FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering, particularly, to aircraft engine attachment assembly bottom rear streamlined cowling. Cowling 30 comprises two lateral panels 44 jointed by transverse inner ribs 46 spaced apart in cowling lengthwise direction X. Cowling 30 comprises also heat-protection cover 32 blown by engine first stage flow 36. In compliance with this invention, cowling 30 comprises additionally two lengthwise connection walls 58 separating said heat-protection cover 32 from inner transverse ribs 46. Note here that first lateral end 62 or every said connection walls 58 is secured at appropriate lateral end of heat-protection cover 32 while second lateral ends 64 are secured to transverse inner ribs 46.
EFFECT: better aerodynamics.
