Abstract:
This paper describes the aerodynamic and flight dynamic modeling of a biplane tailsitter Unmanned Aerial Vehicle (UAV) that is capable of vertical takeoff and landing (VTOL) and high efficiency cruise flight. The conventional quasi-steady aerodynamic model is enhanced incrementally while discussing the limitations of the models. The effect of model refinement on the forward transition trajectory is studied as it involves most of unsteady effects due to the aggressive nature of forward transition maneuver in which the UAV pitches by 90 degrees. An octarotor biplane tailsitter vehicle is fabricated and instrumented to collect flight test parameters for the transition flight. The states of the UAV during the transition flight are recorded onboard using the autopilot and are subsequently used to validate the simulation. The use of unsteady aerodynamic model helps improve the predicted flight trajectory.
