Firearm for low velocity projectiles

a projectile and projectile technology, applied in the direction of sighting devices, weapon components, aiming means, etc., can solve the problems of not being able to accurately detect the target, the sight may only be adjusted relative to the longitudinal axis of the sight, and the probability of a proper hit is pretty bad in practice for such firearms, so as to improve the probability of a proper hit

Benefits of technology

[0013] It is, therefore, an object underlying the invention to improve a firearm of the type specified at the outset, such that the above-mentioned disadvantages are avoided. In particular, a firearm for low velocity projectiles shall be made available which makes a high rate of hits possible, even when target objects shall be hit which are located at highly differing distances and / or heights and / or move at highly different speeds.

Problems solved by technology

The probabilities to hit a target (so-called hit images) are, therefore, pretty bad in practice for such firearms, in particular when the target object is at a different height as compared to the gunner.
These prior art aiming instruments have the disadvantage that the line of sight may only be adjusted relative to the longitudinal axis of the sight within a relatively small range.
For grenade weapons, this is often insufficient when these weapons are used at highly differing distances relative to the target object or with high differences in height between the gunner and the target object.
This prior art apparatus is exclusively intended to be used for rifles, and, therefore, it has the disadvantage that it necessitates a mechanical adjustment, even for small attack angles.
For large attack angles, as may occur for grenade launchers, this would result in unacceptable long adjustment times.

Embodiment Construction

[0046] In FIG. 1, reference numeral 10 designates a combat situation within an inclined terrain 12. A target object 14, for example a vehicle, is located at a higher position. A firearm 16, for example a grenade launcher, is located within terrain 12 at a relatively lower position.

[0047] According to FIGS. 1 to 5, firearm 16 is provided with a barrel 18 having a longitudinal or bore axis 20. Barrel 18 is provided to launch low velocity projectiles, in particular grenades, having a large diameter of, for example, 30 to 150 mm. Due to the lower muzzle velocity of, for example, 50 to 200 m / s, the trajectory of these projectiles is substantially curved, for example like a parabola.

[0048] A sight 26 is mounted on barrel 18 via a joint 22. Sight 26, for example, is a sight telescope. Sight 26 has a high resolution and, therefore, only covers an angular range that is smaller as would be required in the particular combat situation 10.

[0049] Sight 26 is part of a fire control system 24. F...

Abstract

A firearm for low velocity projectiles has a barrel for launching the projectiles, and a fire control system. The fire control system comprises a sight having a longitudinal axis, sensors for sensing data of a target object, and first means for adjusting a line of sight of the sight relative to the longitudinal axis of the sight. The adjusting is effected by a predetermined angle as a function of the data. Further, second means are provided for adjusting the longitudinal axis of the sight relative to a bore axis of the barrel.

Description

FIELD OF THE INVENTION [0001] The invention, generally, is related to the field of firearms for low velocity projectiles, in particular grenade launchers and mortars. [0002] More specifically, the invention is related to a firearm for low velocity projectiles having a barrel for launching the projectiles, and a fire control system, the fire control system comprising a sight having a longitudinal axis, sensors for sensing data of a target object, and first means for adjusting a line of sight of the sight relative to the longitudinal axis of the sight, the adjusting being effected by a predetermined angle as a function of the data. BACKGROUND OF THE INVENTION [0003] In the context of the present invention, the term “firearms for low velocity projectiles” is to be understood to comprise portable firearms with projectiles of about 30 to about 150 mm diameter. Such firearms are, for example, grenade weapons like grenade launchers or grenade accessories for portable firearms, all being ca...
