Airfield Erosion Control for C-5A Aircraft Operations.
Abstract
A study was conducted to map the surface velocity contours of the air movement and engine exhaust produced by the C-5A aircraft during takeoff roll and rotation. This study was undertaken to determine possible causes of runway shoulder erosion. Windsleeves and smoke grenades were to determine the directional nature of the surface air movement and engine exhaust. These data were then used to determine placement of Pitot probes to measure air velocity forces. Pitot probes and static pressure gages, containing strain-type electronic sensors, were placed along two parallel lines extending from 50 to 150 ft perpendicular to the centerline of the aircraft roll path. The entire takeoff roll was studied by conducting repeated test runs in which the aircraft breakaway point was progressively moved closer, in 1000-ft increments, to the instrumentation.
