Definitions

  • the present invention has for its object to avoid suchiault
  • the torpedo is provided with one or more comparatively large horizontal-rudders, here below referred to as ,steering rudders, forsteeringof the torpedo during the fall, which rudders are so constructed andzarrang ed'that they arereleased fromthe torpedo when thesamestrikes the water, preferably thereby that their connections are broken ;or released "by the impact against the water.
  • ,steering rudders forsteeringof the torpedo during the fall, which rudders are so constructed andzarrang ed'that they arereleased fromthe torpedo when thesamestrikes the water, preferably thereby that their connections are broken ;or released "by the impact against the water.
  • the steering rudders preferably aredivided in vtwo parts, with one rudder plane on each side of the tail of the torpedo, and more or less balanced; 1 I
  • the movement of the steering rudders' iseffected by means of .an auxiliary-rudder, preferably arranged on'the side of the torpedo, and the weight of which is balanced, which rudder under the influence of the air current during the 'fall of the torpedo adjusts itself at the tangent to the path of fall-and by a deviation of thelongitudinal axis of they torpedo from this tangent acts on' a" steering machine, for, the steering ruddersin such way that the rudders are moved in the direction so as to' bring the torpedo back in the position with its longitudinalaxis at the-tangent to the path.
  • the auxiliary rudder on the steering machine is effected by meansof an air slide or the like which is connected with the auxiliary rudder and at the relative movement between the rudder and the torpedo controls the ad-, mission of. pressure medium to the steering machine.
  • a separate steering machine may be provided for the steering rudders, but preferably the steering machine for the depth rudders of the torpedo is used, this machine being under the influence of the auxiliary'rudder during the fall 55 r of the torpedo, but being brought under the influence of the usual depth steering apparatus when the torpedo has entered the water.
  • This change-of the steering machine suitably may be effected bychanging a valve or the like by means
  • the steering rudders may, for example, be 'provided with a fork engaging the aft edge of the depth'rudder, or a projection on this rudder.
  • 'A locking device' may lock the auxiliary rudder in" its zero position (no air admitted to the steering machine) until the torpedo has fallen 8 a distance sufiicient to befree'from disturbing ircurr'ents from the flying machine.
  • This may suitably be efiected by means of a pm which prevents turning ;of the auxiliaryrudder and which is connected with the flying machine by a line or wire which disengages the pin when the torpedo has fallen a predetermined distance.
  • the steering rudders with devices also may be arranged in conection with a resistance body for retardation of the torpedo upon its entering the water, in which case a quantity of pressure air sufiicient for the operation of the steering: rudders is stored, in this resistance body.
  • the drawing illustrates an example of an embodiment of the invention, where the steer- .a torpedo illustrating a steering arrangement constructed in accordance with the present invention
  • the steering machine is changed so that it is operated by means of another slide 19 through the slide rod 20 by the usual depth steering devices.
  • the changing of the steering machine is effected by means of the, changing or distribution valve 21, to which pressure air for the operation of the steering machine is conducted from the pressure regulator, and which valve is provided with air and exhaust conduits to the slide 18 connected with the auxiliary rudder as'wellas to the slide 19 connected with the depth steering devices.
  • the conduits to the slide of the auxiliary rudders are open and the conduits to the depth steering slide .closed.
  • the changing is effected by means of the impact plate 22, which during the fall of the torpedo projectsbeyond the shell of the torpedo as shown in full linesybut,
  • the auxiliary rudder may be locked'by means of the pin 23 until the torpedo has fallen a distance sufiicient to avoid any danger of the auxiliary rudder being" influenced by air cur-
  • the pin 23 is inserted into the bearing 24 for the shaft of the auxiliary rudder in such way, that a turning of the rudder is prevented, and is connected by a line 25 with the flying machine so that the pin is released by the line when the torpedo has fallen the desired distance.
