Others laugh at me for being crazy, and I laugh at others for not being able to see through it!

In the eyes of many people, Qin Tian seemed to be on the path of madness, going farther and farther.

Why?

Because, Qin Tian did two great things in a row that could be called against the sky.

The first crazy big thing, play satellites!

It is nothing new for private enterprises to want to have their own data communication satellites, but the slogans have been shouted loudly, but none of them have been put into practice.

Who dares to be the first to eat crabs?

Qin Tian!

At the beginning of June, Qin Tian used two Boeing 737-4OOC cargo planes to transport back four communication satellites with a unit price of up to 200 million US dollars and some related components from Huaxia Aerospace Science and Technology.

At present, the most commonly used satellite communication systems in the world are Inmarsat and Iridium.

Inmarsat has 11 geosynchronous orbit communications satellites in an altitude of 35,000 km, covering a large area of the earth, while Iridium has 66 satellites in low earth orbit, which has a wider coverage but is prone to signal interruption due to satellite movement.

But in any case, for remote areas without base station signal coverage, especially in deserts and oceans, satellite calls are essential, especially after large-scale natural disasters, disaster areas need satellite calls to ensure smooth communication.

Huaxia Aerospace Science and Technology has developed a new generation of satellite telephone system based on advanced international experience and in combination with actual domestic needs, and this kind of high-orbit operation satellite using a large number of advanced technologies is naturally more efficient than the maritime satellite communication system and the Iridium satellite system 30 or 40 years ago, but the price is also more expensive.

It is precisely because the price is too expensive, and there are two satellite call market dominants entrenched, so Huaxia Aerospace Science and Technology has not been able to build its own satellite call network, but I never expected that Qin Tian appeared!

Since it is the most advanced communication satellite, it must be the best in all aspects.

Isn't it cheap? Then buy four in one go, directly global networking, you can always give a batch price, right?

Huaxia Aerospace Technology has been approved by the high-level, and the four packages are priced at 800 million US dollars!

Qin Tian agreed without hesitation, ordered 4 of the most advanced communication satellites, named Weile 1 to 4, and then shipped them back at no expense to make magic changes, so that the performance of these four satellites has increased dramatically, and the cost is naturally no longer just 200 million US dollars.

However, does Qin Tian care about that little drizzle?

Weile Aerospace Technology is registered overseas, and the financial settlement of Qin Tian and Huaxia Aerospace Technology directly uses overseas accounts.

June 24, 2o18, 6:24 a.m.

With a length of nearly 3o meters and a take-off weight of 1o3 tons, the new cZ-6 rocket of Huaxia Aerospace Science and Technology suddenly ignited with the order of the commander, and the high-pressure, high-thrust, non-toxic and non-polluting liquid oxygen kerosene engine suddenly ignited, and the tail nozzle suddenly sprayed dazzling flames.

Smoke rises, fires burst out, and rockets soar into the sky.

Under the precise measurement and control of Huaxia Aerospace Science and Technology, the rocket successfully sent the carrier module into a high orbit after multi-stage separation, and then realized the world-class 100-meter-level satellite orbit control.

From 6:5o to 7:37, with the completion of the synchronization of the four satellites, the aerospace building in Weile Science and Technology City established a satellite-ground data synchronization network, the rocket launch mission was officially completed, and Qin Tian also fulfilled the contract to settle the rocket launch cost to Huaxia Aerospace Science and Technology, 70 million US dollars.

70 million dollars to complete the shooting of four stars with one stone?

Compared with foreign quotations, China really gave Qin Tian a conscience price.

Why? Because Inmarsat, which claims to be the world's leading mobile satellite operator, has launched a maritime satellite, known as the world's largest and most advanced civil communications satellite, a1phasat, and the cost of the satellite alone is $350 million, and the cost of the European Space Agency's rocket launch from the Guyana Space Center is more than $400 million.

Qin Tiancai spent less than 900 million US dollars to get four satellites, so that Weile Group has its own satellite communication network, which can provide necessary data communication services for intelligent robots sold to all over the world 24 hours a day, and also laid a solid foundation for the space home port program, so it is really quite cheap.

……

The second crazy big thing, engage in motivation!

Aviation engine is known as the crown of modern industrial civilization, is the integration of a large number of advanced technology as one of the high-end equipment, without a strong comprehensive industrial strength and strong financial support, ordinary countries simply can not play, even if it can be engaged, the quality is not satisfactory.

GE, Pratt & Whitney, Rolls-Royce RR...... Most of the world's advanced civil aviation and military motives come from these well-known enterprises.

The research of aviation motives has a large investment, a long cycle, and high risks, and there are fewer companies to engage in aerospace motives that require a more powerful thrust-to-weight ratio, and a rocket motive test car will consume hundreds of thousands of dollars of propellant, and how many companies can afford it?

Knowing that there are tigers in the mountains, I prefer to go to the tiger mountains!

If Qin Tian wants to have the "Kunpeng" space cargo spacecraft, he must come up with a space power system that is more advanced than the rocket motive, otherwise how can he send a spacecraft weighing three or four thousand tons after loading cargo into space?

At present, mankind has mastered two relatively mature aerospace power systems, one is the very common chemical propulsion, that is, the solid \/liquid rocket motor uses rapid combustion propellant to produce high-pressure and high-temperature gas, and jet produces power, this power system is mature and stable, but the energy conversion efficiency is low, and it was first abandoned.

And the second is the electric propulsion system.

The plasma motor is a relatively mature electric propulsion system, which first ionizes the gaseous substance into ions, and then sprays it with a strong electric field to obtain the reaction force.

Compared with the traditional rocket motor, the plasma motor is of course more efficient, carrying the same weight of fuel, the plasma motor can produce more durable power through ionization and injection, but the disadvantage is also obvious, it is extremely dependent on electrical energy, and the thrust generated is small, so it is only suitable for long-distance interstellar travel.

Just like the U.S. Deep Space 1 probe, it is equipped with the highest specific impulse and the longest life of the ion motor so far, its electrical energy is generated by the solar array, and the throttle stage of the thruster can be selected according to the position of the navigator to achieve the adjustment of the thrust size, so it carries a small amount of fuel, it can carry out long-distance interstellar voyages, and then a small thrust accumulates over time, in space without air resistance, it can also make the probe fly faster and faster.

However, the fact that the current plasma motor is inefficient and does not have much thrust does not mean that it does not have sufficient potential.

What if it wasn't solar panels that provided the electricity, but nuclear power?

What if the strong electric field of the plasma is electrolyzed and ejected by a factor of 10,000 or even 100,000?

With more abundant electrical energy and a more powerful electric field, will the thrust generated by the injection plasma be smaller?

Moreover, Qin Tian began to do research on controllable nuclear fusion technology a long time ago, and has accumulated a lot of technology in nuclear power miniaturization, strong electromagnetic restraint, etc., and now there are data packages provided by D1 level tasks, ready-made drawings and materials, and direct production assembly and testing.

It's just that Qin Tian never expected that the first plasma motor that was trial-produced almost led to a tragedy......
