Abstract
Report presenting a wind-tunnel investigation to determine the low-speed aerodynamic characteristics of an airplane arrangement with an unswept horizontal tail and a triangular wing with an aspect ratio of 3 equipped with partial-span single-slotted flaps and plain ailerons. The effects of flap deflection on the longitudinal characteristics were investigated at several tail positions. Results indicated taht satisfactory longitudinal stability up to a lift coefficient of 1.35 was attained only when the tail was below the wing-chord plane.
