FIELD: engines and pumps. ^ SUBSTANCE: aircraft nozzle comprises funnel and plug secured to funnel walls and having circular groove. Said disk-shaped plug is made from rapid-combustion material, preferably, foam plastics, is arranged inside said funnel flush with funnel edge and equidistant with funnel inner surface. Plug outer side surface has radial circular groove. Radial slot is made on plug face surface, opposite aforesaid radial circular groove. Plug is secured to funnel inner surface by organic binder applied on the part of plug outer side surface as far as to circular groove on the side of plug smaller diametre. ^ EFFECT: protection of nozzle inner space against external effects, particularly against pressure exceeding that of plug ejection pressure, without increasing plug sizes. ^ 1 dwg |
