The preliminary design of high-altitude, long-endurance RPVs is complicated by the paucity of data concerning airfoils with high lift coefficients at low Re numbers. Attention is presently given to a generic airfoil of this type for the design Re number range of 700,000 to 2 million. Low drag is predicted for lift coefficients from 0.4 (for high speed dashes) to 1.5 (for maximum mission endurance). The airfoil is such that its maximum lift coefficient, at 1.8, is unaffected by the surface contamination that would be encountered during takeoffs and landings in rain or over insect-infested runways.
