PTVC-M for Ultra-Agile VTOL and 300+ Km·H−1 Cruising
Advances in Aerospace Science and Technology, 2016, 1, 48-57 Published Online June 2016 in SciRes. http://www.scirp.org/journal/aast http://dx.doi.org/10.4236/aast.2016.11005 PTVC-M for Ultra-Agile VTOL and −1 300+ km·h Cruising Chung-Kiak Poh*, Chung-How Poh Aero-Persistence Research, Penang, Malaysia Received 20 May 2016; accepted 28 May 2016; published 27 June 2016 Copyright © 2016 by authors and Scientific Research Publishing Inc. This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract There remains a need to develop improved VTOL techniques that are cost-effective and with mini- mum compromise on cruising flight performance for fixed-wing aircraft. This work proposes an elegant VTOL control method known as PTVC-M (pitch-axis thrust vector control with moment arms) for tailsitters. The hallmark of the approach is the complete elimination of control surfaces such as elevators and rudder. Computer simulations with a 1580 mm wing span airplane reveal that the proposed technique results in authoritative control and unique maneuverability such as inverted vertical hover and stall-spin with positive climb rate. Zero-surface requirement of the PTVC-M virtually eliminates performance tradeoffs between VTOL and high-speed flight. In this −1 proof-of-concept study, the VTOL-capable aircraft achieves a VH of 360 km·h at near sea-level. The proposed technique will benefit a broad range of applications including high-performance spinsonde that can directly measure 10-m surface wind, tropical cyclone research, and possibly serving as the cornerstone for the next-generation sport aerobatics. -
“3D Aerobatic Airplanes” As Basis for Fixed-Wing Uavs with VTOL Capability

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract There are fundamental performance compromises between rotary-wing and fixed-wing UAVs. The general solution to address this well-known problem is the design of a platform with some degree of reconfigurable airframes. For critical missions (civilian or military), it is imperative that me- chanical complexity is kept to a minimum to help achieve mission success. This work proposes that the tried-and-true radio controlled (RC) aerobatic airplanes can be implemented as basis for fixed-wing UAVs having both speed and vertical takeoff and landing (VTOL) capabilities. These powerful and highly maneuverable airplanes have non-rotatable nacelles, yet capable of deep stall maneuvers. The power requirements for VTOL and level flight of an aerobatic RC airplane are evaluated and they are compared to those of a RC helicopter of similar flying weight. This work provides quantitative validation that commercially available RC aerobatic airplanes can serve as platform to build VTOL capable fixed-wing UAVs that are agile, cost effective, reliable and easy maintenance. -

Manual Helicopter
Manual Setting Helicopter Setting up a helicopter Setting up a helicopter for its first flights can be a daunting task, even after you've done it a few times. There is more than one "right" way to do it, and a lot of room for personal preference s, so I don't claim that this page describes the "one true setup" for everyone. What it does describe is the process I use to set up my own helicopters, as well as those of beginners who ask for my assistance. I will walk though the setup, step by step, ex plaining what I do and why I do it. General principles... • 90 degree angles are your friend. With the controls centered, imagine a short line from the center of the servo horn to the ball link. This line should be perpendicular (at 90 degrees to) the link age attached to that ball. If it isn't, you'll find that you get more control throw in one direction than the other, which will leave you with a helicopter that feels different depending on which way you're turning or tumbling. Helicopters are hard enough to fly already; bad setup only makes them more difficult still. • Slop is not your friend. Grab the swashplate and wiggle it up and down... try to tilt it in every direction. Notice any slop? Find and fix the sources. Grab the blade grips and twist them. No tice any slop? Find and fix the sources of the slop. With all those linkages and pivots between the blade grip and the servo horn, there's bound to be some slop, but do everything you can to minimize it.
