With the promulgation of the Mass Projector Lend-Lease Act, the International Conference on Outer Space has finally come to an end.

Although Maxwell and others were very dissatisfied, they had to admit that the situation was stronger than people.

Obviously, the introduction of the Lend-Lease Act has given the Mi Lijia and other countries a step down, but the bidding qualification is indeed a very troublesome matter.

In particular, some of the clauses, such as what is friendly to the Eastern Tang-Galactic Alliance, such as the absence of disputes......

Those who had historical problems with the Eastern Tang Dynasty suddenly became bitter, among which Mao Xiong and Tianzhu felt the most tricky.

After all, Trans-Khingan, Vladivostok, Lake Baikal, Tangnu-Ulianghai, and Sakhalin are the historical problems of Mao Xiong and the Eastern Tang Dynasty; The southern side of the Himalayas is a matter of history in Tianzhu and the Eastern Tang Dynasty.

These issues can already be shelved disputes, and now that the Eastern Tang Dynasty is powerful, shelving disputes is no longer applicable, and it is time to use the territory that has been our territory since ancient times.

Anyway, if these issues are not negotiated, Dongtang will not grant the bidding qualifications to Mao Xiong and Tianzhu.

Therefore, before the completion of the construction of the Wenchang mass projector, it is an opportunity for various countries and the Eastern Tang-Galactic Alliance to contact and negotiate privately, and if this opportunity is missed, it may miss the great era of entering outer space.

Except for those who eat and wait for death, Tianzhu and Hairy Bear are definitely not willing to give up the opportunity to enter outer space.

After the conclusion of the International Conference on Outer Space, the Space Development Commission successively promulgated a series of legal provisions, such as the "Technical Standards for Spacecraft", "Technical Standards for Space Stations", "Regulations on the Administration of Astronautics", "Law on the Administration of Space Industry", "Law on Space Security", and so on.

Although these legal provisions were promulgated by the Space Development Commission itself, to a certain extent, these legal provisions are very important in international law.

If they want to lease a mass projector, they must comply with these laws issued by the Space Development Committee, unless they don't want to lease a mass projector.

The other side.

Dongdao Hualien, Cosmic Dynamics.

Cosmos Propulsion is one of the subsidiaries of Galaxy Aerospace Industry Group, which is responsible for the production and development of special aerospace engines.

They produce a range of engines such as Hsiungfeng series rocket engines, spacecraft engines, space station engines, satellite engines, etc.

At this time, in one of the production halls of the Cosmos Dynamics, workers are working around a huge engine.

"Mr. Li, welcome to inspect the work." A middle-aged man in a Mediterranean plaid shirt said with a smile.

Li Jianhua glanced at the engine being assembled and asked, "National Day, is this engine a new product?"

"Yes, Mr. Li, this is a new generation of engine developed by our company recently, specially developed for 500-ton spacecraft." Lin Guoqing hurriedly introduced.

"A new generation of engines and spaceships? Why didn't I hear you had this plan?" Li Jianhua asked in surprise.

"Our engine project was approved in December, and the new generation of 500-ton spacecraft is a project that has just been established in the past few days, and it is currently under internal discussion, and I believe it will be submitted to the management committee for approval soon." Lin Guoqing hurriedly explained.

Li Jianhua opened the holographic watch to check the situation and found that the Cosmos Power Company did have an engine project in December.

"Wouldn't it be too much of a hurry to develop a 500-ton spacecraft so soon?"

Lin Guoqing pondered for a while and then replied: "From a technical point of view, a 500-ton spacecraft is no problem, our technology can do it to this extent, and the other 500-ton spacecraft can make full use of the launch resources of the mass projector." ”

Although Lin Guoqing said it very plainly, Li Jianhua still didn't understand: "Why can we make full use of the launch resources of the mass projector?"

"The basalt-class transport can transport 60 tons of cargo to low-earth orbit at a time, and the 500-ton spacecraft can transport 300 tons of cargo to low-earth orbit at a time, but the two are used for the same time as the mass projector." Lin Guoqing explained.

"I see, where is the progress of the new engine?" Li Jianhua asked.

Lin Guoqing pointed to the engine in front of him and replied: "We have now reached the test stage, this is the second prototype, and the first one is in the workshop next door." ”

Lin Guoqing took Li Jianhua to inspect the workshop for more than half an hour before Li Jianhua left here with people.

The workers and researchers on the shop floor continued to work.

"Dr. Kudo, there's something wrong with the electronic control system you're responsible for." Cai Xin, the chief engineer of the project, said with a supercomputer simulation result.

Dr. Kudo came from the Sun Country Space Agency, and in fact, there are not a few scientists from Gao Li and the Sun Country in the Galaxy Aerospace Industry Group.

As for the question of whether it will be leaked, the internal review of the Galaxy Consortium is very powerful, and those who have problems have long been excluded, after all, the brain reader is an unsolvable existence, and with the supervision of artificial intelligence, no one can infiltrate the Galaxy Consortium.

"Cai Sang, what's the problem?" Dr. Kudo asked nervously.

Cai Xin handed a report to the other party: "This is the result of a supercomputing simulation, you can see for yourself." ”

After taking it, Dr. Kudo hurriedly flipped through it, he looked around his head while looking at it, and after a while, he suddenly realized: "It's the parameters here that are too big." ”

After discovering the problem, Dr. Kudo hurriedly turned on the holographic computer and checked his design plan, and after a while, he found that one of the parameters was wrong, and 24.7161 became 24.1161.

Data errors are a very common thing in the R&D process, especially for very complex R&D projects, where data can easily be hundreds or thousands, and a decimal point error can make a huge difference in results.

Cai Xin, as the chief engineer, is also very busy.

"Chief Engineer Cai, my spout design has been completed." A tall, thin young man said.

Cai Xin took the other party's information and studied it carefully for a while, then he raised his head and asked, "Guowen, will the thickness of the pipe wall of the nozzle be too thin?"

The tall and thin Wang Guowen shook his head and explained: "No, I used a hybrid gel to plate on the nozzle, and I used three layers, both in terms of high temperature resistance and structural strength, which is stronger than the first-generation engine." ”

"The hybrid gel is such a good thing." Cai Xin sighed.

"Of course, this hybrid gel is a good thing, and after using this material in the combustion chamber and nozzle of our new generation engine, the power has been increased, but the weight has not become much larger." Wang Guowen said with a smile.

In fact, if you compare it, you can see the difference, the same hydrogen and oxygen engine used by the Xuanwu-class spacecraft, the first generation of the main engine weighs 3.4 tons and can provide 135 tons of power, while the second generation of the main engine (coated with mixed gel film) weighs 2.3 tons and can provide 157 tons of power.

This so-called second-generation engine is just a minor change, and the engine that has been overhauled is the third-generation engine, which is still the engine that Cai Xin and they are developing now.

This engine, in their design scheme, is expected to weigh about 6.5 tons, and the power will reach between 600~700 tons.

Mainly after the hybrid gel coating process, many materials have been deleted, and the thickness of the chamber wall of the combustion chamber is more than 60% thinner than the previous two generations, but the mechanical strength has been increased by 46%.

The new material has brought a powerful boost to the further development of the engine, and even made the design more simple and crude.
