An overspeed protection system is provided for a turboprop engine. The engine includes a governor pump and a constant speed governor both of which are driven by the turbine through a gear reduction assembly. The constant speed governor is in communication with the pitch adjustment means of the propeller and is operative to effect adjustments in the propeller pitch. The system further includes a pressure sensitive switch that is operative to sense a decrease in pressure of the fluid flow produced by the governor pump and thereby sensing a system failure. ...
An overspeed protection system for a turboprop engine comprising a turbine, an array of propeller blades rotatably driven by gear reduction drive means operatively engaged with said turbine, a fluid actuated pitch adjustment means mounted to said array for adjusting the pitch of the propeller blades, and a source of fluid in communication with said pitch adjustment means, said overspeed protection system comprising: a governor pump in communication with the source of fluid for producing a constant pressure flow of the fluid from said source; a constant s...
