Abstract:

The results of a design study to define a hydrofluidic armament control system mechanization for a helicopter gun turret are presented. The physical charactersitics and technical data for the XM28 Armament Subsystem were used to establish the requirements for this study. The design and analysis of a simple two-axis positional control system shows that the system is theoretically capable of a 5 to 10 mil accuracy. Two control mechanizations were considered, one in which all of the control components are fluidic and a second in which all components are fluidic with the exception of the position feedback loop, which is electronic. A system error analysis, based on present component state of the art, indicated that the combination fluidic electrical mechanization could presently provide the required system performance, while the completely fluidic mechanization would require component performance improvement in the areas of fluidic rotary position sensors and electric-to-fluidic transducers.
