In cooperation with the serial NSPO sounding rocket programs and application of the research results of the Institute of Aeronautics and Astronautics, National Cheng Kung University in the current proposal, we propose a series of Indigenous Propulsion Experiment payload Onboard Sounding Rockets, including: hydrazine monopropellant, hydrogen peroxide monopropellant, micro-propulsion and bipropellant subsystem. In the first stage of this multiple-year project, in two years (2005/4/1~2006/12/31) with two phases (phase I: 2005/1/1~2005/6/30 and phase II: 2005/7/1~2006/12/31) we will be compliant with the NSPO sounding rocket launch schedule of 2006 and develop the hydrazine thruster system onboard the sounding rocket as the payload to verify the key techniques and the thruster system developed.
