The invention relates to aeronautical engineering, and specifically to the construction of aviation engines and aeroplane braking devices, and can be used in a cascade-type thrust reverser rotating cascade made of polymer composite materials. A thrust reverser rotating cascade of an outer body of an engine includes monolithic sections. Each section is made of a polymer composite material and includes longitudinal ribs and transverse rotating vanes. The sections are attached using a front flange to a front bulkhead of a load-bearing frame of the thrust reverser by means of a detachable connection, and using a rear flange to a rear bulkhead of the load-bearing frame of the thrust reverser by means of a detachable connection. The longitudinal ribs and transverse rotating vanes in each section are 1.5-10 mm thick. The longitudinal ribs are capable of directing the outflow of the reversing jets at an angle β = 0° - 40° to the radial direction. The transverse rotating vanes are disposed at an angle γ = 40° - 80° to the longitudinal axis of the engine. The technical result of the claimed invention is to create a high-tech design for a thrust reverser rotating cascade, to improve the operational reliability of the thrust reverser and to simplify assembly/disassembly of the thrust reverser rotating cascade. 5 figs.
