ROTARY ACTUATOR FOR FLIGHT CONTROL SURFACE
This abstract first appeared for US patent application 18595790 titled 'ROTARY ACTUATOR FOR FLIGHT CONTROL SURFACE
Original Abstract Submitted
A rotary actuator for a flight control surface includes a first electric motor connected to a first geartrain having planetary gearsets in series and a first drive gear driven by the first electric motor via the first geartrain. The first geartrain and the first drive gear define a first powertrain. The rotary actuator also includes a second electric motor connected to a second geartrain having planetary gearsets in series. The second geartrain is separate from the first geartrain. The rotary actuator further includes a second drive gear driven by the second electric motor via the second geartrain. The second geartrain and the second drive gear define a second powertrain that is coaxial with the first powertrain. Additionally, the rotary actuator includes an output shaft parallel to the first and second powertrains. The output shaft is driven simultaneously via the first and second drive gears.
