Chapter 460 (1/2)

Although the No. 3 aircraft was hit by meteorites when it entered space, fortunately, there was no problem when it re entered the atmosphere and successfully entered the landing state.

Soon, at about one o'clock in the afternoon, Wang Bin and others finally saw the three returned spaceplanes. Seeing that the three planes, especially the astronauts, were safe, Wang Bin and others were completely relieved.

So Wang Bin and his team, after the three spaceplanes landed one after another, Wang Bin and the technicians of Tiangong technology hurried to the runway. Of course, the first to arrive at the three planes was naturally the shuttle car for astronauts. After all, these astronauts will be sent to a special place immediately after landing, Carry out disinfection and sterilization.

Then, other vehicles dedicated to cooling and cleaning these aircraft came to the scene and cooled them. Finally, when all these were completed, Wang Bin and others came to the side of the aircraft and began a preliminary inspection of the three aircraft.

I don't know if I didn't check it. Once I checked it, Wang Bin and the technicians of Tiangong technology were really surprised. After inspection, Wang Bin found that the air and space test flight was actually very dangerous. In the whole fleet, in fact, not only one aircraft No. 3 was hit by meteorites.

In addition to aircraft No. 3, in fact, aircraft No. 1 and No. 2 were also impacted by meteorites, and there was more than one impact point. According to the meteorite debris posted on the aircraft's thermal insulation glass, there were basically three or five traces on each aerospace aircraft.

In other words, in the course of this test flight, except for the impact point on plane 3, several other planes were hit by meteorites many times.

This makes everyone present sweat. If these meteorites are a little bigger, if these aircraft don't have special glass insulation, then the consequences

However, fortunately, except that the impact meteorite at the cargo warehouse of aircraft No. 3 was relatively large, causing a piece of thermal insulation glass rupture and aircraft skin depression for the aircraft, other meteorites were obviously small in volume, so they did not break through and damage the special glass thermal insulation layer of the aircraft, nor did they cause any damage to the aircraft skin.

It can be seen from here that the defense capability of these aerospace aircraft of Tiangong technology is still very excellent.

After all, if this happens to other spacecraft, even large rockets, after such a strong impact, it is very likely to cause the failure of rocket launch and the damage of spacecraft.

Therefore, when everyone present saw the wreckage on these planes, they all took a breath. At the same time, they also felt very lucky, especially for the requirements put forward by Wang Bin when designing this aircraft.

You know, at the beginning, when they designed the aircraft by Tiangong technology, many designers and technicians proposed in Wang Bin that it was necessary to install heat insulation modules outside the aircraft skin, just like tanks with additional armor, but they didn't understand it.

After all, according to the calculation of technicians, the aircraft has a very strong high temperature resistance even without the thermal insulation glass panel module. After all, the space alloy steel used in the aircraft skin has a very high heat resistance. It is absolutely unnecessary to add an additional thermal insulation layer on the outside of the aircraft.

And doing so will greatly increase the overall weight of the aircraft, so that the carrying capacity of the aerospace aircraft with very limited glass carrying capacity will decline again.
