ABSTRACT:
An operator for lowering and retracting two or more landing gear on an aircraft with a single motor. The output of the motor is modified by a reduction gear assembly, then rotates a drive shaft of each drive, there being one drive for each landing gear assembly. Output of each drive shaft turns a universal joint, then a screw shaft fixed to the universal joint. The screw shaft is arranged to turn in a threaded collar fixed to a tubular stabilizing strut connected to the main strut of the landing gear such that rotation telescopically extends and contracts the paired strut and screw shaft when the latter rotates. Two opposing landing gear are driven by mirror image drives of the operator. Optionally, a third drive shaft and screw shaft lower and retract the nose wheel or tail wheel of the aircraft.
