Super Weapon Swap System

From the weapons cemetery, we found a black duck electronic reconnaissance plane, exchanged it, smashed it, handed it to Xiong Guoren, unpacked it, loaded it into a transport plane and took it away.

Find the GPS satellite design data from the weapon data cemetery and give it to sun Lao and others. Let them copy it according to the real objects and data, so that the progress will be faster. Qin Guan's purpose is to network his own Beidou system when the eagle people's GPS system is networked, at least to cover the area of the Han country and gradually expand to the whole world.

If GPS gets ahead and expands to the world, it will not be easy to promote our own Beidou system. This is the situation of future generations. It is strongly promoted with the support of the state. For example, all trucks must install Beidou system, etc.

Only when the amount of use is large and the R & D cost is reduced, the cost will be lower and lower. Otherwise, it will go into a dead cycle and the project will die in the end.

"The No. 1 chief has agreed to the space plan." major Yang said to Qin Guan next to him. At this time, they were walking in failure, which almost led to the dismounting of the hydrogen and oxygen engine. However, Ren advocated to continue research and development. With his strong insistence, he had to adopt this advanced engine. Later, he encountered failure. In 1984, Dongfanghong 2 only entered the small elliptical orbit and did not reach the synchronous orbit because the secondary ignition of the hydrogen oxygen engine was not successful.

It is very difficult to develop a new engine. Now, Qin Guan said that it is a huge step to develop a high thrust liquid oxygen kerosene engine.

As a veteran of the space rocket engine, Ren personally attended this important meeting.

Unlike other scientific research projects, space engines often do not have any experience and models to learn from. They can only experiment again and again to master complex fluid laws. This new engine is easy to fail before its own side has no contact.

"At present, our most mature is the Long March 2. Its first stage is the dafy6-2 engine, which is the model with the largest thrust. This engine is composed of four liquid engines with a thrust of 75 tons in parallel. That is to say, we have only 75 tons of thrust at hand." Ren continued: "President Qin, the space station you proposed needs a large engine with a thrust of 400 tons, which is difficult to achieve at our current level. Therefore, we want to make a simpler plan first, that is, a liquid oxygen kerosene engine with a thrust of 120 tons. On this basis, we will form our new launch vehicle. We will increase our existing maximum 6-ton near earth launch capacity to 20 ton level. "

When Ren finished, he smiled at Qin Guan: "we may be laughed at by President Qin. Satellites are put everywhere. Only US units that really put satellites don't dare to put satellites."

Qin Guan shook his head: "no, Ren Lao, your plan is more suitable and safer. I agree with you. Our long March-5 is going to be approved?"
