procedure and device for utjemning of totaltryckets breakdown in kompressorinloppsplanet of inloppskanalen to luftsugande drives

摘要

In a method for obtaining a uniform total pressure distribution in the compressor inlet plane of the inlet duct (1) of air-intake engines the incoming air in the region of the boundary layer is removed from the inlet duct (1) by way of openings in the walls (9, 10) bounding the inlet duct. In order to avoid the particularly disturbing influence of the corner boundary layer (19), in the region of at least one of the intersection edges (13) of the walls (9, 10) of the inlet duct (1) the air is removed in accordance with the thickness of the boundary layer (corner boundary layer 19) to be expected there. The openings, which may be in the form of slots or holes (13), are disposed, one behind the other in the main direction of flow, in the region of the corner boundary layer. IMAGE
