Vol 4 Chapter 2355: Aerospace plane "3-step" plan

Similarly, if the deceleration fails and the speed is too fast, then it is 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, plus the remaining fuel in it, smashed down from such a high airspace at such a fast speed, its power is very terrifying.
This is also the reason why he attached so much importance to the return of the second-stage rocket to the landing experiment and came to the scene in person.
After the convoy pulled out of the asphalt road, it immediately traveled through the snowy desert. Although the terrain next to the desert is relatively flat, the speed of the car 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 next to the desert, which can easily scratch the tires and cause accidents.
In the end, it was the most important reason, because Wu Hao was in the car, and his safety was the first priority, so the driver kept the speed very low.
Regarding this, Wu Hao did not urge him either. It was useless for him to urge in this weather and road conditions. Besides, this was also for his safety, so he 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 there were fewer and fewer opportunities for the two to get along and 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. Therefore, under normal circumstances, he does not go back to disturb the other party's work. Even if it is necessary for the other party to come, it will be said a few days in advance so that the other party can be prepared.
Unless there is an emergency, there is nothing to say, the other party must come immediately, and no excuses are allowed.
This experiment is very important to us, which will prepare for the technical demonstration and development of our next aerospace vehicle, so we must ensure the success of this experiment. Wu Hao said to Yu Chengwu.
After Yu Chengwu heard his words, he nodded slightly and said: "Don't worry, we have been preparing for this experiment for so long, and everyone is working hard together, I believe there will be no major problems.
As for the aerospace vehicle, we have also started the preliminary theoretical and technical demonstration stage, and we have already had a preliminary conception plan. "
Oh? Hearing what Yu Chengwu said, Wu Hao couldn't help being interested. He also wanted to know what the other party's aerospace vehicle plan was like.
Seeing Wu Hao's expression of interest, Yu Chengwu immediately introduced to Wu Hao: "It's like this, the concept of aerospace vehicles or aerospace planes, orbiters, and space shuttles has been proposed for decades.
It has been 40 to 50 years since the first human space shuttle took off, but due to the 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 valued by major aerospace powers and some aerospace technology giants, and has successively launched their own design solutions and products.
It's just that, at present, these are just some small unmanned space orbiters, which can only carry out some ground-orbit missions.
And the aerospace vehicle or aerospace plane we are going 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 not the same as the traditional, old and bulky space shuttles. "
Having said that, Yu Chengwu licked his lips that were blown by the wind, and then told Wu Hao with an excited expression on his face.
"As for our future aerospace vehicle, that is, the aerospace plane, we intend to adopt a three-step strategy and gradually develop it.
First of all, we are going to develop a light aerospace aircraft that can accommodate three to seven people, which can be used to replace the current new generation of manned spacecraft and secondary rockets.
In fact, to put it bluntly, we have combined the manned spacecraft and the secondary rocket, and borrowed some 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 of the rocket. And according to the mission and orbit, choose whether to bundle the booster rocket. In this regard, the first-stage rocket of our Jianmu-7 carrier rocket is very suitable. We can use such three first-stage rockets to form a bundle as the first-stage rocket of 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 vehicle has also replaced traditional secondary rockets and manned spaceships, and can also be reused, which will further reduce the cost of manned people, and reduce the price of sending a person into space from the current tens of millions. To millions, and even eventually to the level of hundreds of thousands.
And when the aerospace plane wants to land, its folded wings during takeoff will unfold, and then with the help of a loss-of-mass thrust engine, it will begin to re-enter the atmosphere. Relax, slow down, glide through the atmosphere, and land on the intended runway.
Our preliminary estimate is that if this light aerospace plane is successfully developed and put into use, then we will be able to lower the current price of sending people to space by one-fifth, or even one-tenth. "
Regarding the figure reported by Yu Chengwu, Wu Hao did not show much surprise, but nodded to signal him to continue. Yu Chengwu couldn't help feeling a little disappointed and even more puzzled about this. Isn't Mr. Wu still satisfied with such a goal?
But doubts turned into doubts, he continued to introduce to Wu Hao: "If the development of this light aerospace aircraft is successful, then we will immediately start the development of medium aerospace aircraft on this basis.
This time, we will increase the number of passengers on the medium aerospace plane from the three to seven people on the light aerospace plane to about 20 to 35 people. This also means that we can send up to 35 people into space at one time, so as to realize the real space flight plan and carry out the normal continuous air and space transfer business.
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 undertake the transfer of personnel and materials from the earth to the space segment. "
