Tiltrotor aircraft having tiltable forward and aft rotors

This invention describes an aircraft that combines vertical takeoff and landing with forward flight. It uses two wings, each with a rotor at its front and back. For vertical lift, the front rotors tilt upwards and the rear rotors tilt downwards; for forward flight, the front rotors point forward and the rear rotors point backward. A computer system independently controls each rotor's speed and tilt, allowing for smooth transitions between flight modes, either through remote operation or autonomous control.
