Chapter 1541

As soon as Tian Lu was talking, he listened to the sound of bang ~ ~. When he looked back, his face was scared white, and Tian Changmao fell straight on the sofa.

As soon as Tian Lu hurried forward, he shouted anxiously, pinched the people, held his chest, and poured several quick acting heart-saving pills. After a while, he brought Tian Changmao over.

"I said little one ~ ~ ~ grandpa's heart is not very good ~ ~ ~ can you stop talking so suddenly ~ ~"

Tian Changmao's first words made Tian Lu blush with shame, so he quickly explained: "I was excited to discover the secret of the excellent performance of dpz-2d liquid oxygen kerosene rocket engine. I really didn't expect... But Grandpa, dpz-2d liquid oxygen kerosene rocket engine still proves my previous view that the relationship between aviation and aerospace is getting closer and closer, and the two are simply separated and developed in parallel like our country It's very inappropriate.

If you don't believe it, look at the former Soviet Union and the United States. They are not only the leader in rocket engines, but also the world leader in aeroengines and gas turbines. The gas turbine pump in liquid rocket engines is actually a small gas turbine.

However, the gas turbine in daily use is an ordinary fuel without oxidant, while the rocket engine uses a special low-temperature liquid fuel, but in any case, the basis of the two is consistent and common.

Because of this, the former Soviet Union and the United States, which have made breakthroughs in aeroengines and gas turbines, have also made remarkable achievements in gas turbine pumps on rocket engines.

Similarly, China Tengfei, the parent company of ztm-nb space exploration company, is also proud of China in terms of aeroengines, industrial gas turbines and related application materials. In that case, it is very simple for them to integrate their relevant technologies and materials and develop a high-performance rocket engine gas turbine pump... "

"You mean, aerospace products are made by aviation?"

At this moment, Mr. Tian Changmao is still a little confused and has no way. Since he joined the work, what Tian Changmao saw and heard is that aerospace belongs to aerospace and aviation belongs to aviation.

Not only that, according to the overall planning of the country at that time, the status of aerospace vaguely exceeded the level of aviation.

Barony has the final say that the astronauts of Tian Chang Mao are hardworking, dedicated and proud, so that the whole space system is still an independent kingdom.

Over the years, China Tengfei has been involved in the aerospace business because of the reform. However, under the closed system of the entire aerospace system, China Tengfei's aerospace business has also been compressed to an extremely narrow scope. Basically, in addition to several key projects of the headquarters and China Tengfei's unique satellite rapid manufacturing capability, China Tengfei is basically connected with the core of launch vehicle and long-range missile I can't touch it.

Because in the eyes of Tian Changmao, a person who is engaged in aviation is playing the piano indiscriminately. The work in the atmosphere wants to play with things outside the atmosphere without looking at the middle atmosphere.

Therefore, over the years, China has taken off to seek advice with an open mind, visit and study in the aerospace system, and staged some big plays of digging and robbing people from time to time.

In addition to some courtesy return visits to China, the old manufacturers of aerospace systems are basically the same old and dead methods, which are extremely arrogant.

Therefore, closure creates rigidity, and rigidity will inevitably create its own complacency.

You should know that the liquid oxygen kerosene of the former Soviet Union and the liquid hydrogen liquid oxygen of the United States have proved more than once that they are the kings in the future aerospace field.

However, the space conservatives represented by Tian Changmao and others have been holding on to the previous generation of propellants such as unsymmetrical dimethylhydrazine and nitrous oxide.

It is not only widely used in the improved CZ-3, but also inherited and continued the newly developed CZ-4.

The reason is that propellants such as unsymmetrical dimethylhydrazine and nitrous oxide are more mature and can maintain a high launch success rate of the whole space launch.

As a result, the whole aerospace field, especially the civil aerospace business, has no power in the investment and R & D of new technologies and processes.

Just eat your old money.

What is environmentally friendly, toxic and costly, as long as the spacecraft can be smoothly sent out of the atmosphere.

Mr. Tian changmaotian thought so and did so. But after he retired, the domestic aerospace business lost one after another due to environmental protection and harmful substances, including several large orders in New Zealand, Australia, Singapore and Indonesia. People of insight in the aerospace field realized that they wanted to change.

But at this time, the soil of innovation and enterprising has been almost destroyed by the complacency of those years. It will take at least eight to ten years to cultivate, so it is impossible to change the current situation of domestic space launch in the short term.

For this reason, Tian Changmao has attracted much criticism behind him, because it is his conservatism that leads to today's situation.

But if there is any big mistake, it really can't be found, so many people scold behind their backs. It's really hard to say what way Tian Changmao can do.

But for Tian Changmao, who has been strong all his life, he can't hang his old face. Moreover, in his position, the things in front of him have long been without desire and demand. What he cares more is the name behind him. If he is scolded like this, he can't rest in peace even if he dies.

Therefore, Tian Changmao also wants to give full play to the waste heat and wants to make great efforts to help turn the aerospace field. Otherwise, it is impossible to still serve as the honorary president of the aerospace business association at the age of 80. I should have urged my grandson to have a great grandson to play with him.

However, the problem is that there was too much inertia left in those years. If you want to change, you can't do it in a moment and a half. Therefore, even if Mr. Tian worked hard and worked hard, the results in recent years are not great.

However, just when Mr. Tian was ready to die and work until he couldn't move, Zhuang Jianye suddenly pushed the dpz-2d liquid oxygen kerosene rocket engine of ztm-nb space exploration company to the stage by means of live broadcasting.

Large thrust, light weight, strong specific impulse and high thrust weight ratio.

The most important thing is the environment-friendly and low-cost liquid oxygen kerosene system. It can be said that the dpz-2d liquid oxygen kerosene rocket engine has been the dream of astronauts for so many years.

Otherwise, Tian Changmao wouldn't be surprised to look like that, so that he was wondering whether Zhuang Jianye boasted that he was an aviation man. How could he produce such a high-level rocket engine?

However, this question was just about to occupy the last highland of the brain, but Tian Luyi's words made him realize that it was difficult for Zhuang Jianye to be a high-level rocket engine? With China's strong achievements in aeroengines and gas turbines, it can be achieved with a little transformation.

So Zhuang Jianye doesn't build rocket engines. He's just a porter with cutting-edge technology in related fields!
