Hybrid Propulsion System Design of a VTOL Tailsitter UAV
Tailsitter UAVs with their combined vertical take off and landing (VTOL) and fixed-wing aircraft with full flightspeed regime capability provides a distinct alternative to rotary-wing and ducted fan UAVs (OAVs). ITU-BYU Tailsitter concept aims to obtain the energy efficient regimes across the VTOL and the cruising flight regimes. This paper describes the hybrid propulsion system design approach...
متن کاملControl of a VTOL UAV via Online Parameter Estimation
Due to their ability to hover and to fly “low and slow” VTOL UAVs are of extreme strategic importance. The task of control of VTOL UAVs is however complicated as they exhibit highly coupled nonlinear dynamics and inherent instability. These intricacies limit the performance of linear control techniques since a single linearized state space model represents only a limited part of the flight enve...
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 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 کاملQuad 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...
