ABSTRACT:
A helicopter that adopts a two-stroke internal combustion engine equipped with a centrifugal force-resistant propeller fan or fan turbine, or that can rotate clockwise (CW) and counterclockwise (CCW) during driving to directly propel the rotors and realize flight using a rotor wing that reconfigures into a hovering state. The helicopter reduces emissions via improved ventilation and a scavenging air system, reduces aerodynamic loss, reduces the access fee, and possesses the functions of a rotor wing that reconfigures into a hovering state.
