Device for the alignment of an aiming axis body at a target position

A hydraulically operated rotational drive system, preferably for a Gatling cannon or gun, comprises a first hydraulic motor for the driving phase and sustenance of a predeterminate operating speed as well as for base load operation for the braking phase, and being continually operatively connectable to a second hydraulic auxiliary motor. During the start-up or run-up phase, until attaining the required speed, as well as during the braking or deceleration phase, this second hydraulic motor is operatively and/or controllably, automatically connectable to the first hydraulic motor for energy-saving operation. Operative and controllable connection of the first and second hydraulic motors is accomplished by means of an operative connection of the hydraulic system with the hydraulic motors on the one hand and with a pressure source and a tank on the other hand. This hydraulic system comprises several supply lines, return lines, control lines and bypass lines, as well as valves, which are controllable and/or switchable according to requirements.
