Kiowa Assessment of Performance with an OH-58 Bendix Power Turbine Governor

Abstract

The ADF's Bell 206B-l Kiowa helicopter fleet had incurred an increasing number of engine malfunctions attributable to the engine's aging CECO governor system. The installation of the Bendix system was investigated in late 1998 and an assessment by direct comparison was conducted in Aug 99. The Bendix system displayed superior characteristics, particularly at the extremes of the aircraft's maneuverability and altitude envelope and was incorporated into the fleet. Subsequently, some of the aircraft demonstrated non-repeatable N2 variations and Bell proposed fitment of the OH-58 PTG. Trial of the modified Bendix FCU successfully took place in Dec 00 which demonstrated no tendency towards N2 variations and displayed improved transient and static droop characteristics over the original Bendix FCU configuration.
