Abstract:
The automatic emergency cut-off system is the key link for test of the rocket propulsion system, and is the powerful safty guarantee of the system and test bed. According to the characteristics and the response needs of LOX/kerosene propulsion system in hot firing test, the VXI-based data acquisition system and emergency cut-off system were developed. The cut-off discrimination software based on VC++ was designed according to the functional requirement. Firstly, the basic functional module is designed, including data acquisition, warning, real-time storage, image display. Secondly, the implement scheme of cut-off discrimination software based on VC++ is explained in detail, including software application environment and flow of core-program. The main interface of application is shown. The key factors which influence the timing response of automatic cut-off are analyzed. The software's functions and failure detection ability were tested by means of more than one hundred simulated data. The maturity of the software functions and acceptable performance were validated in the hot firing test.
