LOCKING MECHANISMS FOR RAM AIR TURBINES

摘要

A locking mechanism for a ram air turbine (RAT) includes a base clevis configured to mount to a housing and to have a base link clevis connector portion defining a plurality of base link clevis connector arms and a base link clevis having a base connector portion defining base connector arms that are configure to movably connect to the base link clevis connector arm. The locking mechanism also includes a pin operatively connecting the base connector portion to the base link clevis connector portion in a rotatable relationship and a spring positioned around the pin, wherein a first spring end abuts the base clevis and a second spring end abuts the base link clevis to bias the base link clevis to an unlocked position. A sleeve is positioned between the spring and the pin to maintain a wind diameter of the spring.

1. A locking mechanism for a ram air turbine (RAT), comprising:
a base clevis configured to mount to a housing and to have a base link clevis connector portion defining a plurality of base link clevis connector arms; a base link clevis having a base connector portion defining a plurality of base connector arms that are configure to movably connect to the base link clevis connector arms; a pin operatively connecting the base connector portion to the base link clevis connector portion in a rotatable relationship; a spring positioned around the pin, wherein a first spring end abuts the base clevis and a second spring end abuts the base link clevis to bias the base link clevis to an unlocked position; and a sleeve positioned between the spring and the pin to maintain a wind diameter of the spring wherein the sleeve is configured to improve the stability of the locking mechanism and enhance the force translation from the spring to the locking piston.
