Takeoff configuration:
Rotor blades in blue with collective pitch, thrusters in black oriented for takeoff,control surfaces in red oriented in thrusters' airflow.
Takeoff configuration:
Top view.
Takeoff configuration:
Front view.
Forward flight configuration:
Thrusters rotated to provide propulsive thrust, rotor blades pitched to comprise a disk-like wing.
Notes on operation in takeoff and landing:
*Control surfaces direct thruster airflow up or down independently to control pitch and roll.
*Thruster throttle controls yaw.
*Main rotor pitch controls vertical movement and plays a role in pitch.
Notes on operation in transition to forward flight:
*Thrusters rotate incrementally to provide a transition from yaw/pitch/roll control in vertical flight, to yaw/pitch/roll control in forward flight.
*Main rotor-blade lift comes from rotation initially, and from forward movement as a disk-shaped wing ultimately in foward flight.
Notes on operation in forward flight:
*Control surfaces act as elevons, providing pitch and roll control. Yaw control is obtained from incremental thruster rotation.
*Pitch stability is afforded partially from control surfaces and from wing section in green.
*Yaw stability is afforded from thruster ducts or from fins (fins not shown)
