Flight Evaluation Compliance Test Techniques for Army Hot Day Hover Criteria

Abstract

The effort consisted of determining the procedures for vertical climb and yaw maneuverability tests and recommendeding the compliance test procedure. The flight testing was primarily conducted with an AH-1G helicopter at Edwards Air Force Base and the Naval Weapons Center at China Lake, California from November 1970 through September 1971. The test results show that both vertical climb testing and yaw maneuverability testing involve limiting factors which result in uncertainty in the data. A test procedure was developed to demonstrate the yaw maneuverability and calculate the vertical climb capability, utilizing tethered hover test techniques to reduce the data uncertainty. This recommend procedure provided results which were in good agreement with the flight test results and should be adequate for determination of the hot day hover performance margin.
