“So how to save fuel and increase transportation load has become the focus of our scientists’ research, and everyone has proposed various solutions.

Among them is the parachute deceleration technology used on our traditional spacecraft and our Jianmu-2A launch vehicle.

The parachute is used to decelerate the aircraft when it returns to the atmosphere and lands, thereby greatly saving the fuel consumption of the engine for reverse thrust deceleration. In this way, a large amount of fuel costs can be saved and the transport load of the aircraft can be increased.

But this will also bring about a new problem, that is, this kind of aircraft is generally relatively heavy. If a parachute is used, a very huge parachute bag is required, so there are higher requirements for the material strength of the parachute. In addition, this kind of parachute bag itself will also occupy a certain amount of load space including transportation load, so it is also a waste.

Finally, if you use a parachute to land, the airflow will have a huge impact on the landing accuracy, so this aircraft cannot land accurately on the preset landing field.

So in the end we set our sights on the space shuttle. During the process of returning to the atmosphere and landing, the space shuttle can glide in the atmosphere relying on the lift generated by its wings, thereby greatly reducing fuel consumption and thus saving money. Lower costs.

Moreover, the landing point of the space shuttle only needs one runway, so there is no search and recovery process, which can greatly reduce the work and cost of search and recovery.

However, it is not that the maneuverability of the space shuttle is relatively weak and it cannot achieve slow-speed continuous launch, but that it takes a long time to prepare like other methods.

First of all, it is not because the space shuttle has no successful cases and cannot be used for reference, so the related development difficulty cannot be reduced.

So you determined the main development direction, and developed this small-purpose orbiter into a new space-to-space shuttle vehicle, or a space shuttle.

If everything goes well, it will probably be very slow, but if the technical problems can be overcome, then the development progress and time will have to be extended by a certain date.

Secondly, because the cabin space is relatively small, the facilities and equipment are relatively complete. For example, it is not possible to install a toilet that traditional manned spacecraft cannot have, thus solving the astronauts' urgent need.

It cannot carry more than seventeen or even seventy people to and from space at one time, so its personnel carrying capacity has been slightly improved.

So what you are more curious about now is, to what stage has the development of their small-purpose orbiter reached, and when will it take off for the first time? "

Indeed, upon hearing that, Qin Xinghe nodded in agreement. The word "space shuttle" is indeed very sensitive, and it is difficult to attract other people's attention. After all, for a long time outside, the space shuttle was a symbol of Laomi's space hegemony. So if Peng Mao and we use that word, it will be difficult for other people to have some necessary associations, and there may even be some people who are hostile to you and those who have no intentions to use it to hype it up.

Forehead…

After explaining that point, Peng Mao continued: "Although the development cost and unit price production cost of that small-purpose orbiter are more expensive than special launch vehicles and manned cargo spacecraft, the advantage is that it cannot be reused. Therefore, it is evenly allocated to each cost
