Engineering Flight Test AH-1G Helicopter (Hueycobra). Phase D (airworthiness and Flight Characteristics). Part 2. Performance.

Abstract

Within the scope of this test, the AH-1G helicopter is suitable for the armed helicopter mission provided the insufficient directional control power and inadequate tail rotor drive system torque limitations are corrected. A directional control margin of 10 percent while hovering is the minimum acceptable for normal operation. Installation of the engine inlet screens and the engine particle separator decrease the performance capability of the AH-1G when maximum power available is the limiting parameter. The level-flight performance capabilities of the AH-1G vary with longitudinal cg location and improve as the cg moves aft. The degradation of hover performance capability when hovering in adverse crosswind is significant. The excellent climb performance, particularly from SL to 10,000 feet, enhances the capability of the AH-1G for the attack helicopter mission.
