Ram air turbine with a speed engaged clutch

摘要

A ram air turbine with a turbine assembly and a power train, the turbine assembly only coupling to the entire power train upon reaching a desired rotational speed of the turbine assembly, the ram air turbine having a clutch mechanism, the engagement of which couples the turbine assembly to at least a portion of the power train, and a speed control mechanism that engages the clutch mechanism only when the turbine assembly attains at least the desired rotational speed.

1. A ram air turbine with a turbine assembly and a power train, the turbine assembly only coupling to the entire power train upon reaching a desired rotational speed of the turbine assembly, comprising:
a clutch mechanism comprising a clutch disc that has a rotational freedom of movement about an axis of the clutch mechanism and is axially movable relative to the axis of the clutch mechanism and a clutch disc that is axially fixed relative to the axis of the clutch mechanism, with the axially movable clutch disc and the axially fixed clutch disc each having clutch facings that face each other; and a speed control mechanism comprising at least one spring with an axis of the spring in coincidence with the axis of the clutch mechanism that engages the clutch mechanism only when the turbine assembly attains at least the desired rotational speed.
