Abstract
A rotorcraft aircraft design incorporates double swept forward and aft rotor blades configured to provide efficient hover and efficient cruise at Mach number of 0.65-0.7 without varying a diameter of the rotor. The aircraft design combines the benefits of helicopters and fixed-wing aircraft, enabling vertical takeoff and landing (VTOL) capabilities while also achieving improved forward flight speed and reduced noise emissions.
