Similarly, if the deceleration fails and the speed is too fast, it is very likely to disintegrate and burn directly in the atmosphere, or directly hit the ground like a warhead or a meteor. Such a large arrow body, coupled with the remaining fuel in it, is very powerful when it hits it from such a high airspace at such a fast speed.
This is why he attaches so much importance to the second-stage rocket return and landing experiment and came to the site in person.
After the convoy drove off the asphalt road, it immediately started traveling through the snow-covered desert. Although the terrain next to the desert is relatively gentle, the driving speed is very slow.
On the one hand, of course, I thought it was a desert dirt road, and it was snowing, making it difficult to travel. On the other hand, there are many sharp stones in the entire desert, which can easily scratch the tires and cause accidents.
Finally, and the most important reason, because Wu Hao was in the car, his safety was the first priority, so the driver kept the speed very low.
In this regard, Wu Hao did not urge him. With this kind of weather and this kind of road conditions, it was useless for him to urge him. Besides, this was for his safety, so he very patiently chatted with Yu Chengwu in the car.
For them, such an opportunity is indeed very rare. Especially after Haoyu Aerospace went public, Yu Chengwu became even busier, and the two of them had fewer and fewer opportunities to talk alone.
Of course, if Wu Hao is willing, he can also recruit the other party, but this will also disrupt the other party's schedule and affect the other party's work. So under normal circumstances, he would not go back and disturb the other party's work. Even if there is a need for the other party to come, we will tell the other party a few days in advance so that the other party can be prepared.
Unless there is an emergency, there is no need to say anything. The other party must come immediately, and no excuses are allowed.
This experiment is very important to us. It will prepare us for the next technical demonstration and development of aerospace vehicles, so we must ensure the success of this experiment. Wu Hao said to Yu Chengwu.
After Yu Chengwu heard what he said, he nodded slightly and said: "Don't worry, we have been preparing for this experiment for such a long time, and everyone is working hard together. I believe there will be no big problems.
As for aerospace vehicles, we have also begun the preliminary theoretical and technical demonstration stage, and currently have a preliminary conceptual plan. "
oh? Hearing what Yu Chengwu said, Wu Hao couldn't help but become interested. He also wanted to know what the other party's aerospace vehicle plan looked like.
Seeing Wu Hao's interested expression, Yu Chengwu immediately introduced to Wu Hao: "Well, the concepts of aerospace vehicles or aerospace planes, orbiters, and space shuttles have been proposed for decades.
It has been forty or fifty years since mankind's first space shuttle took off. However, due to cost and high accident rate, the space shuttle has been retired one after another.
In recent years, with the development of the concept of unmanned aerospace vehicles and related technical equipment, this field has once again been taken seriously by major aerospace powers and some aerospace technology giants, and they have successively launched their own design solutions. and products.
However, at present, these are only small unmanned space orbiters, which can only carry out some earth orbit missions.
The aerospace vehicle or aerospace plane we want to develop is manned.
Contrary to other fields, in this field, manned aerospace vehicles are more technically difficult than unmanned aerospace orbiters. To put it bluntly, we are going to build a new space shuttle, but this space shuttle is different from the traditional old and bulky space shuttles. "
Having said this, Yu Chengwu licked his lips that were cracked by the wind, and then told Wu Hao with an excited expression on his face.
“As for our future aerospace vehicles, that is, aerospace planes, we plan to adopt a three-step strategy and gradually develop and advance them.
First, we are preparing to develop a light aerospace aircraft that can accommodate three to seven people to replace the current new generation of manned spacecraft and two-stage rockets.
In fact, to put it bluntly, we integrated the manned spacecraft and the two-stage rocket, and borrowed part of the design of the space shuttle to develop this brand-new aerospace plane.
During the launch phase, it needs to be combined with the first stage rocket. And depending on the mission and orbit, choose whether to bundle the booster rocket. In this regard, the first-stage rocket of our Jianmu-7 launch vehicle is very suitable. We can use these three first-stage rockets to form a first-stage rocket bundled as the aerospace plane, and use it and its own power to push it into the predetermined orbit.
Moreover, this first-stage rocket and booster rocket can also be recycled and reused, thereby greatly reducing its launch cost. Not only that, our aerospace vehicles have also replaced traditional two-stage rockets and manned spacecraft, and can also be reused, which will further reduce the cost of manning and reduce the price of sending a person into space from the current tens of millions. to millions, and eventually even down to hundreds of thousands.
And when the aerospace plane wants to land, the wings that were folded during the take-off phase will be unfolded, and then with the help of the loss-of-thrust engine, it will begin to re-enter the atmosphere, and continue to slow down by relaxing in the water. , then glide through the atmosphere, and finally land on the scheduled airport runway.
Our preliminary estimate is that if this light aerospace aircraft is successfully developed and put into use, then we will be able to reduce the current price of sending people to space by one-fifth or even one-tenth. "
Wu Hao didn't show much surprise at the number reported by Yu Chengwu, but nodded to indicate for him to continue. Yu Chengwu couldn't help but feel a little disappointed, and even more confused. Isn't Mr. Wu not satisfied with such a goal?
However, doubts turned out to be doubts, so he continued to introduce to Wu Hao: "If the development of this light aerospace aircraft goes smoothly, then we will immediately start the development of a medium-sized aerospace aircraft on this basis.
This time, we will increase the number of passengers on the medium-sized aerospace aircraft from three to seven on the light aerospace aircraft to about 20 to 35 people. This also means that we can send up to 35 people into space at one time, thereby realizing a real space flight plan and carrying out normal and continuous air and space transfer services.
Moreover, this medium-sized aerospace plane will also serve as an important carrier for us to deliver personnel and materials to the moon in the future, and will be responsible for the transfer of personnel and materials from the earth to space. "
