Abstract
Abstract A GAS TURBINE ENGINE WHICH CAN UTILIZE HIGH VELOCITY GAS JETS TO ATTAIN HIGH EFFCIENCY AND POWER OUTPUT COMPRISING A ROTATABLE COMBUSTOR WHEEL ON WHICH THE COMBUSTION CHAMBER AND NOZZLE ARE MOUNTED. THE NOZZLE FORMS A GAS JET WHICH FALLS DIRECTLY ON A TURBINE BLADE WHEEL TO DRIVE IT, AND TO ROTATE THE COMBUSTOR WHEEL IN THE OPPOSITE DIRECTION BY JET REACTION. AIR IS FED TO THE COMBUSTION CHAMBER THROUGH A SCOOP MOUNTED ON THE COMBUSTOR WHEEL NEAR ITS CIRCUMFERENCE, TO EFFICIENTLY BOOST AIR PRESSURE AND ACHIEVE THE REQUIRED HIGH AIR FLOW.
