Изобретение относится к авиационной технике. Цель изобретения - улучшение эффекта шумоглушения. Это достигается тем, что средняя обшивка по отношению к внешним установлена под углом.The invention relates to aircraft. The purpose of the invention is to improve the effect of sound attenuation. This is achieved by the fact that the average casing with respect to the external is set at an angle.
