Gas turbine engine operating process

Abstract

The process of increasing the efficiency and output of a gas-turbine having blades in a combustion chamber which includes cooling the gas-turbine blades with a liquid-fuel and mixing the fuel used for cooling with air in the combustion chamber and burning the mixture and driving the turbine by the exhaust from the combustion chamber. Preferably the fuel is a liquid-gas such as hydrogen. The turbine may be cooled by injecting liquid-fuel onto its disk 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. The combustion chamber includes a plurality of air inlets. The turbine 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 ramjet is provided.
