METHOD OF REDUCTION OF DRAG OF MOVING BODIES AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2008 - IPC B64C23/00 B63B1/38 

FIELD: transport facilities; reduction of drag of moving bodies.

SUBSTANCE: jets of working medium changing running of external medium from incoming to pre-midsection radial drift from body are discharged over normal relative to nose elongated section of nose part of its body which is provided with supply passages for bypass of reverse flow of working medium or at least one of its components to nose part at adjustable flow rate from cruising engine-propulsor and correction of heading and/or pitch-trim by reverse bypass flow and radial flow of working medium. Device proposed for realization of this method has elongated nose section made from concentric tubular members of different length which form central axial and circular working passages; at least one of them is provided with profiled nozzle; the remaining peripheral circular sections are longitudinally and radially divided into sections; walls of peripheral passages which are boundary relative to external medium have shaped openings with sharp edges and guide blades and bent profiled nozzles. They are intended for positive direction of escaping flow at normals relative to incoming external medium. Adjustable delivery of working medium from cruising engine-propulsor to elongated section of nose part for its minimum one profiled passage with nozzle and separately for its peripheral guides is carried out via separate bypass passages of body. Nose part of body is provided with device for adjustable selective shutting-off of reverse flow of working medium: outlets of half of bypass passages to manifold and/or inlet of at least one of sections into guide working passages.

EFFECT: enhanced efficiency of reduction of transport facility drag.
