TEST BENCH FOR ELECTRODELESS PLASMA JET ENGINES Russian patent published in 2025 - IPC G01M15/14 

FIELD: testing.

SUBSTANCE: invention relates to test benches for rocket engines and can be used to study technical characteristics of prototypes of electrodeless plasma jet engines (EPJE). Test bench represents a vacuum chamber hermetically separated by a diaphragm into two compartments: the main one and the engine compartment. Engine compartment can accommodate EPJE and auxiliary equipment. Main compartment is designed to simulate an airless space. Test bench comprises pumping system. Engine compartment is located on movable platform with electromechanical drive with possibility of moving away from the main compartment. Said diaphragm can be locked both on engine compartment and on main compartment. Diaphragm can withstand pressure drop of 10⁵ Pa. Engine compartment comprises a telescopic mechanism for moving the EPJE. On the movable platform there is also a control system of the EPJE and forevacuum pumps. In the main compartment there is a telescopic mechanism for moving diagnostics with servo drives, which moves along the axis of the main compartment. On the telescopic mechanism for moving diagnostics there are two tables for diagnostics, wherein one of the tables can additionally move along the radius of the main compartment. For replacement of heavy diagnostics engine compartment together with diaphragm moves away from the main chamber, and telescopic mechanism of diagnostics movement brings tables with diagnostics outside the main chamber into sub-crane zone.

EFFECT: wider range of test benches for electrodeless plasma jet engines.
