MAI engineer works on reducing noise and vibration in engines and pumps
"Vibration destroys the engine. Normally, liquid rocket engines burn up in the atmosphere as it is, but today the issue of reusing them has become relevant," says Dimitri. "This can be achieved by reducing vibration. The impellers are equipped with additional smaller blades. My team has developed a methodology that will help you find the optimum shape for a particular wheel."The methodology being developed by the MAI researcher will help in the design process providing practical advice on how to select the optimum size and shape of the undercut blade (called splitter) of a double-deck wheel in the pump, as well as its position in relation to the main blades of the wheel. This will reduce noise at the vane frequency and increase the life of the pump.The developments will be applicable to any pumping installation, including summer houses, residences and institutions.
