Shoot error compensating method and device and weapon system computer

Abstract

A method and a device (20) are described for compensating firing errors of a gun having a weapon barrel (10.2). Firing errors, which are caused by static gun geometry errors, which influence the position of the weapon barrel (10.2) during aiming of the weapon barrel (10.2) at aiming values, are compensated. For this purpose, the weapon barrel (10.2) is brought into measurement positions in steps by rotation around an axis. Using suitable devices of a measurement facility, an intended value, which describes the intended position of the weapon barrel (10.2), and an actual value, which describes the actual position of the weapon barrel (10.2), are detected at each measurement position. A difference between the actual value and the intended value, defined as an error value, is then calculated. Correction values are established from multiple error values of the measurement positions and the correction values are taken into consideration during later aiming of the weapon barrel (10.2). The method and the device (20) are used for a weapon system (10) which has a system computer (10.4) for calculating aiming values for aiming a weapon barrel (10.2) of a gun (10.1) of the weapon system (10); the system computer (10.4) has a data input (24) for data which is made available, this data being intended for the purpose of being taken into consideration during the calculation of the aiming values, in order to compensate aiming errors, which are caused by static gun geometry errors and which influence the position of the weapon barrel (10.2).

Description

(1) Technical field [0001] The invention relates to a method and device for compensating shooting error of a gun with a barrel of a weapon gun in a weapon system, and the shooting error is caused by a geometric error of a static gun; and a system computer for a weapon system. (2) Background technology [0002] Firearms consist of many individual parts which are rigidly or flexibly connected to each other. The dimensional accuracy of these individual parts cannot be manufactured very precisely, but has a certain manufacturing tolerance and / or deviation compared with the theoretically determined size, and a fixed assembly tolerance that deviates from the predetermined position relative to each other occurs during assembly. The total deviation causes each gun to have a certain deviation from the ideal geometry, which is called the gun geometric error. Such gun geometric errors consist of many kinds of errors. For example, the geometric error of the gun shows that the azimuth ...

AI Technical Summary

Problems solved by technology

Existing methods cannot measure all types of gun parameters

Measurements also cannot be automated and are therefore time consuming; as a result, only a few measurements can be taken at each measurement location for the weapon gun barrel, so random measurement errors cannot be eliminated

Such measurements are not only time-consuming, but also require a lot of manpower, making the measurements very expensive

In addition, some surveyors must be located in the muzzle area of ​​the weapon gun barrel for measurement work, which is quite dangerous; to measure a gun with a large elevation angle and a long barrel of the weapon gun, the surveyor must use lifting equipment to rise to the bottom of the weapon gun barrel. Can only be measured in the muzzle area of ​​the gun or on the ladder
