Abstract
An actuator release mechanism includes an axially moveable member biased in a first axial position by a bias spring and driven to a second axial position by an actuation means such as a solenoid arranged in substantially the same axis as the axially moveable member. The axially moveable member can be a piston.
Claims10
A ram air turbine (RAT) actuator release mechanism comprising:
- a longitudinal member moveable along an axis between a lock position and a release position;
- bias means to bias the longitudinal member in one of the lock position and the release position;
- and
- actuation means arranged to cause the longitudinal member to move along the axis away from the one position and towards the other of the lock position and the release position;
- wherein the bias means is a toggle spring that, when the actuation means are not activated, is in a relaxed state that biases the longitudinal member towards a lock bolt to prevent movement of the actuation means.

A ram air turbine (RAT) actuator assembly comprising:
- a lock bolt;
- and
- an actuator release mechanism moveable relative to the lock bolt to permit or prevent axial movement of the lock bolt, the actuator release mechanism comprising:
- a longitudinal member moveable along an axis between a lock position and a release position;
- bias means to bias the longitudinal member in one of the lock position and the release position;
- and
- actuation means arranged to cause the longitudinal member to move along the axis away from the one position and towards the other of the lock position and the release position;
- wherein the bias means is a toggle spring that, when the actuation means are not activated, is in a relaxed state that biases the longitudinal member towards the lock bolt to prevent movement of the actuation means.
