Abstract:
The process of increasing the efficiency and output of a gas-turbine having blades in a combustion chamber (7) which includes cooling the gas-turbine blades (10) with a liquid-fuel and mixing the fuel used for cooling with air in the combustion chamber (7) and burning the mixture and driving the turbine (15) by the exhaust from the combustion chamber (7). This allows the fuel and air to be in stoichiometric mixture. Preferably the fuel is a liquid-gas such as hydrogen. The turbine (15) may be cooled by injecting liquid-fuel onto its disk (11) to provide a film coating which is centrifuged around the blades whereby the liquid will cool both the interior and exterior of the blades and the absorbed heat is introduced into the combustion chamber (7). The combustion chamber (7) includes a plurality of air inlets (8). The turbine (15) drives a compressor, and the compressor and the air inlet may be cooled with the liquid-fuel, which may be cryogenically cooled. An improved jet engine which is convertible from a turbo to a ram-jet is provided.

Abstract:
An internal combustion engine which is combined with a thermal cycle of the Rankine type in which water is heated to steam and injected into the engine along with the fuel for increasing the engine output. Increased power can be provided with a turbine compressor (16) receiving the exhaust from the engine and compressing the air intake to the engine. An additional fuel burner (22) may be provided to drive the turbine to provide still further increased and immediate power. The engine may be run either as a two stroke or four stroke engine. A single valve (7) may be used to communicate the engine cylinder with the air intake and exhaust when used in conjunction with a rotating valve (8) which selectively communicates the single valve with the air inlet or outlet. A two cycle engine having a precombustion chamber (35) has an opening which receives a piston profile (38) for providing increased performance.
