Deployment mechanism for a ram air turbine has conventionally consisted of a strut pivotally mounted within a storage bay of an aircraft and which pivots to a downwardly-extending position to bring the ram air turbine into deployed position. Such a structure has required a storage bay in the aircraft having a large stowing volume because of the primarily rotational movement of the ram air turbine and has not maximized the speed of deployment of the ram air turbine. The improved deployment mechanism for the ram air turbine has front and rear linkages pivotally connected at one of their ends within the storage bay of the aircraft and their other ends pivotally connected to the ram air turbine and includes a spring-loaded deployment actuator operable to move the ram air turbine from stowed position. The front and rear linkages are constructed and mounted at pivot joints to provide primarily a linear motion of the ram air turbine in moving between stowed and deployed positions to provide for fast deployment and also minimize the volume of the storage bay and the area of the access doors thereto.

CM,1. A deployment mechanism for a ram air turbine movable between stowed and deployed positions and having a mounting base mountable on an aircraft frame component comprising, a front link having a rear pivot joint connection to said mounting base and a front pivot joint connection to the ram air turbine and changing from a generally horizontal to a generally vertical disposition as the ram air turbine moves from stowed to deployed position, a rear link having a rear pivot joint connection to said mounting base beneath said rear pivot joint connection of the front link and a pivot joint connection to the ram air turbine rearwardly of the front link pivot joint connection, said rear link extending generally horizontal in side-by-side parallel relation with and beneath the front link when the ram air turbine is in stowed position and moving to a generally vertical position and in parallel side-by-side relation with the front link when the ram air turbine is deployed.
