1. An engine heater system for supplying compressed air to an air brake of a vehicle, the engine heater system comprising:
a gas turbine having an intake side opposite an exhaust side;
a combustor disposed proximate to the intake side of the gas turbine, the combustor being configured to provide heated air to the gas turbine;
a compressor having an inlet side opposite an outlet side, the outlet side being disposed proximate to the combustor and fluidly coupled to an air reservoir of the vehicle, the air reservoir being fluidly coupled to the air brake of the vehicle; and
a shaft operably coupled between the gas turbine and the compressor,
wherein during rotation of the shaft via the gas turbine, the shaft rotates the compressor, thereby increasing pressure at the outlet side of the compressor and supplying compressed air to the air reservoir of the vehicle for operating the air brake of the vehicle.
