ABSTRACT:
An air turbine flow restrictor comprises a sensor for determining the rotational velocity of the turbine wheel. In response to a detected speed above a predetermined threshold, particles are injected into the inlet airstream. In one embodiment of the invention, the particles are metal disks. The disks, carried by the airstream become lodged in the nozzles of the air turbine, thereby restricting the flow of air to the turbine wheel.
