Span Loading and Wake Formation,

Abstract

Contrary to the classical assumption of an elliptic span loading, the actual span loading contains a logarithmic term. In consequence, there is an infinite upwash directly behind the wing just inside the wing tip. This explains why the aircraft wake rolls up faster than classical analyses predict. The downwash distribution behind the circular wing is calculated in some detail. (Author)
