AH-1G Helicopter Main Rotor Flow Survey.

Abstract

The Army requirement to fire unguided missiles from attack helicopters in hover and low-speed flight conditions has generated a need to accurately predict the rotor flow environment through which the missile must travel. Representative flight test airflow data is presented with which to determine the launch behavior of missiles and assess the accuracy of theoretical flow field prediction models. A UH-1M helicopter was previously used to develop instrumentation and test methodology for conducting the airflow survey which were applied to the AH-1G test program. The general test objective was to define the rotor wake boundary and three-dimensional airflow velocity components as a function of forward speed.
