초록

The invention concerns a control for an aircraft propeller. During operation in reverse pitch, as occurs upon thrust reversal during a landing maneuver, the speed of the propeller is controlled by adjusting pitch of the propeller, in order to prevent overspeeding. Further, during the transition period while the propeller is converting from forward pitch to reverse pitch, the propeller presents a light load to the engine. At this time, fuel flow to the engine is limited in order to restrict delivery of energy to the propeller, again, for the purpose of pr...

청구항

A system for controlling an aircraft propeller driven by an engine, comprising: a. means for detecting a reverse signal demanding a reversal in thrust and b. means for placing a limit on fuel flow to the engine in response to the reverse signal.
