Abstract
A compressed air turbine driven fan having an axial blade fan impeller driven by a partial admission radial inflow air turbine, with both the fan blades and the turbine blades mounted on the hub rim of a single fan-turbine wheel. The turbine exhaust is discharged into a cavity surrounding the shaft of the fan-turbine wheel. In a preferred embodiment, a sound surpressing muffler made of plates having air passage offset from each other is provided with the cavity. Turbine exhaust air exists through the passages to mix with the fan flow.
