This review paper reports various concepts of the gun propulsion system to meet the goal of the futuristic hypervelocity projectiles. The nonconventional concepts, such as liquid gun propellant, rail gun, coil gun, electrothermal gun, electrothermal chemical gun along with conventional energetic solid gun propellant have been discussed. Even though muzzle velocity around 2000 m/s has been claim...

This paper describes the design of a power supply and actuation system appropriate for position or force controlled human-scale robots. The proposed approach utilizes a liquid monopropellant to generate hot gas, which is utilized to power a pneumatic-type actuation system. A prototype of the actuation system is described, and closed-loop tracking data are shown, which demonstrate good motion co...

Proposed crewed and robotic exploration activities demand that high-performance, cryogenically fueled, in-space stages perform high delta-V missions that range from days to months in duration. In 2011 ULA presented a concept for the integration of in-space tank pressurization/vent, power-generation, attitude control and vehicle propellant settling functions into a single system based on the uti...


 An approach has been developed to the formation of a theoretical model movement gas- saturated liquid in flow path porous centrifugal pump, as an assembly system for feeding reaction mass liquid-propellant rocket engines. The is based on physical turbulent motion gas-liquid mixture, within which conservation equations are used. Two models proposed that describe mixture pump two-phase one...
