Rotary wing aircraft, has rotor blade whose angle is adjusted by shifting rotor to specific degrees by engine jib and by assembling engine at propeller shaft to adjust propeller traction force for providing blade resetting force

摘要

The aircraft has an engine jib that shifts a rotor to 90 degrees to adjust an angle of a rotor blade by adding a required angle dependent on the load. The engine (7) is assembled at a propeller shaft in an engine pod (6) to optimally adjust propeller traction force for providing a resultant blade resetting force to adjust the angle. Return springs pull the blade to a maximum angle during the increased propeller rotation.
