ROTOR BLADE SUBASSEMBLY

摘要

PROBLEM TO BE SOLVED: To provide a rotor type UAV used for a reconnaissance flight and a communication mission over a wide area, especially for a strategic reconnaissance flight. SOLUTION: A unmanned aerial vehicle(UAV) 10 has a complex circular body structure 20 surrounding a rotor assembly 100 including a pair of coaxial multi-blade counter-rotating rotors. The circular body structure 20 includes a circular C-shape structure. The circular C-shape structure defines a detachable panel structure mounted with a combination of a cavity and the circular C-shape structure. The UAV has a drive train assembly having a sprag clutch, an engine coupled subassembly, transmission coupled subassembly, and a drive shaft.
