The present variable airfoil assembly has a fixed airfoil member with a shallow recess in the top in which an adjustable airfoil member is seated snugly, when lowered, to present a convex top surface which merges smoothly with the top surface on the fixed airfoil member in front and behind. When the adjustable airfoil member is raised, the fixed airfoil member presents a top surface below it which is continuous for most of its extent to minimize air turbulence. Reinforcing ribs on the adjustable airfoil member extend down through longitudinal gaps in the...
