FLIGHT MEASUREMENTS OF AUTOMATIC TRAILING EDGE SUCTION ON A SAILPLANE

Abstract

An investigation was conducted to determine the flight characteristics of a sailplane equipped with a trailing edge suction slot and special wing tips. An experimental, iterative method was used to locate and shape the upper-surface openings on the tips for high suction-pressure production. A drag polar determination showed no improvement in performance with the automatic trailing-edge suction; the maximum lift coefficient was no higher than that for a plain wing. Trailing-edge suction applied assymmetrically in still air resulted in a rolling behavior which was insufficient for effective lateral control.
