Definitions
- the invention relates to an optronic viewfinder with a flexible shield comprising means for detecting the shielding.
- a viewfinder equipping an armed land vehicle, such as a tank, is conventionally provided with an optronic device incorporating detection equipment such as an infrared camera, a video camera, a thermal camera, a laser rangefinder, etc.
- an optronic device is mounted on a two-axis orientation platform which makes it possible to orient the device in a site and in a bearing.
- the viewfinder at the command post is usually a panoramic viewfinder located on an upper part of the tank's turret to provide the tank commander with as wide a field of view as possible.
- This viewfinder is very exposed and must be protected against external aggressions and more particularly against projectiles (bullet impacts, shrapnel, debris, etc.) and is equipped for this purpose with a ballistic armor.
- the sight of the firing station meanwhile, is located near the weapon.
- the sight of the firing station benefits from a limited angle of view centered on the axis of the barrel of the weapon. This allows to house the viewfinder closer to the barrel between armored walls of the tank.
- the sight of the firing station is not itself equipped with a shield.
- the two viewers can be identical from an optronic point of view, they have different mechanical structures adapted to the onboard weight, including the motorization and the bearing for the rotation of the optronic viewfinder.
- the bearing of the sight of the firing station generally has a smaller diameter to limit the friction and to facilitate the active stabilization of the sight by the control of the motorization (in the visor of the position of head of tank, the frictions resulting from the use of a bearing of large diameter are not a problem to ensure the active stabilization of the viewfinder because they are compensated by the inertia provided by the mass of the shield).
- the object of the invention is to reduce the development and maintenance costs of the viewfinders equipping, in particular, armed land vehicles.
- an optronic viewfinder with adjustable shielding comprising an optronic device, a bearing comprising a rotary part carrying the optronic device, rotary drive means of the rotary part, control means adapted to drive the drive means, and a modulable shield adapted to be carried by the rotating part of the bearing.
- the optronic viewfinder comprises shielding detection means on the rotating part, the detection means being connected to the control means which are arranged to adapt the control of the drive means according to the result of the detection.
- these viewfinders are today generally different and include in particular an orientation platform different and / or different drive means and / or different control means for controlling the drive means. It is therefore necessary, to equip such an armed vehicle, to develop two different viewfinders. It is also necessary to store and make available these two different types of viewfinders to ensure maintenance operations.
- the optronic viewfinder of the invention is equipped with a modular shield which can be installed or not on the optronic viewfinder.
- the detection means of the optronic viewfinder can detect the presence or absence of the shield and adapt the control of the drive means according to the presence or absence of a shield on the viewfinder.
- two similar viewfinders comprising the same platform, drive means and identical control means, the viewfinder of the control station being equipped with a shielding contrary to that of the firing station. We therefore reduce the development cost of these viewfinders since it is no longer necessary to design two viewfinders.
- an armed land vehicle with at least one weapon, a firing station from which the weapon is fired, a command post from which operations are performed such as control or observation operations, the control station being provided with a first optronic viewfinder on which the modular shielding is installed, the shooting station being provided with a second optronic viewfinder on which the modular shielding is not installed.

- the use of the first set of values 30 or the second set of values 31 is defined by the control means 14 of the programmable electronic card 12 as a function of the result of the presence detection of the shielding 7 transmitted by the detection means. 24.
- the first and second series of values 30, 31 of the adjustment parameters are predetermined to take into account the difference in mass and inertia between a viewfinder equipped with a modular shield 7 such as the first one. optronic viewfinder 4a and a viewfinder not equipped with a modular shield 7 such as the second optronic viewfinder 4b, differences in mass and inertia being significant because of the relatively high mass of the modular shielding.
- the first and second series of values 30, 31 of the adjustment parameters also take account of the friction at the rolling elements of the bearing, friction whose influence on the motorization is greater in the viewfinder not equipped with a flexible shielding. .
- control program used to control the electric motor 13 of the first optronic viewfinder 4a and that of the second optronic viewfinder 4b is a single parameterizable program.
- the bearing comprises rolling elements consisting of balls of large diameter relative to an inner diameter of the bearing.
- the ratio between the inside diameter of the bearing 7 and a diameter of one of these balls is here between 15 and 35, and is advantageously close to 25.
- the inside diameter of the bearing 7 is thus typically 10 inches or 25.4 cm for an outside diameter of 11.5 inches or 29.21 cm, while the balls typically have a diameter of three eighths of an inch, or about 9, 52 mm. With such dimensions, the ratio between the inside diameter of the bearing 7 and the diameter of the balls is 25.7.
- the relatively large diameter of the balls relative to the internal diameter of the bearing 7 makes the bearing 7 perfectly adapted to the mass and the large inertia of the first optronic viewfinder 4a of the invention which is equipped with the modular shielding 7.
- the strong inertia is favorable to the stabilization of the position angular deposit, and makes it possible to compensate for the significant friction associated with the balls of large diameter of the bearing 7.
- detection means which detect an open circuit and a short circuit at the configuration pins of a viewfinder connector
- the invention naturally applies to completely different detection means. It is for example possible to equip the viewfinder with one or more sensors (proximity sensors, etc.) directly detecting the presence of the shield, said sensors being connected to the control means. It is also possible to detect the presence of the shield according to the efforts that the engine must provide to move the viewfinder (measurement of the current consumed for example) or to provide that the viewfinder control program requires a predefined action of the operator allowing to indicate whether the viewfinder is positioned at the position of the tank commander or the shooter's post.
