Chapter 497

If the rocket can not be launched on time, it will be delayed to wait for the next launch window, or even delayed for one or several days. Therefore, "zero window" launch puts forward higher requirements for rocket reliability.

Take China's Chang'e series launch as an example. The launch window of "Chang'e-1" is reserved for 35 minutes, and it can be launched within these 35 minutes.

However, compared with the launch in the first minute, the last minute will lose 120 kg of fuel, which will directly affect its working time and service life.

If, due to special reasons, the launch can not be carried out normally within these 35 minutes, the launch plan can only be cancelled and the launch window will be re determined in the next year.

The launch of Chang'e-2 in the "zero window" will save 180 kg of fuel and prolong the on orbit test time.

With such a big gap, it's no wonder that Zhang hanxiu is so nervous. If all the payloads can be launched in the "zero window", then their work will be in place.

This is also the reason why they always run to the meteorological monitoring laboratory recently, because the rocket launch may be delayed due to technical problems, the rest of the reasons can be linked to the weather.

Although the company has also recruited a lot of meteorological experts and purchased and manufactured a lot of meteorological monitoring equipment, its experience is still comparable to that of the National Space Department with rich rocket launching experience.

Therefore, the group company invited partners to help the meteorological experts of these companies master the meteorological monitoring of rocket launching.

And cooperation with the national team, is Lei Tiantang's own policy, but also in the company's meeting was approved by all.

If you would have thought it was a little inconceivable before, with the company's step-by-step space planning down, people in the company began to believe that the boss's spaceship plan was really possible to succeed!

With huge financial support, more and more top scientists and researchers, and clear development plan, people of the company feel that in the next 20 years at most, the group company will be able to initially master the manufacturing technology of solar system spacecraft!

At that time, we need to launch satellites, space telescopes, space stations and other payloads. As long as they are loaded into the cargo ship of the spaceship, it will be good to directly use the spacecraft to pull them from the ground to space.

That is to say, no matter how advanced the technology is, Rockets will be eliminated! Even the heavy launch vehicle being developed by the infinite gravitation group will not be needed by then!

Because according to the company's heavy launch vehicle research and development standards, the maximum weight of the low earth orbit can reach 200 tons, and the escape orbit can reach 70 tons.

Even if all countries and companies in the world want to achieve this standard, it will take a long time to achieve this standard. It can be said that after the research and development is completed, the rocket technology of infinite gravity group will be the world's best.

Although this kind of carrying capacity seems to be a lot, it can also meet the construction of the space station and the mission requirements for launching various detectors in the solar system, but it is much worse than the spacecraft!

Because even according to the minimum standard, the design standard of the company's first generation spacecraft should exceed this number!

The use of nuclear fusion reactor as energy can make the spaceship have an inexhaustible energy, and the minimum load of the spacecraft can also exceed 1000 tons. This load is still the minimum standard.

The maximum load should at least exceed 3000 tons, and only such a large load can satisfy the company to start mining on the moon and Mars in the future.

To meet the company's initial construction work of space colonization on the moon and Mars, after all, there were too many materials to be transported to these colonies at that time.

If you use a rocket to launch slowly, even Lei Tiantang can't afford the cost of such a launch. Even if the company's heavy rocket can increase the escape load to 100 tons, there is no effect.

If you want to build a colony that can let people live for a long time, at least you need to pull tens of thousands of tons of materials from the earth!

At that time, the group company launched rockets into space every day? Otherwise, when will so many materials be transported?

Not to mention that it is impossible for the company to build a colonial base on such a large moon and Mars. Even if it is in accordance with the minimum requirements, it should at least build more than 10 bases.

Mineral rich areas of course, we must first ring up the land, otherwise we have to wait for other countries and companies to occupy these places!

If hundreds of thousands of tons of materials want to be launched by rocket, the group company has to launch more than 5000 times at least! What is this concept?

Even if you launch five full loaded rockets every day, it will take nearly three years to launch!

The 5000 rockets alone are a huge expense. Even if the group company designs recyclable rockets, it will take at least 200 rockets to meet the launch needs!The rocket is made by the company itself, so the company can afford to spend money, but the cost of supporting various projects is fierce!

The allocation of various materials and the wages of various personnel are all long-term expenses that need to be paid in a long-term way. At least tens of billions of dollars should be paid every year in this respect!

Moreover, every launch is a challenge. Even if the technology is more mature, various uncertain factors will lead to launch errors.

These mistakes will delay the launch speed, and the lost materials need to be prepared again. There are also various bad weather effects, such as typhoons, lightning and other weather can not be launched.

Therefore, it is impossible to launch rockets into space every day. In this way, the construction speed of the colony will not be guaranteed. The company may be delayed to normal development by such construction projects.

So rocket launching is a technology that is doomed to be eliminated. If the company takes it out to cooperate with the country, no one disagrees.

A spaceship can launch more than 30 times at least with a cargo, not to mention the advantages of safety and so on.

Who will use the rocket to make the best use of them!

Anyway, people in the company don't feel that they can't finish the company's plan now. They just build spaceships. Roll up their sleeves and work hard. They will succeed in the near future!
