Hybrid Rocket Propulsion Technology for Sounding Rocket Development

Hybrid combustion technology has recently been employed in the sounding rocket developments to support the science experiments of academic applications and the establishment of a viable flight test platform for space components development. Due to its safety nature in material handling and combustion processes, hybrid rockets are suitable for university and research institute environments for a...

Machine Learning for Rocket Propulsion Health Monitoring

This paper describes the initial results of applying two machine-learning-based unsupervised anomaly detection algorithms, Orca and GritBot, to data from two rocket propulsion testbeds. The first testbed uses historical data from the Space Shuttle Main Engine. The second testbed uses data from an experimental rocket engine test stand located at NASA Stennis Space Center. The paper describes fou...

مروری بر روش‌های مطالعه ترک در مواد پلیمری پرانرژی

Cracking is the breaking of bonds in a part of the propellant polymer due to the existing stresses that change the structure of the propellant polymer and they are classified into two general categories: macrocrack and microcrack. The service life of rocket engines is largely a function of the mechanical properties of the solid rocket propellant, the aging characteristics of the rocket propulsi...
