DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to correcting alignment errors between the mounts for mounting fire control devices and guns of a weapon system.
In its more particular aspects, the present invention specifically relates to correcting alignment errors between the mounts for mounting fire control devices and guns of a weapon system, and thus, generally relates to the field of detecting and measuring as well as compensating for errors. In particular, the present invention is directed to determining and correcting errors which result from mechanical or dimensional manufacturing tolerances as well as changes in the mounts and seatings of fire control devices and associated weapons or guns. The determination and correction of such errors is carried out for the purpose of accomplishing a precise mutual alignment of the fire control devices and the associated weapons or guns relative to each other.
The interaction or cooperation of fire control devices or systems with one another, of fire control devices or systems with weapons or guns controlled thereby, and of weapons or guns with one another, wherein these systems are or have to be coordinated in relation to one another, is generally impaired by so-called alignment errors. Alignment errors are errors which include a deviation from a defined (common) geometry, regardless of whether these errors occur during construction or after construction due to changes in the support base, as can be the case, for example, on ships.
In order to rectify alignment errors caused by mechanical inaccuracies, these errors must first be measured, then corrected and appropriately subsequently remeasured in order to detect time-dependent errors and possibly corrected.
SUMMARY OF THE INVENTION
Therefore, with the foregoing in mind it is a primary object of the present invention to correct alignment errors between the mounts for mounting fire control devices and guns of a weapon system in a manner not afflicted with the drawbacks and limitations of the prior art.
Another and more specific object of the present invention is directed to correcting alignment errors between the mounts for mounting fire control devices and guns of a weapon system while rectifying alignment errors in a comparatively simple manner and in a manner such that the alignment error rectification can be unlimitedly frequently repeated.
It is a further significant object of the present invention to correct alignment errors between the mounts for mounting fire control devices and guns of a weapon system while rendering possible detection and correction of time-dependent errors including comparatively slow variations with time.
Another still important object of the present invention aims at correcting alignment errors between the mounts for mounting fire control devices and guns of a weapon system while taking due account of dimensional deviations in the system components from a desired or ideal geometric configuration during servo control of the aforementioned mounts.
Now in order to implement these and still further objects of the invention, which will become more readily apparent as the description proceeds, the method of the present development is manifested, among other things, by the features that,
(a) a target measuring sensor is attached to a gun which is mounted at a servo controlled mount, and the target measuring sensor line of sight is aligned to the line of sight defined by the gun;
(b) the guns containing target measuring sensors are aimed by means of a target tracking device and target tracking devices are aimed at a common measuring target or
(b') the guns containing target measuring sensors and aiming means, as well as target tracking devices are aimed at a common measuring target;
(c) a deviation is detected between the position of the common measuring target and the position of the target measuring sensor line of sight at the target measuring sensor of the gun which is controlled by the target tracking device, or
(c') a deviation is detected between the position of the co
