STUDENT-HYBRID-THRUSTER TESTING AND RESEARCH

摘要

Since 2011 the Institute of Space Propulsion at DLR-Lampoldshausen offers the possibilityrnof hybrid thruster test campaigns to students. A mobile test rig was developed and the appliedrnmeasurement methods were widely extended. In many ways the hybrid thruster appears as anrnideal research object for rocket propulsion students. The thruster provides aspects of liquidrnpropulsion, phase transition, solid propulsion, ignition, combustion and rocket nozzle flow.rnSystem pressure and combustion temperature are in the order of the state of the art of rocketrnengines, but for all this the students can fully handle the thruster, rig and testing by theirrnown. The test configuration fully applies the principle of the evacuated test position whichrnmeans a complete remotely controlled test. Hence the test rig offers practically arbitrary longrntest duration. In the next student campaign the step from metallic to composite material forrnthe thruster shall be fully applied and the effect of high temperature and long duration test onrnthe thruster material will be studied.
