A turbine for producing power for any of a variety of uses, such turbine having as a principal distinguishing characteristic, the use of a turbine wheel having an active surface of undulating, washboard configuration, against which hot gases are directed in an angular relationship. This undulating portion of the turbine wheel comprises alternating peaks and valleys disposed around the periphery of the wheel on a regular recurring basis. Closely adjacent the undulating portion of the wheel are a series of stationary, exhaust-collecting members that are spaced apart to permit the directing of hot gases at the active sides of the undulations, such that rotation of the turbine wheel in the desired direction is brought about. Within the spirit of this invention are numerous cool-gas-carrying passages in the turbine wheel, finding their exit on the active surface of the turbine wheel, but in each instance on the side of the undulations essentially parallel to the flow of hot gases. Quite significantly, these passages bring about the creation of a layer of cool air which flows along the undulations, shielding them from the deleterious effect of the hot gases, and thereby forming a hot-cold boundary that is adjacent to but spaced from the turbine wheel. This hot-cold boundary acts as a variable “air-blade”which adopts efficient shapes over a broad range of engine speed and load conditions.

A turbine engine including a turbine wheel with connected compressor, at least one combustion chamber wherein fuel can be burned in order to generate hot gases, said turbine wheel and compressor being surrounded by suitable housing means and being mounted for rotation, with the rotation thereof causing said compressor to supply compressed air both for the cooling of the engine as well as for utilization in said combustion chamber, said turbine wheel having means thereon including a plurality of surfaces that are essentially circularly disposed, the hot gases emanating from said combustion chamber being directly at an angle to the axis of the turbine and toward said surfaces on said turbine wheel, such surfaces being oriented at an angle essentially perpendicular to the direction of flow off the hot gases from said combustion chamber, the reaction of such hot gases upon said surfaces causing said turbine wheel to rotate and thus drive said compressor in rotation, means defining a plurality of cooling air openings in said turbine wheel, means for directing cooling air from said compressor to and through such openings in said turbine wheel such that cooling air is interposed between said surfaces and the hot gases, thus to extend the useful life of said turbine wheel, and common exhaust means for said hot gases and cooling air.
