ENGINEERING FLIGHT TEST OF THE AH-1G HELICOPTER (HUEYCOBRA). PHASE B. PART 1
Abstract
Part 1 of the AH-1G helicopter Phase B test was conducted at Ft Hood, Texas by the US Army Aviation Test Activity, Edwards AFB, California. The helicopter flying qualities were evaluated throughout the aircraft speed range for the Scout and Hog configurations at a mid-center-of-gravity location. Flying qualities were also evaluated during weapons firing and external stores jettison. The primary deficiencies detected during this test were stability and Control augmentation system (SCAS)-pylon coupling, inadequate in-ground-effect (IGE) directional control power, undue pilot attention required to avoid exceeding the torque limits of the helicopter transmission in dives and left rolls with fixed collective, and an inadequate, illogical fire control system. Other shortcomings were detected, such as airspeed system errors, degradation of flying qualities with SCAS off, static lateral cyclic control force imbalance, and marginal cockpit ventilation. Helicopter reactions to weapons firing and external stores jettison were satisfactory, and the contractor approved flight envelope for firing and jettison was acceptable.
