Chapter 345

Lei Tiantang doesn't have the mood to take care of these things now. Anyway, he has earned his own money. The rest will wait until the four star company and the Bangzi government apologize and compensate, otherwise, he will never stop these attacks!

Now he is concerned about the rocket engine test run of science and technology company. After more than a year's study and design, the research and development work of the technology company's rocket has finally entered the fast track. After a variety of tests, the most important rocket engine has finally ushered in the key test - engine overall test!

Since the rocket engine test run is very dangerous, as early as last year, after the rocket engine design was completed, the science and technology company invested in the construction of a large engine test bed in a deep mountain not far from the clutch, which can test the maximum of 500 tons of rocket engines.

Liquid rocket engine test is an important part of engine development. It is carried out on various specially built test stands, that is, the engine or its combination is installed on the test bench.

Under the working conditions and simulation environment provided by each process system of the test bed, the engine or assembly can complete the required work according to the predetermined procedure. The main purpose is to verify the feasibility of the design, the reliability of the process, and the method of examination and debugging, and to evaluate the quality and performance of the engine and the assembly.

At present, there are three types of sensors in the test bed: pressure, flow and temperature. Strain type pressure sensor is usually used in the test bench. Its principle is to use metal resistance strain effect and conversion circuit to convert the physical deformation of the measured object into resistance change, and then change the resistance change into electricity output through the conversion circuit.

The resistance strain gauge made of alloy resistance wire wound into sensitive gate is pasted with insulating substrate. When the resistance strain gauge is deformed by external force, it will be pasted on the surface of the object to be measured, and the sensitive gate will also be deformed accordingly. The resistance value of the resistance strain gauge will be changed and equivalent transformation will be carried out through the conversion circuit, so that the physical deformation will be converted into the output of electric quantity change.

There are several basic principles for the design of the test bed:

firstly, it is necessary to meet all kinds of test requirements proposed by the engine in different development stages, and try to make the test conditions and the working conditions of the engine consistent as far as possible;

the second is that the test equipment works reliably, and the measurement system should have sufficient measurement channels, data capacity and measurement accuracy;

The third is to make the test run, measurement and data processing automatic;

the fourth is to ensure the safety of the staff and test equipment, with complete explosion-proof, anti-virus, anti-corrosion and noise elimination measures;

finally, it is necessary to consider certain versatility and leave room for improvement; it is also necessary to ensure that it is easy to operate, check and maintain, and has good economy.

According to the test time, rocket engine thrust test bench can be divided into two types: Steady-state test bench and dynamic test bench. The former mainly tests the steady-state thrust and pressure performance indexes of the engine, while the latter pays attention to the research on the change characteristics of thrust and pressure in the transition process and after the descent phase.

The 500 ton rocket engine test bed designed by the science and technology company is a composite test bed. In addition to adopting more advanced technology in design, the high-performance materials provided by the material company are also the most important support for its construction. Without superior materials, the rocket engine test-bed will have to go through well A few test stands to complete!

At this time, a rocket engine has been installed on the test bench, and it is waiting for the test to begin. Since it is the first time to carry out such operation, the experts of the company are conducting a final comprehensive inspection on the performance of all equipment, whether each system is normal, and whether the connection with the rocket engine is stable.

Lei Tiantang looked at the big guy composed of nine single rocket engines on the monitoring screen and asked with a smile to the nervous Kong Yu: "relax! After so many stand-alone tests and other tests, as well as many simulation tests of supercomputers, you should have more confidence in the company's technology!

We have worked hard for so long, waiting for our own rocket to go to heaven! If you can't even pass such a test, it's a denial of everyone's hard work

"It's easy for you, boss! How can I not be nervous! You pull anyone here and ask them if they are nervous. Although our technology company sells home robots so well now, most of the credit is due to the boss!

This rocket project is the result of our own efforts from the beginning to the end. Although it has passed tens of thousands of simulation tests on the origin of artificial intelligence, the actual situation is still different from the simulated one. If something goes wrong, it will be a great blow to everyone! " Kong Yu laughed and make complaints about it.

"Ha ha! Well, let's talk about other topics. After this test, it should be the actual launch and recovery test of the rocket engine, right? Are we all ready for the venue? " Lei Tian Tang smiles and changes the topic.

"Of course, we have already prepared for such an important matter. How can we not prepare in advance? We have purchased a large piece of land in Hainan Province to build our rocket launch base. The country already has a rocket launch base there, and we also have a fancy to it!It is adjacent to the sea, which not only has good sea transportation conditions, but also has good security in rocket navigation area and debris falling area. It can undertake the launching missions of geosynchronous orbit satellites, high mass polar orbit satellites, large tonnage space stations, cargo spaceships, deep space probes, etc., and our company's rockets will basically carry out such tasks in the future.

Therefore, the construction of a new space launch center in Hainan Province can take advantage of the advantages of low latitude, improve the carrying capacity of geosynchronous orbit satellites, extend the service life of satellites, and have a high cost-effectiveness ratio. " Kong Yu explained with a smile.

"That's good, but have you considered the company's multiple launch missions in the future? After all, our company will need to launch a variety of spacecraft in the future, if only build a launch pad is not enough! " Lei Tiantang asked.

"Of course, boss, even the future boss, your spaceship launch can be carried out there! The land is absolutely enough! " Kong Yu replied with a smile.

"Good! Look! The test run has officially started! Ha, it's not the same as watching it on TV Looking at the streamlined flame from the tail of the rocket engine, Lei Tiantang was in a good mood.

He and Kong Yuxiao did not disturb their work, nor did they want to do superficial work. They called out "test begins!" Such a thing, to waste time without saying, will also make people feel very vain.
