  • the blade 36 removes a seal, for example, a cap, which, in the inactive state, i.e. when the torpedo is in storage, seals the feed line 35 .
  • the electric energy for the drive motor 23 is supplied via an interface 39 on the outer hull of the battery section 30 .
  • the drive motor 23 is controlled so that the adjusting screw 19 drives the opening spike 12 through the sealing membrane 5 , so that the systems of the torpedo connected to the pressure reservoir 2 are pneumatically actuated.
  • the position signals 40 of the position sensors 26 , 27 , 28 can also be transferred via the interface 39 , so that the position of the locking device 5 can be verified without opening the torpedo. Thereby, for the purposes of regular maintenance, a test run can also be performed, in which the drive motor 23 is driven in the opposite rotational direction to that of the actuation operation and opening the locking device 1 .
  • an evaluation unit 41 connected to the interface 39 is provided in the battery section 30 , which processes the position signals 40 of the locking device 1 and can be controlled via the interface 39 .
  • the torpedo contains further pneumatically activatable mechanisms or systems, the respective pressure reservoirs of which are opened on activation.
  • a locking device 1 in accordance with the invention is also connected to these pressure reservoirs according to FIG. 1 to FIG. 3 and FIG. 5 , so that the torpedo is immediately and reliably operational, even after a longer storage period.
  • the torpedo incorporates a pneumatically activatable mechanism to extend a radio antenna designed in the form of a telescopic antenna.
  • a telescopic cylinder of a telescopically extendable radio antenna of the torpedo is supplied from a pressure reservoir, which is sealed with a locking device 1 as described in FIGS. 1 to 3 . Once the opening spike 12 of the locking device pierces the sealing membrane 5 and thus releases the working gas from the pressure reservoir, the operating pressure connects through to the pressure chamber of the telescopic cylinder of the radio antenna, so that the radio antenna is extended out from the torpedo.
  • the telescopic cylinder is of such a length and consists of an appropriate number of telescopic tubes inserted into one another so that the radio antenna can break the surface of the water while the torpedo is traveling close to the surface of the water.
  • the torpedo can establish a radio connection to an external carrier platform or, for example, receive navigation information via GPS, which is fed to its control unit and is taken as a basis for its navigation.
