Spacecraft high-temperature thermal insulation screen installation device and method

Abstract

The invention provides a spacecraft high-temperature thermal insulation screen installation device and method. The device comprises a supporting device and a lifting device. The supporting device is detachably connected with the lifting device. The supporting device comprises an upper supporting ring, reinforcing rods, a lower supporting ring and supporting legs. The upper supporting ring is connected with the lower supporting ring through the reinforcing rods. The supporting legs are connected with the reinforcing rods and / or the lower supporting ring. The upper supporting ring and the lower supporting ring are used for instlling a high-temperature thermal insulation screen. The lifting device comprises a body frame and an adjustable supporting structure. The adjustable supporting structure is arranged at the upper end of the body frame and is used for the supporting device. When the high-temperature thermal insulation screen is assembled, direct contact with an easily-abraded thermal control coating face is avoided, the operation difficulty and risk are lowered, and good effects are achieved. The spacecraft high-temperature thermal insulation screen installation device and method are simple in structure and convenient to operate, and rapid installation of the high-temperature thermal insulation screen can be achieved.

Description

technical field [0001] The invention relates to an aerospace thermal control assembly, in particular to a device and method for installing a high-temperature heat shield of a spacecraft. Background technique [0002] The high-orbit high-thrust spacecraft has entered a stage of rapid development. The high-thrust engine it is equipped with has the characteristics of large heat generation and long working hours. In order to solve the problem of high-temperature heat insulation and heat dissipation of the engine, more and more high-temperature heat shields are used Engine insulation. Unlike the ordinary medium and low temperature multi-layers of spacecraft, the high-temperature heat shield adopts multi-layer high-temperature-resistant metal materials and coatings, and has a large size and complex shape. It has the characteristics of poor flexibility and easy damage to the coating. The screen installation process requires the cooperation of multiple people, the operating space i...

Problems solved by technology

Unlike the ordinary medium and low temperature multi-layers of spacecraft, the high-temperature heat shield adopts multi-layer high-temperature-resistant metal materials and coatings, and has a large size and complex shape. It has the characteristics of poor flexibility and easy damage to the coating. The screen installation process requires the cooperation of multiple people, the operating space is narrow and the process is complicated

[0003] In order to simplify the installation process, most of the high-temperature heat shields of domestic high-thrust engines currently use integrated mounting brackets, such as Chang'e orbiter, etc., but the mounting brackets will inevitably increase the weight of the spacecraft.
