The aerodynamic configuration of a swept back aircraft wing for alleviating the wake-vortex hazard behind the aircraft is discussed. The airflow behind the wing is altered by deployment of segmented flaps to produce tailored span loading. Sawtooth span loading is used to generate a translating sheet of air flow energy which develops several unequal vortex pairs which break up the turbulent wake. Diagrams of the wing planforms and the resulting wake distribution are provided.
