Failure mode analysis and simulation of ascent trajectory for suborbital reusable launch vehicle

Based on frequent failures of launch vehicle and space shuttle,possible failure modes of suborbital reusable launch vehicle( SRLV) are summarized. Because of the significance of engine failure,the ascent trajectory for SRLV in the case of loss of thrust is simulated. The failure simulation system is built by theOpenFlightsimulation platform. Influences on ascent trajectory of failure are analyzed by failure simulation. The final results may provide reference for the research on abort guidance and abort capability analysis in the future.
