Engineering Flight Test AH-1G Helicopter (HueyCobra) Phase D. Part 3. Vibration Characteristics

Abstract

The Phase D, Part 3 Airworthiness and Qualification Aircraft Vibration Tests of the AH-1G Helicopter were conducted. Six vibration parameters were evaluated to determine model specification compliance and mission suitability information for inclusion in technical manuals and other publications. The vibration levels of the AH-1G met all requirements of the detail model specification; however, a reduction in the vibration levels at airspeeds from maximum level-flight airspeed (VH) to limit airspeed (VL) is desirable for improved mission suitability. The detail model specification did not require any specific vibration levels at airspeeds other than VH. Future detail model specifications should contain vibration limits for all flight conditions and aircraft configurations.
