An open cycle gas turbine system includes a storage tank, a closed helical supplier, a combustor, a gas turbine, a compressor, a propeller and a generator. After the combustion gas in the combustor enters the gas turbine, the combustion gas is expanded to apply a work and to produce a power to the gas turbine so as to operate the gas turbine so that the compressor is operated to compress the air, the generator is operated to generate an electric power, and the propeller is operated to propel vehicles. The closed helical supplier has a closely sealing effect so that the high pressure combustion gas in the combustor will not leak from the closed helical supplier and will not touch the solid fuel powder in the storage tank.
