High Angle of Attack Flight of a Tail-Sitter UAV

摘要：

We conducted high angle of attack (AoA) flight tests on the prototype of a tail-sitter mini unmanned aerial vehicle (UAV). A tail-sitter is an aircraft that takes off and lands on its tail section with the fuselage pointing upwards. A key feature of the prototype is the leading edge slats, which are incorporated in its design to avoid stall during high angles of attack (AoA) flight In a previous research, through wind tunnel tests-aerodynamic force measurements and airflow visualization via the tuft method-it was confirmed that the slats increase the stall AoA not only in the non-powered (without propeller) condition but also in the powered (wing in propeller slipstream) condition. In order to demonstrate the effect of the slats, the automatic high AoA flight tests, up to pitch angle θ≈50° was successfully conducted. Although the vehicles high AoA flight characteristics were verified, several useful insights were obtained that require further investigation.
