Abstract:
The noise generated during rocket engine testing is very large, and reducing its intensity is important to environmental protection. A noise reduction scheme was proposed for the testing of medium-and small-thrust liquid rocket engines, which included an ejector tube, muffler, and water spray combination, and numerical simulation research was conducted. Research has shown that the ejector not only serves as an ejector but also isolates the main jet noise source area from the environment, playing a major role in noise reduction.For small-thrust engine jets, the noise reduction effect of grid-type silencers is very good, and there is no need to add water spraying measures. For medium-thrust engine jets, the noise reduction effect of water spray is not obvious, and its main role is to cool down and reduce gas diffusion pollution. It is not suitable to use too large water spray flow and too small spray particle size. For 300 N level engines, the ejector tube carries less force, while the rear wall carries a force equivalent to the thrust. For 3 kN level engines, the ejector tube carries most of the engine's thrust, while the rear wall carries less force.
