  • the starting device can activate the engine of the underwater running body, while the underwater running body is enclosed and held under water by the ramp. After the underwater running body is started, the ramp steers the started underwater running body depending on the orientation of the longitudinal axis of the ramp on a first part of its movement path.
  • the propellant deflection unit directs expelled propellant in an outlet direction.
  • This outlet direction of the propellant points vertically or obliquely away from the platform on which the starting device is mounted and from which the underwater running body is started.
  • An underwater running body in the sense of the invention is an unmanned underwater vehicle which converts a fuel into propellant, e.g. burns, the propellant generated ejects and is moved by the expulsion of the propellant through the water.

Particularly in the case of a watercraft as the platform, it is undesirable for the propellant to be expelled into the interior of the

  • the distance between the started underwater running body and the propellant that has left the propellant deflection unit increases during the movement of the underwater running body.
  • This interaction is undesirable in some situations, for example because the movement control of the underwater running body can be made more difficult or an active or passive sonar system of the underwater running body can deliver falsified results.

  • the starting device is designed and arranged in such a way that the following is effected:
  • a propellant that is expelled from the first underwater running body in the first ramp is directed into the associated propellant deflection unit.
  • a propellant that is expelled from the second underwater running body in the second ramp is directed into the propellant deflection unit assigned to the same.
  • the same propellant deflection unit is used for at least two different ramps. This configuration saves space in the same propellant deflection unit.

  • the engine can only be activated, and the underwater running body can only leave the ramp when the locking device is in the release state. Thanks to this configuration, the undesired event is prevented that the engine of the underwater running body is activated, even though the locking device is still in the locking state. This undesirable event can cause the underwater barrel with the engine activated in the ramp is held, for example, because propellant ejected prevents the locking device from being brought into the release state.
  • the starting device comprises a position sensor.
  • This position sensor can positively detect the event that the locking device is in the release state. "Detect positive” means that the position sensor generates a signal when it has detected the event.
  • the starting device is able to activate the engine after the position sensor has discovered that the locking device is in the release state. Thus, the engine is activated in response to the event that the locking device is in the release state.

  • the starting device starts the underwater barrel under water.
  • the outlet opening of the propellant deflection unit can be located above or below the water surface. The expelled and redirected propellant can therefore be expelled above or below the water surface.

  • an actuator is able to open this deflection unit flap. In a preferred embodiment, however, expelled and deflected propellant is able to open the deflection unit flap or to cause it to burst. This preferred embodiment saves an actuator for the deflection unit flap.
  • the deflected propellant can only open the deflection unit flap if the pressure that the propellant exerts on the flap exceeds a predetermined limit.
  • This barrier can be dimensioned such that the flap remains closed when the underwater barrel is started correctly and the pressure of the propellant also contributes to the recoil to expel the underwater barrel. Only when the underwater barrel does not leave the ramp due to a fault does the pressure of the propellant expel open the flap.

  • the ramp actuator is able to pivot the ramp and thus change the orientation of the longitudinal axis of the ramp relative to the platform. This allows the underwater barrel to be started in one of several possible directions. In the case of a watercraft as the platform, the underwater ramp is allowed to be in a hydrodynamically favorable position relative to the direction of travel of the watercraft before the underwater running body is started in the ramp. The ramp therefore causes a relatively low water resistance while the watercraft is moving.

  • outlet A is closed by a closure flap with a predetermined breaking point. The ejection of the blowing agent Tr.1 from the channel Ka causes this closure flap to break at the predetermined breaking point, the fragments are ejected and the outlet A is then open.
  • the expelled propellant Tm.1 definitely opens the flap 14.
  • the expelled propellant Tm.1 opens the flap 14 only when the pressure that the propellant Tm.1 exerts on the flap 14 from the inside exercises, is above a predetermined barrier. As long as the flap 14 is still closed, the pressure of the ejected propellant Tm.1 helps to eject the underwater missile 1.1. At the same time, the desired safety effect is ensured, in particular if the underwater missile 1.1 does not leave the ramp 3.1.
  • the blowing agent Tr.1 together with the fluid from the canister 2.1, exhaust gases and evaporated water is in an outlet direction through the opened outlet A. AR.T ejected outwards.
  • the desired effect that the propellant Tr.1 is ejected to the outside also occurs when the underwater missile 1.1 jams in the canister 2.1 or in the ramp 3.1 and therefore does not leave the ramp 3.1.
  • the entire propellant Tr.1 of the underwater missile 1.1 is discharged to the outside through the chamber Km, the channel Ka and the outlet A, without getting into the interior of the watercraft.
  • the channel Ka rises slightly. Because of this and because the blowing agent Tr.1 is lighter than water, all of the blowing agent Tr.1, which is expelled into the chamber Km and enters the channel Ka, quickly emerges from the channel Ka. No expelled gas collects in the channel Ka. This prevents the watercraft from drawing a bubble trail behind it because propellants or exhaust gases gradually escape from the channel Ka. This effect is particularly undesirable if the watercraft is an underwater vehicle on a diving trip.
  • the chamber Km with the wall 4 and the channel Ka with the wall 5 and the outlet A are assigned to two adjacent ramps 3.1 and 3.2 and belong to a propellant deflection unit.
  • a deflection device for the propellant is assigned to two adjacent ramps.
  • This configuration makes it possible to save space because fewer chambers and channels are required than the starting device comprises ramps.
  • An alternative embodiment is also possible, in which each ramp is assigned its own propellant deflection unit.
  • the design with its own propellant deflection unit saves the need for the rear membrane 8.1, 8.2 of a canister 2.1, 2.2 to be able to withstand the propellant expelled by another underwater missile.
  • the channel Ka extends parallel to the longitudinal axis La.1, La.2 of a ramp 3.1, 3.2.
  • the propellant Tr.1 is ejected parallel to the travel of the underwater missile 1.1 and with a lateral offset.
  • the propellant deflection unit thus deflects the propellant Tr.1 by 180 °. 3 and 4 show two alternative configurations.
  • the second ramp 3.2, the second canister 2.2 and the second underwater missile 1.2 are not shown in FIGS. 3 and 4.
  • FIG. 3 shows an alternative embodiment in a top view
  • FIG. 4 shows a further alternative embodiment in a side view.
  • the watercraft travels in a direction of travel FR (in FIG. 3 in the plane of the drawing and from bottom to top, in FIG.
  • the longitudinal axis La.1 of the ramp 1.1 and the longitudinal axis La.K of the channel Ka likewise lie in the drawing planes of FIGS. 3 and 4.
  • the situations shown in FIGS. 3 and 4 become at least when the underwater running body starts 1.1 manufactured. It is possible that a ramp actuator, not shown, has previously pivoted ramp 1.1 into the firing position shown.
  • the longitudinal axis La.K of the channel Ka is perpendicular to the direction of travel FR
  • the longitudinal axis La.1 of the ramp 3.1 is inclined to the direction of travel FR.
  • the direction of ejection AR of the underwater missile 1.1 thus points obliquely to the front.
  • the deflection angle is preferably between 90 ° and 180 ° (inclusive).
  • the ejection direction AR of the underwater missile 1.1 points obliquely downward and is perpendicular or oblique to the direction of travel FR of the watercraft.
  • the longitudinal axis La.K of the channel Ka and thus the outlet direction AR.T of the blowing agent Tr.1 points obliquely upwards. This prevents blowing agent Tr.1 from accumulating in the channel Ka and bubbles escaping and therefore the watercraft pulling a bubble trail behind it.

Abstract

La présente invention concerne un dispositif de démarrage destiné à démarrer un corps mobile sous-marin (1.1) à partir d'une plateforme, en particulier d'un véhicule marin, ainsi qu'un procédé d'utilisation d'un tel dispositif de démarrage. Le dispositif de démarrage comprend une rampe (3.1), qui s'étend le long d'un axe longitudinal (La.1) de rampe, et une unité de déviation (4, 5, Km, Ka) de fluide moteur. La rampe (3.1) entoure sous l'eau un corps mobile sous-marin (1.1) pourvu d'un moteur (Tw.1). Le dispositif de démarrage active le moteur (Tw.1), lequel éjecte après cela un fluide (Tr.1) moteur. L'unité de déviation (4, 5, Km, Ka) de fluide moteur dévie le fluide (Tr.1) moteur éjecté dans une direction de sortie (AR.T). Cette direction de sortie (AR.T) du fluide moteur (Tr.1) est opposée de manière perpendiculaire ou oblique à la plateforme.
