FIELD: engines and pumps. ^ SUBSTANCE: aircraft engine nacelle thrust reverser comprises front frame, cowl with drives and inner structure. Front frame is arranged downstream of compressor case fitted in nacelle. Cowl is arranged to displace between closed position whereat it covers front frame, open position whereat it opens front frame, and preliminary position of maintenance whereat it is located downstream of front frame. Aforesaid internal structure is arranged to displace between working position whereat it is partially closed by front frame and, in its turn, closes section of turbojet engine to make annular cold air passage together with cowl, and preliminary position of maintenance whereat it is located downstream of front frame. Aforesaid cowl is made up of two flaps while internal structure consists two internal flaps. Note here that flaps and internal flaps may open outward when bowl and inner structure stay in preliminary position of maintenance. Another invention of proposed set relates to aircraft engine nacelle with above described thrust reverser. ^ EFFECT: simplified access to turbojet engine for servicing. ^ 14 cl, 22 dwg |
