Abstract:

A propeller protector for a countermeasure vehicle having a propeller shaft, a propeller fixed to the shaft, radial fins fixed on the vehicle and extending outwardly from the shaft, and a shield fixed to the fins and surrounding the propeller. The propeller protector includes a sleeve having an end wall at a first end thereof, and an open second end engaged with the vehicle, the first end and side walls of the sleeve having perforations therein. The sleeve first end is provided with a central opening. A nut is fixed to the sleeve end wall, threadedly mounted on the shaft, and disposed around the central opening. Stop structure on the sleeve and the vehicle prevents rotation of the sleeve relative to the vehicle. Rotation of the propeller shaft unscrews the shaft from the nut, permitting the nut and the sleeve to move axially to disengage from the vehicle.
