After the successful launch of the spacecraft, it can detect various space objects for humans, and the cost of the spacecraft during operation is quite high. Recently, scientists have said that the development of a spacecraft heat shield is beneficial in terms of cost savings. recovery tasks.

Currently, high-temperature heat shields are used to protect the exterior of the spacecraft. These devices are made of solid materials. Recently, NASA has successfully developed a new heat shield with rotating technology, and this invention will greatly reduce the quality of the spacecraft itself. If you want to successfully land a spacecraft on other planets, then the spacecraft must have a heat shield. universities have developed a new type of heat shield that is simpler, lighter and cheaper to manufacture.

When a spacecraft falls into a planet's atmosphere, the air will generate a lot of heat through friction against the spacecraft, and for heat shields, their biggest function is to dissipate heat, thus lowering the temperature of the spacecraft itself. . In addition, it can reduce the spacecraft's flight speed by creating aerodynamic drag. Heat shields in use today also include mechanically deployable shields, and they created a different prototype that uses a flexible, heat-resistant material that folds freely when not in use. spaceship.

As the heat shield rotates, centrifugal force will cause its sides to open and solidify, which will create a lot of drag and slow down the spacecraft's descent rate. In addition, its heat dissipation protection function In order to protect the spacecraft from damage, this prototype is relatively light, small and flexible, and can be applied to small satellites, so its research value is also promising. In addition to the above benefits, developing it can also save you a lot on recovery tasks.
