“…Many short-coupled ducted fan designs such as the one described above have been studied with special attention paid to pitchback instability because it is the primary "show-stopper" for this class of aircraft [9]. Other works examine static aerodynamics of short-coupled coleopter designs independent of fully free-body aeromechanical modes [10,11]. This is understandable as the demonstrated dangers of conversion testing (described above) often lead to complete hull loss given the problems with pitchback instabilities.…”

“…Tilt-body UAVs can change incidence angle by rotating about the spanwise shaft. A ducted fan is a type of UAV where the thrusters are enclosed within a duct [55]. Finally, a tail-sitter is a UAV that takes off and lands vertically on its tail.…”

“…Hence, this design benefits from the vertical lift off from rotary-wing designs and also gains the added aerodynamic efficiencies and long flight time of the fixed-wing design. Other designs include tilt-wing [Cetinsoy et al, 2012], tilt-rotor [Chen and Jia, 2020], tilt-body [Ro et al, 2007], and ducted fan [Deng et al, 2020].…”
