发明名称 Ram air turbines
摘要 A ram air turbine has blades 1 mounted on a hub 5. Inside the hub each blade 1 support a counterweight 60 arranged to alter the pitch of the blades as speed varies. Each counterweight 60 is coupled with an actuator 91 by which the angle of the blades can be altered remotely. The turbine is stopped rotating by altering the angles of the blades 1 such that the hub 5 rotates slightly in the reverse direction, which causes a sprag clutch 52 to lock the turbine 5. The actuator 91 is also coupled with an additional brake 100, which is applied after the clutch 52 locks.
