Filed:

Dec 29, 1981

Appl. No.:

6/335436

Inventors:

Edgar R. Terry - Richmond VT
Joseph A. Hudock - Shelburne VT

Assignee:

General Electric Company - Burlington VT

International Classification:

F41G 500

US Classification:

89 41SM

Abstract:

A feature of this invention is the provision of a dispersion control which continually displaces the aimpoint of the gun system about its nominal aimpoint in a pattern which is determined by the future slant range and the desired ballistic pattern for the specific target.

International Classification:

F41D 704

US Classification:

89 41A

Abstract:

A system is provided for matching the auto- and cross-correlated components of error and constant and/or range-dependent biases with appropriate values of ballistic dispersion or random errors in order to decouple the gun system from the highly auto- and cross-correlated tracking and/or gun-order errors associated with high firing-rate multibarrel guns. This angular ballistic dispersion--artificially induced to some preset value or continuously adjusted during the tracking and/or firing interval--maximizes the probability of a preassigned number of hits on target. The system embodies (1) a logic for controlling the angular ballistic dispersion for the engagement conditions, (2) a control system which, using this logic, provides power to a mechanism which increases or decreases the gun angular dispersion in response to externally generated command signals, and (3) a mechanical dispersion control mechanism for positioning the individual barrels of the multibarrel gun system and thereby achieving the desired angular ballistic dispersion.
