Abstract
In a device for carrying out quality test firings with a gun barrel (1), a mount (2) and an automatic adjusting arrangement (4, 5, 6) for resetting the barrel (1), a given directional setpoint value is compared with the actual direction value. While the actual value is derived from a mirror (3) attached to the barrel (1) itself, the setpoint value is produced by a frequency-modulated laser beam (.nu.) from a source mounted nonvibratingly and separately from the barrel (1) and its mounting (2). By this separation, the hit dispersion due to the mechanical components is reduced to a minimum. This device is of particular usefulness in the development and quality control of small-calibre ammunition.
Claims9
A device for carrying out test firings for determining the quality of ammunition, comprising:
- means for mounting a barrel for relative movement with respect to a foundation;
- means for firing the ammunition from said barrel;
- and
- automatic adjusting means for resetting the barrel to its desired direction after firing, said adjusting means including
- a source of radiation emitting a radiation beam, said source being provided radially offset relative to the direction of firing, the beam (.nu.) emitted by said source being directed to a mirror rigidly connected with the barrel and the beam (84 ') reflected by said mirror being detected by a position detector arranged in the direction of firing;
- and
- a servomechanism operatively connected to the barrel, said servomechanism receiving signal outputs (Y, Z) from an evaluation circuit means for computing and evaluating deviations of said barrel from said desired direction using output signals from the detector.
