Abstract

A split flap 1 is partially balanced by the pressure within a bellows connecting the flap to the under surface of the wing 3, of air from the external stream admitted through one or more openings 8 in the flap. As shown the bellows is formed of fabric 7 connected to the under surface of the wing at C and to the upper surface of the flap at D, and is divided into three compartments by perforated diaphragms 6. To prevent any tendency to self‐opening when the flap is closed or only slightly lowered a deflector 9 is placed in front of each opening 8 to cause a reduction of the internal pressure in the bellows under such conditions, the deflector having little or no effect at large flap angles.
