POWERED MODEL INVESTIGATION OF THE EFFECTS OF GATED SPOILERS ON THE AERODYNAMIC CHARACTERISTICS OF WINGS AT ANGLES OF ATTACK FROM 0 TO 90 DEGREES,

Abstract

An investigation was conducted to evaluate the effects of a gated spoiler near the upper surface leading edge of a propeller powered wing model. The device was considered appropriate for solution of a particular handling qualities problem in tilt-wing V/STOL aircraft that is related to wing stall phenomena. The data gathered indicate that a descending-decelerating approach of perhaps 20 degrees may be possible with the spoiler system. The most significant aspect of the benefits of the subject spoiler lies in the probable high insensitivity to wing planform (aspect ratio) which will allow freedom in the optimization of wing design.
