Title:
FAULT-TOLERANT ROTARY ACTUATOR
Document Type and Number:
WIPO Patent Application WO2004027266
Kind Code:
A3
Abstract:
A fault-tolerant actuator module, in a single containment shell, containing two actuator subsystems that are either asymmetrically or symmetrically laid out is provided. For actuator (100), duality is achieved by summing the equal prime mover forces against output plate (106) through a pair of geared transmissions. Prime mover (110) drives gear train (104) to create a torque on the output attachment plate through clutch (114). Similarly, prime mover (102) drives gear train (112) to create a torque on the output attachment plate (106) through clutch (108). Should the subsystem incorporating prime mover (102) and gear train (112) fail, clutch (108) would be energized to take that subsystem out of service. In certain embodiments, prime movers (102) and (110) exhibit substantially identical performance characteristics (e.g., generate substantially identical torque output and operate across a similar range of speeds).
