Abstract

A smoke launcher system comprises a plurality of differently oriented launch pots and assembled in a three dimensional fan shape to form a steerable launch unit as a whole. The launch unit (1) is hinged, so that it can be pointed in the direction, to the side of a hatch cover (2) of the roof of the vehicle located in the closed state of the hatch inside the vehicle, the hatch cover (2) being able to be tilted to adjustable angles, about a horizontal axis, for the height pointing of the launch unit (1). The pointing towards the unit (1) is possible by its rotation about an axis perpendicular to the panel (2) in a joint (4) connecting the unit (1) to the inner side of the panel (2). Applicable to the armament of armored vehicles.

Description

The invention relates to a smoke-thrower system of an armored vehicle,

  comprising a plurality of different orientation pots or launch tubes and assembled in a three-dimensional fan shape to constitute an orientable launching unit as a whole, A system of this type is known from the document

DE 37 05 700 C2.

  In order to avoid the possibility of radar location of the vehicle on which it is installed, such a smoke-throwing system must be placed naked on the vehicle.

  outer skin of this vehicle.

  From the foregoing, the invention aims to

  create a smoke-generating system, of the generic type indi-

  which, at least in the non-activated state, does not have an adverse effect on the possibility of locating the vehicle by radar, can properly and simply be pointed in height and in direction and can also be recharged at the state protected against attacks. he

  must be possible in addition to firing

  target, different launch pots.

  A fundamental solution is provided to this

  problematic by a smoke-generating system which is essential

  characterized in that the launching unit is hinged, so that it can be pointed in the direction, on the side of a roof hatch panel of the vehicle located in the closed state of the panel inside the vehicle, the hatch cover which can be tilted to adjustable angles of rotation or tilt about a horizontal axis for pointing the height of the

launch.

  Where, according to another characteristic, the hatch cover is placed in a lateral part of the

  vehicle near a member of the crew, he

  Just simple to recharge the different pots of launch while the launch unit is inside the vehicle. Simply turn the unit to the side, to the retracted position, so that it is better accessible to the servant, who can

to be the driver of the vehicle.

  With the execution according to the invention, the pointing in height is obtained by the controlled tilting of the hatch panel. Thanks to this solution, it suffices

  only one setting control to open and close the pan-

  on the one hand and for pointing in

  the entire launch unit on the other hand.

  The pointing in direction is done by rotating

  in a joint with a single axis and through which the launching unit is

  attached to the roof hatch panel of the vehicle near

  mity of the tilting axis of this panel. The single axis

  this joint is perpendicular to the plane of the

hatch.

  In case the smoke shells have to be fired

  one by one the different launching pots, we can

  kill an individual pointing direction for each pot to use through the single-axis articulation of the launch unit. When pointing in height is also desired, it can be done by controlled switching

hatch cover.

  The different pots are arranged in the launch unit with mutual offsets such, in height and laterally, that a smoke screen is created in the case of a simultaneous activation for the shooting of all

  Launch pots belonging to the unit.

  In the case of phased ignition of

  smoke generation pots, one can, by a

  variation of the tilting angle of the panel of

  the rotation of the launch unit, carried out between the different ignitions, to mask in a targeted way a surface which is larger than that which can be masked by the collective simultaneous ejection of smoke

of all the pots.

  Other features and advantages of the

  will become clearer from the description

  which follows a non-limiting embodiment, and the accompanying drawings, in which: - Figure 1 is a side view of an armored vehicle; - Figure 2 is a section taken in the direction of the length of the vehicle and passing through the part of its roof including the hatch panel and the unit of

  launch, which is not shown in section and

  cupe a hidden position of drawdown; - Figure 3 shows the launch unit by

  a view similar to Figure 2, but in the extended position

  due fire; - Figure 4 is a top view of the unit

  in the folded-down or retracted position, the

  hatch being shown with a cut-out

  putting this view from above; and FIG. 5 shows the launching unit in a representation similar to FIG. 4, but following a rotation towards the side to a reloading position.

  The launch unit 1 itself is

  laterally rotatable on a panel 2 serving to

  sea a hatch formed in the roof of the vehicle, the

  panel that can be opened by swinging out

  laughing. When the panel 2 is closed, the launch unit 1 is masked and protected. Thanks to this masking, the unit

  1 does not represent an increased risk of loca-

  Radarization of the armored vehicle. To obtain a smoke shooting position, the hatch cover 2

must be open.

  The various pots or launch tubes 3 are rigidly assembled together in a three-dimensional fan shape to form the launch unit 1. The orientation of the various pots 3 in the unit 1 is such that when smoke shells are

  taken simultaneously from all the pots 3, a surface

  determined will be masked by the smoke. By changing the tilting or rotating angle of the panel 2, the distance and depth of this panel can be changed.

face masked by smoke.

  Rotational mobility of the unit compared

  at the hatch cover 2, that is to say, the mobility in

  lateral or pivotal position, is provided by a

  link 4 mounted on panel 2 in the area of his articu-

  on the roof of the vehicle and having an axis of rotation

  perpendicular to the hatch cover 2. The launch unit 1 in itself rigid - is only

  maintained in the bearing 4 by an eye 5 formed on it.

  For opening, closing and flip-flop

  under control of the hatch cover 2, it is

  tilted by one side on the roof of the vehicle in

  6. The tilting movement may be produced by any adjustment control, which may be

  constituted for example by a hydraulic cylinder 7 which has

  pull a tilting lever 8 of the panel 2.

  When the launching unit 1 is used for shot-by-shot, the score is made each time by the prior definition of the angle of

  tilting the hatch cover 2 on the one hand and the

  preliminary finishing of the angle of rotation or swivel-

  Unit 1 on the other hand. By such maneuvers for each shot, one can very well vary the size of the space to be masked by the smoke and, in particular, enlarge this space considerably in comparison with a simultaneous collective shooting of smoke of all the pots

3 of the launch unit 1.

  The refilling of pots 3 is done under

  tection, the hatch panel 2 being closed. In order for the pilot to perform such reloading in a simple manner, the launch unit 1 is provided in an area adjacent to the location of the pilot or another member of the

  the crew. In order for the pilot to effectively

  load the launch pots 3 conveniently, given the limited space available in the vehicle, the whole unit i can be turned in the landing 4 for this

  operation, to the pilot or another servant (Figure 5).

  The device according to the invention, which has just been described solely by way of example, makes it possible to achieve in a really simple manner, in particular the

  following benefits, gathered again.

  - The risk of radar localization of the vehicle is diminished by the fact that the smoke emission system is

  hidden during the time it is not used.

  - The launch unit 1 can be pointed in height and

in direction.

  - A targeted shot by shot is possible thanks to the possibility of pointing in height and in the direction of

the launch unit 1.

  - The area likely to be masked by the smoke can be enlarged by coordinated shots of

the launch unit 1.

  - Launch pots 3 are refillable in a protected position and with a specially designed orientation

for reloading.
