Definitions
- the present invention relates to a torpedo launch device, in particular for launching torpedoes from a surface vessel.
- Pneumatic torpedo launch devices which substantially comprise a launch tube, into which the torpedo is inserted; and a system for feeding compressed air into the rear of the launch tube to fire the torpedo.
- the compressed air is contained in a highpressure cylinder.
- compressed air must be made available on the launcher; maintaining the given compressed-air pressure may pose problems; and, finally, the pneumatic system calls for routine maintenance.
- Number 1 in Figure 1 indicates as a whole a launch device for launching a torpedo 2.
- Launch device 1 comprises a substantially cylindrical launch tube 3 having a front muzzle end 3a and a rear end 3b; and a expulsion assembly 4 housed inside launch tube 3, close to rear end 3b.
- torpedo 2 is fitted at the rear with a shank 9 with a spherical end 9a.
- Expulsion assembly 4 comprises a base disk 5 connected to rear end 3b of launch tube 3; a thrust disk 8 connectable releasably to shank 9 of torpedo 2 housed inside launch tube 3; and an explosive-actuated bag 7 interposed axially between base disk 5 and thrust disk 8.
- Base disk 5 is preferably connected to rear end 3b of launch tube 3 by a fast-fit, e.g. bayonet, connecting device not shown.
- Bag 7 is substantially cylindrical, and has a rear base wall 11 secured to base disk 5 by fast-fit, e.g. bayonet, connecting means not shown. At rest, as shown in Figure 1 , bag 7 is folded accordion-fashion and lashed in place by a calibrated-release binding not shown.
- fast-fit e.g. bayonet
- Bag 7 is fitted with and inflated by an explosive gas generator 10.
- Bag 7 also comprises a relief valve 12 and a safety valve 13 housed in respective seats in base disk 5 to communicate with the outside of launch tube 3.
- Thrust disk 8 is connected releasably to torpedo shank 9 by a lock device 14 shown in Figures 2 and 3 .
- Lock device 14 substantially comprises a gripper 16 having a central body 18 housed in axially sliding manner inside a central cavity 17 of thrust disk 8, and to which are hinged two substantially L-shaped jaws 19, which cooperate with shank 9 of torpedo 2 and are held in the closed position gripping the shank by the walls of cavity 17.
- Central body 18 has an axial push-rod 22 which cooperates with spherical end 9a of shank 9 of torpedo 2; and central body 18 is connected, by an actuating rod 20 fitted through thrust disk 8, to a pressure sensor plate 21 facing bag 7.
- a first spring 48, externally coaxial with actuating rod 20, is compressed between plate 21 and thrust disk 8; and a second spring 49, externally coaxial with push-rod 22, is compressed between central body 18 and jaws 19 (when closed) of gripper 16, so as to push the jaws into the open position.
- Lock device 14 also comprises a number of stop assemblies 24 housed in respective radial holes 23 formed in, and communicating with central cavity 17 of, thrust disk 8.
- Each stop assembly 24 substantially comprises a rod 25 which interacts with central body 18 of gripper 16; and a push-rod 26 connected telescopically to rod 25, and which clicks inside a respective seat 27 in launch tube 3 to axially lock thrust disk 8.
- rod 25 comprises a tubular portion 28 (partly removed in Figure 2 ) housing in sliding manner one end of push-rod 26 forming a plate 29.
- Push-rod 26 is subjected to the action of two counteracting springs 30, 31 : spring 30 is compressed axially between rod 25 and plate 29 of push-rod 26 to push push-rod 26 outwards, i.e. towards the wall of launch tube 3, and rod 25 inwards, i.e. towards cavity 17; and spring 31 is compressed between an inner shoulder of hole 23 and plate 29 to hold push-rod 26 in the withdrawn position inside hole 23.
- Rods 25 of stop assemblies 24 and central body 18 of gripper 16 have respective bevels 34, 35, which interact with one another, when central body 18 is inserted inside cavity 17, to push rods 25 outwards.
- Thrust disk 8 and torpedo 2 are guided inside launch tube 3 by a number of inner longitudinal guides 40, 41 inside the tube ( Figure 4 ). More specifically, launch tube 3 has four grooves 40 spaced 90° apart and engaged in sliding manner by respective fins 42 on torpedo 2, and by respective guide fins 44 on thrust disk 8; and four grooves 41 spaced 45° from grooves 40 and engaged in sliding manner by respective outer radial projections 45 on thrust disk 8 ( Figure 5 ).
- grooves 41 dead-end on the side facing end 3a of tube 3; and shock-absorbing stop devices 46 are provided at the end of grooves 41 to arrest thrust disk 8.
- a bayonet system (not shown) conveniently permits extraction of thrust disk 8 from end 3a of launch tube 3.
- Launch device 1 operates as follows.
- torpedo 2 is configured for launching from the tube by fitting on interface shank 9.
- Thrust disk 8 is then fixed onto shank 9 of torpedo 2 by means of lock device 14.
- lock device 14 is shown in the deactivated position.
- shank 9 pushes push-rod 22 of central body 18 axially to back up central body 18 inside cavity 17; jaws 19 close onto shank 9 by interaction with the walls of cavity 17; and bevels 34, 35 push stop assemblies 24 outwards.
- Torpedo 2 and thrust disk 8 as a whole are then inserted inside launch tube 3 through rear end 3b, and are locked inside the tube by the ends of push-rods 26 clicking inside respective seats 27.
- Base disk 5 already fitted with bag 7, is fitted inside rear end 3b of launch tube 3, as shown in Figure 1 .
- launch tube 3 is ready for launching.
- gas generator 10 is activated by a control signal.
- Push-rods 26 are thus withdrawn by springs 31 to release thrust disk 8 from launch tube 3.
- thrust disk 8 advances to expel torpedo 2 from launch tube 3, and comes to rest against shock-absorbing stop devices 46 at the end of launch tube 3.
- launch device 1 is restored by :
