Cryogenic propellant on-orbit thermal protection device and design method thereof, and spacecraft

Abstract

The invention discloses a cryogenic propellant on-orbit thermal protection device and a design method thereof, and a spacecraft. The cryogenic propellant on-orbit thermal protection device is as follows: a protection device is arranged above a storage box; the protection device comprises a first support arranged on the storage box, a protective cover for blocking solar radiation is arranged at thetop of the first support, and the protective cover is made of a thermal insulation material. The solar radiation is sheltered by arranging the protective cover; furthermore, the cosmic space is usedas the cooling environment; the solar radiation energy absorbed by the protective cover dissipates heat to the external in a thermal radiation way, thereby realizing the on-orbit zero-evaporation storage of the propellant; the problem that the on-orbit zero-evaporation storage of the propellant cannot be reached by the existing passive protection thermal insulation material is solved, the storageefficiency and the security of the storage box are greatly improved, and the application range of the cryogenic propellant is more extensive. The invention further provides a design method of the cryogenic propellant on-orbit thermal protection device. And the invention further provides a spacecraft containing the cryogenic propellant on-orbit thermal protection device.

Description

technical field [0001] The invention relates to the fields of manned spaceflight and deep space exploration, in particular to a low-temperature propellant on-orbit thermal protection device and a design method thereof. In addition, the present invention also relates to a spacecraft comprising the above-mentioned low-temperature propellant on-orbit heat protection device. Background technique [0002] Future exploration missions will use more and more low-temperature propellants. If the goal of zero-evaporation storage of low-temperature propellants can be achieved, the storage efficiency and safety of the storage tank will be greatly improved, and the application range of low-temperature propellants will be wider. , increase the flight distance of the spacecraft of the same quality level, and greatly save costs. [0003] There are two main methods of traditional cryogenic propellant on-orbit storage heat protection schemes: passive heat insulation protection and active cool...
