Sliding-blade heat engine with vortex combustion chamber

Abstract

A sliding-blade heat engine having a vortex combustion chamber and oval-shaped turbine and compressor chambers with cylindrical turbine and compressor rotors rotatably mounted eccentrically therein, Each rotor has at least two rectangular blades slidably mounted in slots extending through the cylindrical rotor in mutually perpendicular relation and each blade is independently movable relative to the other in a radial direction. Each blade has a guide element extending from opposed sides and through the opposed end walls of the respective rotor which are slidably received in guide grooves in the respective chamber end walls. The rotors are connected together by a shafts in concentric relation whereby rotation of the turbine rotor causes simultaneous rotation of the compressor rotor and the guide elements traveling in the guide grooves cause the blades to extend and retract radially with their outer ends following the inner periphery of the respective chamber side wall with a constant clearance. The turbine rotor is rotated by working fluid from the vortex combustion chamber which causes rotation of the compressor rotor. rotation of the compressor rotor draws air into the compressor chamber, compresses it, and discharges it. The discharged compressed air is mixed with a portion of heated working fluid discharged from the turbine chamber in a thermal exchange recuperator and the heated compressed air is conducted to the combustion chamber.
