Abstract
The improved pulsatory turbo shaft engine consists of three assemblies, including one independently running air compressor assembly, one compressed air storing assembly and one mixed gas burning work doing assembly. The air compressor assembly comprising coaxially cascade axial air compressors and centrifugal air compressors is driven by one motor or one turbine combination to produce compressed air to be stored in the compressed air storing bin. Under the control of the air distributing device, compressed air is mixed with fuel inside the combustion chamber to burn, and the heat energy acts directly onto the turbine combination, so that the turbine combination rotates in the controlled direction and rotation speed to output kinetic energy. The engine under the control of the air distributing device runs in the cyclic pulsation mode of 'intake-burning to do work', and has comprehensive performance superior to available gas burning engines.
