© 2016, (publisher Name). All Rights Reserved. The Applied Vehicle Technology Panel Task Group AVT-202 “Extension of Fundamental Flow Physics to Practical MAV Aerodynamics” has introduced four canonical cases. Rectilinear pitch is probably the most studied one, especially considering its parametric variations. The canonical case of rectilinear pitch considers a rectangular flat plate wing of aspect ratio 4, with a thickness of less than 5% and round edges, undergoing a pitch up motion in a freestream. In the beginning, the wing is at condition CL = 0 and then pitches up to 45° of effective incidence either in 1 or 6 chord lengths of travel relative to fluid (known as fast and slow cases), pivoting around its leading edge. This paper focuses on parametric variations of the aforementioned canonical case, namely variations in aspect ratio, leading edge and planform shapes.
