Strapdown, multifunction actuator apparatus comprising one or two integral units adapted for installation in an aircraft, particularly a helicopter, and coupled between the pilot\s control stick linkage and the aircraft control surface (or surface servo boost) linkage to perform the functions of series actuation, trim actuation, artificial feel, control position sensing, and control authority limits. The apparatus includes a series actuator installed in the vehicle and connected to the vehicle control linkages in the conventional parallel actuator manner; that is, it is secured directly or strapped down to the airframe and therefore greatly simplifies control system installation and reduces problems such as those associated with control rod vibration resonances normally encountered with conventional integral-with-linkage series actuator installations.

A multifunction actuator apparatus for aircraft including a series actuator, the combination comprising: housing means adapted to be mounted directly on the aircraft structure adajcent to the primary pilot controller-to-control surface actuation members and including first and second drive shafts journalled in said housing means, first linkage means drivably supported on said first drive shaft and coupled with said pilot controller member, second linkage means including a drive link drivably supported on said second drive shaft and further including a differential link coupled between said control surface member, and drive link and said first linkage means, series servomotor means including means drivably connecting said servomotor to said second drive shaft for positioning said drive link, and first and second authority limit means secured to said housing means adjacent said differential link and drive link and cooperable therewith, said first limiting means limiting the position of said pilot controller member between first predetermined maximum limits and said second limiting means limiting said drive link between second predetermined maximum limits.
