Study of Typical Equipment Health Monitoring of Rocket Filling System

Abstract

The filling system composition were analyzed briefly from two aspects of conventional and cryogenic propellant loading system, summarize the common fault of filling system and analyses its fault characteristics, and typical equipment was selected based on the analysis of filling system. The typical equipment characteristics were analyzed, and the typical equipment health monitoring information were clear, and a good foundation of further research of typical equipment health monitoring of filling system has been laid.

The authors Published by Atlantis Press 821 the1 stage, 2 stage, and booster of rocket, Also including the transfer, storage, temperature, exhaust gas treatment and other tasks, with simulation of filling and signal joint test, small flow meter calibration functions. Dinitrogen tetroxide filling system composition in addition to storage and delivery systems and exhaust gas treatment system with unsymmetrical dimethyl hydrazine filling system is slightly different, the composition of system and the rest of the filling process are basically similar, is not mentioned here. 2.2 Cryogenic propellant loading system The cryogenic propellant loading system is mainly composed of liquid oxygen filling system, liquid hydrogen loading system and the liquid nitrogen filling system. The liquid oxygen filling system is mainly used for the adding, supplementary filling, unloading back of liquid oxygen of rocket three stage, and also for the transport, transfer, storage of liquid oxygen, and the storage tank or pipeline gas oxygen emission. Oxygen filling system can be divided to the loading control, the LOX loading fill library, liquid oxygen emission tower and pipeline according to facilities, to oxygen filling pipeline system, exhaust system, measurement and control system according to the functions. The liquid hydrogen filling system is mainly used for the adding, supplementary filling, unloading back of liquid hydrogen of rocket three stage, and also the transport and short-term storage of liquid hydrogen. The combustion of gas hydrogen of tank or pipe will be done, and the liquid hydrogen filling system have the nitrogen and helium replacement function. The liquid hydrogen filling system can be divided to hydrogen combustion control room, hydrogen fuel tank, computer room and magnetoelectric pipeline according to the facilities division; to combustion system, measurement and control system, hydrogen combustion system by burning pool and filling pipeline system according to the functions. For the convenience of intuitive understanding of the composition and work process in filling system, make gas booster type cryogenic propellant loading system as an example, a brief analysis of filling principle of filling system is done, as shown in Figure 1[2].
