Abstract
1. Способ ослабления волнового отрыва при взаимодействии скачка уплотнения с пограничным слоем на обтекаемой поверхности, включающий отсос части потока через перфорацию в поверхности в полость под ней на участке обтекаемой поверхности за скачком уплотнения, отличающийся тем, что у обтекаемой поверхности перед скачком уплотнения создают продольные вихревые жгуты путем выдува ряда поперечных струй из протоков в поверхности, соединяемых каналом с полостью под перфорированным участком поверхности.2. Способ по п.1, отличающийся тем, что выдув поперечных струй перед скачком уплотнения выполняют с наклоном под углом 30-60° к обтекаемой поверхности поперек направлению потока.1. A method of attenuating wave separation during the interaction of a shock wave with a boundary layer on a streamlined surface, including the suction of a part of the stream through perforation in the surface into a cavity below it on a section of the streamlined surface behind the shock wave, characterized in that longitudinal swirls are created at the streamlined surface before the shock wave harnesses by blowing a number of transverse jets from the ducts in the surface, connected by a channel to the cavity under the perforated surface. 2. The method according to claim 1, characterized in that the blowing of the transverse jets before the shock wave is performed with an inclination at an angle of 30-60 ° to the streamlined surface transverse to the direction of flow.
