Quad Tilt Wing VTOL UAV: Aerodynamic Characteristics and Prototype Flight
A QTW VTOL UAV, featured tandem tilt wings and propellers mounted at the mid-span of each wing, is one of the most promising UAV configurations having both a VTOL capability and high cruise performance. A small prototype QTW UAV has been constructed to prove the concept and full transition between vertical and horizontal flight has been successfully demonstrated under remote manual control. The...
متن کاملTransition Flight of Quad Tilt Wing Vtol Uav
The QTW VTOL UAV, which features tandem tilt wings with propellers mounted at the mid-span of each wing, is one of the most promising UAV configurations, having both VTOL capability and high cruise performance. A six-degree-of-freedom dynamic simulation model covering the full range of the QTW flight envelope was developed and a flight control system including a transition schedule and a stabil...
متن کاملVTOL UAV Altitude Flight Control Using Fractional Order Controllers ⋆
In this paper, a fractional order flight controller design scheme for the altitude control of vertical take-off and landing (VTOL) UAV is presented. The altitude control system can be decoupled and identified as a simple first order plus time delay model under some constraints. Based on this identified model, the traditional modified Ziegler-Nichols PI controller can be designed. Meanwhile, the...
متن کاملThe Flight Control System of the Hovereye® VTOL UAV
This overview paper covers the flight control system of Bertin Technologies’ Hovereye ® mini vertical takeoff and landing (VTOL) UAV, including development, verification in simulation and flight test results. Hovereye ® is a demonstrator of a short range reconnaissance platform in support of army units engaged in urban combat, such as in peace-keeping missions, with an electro-optic day or nigh...
متن کاملThe Interactive Physics Flight Simulator
This paper describes a modelling approach to the dynamics of the airplane flight aimed at designing and realizing a simple but realistic ‘‘flight simulator,’’ able to mimic the longitudinal behaviour of a real airplane. The model is implemented by using the Interactive Physics simulation environment. The simulator is used to reproduce all the phases of a complete flight of a light commercial ai...
