Academician Wang said with some regret, "If there is an air-breathing engine that can explode such a huge power, maybe the payload of the Golden Wing Dapeng can be further increased."
"Ha ha, there are gains and losses. Things are not as beautiful as ten." Huang Xiuyuan smiled and shook his head.
Golden wing Dapeng engine is a detonation rocket engine with N2 high-energy fuel, which can generate huge instantaneous explosive force and push thousands of tons of things to the top of stratosphere.
Generally, the energy density of solid fuel is too low, and the instantaneous explosive force of liquid oxygen kerosene in liquid fuel is not enough to push the high charge to the top of stratosphere.
N2 fuel is the best choice at present.
"Don’t talk about this, Xiu Yuan. Before you confessed another project, Fanghe seems to have been almost finished." Academician Wang woke up.
"Oh?" Huang Xiuyuan one leng immediately to the interest "let’s go and see".
The two of them came to another satellite assembly factory, Eagle Aerospace. Although it was established for a short time, it obtained a large number of technicians by digging the wall.
Before the project of Qianfeipeng launch platform was established, Eagle Aerospace did not sit still, but there were several projects.
The Chinese river team is responsible for the ultra-low orbit satellite R&D project, which Huang Xiuyuan personally explained.
Enter the satellite assembly factory.
A middle-aged man with a somewhat horse-faced face is discussing something with several researchers. He is a worker at Fanghe No.1 Institute of Space Engineering who is engaged in satellite and spacecraft design.
"Laos heard that you have achieved results?"
As soon as I heard this sound, Fanghe suddenly woke up and walked over in three steps and two steps. "Chairman, welcome to guide the project. We have designed a prototype initially."
"Show me"
"good"
A group of people came to the core area of the satellite assembly factory, where a satellite was displayed. Judging from the wingspan of the solar panel and the size of the equipment, it should be a medium-sized satellite, with an estimated weight of about 2 tons.
Fanghe introduced a basic parameter, and the weight was indeed 12 tons.
The design of this satellite is very strange, especially the horn on the head, which makes people suspect that this thing is some kind of laser.
But in fact, this thing is not a laser, but a static particle finder, which can search for hydrogen and helium along the way through static field.
The reason for searching these particles is very simple, because this satellite mining engine is a laser plasma engine.
Laser plasma engine working medium is the power source that gas is separated into plasma by instantaneous high-energy laser and then sprayed out.
On the one hand, the power of laser plasma engine comes from solar panel, on the other hand, it is temperature difference. At present, magnetic fluid generation system is also tested
According to the plan, the orbit of this type of satellite is an ultra-low orbit area with an altitude of 21~24 kilometers, which has a relatively rich gas content for the satellite to search for working medium.
On the other hand, ultra-low orbit operation does not need to start the engine at all times, usually when the satellite altitude drops to near the critical altitude.
Why Huang Xiuyuan is obsessed with ultra-low orbit satellites? Mainly, this type of satellite has a very good advantage, that is, it is very close to the ground.
Whether it is reconnaissance monitoring or positioning communication, ultra-low orbit satellites have high orbit satellite method to achieve clarity and accuracy
However, the disadvantage of ultra-low orbit satellites is that their service life is very short, mainly due to a large amount of gas near 1~5 kilometers in low earth orbit.
These gases will constantly impact the spacecraft, and when the gas resistance is a little, the spacecraft will gradually fall to the ground.
Even the current Tiangong and the international community are falling every year, but the speed is very slow, which is not obvious.
Even so, every once in a while, it is still necessary to lift the height of the orbit by the engine to avoid being pulled by the atmosphere.
However, the 21~24 km ultra-low orbit spacecraft can adopt large elliptical orbit to realize a period of ultra-low orbit window.
The Fanghe team designed this satellite to change the normal laser plasma engine, static particle finder and multiple systems to ensure that the satellite can run in ultra-low orbit for 24 hours.
It is even possible to carry out the rail charging industry to transport a large number of working fluids through long-11 rockets and then charge them in orbit.
Chapter five hundred and twenty-five Processing
Shanghai
Time information branch office building
The general manager’s office just finished the Spring Festival, and the general manager Zhu called the assistant in to report that the Spring Festival workers were going to give the Spring Festival employees a holiday and pay subsidies.
He didn’t wait for the assistant, but he waited for the assistant. Xiaoshan, the head of Du ‘an Department, saw Xiaoshan push the office door and put a document on the other side’s desktop.
"Xiao group leader this ….." Some have a guilty conscience Zhu asked.
However, Xiaoshan looked indifferent and said, "Look for yourself!"
Gollum! Zhu trembled slightly and turned over the file.
[On the evening of July 11th, 2013, I checked into RoomNo. of Moduzhu Hotel at 24: 00, and then the female artist entered the room. They left at 3: 00 the next morning …]
[213 … A large number of hot searches and trumpet plugins have appeared in the female artist’s time blog Modu social circle and multiple platforms …]
［213……］
Xiaoshan sneered and asked, "If you dare to do it, you must dare to be paid by Huamen Film and Changxin Entertainment for 354,236.91 million yuan and a few silicone monsters."
Sweating profusely, Zhu didn’t know what to answer at the moment.
"You have an annual salary of 1.73 million, plus virtual stock dividends and company benefits. Don’t you have billions of dollars for more than ten years? Will it be? "
"I was wrong. Please give me another chance. I will make amends …"
Xiaoshan roared, "It’s too late! The company will not allow moths. You should have thought of today’s show the moment you reached out. "
According to the employee contract, Zhuchang will be very miserable.
Not only the annual income, welfare, virtual stocks and dividends are returned to the company, but also the liquidated damages of 150,000 yuan, non-competition restriction and lifelong blacklist are required to be investigated for legal responsibility.
The Ministry of Safety has a special legal department. This legal department and the Ministry of Industry law are the laws of the Ministry of Industry, mainly engaged in business, while the Ministry of Safety law is to provide legal aid and support employees to deal with moths in the Ministry.
Especially for the Ministry of moths, the Abe law will not be merciful, but will be directly engaged in the dead.
Soon, four employees of Modu Time Information Branch were taken away for investigation, and the Ministry of Industry had already arranged for preparatory employees to come directly to replace them.
At the moment when Zhu was taken away, the whole person was extremely decadent as if he were a teenager.
And Suiren magazine, Suiren department network have published the treatment of a number of moths. Guys like Zhu are estimated to be unable to turn over for a generation.
At the same time
