FIELD: transport.SUBSTANCE: invention relates to aircraft engineering, particularly, to overpressure release hatch 21 mounted at turbojet nacelle wall 23. Said hatch 21 has support secured to wall 23 and release element 25 sliding relative to said support 22. Hatch 21 has part 27 of lower mechanical strength as compared with other hatch parts to allow withdrawal of air at overpressure inside nacelle 1 in case internal pressure at said hatch increases, in fact, to threshold magnitude smaller than maximum pressure withstood by nacelle structure.EFFECT: higher efficiency of overpressure release, decreased weight.16 cl, 21 dwg |
