Abstract

The invention relates to a propellant pipeline heating support device comprising first support frame (1) and a second support frame (2) which are arranged symmetrically. The first support frame (1) comprises a first connecting part (11) and a first support part (12) which are connected sequentially. The second support frame (2) comprises a second connecting part (21) and a second support part (22) which are connected sequentially. The first support part (12) and the second support part (22) are in an arc shape. A main part heater (3) or a backup heater (5) is attached to the inner wall of the first support part (12) or the second support part (22). The propellant pipeline heating support integrated device is arranged on the outer circumference of a propellant pipeline, the pipeline is heated by the main part heater or the backup heater, and the pipeline is supported by the first support frame and the second support frame. The conflict of long-distance winding of an existing heating band and pipeline multipoint fixing is avoided, pipeline thermal control installation and a subsequent test program can be simplified, and reliability of the whole pipeline thermal control system is also improved.

Description

Technical field [0001] The invention relates to a space vehicle pipeline support device, in particular to a propellant pipeline heating support device. Background technique [0002] When a spacecraft performs a deep-space exploration mission, it faces a complicated space temperature environment. The sealed cabin environment and instruments and equipment can maintain a suitable temperature through electric heating. For space vehicles that perform manned missions, the amount of propellant filling is large, generally accounting for more than 50% of the weight of the entire vehicle. The propulsion system needs to provide force and torque for various orbit and attitude control, and the engine is installed in multiple vehicles. In terms of location, the propulsion pipeline system responsible for propellant delivery is complex, diverse and large in scale. In order to prevent the propellant in the pipeline from freezing when the temperature is too low, and to establish the necessary tem...
