Abstract

Способ глушения шума струи реактивного двигателя путем воздействия на струю высокочастотными колебаниями, отличающийся тем, что, с целью повышения эффективности шумоглушения, высокочастотные колебания создают лазерными лучами, направляемыми поперек струи и равномерно по ее сечению с частотой, превышающей частоту шума струи не менее, чем в 2 раза, причем на площадь, не превышающую 15% от площади струи, направляют по меньшей мере один луч.The method of jamming jet jet noise by exposing the jet to high-frequency oscillations, characterized in that, in order to increase the sound attenuation efficiency, high-frequency oscillations are created by laser beams directed across the jet and evenly over its cross section with a frequency exceeding the frequency of the jet noise 2 times, at least one beam is directed to an area not exceeding 15% of the jet area.
