The high-pressure gas cylinder is the pressure source for liquid propellant engine valve control. Leakage a significant cause of loss in cylinders, leading to control failure and serious flight accidents. In this paper, model-based approach estimate leakage area remaining useful life (RUL) cylinders proposed. To area, state space representation system developed based on nonlinear model derived ...

Abstract This paper investigates iodine as an alternative propellant for space plasma propulsion. Measurements are taken in a low-pressure inductively-coupled chamber used the ionization stage of gridded ion-engine. Langmuir probes to measure electron density and energy distribution functions spatial variations between inductive coil extraction grids several radio-frequency (RF) powers mass flo...

for a long time, many efforts have been taken on improving gas turbine performance to increase the propulsive force and keep the chamber walls cool. in this regard, implementation of cyclonic and vortex engines have been proposed. according to increasing in the engine efficiency and keeping the chamber walls cool, the bidirectional vortex flow which is exited in the vortex engine, makes researc...
