Tests have been made to study the effectiveness of small pressure differences, such as exist between the inside of the airplane ducts and the external airplane surfaces suitable for duct exits, in removing the duct boundary layer through slots in the duct wall and thereby reducing separation losses. Two-dimensional diffusers of 15 and 30 degrees included angles and some 90 degree bends without a resistance at the large end. Several different types of boundary layer were set up at the diffuser inlets.
