The summer standard of the Rockets

Continuous high -temperature red warning, 40 degrees Celsius cannot enter the top ten of the national high temperature rankings ... Although it has been autumn, the "heat" in summer has not retreated.

In hot weather, many people are in the room, and the air conditioners are standard; when they go out, sunscreen, sunscreen, and parasols are standard.

High temperature is also a challenge for the Rockets. What is its summer standard?

Rockets also wear "sunscreen"

Many people like to wear white clothes in the summer because white does not absorb heat. If you have observed, you will find that the rocket arrow body is basically white. This is because white can reflect light calories, which is conducive to the cooling of the arrow body.

Having said that, we have to mention a new generation of carrier rockets that perform launch mission at Wenchang's launcher. Hainan is basically hot and humid in summer, and the sunshine intensity is about 1.6 times that of Beijing. The new -generation carrier rocket uses a hydrogen hydrogen oxygen ultra -low -temperature pushing agent. After adding fuel at the launch site, the inside and outside of the rocket is "two days of ice and fire". In order to highly heat insulation, the surface temperature of the rocket needs to be reduced.

To this end, the Institute of Aerospace Materials and Crafts of the Rocket Academy specifically made a "sunscreen" for the new generation of carrier rockets, which can not only prevent hydrosis, saline fog, mold -proof, and anti -static.

After testing, the "sunscreen" of the new generation of carrier rockets has good sunscreen effects. Even if the Rockets shine in the sun for 2 years, they will not turn yellow or aging. In addition, in the 240 -hour damp heat alternation, "sunscreen" can not be bubble, cracking, and not sticking.

Rockets also have air -conditioned rooms

In summer, everyone wants to hide in the air -conditioned room. Before the transition, the Rockets must complete many tasks such as the testing and installation of the installation and testing plant, the test and installation of the unit instrument on the arrow, and the system testing, matching inspection, and full arrow inspection. The air conditioner will keep the spacious and bright assembly testing plant at a suitable temperature, and the Rockets can comfortably complete the "big transformation" here comfortably.

It is worth mentioning that the difference between the Long March No. 2 F -Car Rocket Station Plant. Starting from the Long March 2 FD 12 carrying the Rockets and the Long March No. 2 Far Remain 13 Lairer, the Rockets adopt a new launch mode of "launching one hair, backup one" and "rolling backup". The Long March 2 FD 14 Rockets that completed the launch task in June this year. From August 17, 2021, "Hanging up and vertical", plus the launch preparation time, the erection time is nearly 10 months. During this period, it experienced a summer. When the desert Gobi was high, it could reach more than 40 degrees Celsius when the temperature was high. In order to make it more comfortable, the temperature and humidity of the rocket's plant is strictly controlled, neither high nor low.

Rockets also have mobile cooling equipment

When you go out in summer, will you bring a portable fan to send yourself cool at any time? When encountering hot weather, scientific researchers will also equip the rocket with mobile cooling equipment, so that the Rockets will be in an environment with a suitable temperature.

In order to ensure that the effective load in the rectifier and other precision meta components before the rocket was launched is normal, the air in the rectifier cabin must maintain a certain temperature and humidity and cleanliness. The designer of the Rocket Institute's overall design department, Qian Hang, was introduced on July 24th Long March 5 Lotor Rockets Launch Questioning Tiangan Experimental Currency as an example. Asked about the world's largest load in the world, it is also the most in the third cabin section of the space station. The biggest and largest one. In order to accommodate the "passenger", the team deliberately customized the oversized rectifier with dry room temperature and air -conditioning air supply.

The fuel in the "belly" of the Long March 5 B -carrier rocket is the ultra -low temperature liquid hydrogen oxygen, and the launch window is the next day. Before performing the launch mission, the Long March 5 B -carrier Rockets must be transferred from the assembly plant to the launch tower. It takes two or three hours to complete the whole process.

In order to prevent the "ice arrow" and "heat stroke", Qianhang said that the designer set up a "cold chain transportation", that is, during the process of transsing and rocket transfer to the launch area, all the air conditioners were transported to the cover. Air, guarantee the comfort of the test compartment. Among them, the star cover combination is mainly used by the hair dryer equipment equipped with the transshipment vehicle. The rocket transfer to the air conditioner on the launch platform during the launch area. After the rocket reaches the launch area, the rectifier part is air -conditioned through the air conditioning port, and the air conditioning air conditioning is performed through the cabin section.

The aerospace industry is extremely complicated system engineering. In the cold and summer, the Rocket Academy's reliability and safety of the Rockets are full of hard work, and it deserves "hot" love.
