Validation of Quad Tail-sitter VTOL UAV Model in Fixed Wing Mode

Vertical take-off and landing (VTOL) is a type of unmanned aerial vehicle (UAV) that growing rapidly because its ability to take off land anywhere in tight spaces. One VTOL UAV, the tail-sitter, has best efficiency. However, besides efficiency offered, some challenges must still be overcome, including complexity combining hover like helicopter fly horizontally fixed-wing aircraft. This research two contributions: form how analytical model generated tools used (specifically for small quad tail-sitter UAV) utilize off-the-shelf components UAV empirical modeling. focuses on increasing speed accuracy control design mode. The first step carry out analysis simulation. analytically obtained using OpenVSP longitudinal lateral modes. next realize this both aircraft controls. third measure flight characteristics Based data recorded during flights, an made system identification technique. final vali-date with model. results show mode fulfill specified requirements are close Thus, it can concluded implemented directly, consequently, development process been shortened.
