Abstract: FIELD: rocket engineering. 
     SUBSTANCE: invention relates to rocket engineering, namely to a design of a rocket engine nozzle. The flexible nozzle attachment is comprised of a flexible shell with a pile layer, a flexible sublimating material is located on the inner side of the shell, wherein the threads of the pile of a heat erosion-resistant material pass through said material, wherein the ends of the threads of said pile are directed along the wall of the attachment towards the outlet section of the attachment, the height of protrusion of the threads relative to the inner surface of the stationary part of the nozzle does not exceed the thickness of the turbulent boundary layer in the section of adjoining of the flexible attachment with the stationary part of the nozzle. The flexible nozzle attachment provides a reduction in the longitudinal dimensions of the nozzle in the initial folded transport position and a nozzle thrust with a large expansion in the unfolded operating position. The pile layer is used to protect the flexible shell from the thermal and erosion impact of the fuel combustion products. The limited protrusion of the threads of the pile relative to the inner surface of the stationary part of the nozzle allows reducing the impact of the flow of combustion products with a lower velocity in the boundary layer on the pile layer. The sublimating material prevents thermal destruction of the sealed shell, preventing the temperature of the inner surface of the shell from rising above the sublimation temperature.  
     EFFECT: invention increases the protection of the flexible nozzle attachment from the impact of the flow of high-temperature fuel combustion products during the entire operating time of the rocket engine.
