Mono-Propellant Warm Gas Pressurization with Dual Use for Attitude Control System

Systima Technologies, Inc. is proposing an innovative self-pressurizing monopropellant supply system that eliminates the need for high-pressure propellant tanks and is capable of providing a constant pressure supply of propellant to conventional or multi-mode, monopropellant-based, propulsion systems.  Because the concept does not require high-pressure propellant tanks, the propellant tank weight can be minimized, resulting in significant weight savings.  In addition, since the propellant is not stored under high pressure, the propellant tanks can be shaped to the available space, not unlike the fuel tank in an automobile, dramatically increasing the packaging efficiency of the propellant tanks and reducing the overall size of the propulsion system. BENEFITS: The primary benefit expected from the Phase I and II programs is the design and development of a monopropellant supply system that is capable of providing a constant pressure supply of propellant to conventional and multi-mode propulsion systems and that is more compact and lower weight than conventional pressurization systems.  These attributes will make the technology attractive to manufacturers of satellites and satellite propulsion systems.
