On the Design of Aerofoils for which the Lift is Independent of the Incidence

摘要

It has been shown in R. & M. 26111 how lift may be obtained on aerofoils independently of the incidence. In this paper mathematical processes are set out of designing such aerofoils to have specified velocity distributions at certain incidences and lift-coefficients. Approximate and exact methods are given, corresponding to the methods employed in the design of ordinary aerofoils. Several shapes are worked out, some of them being the product of ideas not given in R. & M. 26111. A full discussion of the characteristics of such aerofoils is given.
