Super Weapon Swap System

In principle, the spacecraft as like as two peas before, the same way of launching, and the same way of landing, using parachute to recover, but only after the final landing, it is necessary to have a recoil rocket to further reduce its speed.

What about the space shuttle? It is a separate aircraft like spacecraft. It has the ability of maneuvering flight and needs pilots to fly. Its shape is also a delta wing aircraft. As a spacecraft, it needs special personnel to develop aircraft.

Not to mention anything else, just this can embarrass many people. All present are rocket experts.

In order to develop the blizzard, Xiong Guo transferred a large number of personnel from their aircraft development department to participate in this project. What about his own side? Our side has no such ability at all.

In theory, yes, the space shuttle is a better choice. However, if our side does not have this ability, it can only give up temporarily. In contrast, the spaceship is simpler, especially when recycling, it is much less difficult to recycle only the recycling module.

"Let's continue to talk about the structure of the space shuttle in two different ways." Qin Guan said: "the eagle people's space shuttle has a main engine. If it needs to be used many times, can we guarantee the service life of the engine?"

China's aerospace technology is quite developed, but there is a gap between aviation technology and the West. What's the reason?

Spacecraft are disposable. For example, if a rocket is launched, it will be finished. As long as it meets one launch, the combustion of rocket engine is hundreds of seconds. As long as the service life of these hundreds of seconds is guaranteed.

The aircraft of aviation is different. The engine of fighter has to spend hundreds of hours if it is weak and thousands of hours if it is advanced, which requires great efforts in materials and so on.

In this way, the aviation engine is much more difficult than aerospace, which is such a situation.

The eagle space shuttle is the same as the bear space shuttle. The space shuttle has a large cylinder hanging on the side and boosters on both sides.

However, in reality, the two are actually different.

There is a fuel tank hanging outside the eagle country. The fuel tank contains thousands of tons of fuel, all of which are efficient liquid hydrogen and liquid oxygen fuel. These fuels enter the main engine under the butt of the space shuttle. After 8.5 minutes of launch, the fuel is consumed and thrown into the ocean.

In this way, the engine behind the space shuttle needs to be used many times, which brings great uncertainty. It has to be repaired every time it is used. A small problem may crash the space shuttle.

Besides, at least there is no such technology in China.

"If we want to follow the space shuttle plan, the eagle country plan is not the best." Ren said, "we plan to follow the path of the bear country. At the same time, the chicken country is the same plan."

Everyone can think of the dangers hidden in the eagle country's plan. It is very difficult to make the rocket engine burn and use for many times. Then, we need to change another way.

Xiongguo is also engaged in the space shuttle. Now it has roughly disclosed the plan. Unlike eagle, xiongguo's plan is more like launching a rocket. The space shuttle is only the load of the rocket.

The space shuttle Blizzard has only a small engine for orbit change. It is also hung on the side of a huge cylinder. This cylinder is not a fuel tank, but a real rocket.

In this way, every time it is launched, it uses an ordinary rocket. Of course, this rocket is full of power. It is an absolute super rocket, which can directly send dozens of tons of load into the earth's low earth orbit.

In this way, each launch of the rocket is one-time. The small engine on the space shuttle is only used to adjust the orbit, etc. in this way, the difficulty of the system is greatly reduced.

Not only the bear country, but also the whole ESA led by the chicken country is also engaged in the space shuttle, which was put forward in 1976.

Jiguo also wants to engage in manned spaceflight. It plans to launch a manned space shuttle by Ariane 5 carrier rocket. This is a hypersonic glider, which is simpler. It is a manned space shuttle transportation system and is named after Hermes, the mythical God.

However, it has not been seen in future generations. Due to funding problems, this project has been cancelled. Manned spaceflight can only be carried out by large countries, because only large countries can have this ability.

Qin Guan nodded: "yes, if we want to build a space shuttle, we can only take this road. However, our rockets that can undertake such a launch mission have not come out yet."

If we want to build the space shuttle, we do not have any technical reserves now. Although we are already building high thrust rockets, we still have many years to go before such rockets are successful.

"At present, the long march-2 series of launch vehicles with the highest success rate are used. These rockets have a load of nearly 10 tons in low earth orbit and can be used as the delivery vehicle of our spacecraft," Qin Guan said "This scheme has the lowest cost and the least technical difficulty. It is our most successful scheme. As for the space shuttle, why don't we take it as a long-term plan?"

Spaceships are necessary, because the route Qin Guan has set is the spaceship and the space station. The space station is a large platform of the universe, which can carry out various effective scientific experiments. The new generation of high thrust rockets developed by his side are to launch the modules of the space station.

As a space station, there must be a spacecraft on standby. Once there is a problem with the space station, withdraw from the space station and return to the earth.

Spaceship is the best plan. Look at the space station of Xiong Guo. There is a spaceship on standby outside. Generally speaking, it will be separated by half a year or even a year, depending on how long astronauts work on it.

In fact, this spaceship is the spaceship when astronauts come up. After docking, it runs together with the space station. When you go back, you can sit in this ship and go.

Of course, if the mission is normalized, the second batch of astronauts will come up, and one spaceship they bring will also be docked. Therefore, when the space station is at most, it will bring two spaceships at the same time.

Space shuttle, can it be so wasteful? Of course not!

If the space shuttle stays in outer space for a week at most, it will have to come down. Therefore, it is necessary to have a spaceship. As for the space shuttle, we will talk about it later. When the country is strong, we will demonstrate whether to launch it. Now, the spaceship is a necessary choice.
