.

"Uncle Ge, is this engine still the most common engine we use?" When Yang Mu asked this question again, he thought of his original design of Mulong mecha. There were some changes in the jet port of that mecha. The form of blade compressed air was almost eliminated, which was quite different from this one.

"That's not true. There are still many engines, such as full channel engines, which automatically generate pressure through multiple air intakes, and more crude engines with semi enclosed chambers. But when it comes to stability and power output, this kind of engine is the most stable."

After finishing his report, Ge Ping added: "of course, the radiation engine for space is better, but the cost-effectiveness is also there."

Yang Mu also understood that this traditional jet engine was the best cost-effective design, but he suddenly remembered one of the drawings in his mind.

"Uncle Gerhardt, what about a hybrid engine with a radiant engine and a jet engine? That should be able to solve a lot of the disadvantages of jet engines, and the price will not be too high Yang Mu asked with great interest, but Uncle Ge laughed and explained again.

"We've been developing and improving that engine for a long time, but unfortunately, we haven't been able to put it into practice, and it's still in the experimental design stage."

Yang Mu also remembered that he had not seen this kind of engine in 20 years. It seems that there is a technical obstacle.

"What is the reason?" Yang Mu asked deeply.

Uncle GE has already reached the door. He pushes the door open, turns around and gives Yang Mu an answer.

"The thermal air and radiation flow stir with each other. The engine can't bear such dynamic and static. It will explode directly when it is used with high power. The explosion power is terrible."

With this sentence, uncle Ge left here, but Yang Mu was stunned for a moment.

I didn't expect that this kind of engine would have such a serious failure, but the design in my mind could not have overcome this problem.

Maybe it's a direction to try.
