Chapter 1766

Laser weapons are beautiful to say and difficult to realize. Like electromagnetic catapults, it is difficult to mature. That thing is almost as powerful as a laser rangefinder. What power does it take to burn through the enemy directly? The nuclear explosion is similar to the generator.

Qin Guan didn't hide it on purpose. When they inspected their own laser tanks, they knew that this thing was not killing people, but destroying the enemy's observation and aiming equipment.

At that time, they will be disappointed and serious. After all, their own side did not deceive them. Now it is that level.

How can our own lasers be more powerful than their eagle and bear countries? Our side has only made progress in some aspects.

Qin Guan ended his visit to Hughes company and stayed in a nearby hotel with the team. Everyone began to discuss the next plan.

"Hughes company is the largest aircraft company. In addition to Hughes company, there are many other companies that develop satellites. We can go around more, investigate and find new potential customers." Wang said: "in fact, McDonnell Douglas also produces satellites."

Almost all aviation enterprises have investment in aerospace and general dynamics, and they are also developing satellites. Eagle country has a strong scientific research level. Here, China needs multiple teams to tackle key technical problems and jointly develop a project. Eagle country is a lot of companies, each of which can compete with each other.

McDonnell Douglas? Qin Guan felt that his eyes were high and his hands were low. After reading so much, he forgot the nearest one around him!

It's hard to say. We'll go to McDonnell Douglas tomorrow. They are all old owners. It's easy for everyone to communicate.

"We have gained a lot today," Wang continued. "We can find that satellites in the world have begun to develop in two directions."

China has been making cars behind closed doors. So far, it has just realized geosynchronous communication satellite. Looking at the west, people have taken great strides forward. This time, they are deeply touched.

"On the one hand, the satellite communication capacity is increasing day by day and developing towards heavy satellites. For example, the HS-601 of Hughes company weighs 3.6 tons, which was almost unimaginable in the past. The same satellite weighs more and more and the cost is higher and higher, but it still has the highest cost-effectiveness ratio, which is better than two satellites. On the other hand, it is moving towards single function and low cost Cost small satellite development. "

These two trends are not contradictory. For some satellites, the bigger the better. For some satellites, as long as they have simple functions, small satellites can do it.

For example, with the development of technology, the circuits on the reconnaissance satellite are becoming smaller and smaller, and the lens is becoming smaller and smaller. In this way, the satellite does not need to be so large. The original volume and weight of a satellite can now be four or five, which can increase the scope of investigation, which is much better than the original large satellite.

So? Qin Guan looked at Old Wang and knew that he still had something to say.

"Therefore, we thank President Qin. The technical route given by President Qin is correct. The carrying capacity of the new generation of rockets we are developing has been greatly improved. In the future, we can launch heavy satellites with a new generation of rockets."

The technical route given by Qin Guan is to develop a larger core stage rocket, using a liquid oxygen kerosene engine, which can be put into orbit directly with a monopole, or a one-and-a-half stage. Now such a rocket has begun intensive research and development. In the future, there will be more heavy launch needs in the international market, and our own side can also meet them.

There are heavy satellites. What about light satellites?

It is not cost-effective to launch light small satellites with existing rockets, and this need has begun to appear in the international market.

"What about the small satellite?" Qin Guan said to old Wang.

With a smile on his face, Mr. Wang said, "Mr. Qin, I still need your guidance in this regard."

Qin Guan was stunned. He pointed to the liquid oxygen kerosene engine and the new generation of rockets because he knew the history. If he wanted to realize manned spaceflight and space station, he had to use high thrust rockets. However, if he said small satellites, he really didn't think about it.

In those days, the white elephant country launched 104 satellites in one breath, and then publicized how advanced its technology was. In China, it was only five stars with one arrow at most.

Yes, launching a small satellite can shoot many stars with one arrow.

"We can launch small satellites with one arrow and many satellites." Qin Guan said, "a single satellite has a small mass, but we can carry several more satellites and launch them together. Of course, it requires our orbit change ability in outer space. I believe it is not difficult for us."

With an advanced computer system, it's easy to calculate the orbit. Qin Guan said that Wang agreed: "yes, I think so. We can launch with existing rockets. It's still profitable to launch several more at a time, but it can't last long."

This technology can be used, but it may not happen. What if there is only one customer? The second customer can't wait. Is this customer worried? What shall I do?

It's best to have a special rocket to launch. What kind of rocket can?

"Solid rocket!" at this time, Qin Guan had thought of it.

Long march series launch vehicles are a big family in future generations. From the Long March 1 to the Long March 11.

One of them, the Long March 11, is dedicated to this work.

The biggest feature of solid rockets is convenience. They are the same as ballistic missiles. In the past, they were liquid missiles. How long do you have to prepare for one launch? Just adding fuel is a headache, but solid missiles are not. They can fight when they are supported!

Ballistic missiles and rockets come down in one continuous line. The Long March 2 rocket comes from dongfeng-5, and now Dongfeng 21 is mature and Dongfeng 31 is under development. It is also possible to develop a solid launch vehicle on the basis of these missiles.

The specific impulse of solid rocket is high, but the thrust is small, and it is the most appropriate choice to launch a small satellite!

"Mr. Qin, your idea is very good." Mr. Wang suddenly understood: "if we want to use solid rockets, we need at least four-stage rockets to complete the launch task. After we go back, we can conduct preliminary research first!"

Four stage rockets, so many?
