There remains a need to develop improved VTOL techniques that are cost-effective and with minimumcompromise on cruising flight performance for fixed-wing aircraft. This work proposes anelegant VTOL control method known as PTVC-M pitch-axis thrust vector control with momentarms for tailsitters. The hallmark of the approach is the complete elimination of control surfacessuch as elevators and rudder. Computer simulations with a 1580 mm wing span airplane revealthat the proposed technique results in authoritative control and unique maneuverability such asinverted vertical hover and stall-spin with positive climb rate. Zero-surface requirement of thePTVC-M virtually eliminates performance tradeoffs between VTOL and high-speed flight. In thisproof-of-concept study, the VTOL-capable aircraft achieves a VH of 360 km·h-1 at near sea-level.The proposed technique will benefit a broad range of applications including high-performancespinsonde that can directly measure 10-m surface wind, tropical cyclone research, and possiblyserving as the cornerstone for the next-generation sport aerobatics.
