Thrust Characteristics of Water/Liquid Nitrogen Rocket Engine

The Blacklight Rocket Engine

Executive Summary This report summarizes the final project results for the period of May 1, 2002 through November 30, 2002 for the NIAC CP 01-02 Phase I study, "The BlackLight Rocket Engine". The objective of the Phase I study was to assess the potential of low pressure, mixed gas hydrogen plasmas (i.e. the BlackLight Process) toward the development of high performance space propulsion systems.

Adaptive Pressure Control for Use in Variable-Thrust Rocket Development

Umit Poyraz Roketsan INC., Ankara, Turkey Abstract The precise control of gas generator pressure is important to obtain variable thrust in ducted rockets. A delay resistant closed loop reference model adaptive control is proposed in this paper to address this problem. The proposed controller combines delay compensation and adaptation with improved transient response. The controller is successfu...

1. Pulsed Plasma Thruster Pulsed plasma thrusters (PPTs) are expected to be used as a thruster for a small satellite. The PPT has some features superior to other kinds of electric propulsion. It has no sealing part, simple structure and high reliability, which are benefits of using a solid propellant, mainly Teflon (poly-tetrafluoroethylene: PTFE). However, performances of PPTs are generally lo...
