Abstract

A small secondary leading edge device, called a compound Krueger vane, works in parallel with a primary device (e.g., a Krueger flap) to delay flow separation on an aircraft wing. The compound Krueger vane is deployed behind a gapped Krueger flap to turn flow ahead of the wing attachment region on the underside of the wing. The compound Krueger vane turns flow that moves forward from the wing lower surface attachment region toward the leading edge of the wing, thereby delaying flow separation on the aircraft wing.
