可変ノズルを用いた推進型VTOL

抄録

We present a pusher configuration VTOL aircraft which combines the advantages of Rotating-wing aircraft and Fixed-wing aircraft. In previous researches, we developed DFO3 that has Gimbal mechanism for thrust vectoring, and controlled it 3-axes attitude by PI-D control. PID gain has calculated by pole placement method and its simulation. We succeeded VTOL and hovering maneuver. However, DFO3 has some problems. Therefore we developed DFO4 that has vectored nozzle mechanism instead of Gimbal mechanism, and proposed PID gain setting method that apply real time flight data to transfer function with selected poles. DFO4's experiment show that vectored nozzle is effective to control attitude and VTOL maneuver. Finally, we developed DFO5 based on R/C Fixed-wing aircraft aimed to the horizontal flight.
