I Have a Little Black Hole

Lei Tiantang doesn't have the mood to take care of these things now. Anyway, he has already earned back the money he should have earned. The rest will have to wait for the Four Star Company and the Bangzi Country government to apologize and make compensation, otherwise he will be attacked. It will never stop!

He is now concerned about the rocket engine test run of the technology company. After more than a year of study and design, the rocket research and development work of the technology company has finally entered the fast lane. The most important rocket engine has undergone various After the test, we finally ushered in the key test - the overall test of the engine!

Since the rocket engine test run is very dangerous, as early as last year after the rocket engine design was completed, the technology company invested in the construction of a large engine test bench in a deep mountain not far from Chuhe Fei. 500-ton rocket engine.

The liquid rocket engine test is an important part of the engine development work, which is carried out on various specially constructed test benches, that is, the engine or its components are installed on the test bench.

Under the working conditions and simulation environment provided by the various process systems of the test bench, the engine or assembly can complete the required work according to the predetermined procedure. Evaluate the quality and performance of engines and assemblies.

Currently, three types of sensors are installed in the test rig: pressure, flow and temperature. The strain-type pressure sensor is usually used in the test bench. The principle is to comprehensively use the metal resistance strain effect and the conversion circuit to convert the physical deformation of the measured object into resistance change, and convert the resistance change into electricity output through the conversion circuit.

The resistance strain gauge made of alloy resistance wire wound into a sensitive grid is pasted with an insulating base layer. When the resistance strain gauge is deformed by external force, it will be pasted on the surface of the measured object to cause slight deformation, and the sensitive grid will also be deformed accordingly. Convert physical deformation into power changes and output them.

And because there are several basic principles of test bench design:

First, try to meet the various test requirements put forward by the engine in different development stages, and try to make the test conditions consistent with the working conditions of the engine;

Second, the test equipment is reliable, and the measurement system should have sufficient measurement channels, data capacity and measurement accuracy;

The third is to automate the commissioning, measurement and data processing;

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

Finally, consider a certain versatility and leave room for improvement; also ensure that it is easy to operate! Inspection and maintenance,

There is good economy.

The rocket engine thrust test bench can be divided into two types: steady-state test and dynamic test according to the length of the application test. The former mainly tests the steady-state thrust and pressure performance indicators of the engine, while the latter focuses on the transition process and descent of the thrust and pressure rising stage. Research on the variation characteristics of aftereffect impulse.

The 500-ton rocket engine test bench designed by the technology company is a composite test bench. In addition to using more advanced technology in design, the material company provides various high-performance test benches. Materials are also the most important support for its construction. Without materials with superior performance, such a rocket engine test drive will have to go through several test benches to complete!

At this time, a rocket engine has been installed on the test bench, just waiting to officially start the test. Since it is the first time to perform such an operation, the company's experts are making a final comprehensive check on whether the performance of all equipment is in good condition. Whether the system is normal, whether the connection with the rocket engine is stable, etc.

Lei Tiantang looked at the big guy composed of 9 single rocket engines on the monitoring screen and asked Kong Yuxiao who was nervous beside him: Relax! It has gone through so many single-machine tests and other tests. , and has also undergone many simulation tests of supercomputers, you should have more confidence in the company's technology!

Everyone has worked hard for so long, just waiting for our own rocket to go to the sky! If you can't even pass such a test, that's not a denial of everyone's hard work!

Boss, it's easy for you to say! How can I not be nervous! You drag any person here and ask them if they are nervous, don't look at our technology company's current sales of home robots, but most of the credit is the boss. of!

This rocket project is the result of everyone's own efforts from beginning to end. Although it has passed the artificial intelligence 'origin' tens of thousands of simulation tests, the actual situation is still different from the simulation, in case something goes wrong , that will be a big blow to everyone! Kong Yu said with a smile.

Haha! 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 things ready at the venue? Lei Tiantang smiled and changed the subject. road.

Of course we have already prepared, how can such an important thing not be prepared in advance, we have purchased a large piece of land in Hai Province to build our rocket launch base, the country already has a rocket launch base there, we Looked there too!

Adjacent to the sea, it not only has good sea transportation conditions, but also has good safety in the rocket navigation area and the wreckage area. It can undertake the launch tasks of geosynchronous orbit satellites, high-mass polar-orbit satellites, large-tonnage space stations, cargo spacecraft, deep space probes, etc., and our company's rockets will basically perform such tasks in the future.

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

That's good, but the land you bought has already considered the company's multiple launch missions in the future, right? After all, our company will need to launch a lot of various spacecraft in the future. It's not enough to build just one launch pad! Lei Tian Tang asked.

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

That's good! Check it out! The test drive has officially started! Ha, watching it at the scene is really different from watching it on TV! Lei Tiantang was in a good mood when he saw the streamlined flames ejected from the tail of the rocket engine.

Neither he nor Kong Yuxiao bothered with their work, nor did they think about doing superficial work, shouting The test starts! Such things, it would make people feel very vain to waste time and not talk about it.
