Abstract:

This report describes the development program for a high temperature hydraulic rotary actuator based on the DYNAVECTOR concept. Included are illustrated results based on replies by six airframe companies to a Bendix survey that determined the projected 1975-80 horizontal tail and rudder actuator stiffness requirements for fighterattack aircraft, as well as the critical design conditions relative to Mach number and altitude. Also reported are the results for the 800 F ambient testing of three different shaft seals designs created for the program that are presented in terms of leakage versus time, temperature and pressure. Actuator test results -- with and without the epicyclic gear transmission -- and analyses included in the report reveal that the limitation imposed by the particular transmission disengagement concept used for load decoupling actuator redundancy application prohibitively detracts from the performance of the actuator for analog control.
