Velocity Distribution on Untapered Sheared and Swept-back Wings of Small Thickness and Finite Aspect Ratio at Zero Incidence

摘要

This report is a continuation of an earlier one1 and puts forward several new solutions of the problems of velocity distribution on finite or semi-infinite untapered wings, at zero incidence. The solutions are based on the first order method of sources and sinks, which is shown to be sufficiently accurate to deal with problems involving tips or kinks. The fundamental case considered is that of a semi-infinite sheared wing, and the theory is built up to embrace finite sheared and swept-back wings, straight wings being dealt with as special cases. Complete detailed solutions are given for wings with biconvex parabolic profile, and the problems involving arbitrary profiles are investigated in a more general way.
