The invention relates to an
impact reducing
tail-section linear explosion separating device for a small-
diameter assisted
takeoff rocket. The
impact reducing
tail-section linear explosion separating device comprises a
detonator, a split type detonating connector, an
impact reducing shell, an explosive fuse, a glass protective cover and
energy absorption pads. The split type detonating connector comprises a detonating mounting seat, transition studs and an explosion connector, the impact reducing shell comprises an upper shell, impact reducing pads and a lower shell, and a particular connection relation includes that the impact reducing pads are placed between an end frame of the upper shell and an end frame of the lower shell and are fixedly connected with the upper shell and the lower shell by the end frame of the upper shell and the end frame of the lower shell; an outer mounting surface of the protective cover and the inner surface of the lower shell are matched with each other to be radially positioned, and a positioning ring of the protective cover and a positioning surface of the lower shell are matched with each other to be axially positioned; the explosion connector is connected with the protective cover and the lower shell, the detonating mounting seat is mounted on the end frame of the upper shell, lower threaded rods of the transition studs are screwed into the explosion connector, and upper cylinders of the transition studs are connected with the detonating mounting seat. The impact reducing
tail-section linear explosion separating device has the advantages that the separating device is small in structure dimension, convenient to
mount and check and high in separation efficiency and safety performance, and has an excellent heat environment, and separation impact can be greatly reduced.
