Flight Envelop of a Tail-Sitter Unmanned Aerial Vehicle
A prototype of a tail-sitter mini unmanned aircraft (UAV) was developed and subjected to wind-tunnel tests and automatic flight tests. A tail-sitter is an aircraft that takes off and lands on its tail section, with the fuselage pointing upwards. One of the key features of the prototype is that its wing is equipped with leading-edge slats. In previous studies, we conducted wind-tunnel tests and confirmed that the slats increase the stall AoA of the main wing. However, the pitching-trim control force was found to have a poor margin. Automatic flight tests on high-AoA flights with a pitch angle of 60° were not successful because of fluctuations in the pitch attitude caused by the poor effectiveness of the elevators. As a result, the effect of the leading-edge slats was not explicitly confirmed in the flight tests.
