Abstract

Tests are described and analyzed for a thrust module of knocking combustion pulsejet engine. This advanced engine was tested on a special experimental bench. An operation of the thrust module investigated with the bench is based on the Hartmann-Sprenger effect. High-frequency self-oscillation arise within the thrust module resonator shaped as a segment of sphere for some combinations of geometrical and gas-dynamical parameters of the resonator. Reasonable geometrical and gas-dynamical parameters of the thrust module are determined for forthcoming tests with ejector thrust enhancer for the non-steady pulsating stream case.
