FIELD: aeronautical engineering; control systems of doors discharging extinguisher to fire area, as well as other devices for discharge of loose cargoes through hatches in bottom of seaplanes or hatches in fuselages of landplanes, helicopters and other flying vehicles. SUBSTANCE: device has lock drive part made in form of combination of actuating lock hydraulic cylinders 7, locks 22 for locking doors 5 in closed position provided with low-power drive 19 and synchronization sensor 30; each lock is arranged inside each cylinder in its top portion articulated to tank structural members. Lower rod portions 32 of cylinders 6 and 7 are provided with pyrotechnic connectors 27 and are articulated to doors 5. Each lock cylinder 7 is partially filled with ferromagnetic fluid. Device has lock drive part made in form of combination of actuating lock cylinders 6 and lock cylinders 7; each lock 22 for locking doors 5 in closed position has swivel member or cable run interconnecting locks 22 and connecting them to control member. Locks 22 are arranged inside cylinders 6 and 7 and swivel member is located outside in their top portions secured to tank structural members. Lower rod portions 16 and 32 of cylinders 6 and 7 are provided with pyrotechnical connectors 27 and are articulated to doors 5; each lock cylinder 7 is partially filled with ferromagnetic fluid. EFFECT: enhanced reliability of system due to avoidance of contact of highly loaded members of locks with extinguisher; simplified construction due to avoidance of labour-consuming line of control of extinguisher discharge door lock members; possibility of employment of single-link pyrotechnical system for emergency discharge of extinguisher; reduced mass of structure. 3 cl, 9 dwg |
