FIELD: aeronautical engineering; on-board parachute-type anti-spin systems. SUBSTANCE: spin-recovery system includes container made in form of tube and mounted in parallel relative to tail section of fuselage; it is provided with parachute device and cargo jettisoning mechanism. Container provided with front and tail fairings and open end is mounted on external store by means of attachment units. Pyrotechnic mechanism closed by tail fairing is located on the container outside on its upper tail section at its outlet end. Jettisoned weight of pyrotechnic mechanism is connected with pilot parachute cover through connecting link of parachute device. Pinned link is secured on the container outside under the same fairing. In center portion of container there is longitudinal guide passage of rectangular section where adapter device is arranged. Adapter device consists of two members interconnected by means of shear stud: one member is connected with link of main parachute and other member is connected with load-bearing attachment unit through additional shorter link of parachute device. Two pyro cutters are mounted inside container in its front portion on vertical longitudinal wall; they are mounted in succession in detachable clips. Above-mentioned additional shorter load-bearing link of parachute is passed through these cutters. Beside that, wall of container is provided with upper hole and side auxiliary holes closed by easily detachable covers.
