A New Approach to the Delta Wing Problem
Department of Mathematics, University of Surrey Guildford, England
The "delta-wing problem" involves a solution of Laplace's equation near the apex of an infinite sector, subject to certain boundary conditions; it is known that the solution involves rv where r is the distance from the apex and v is a parameter depending on the angle of the sector. The core of the problem is the determination of v.
This paper gives a new approach, based on the use of elliptic conal coordinates, and the solution of the resulting Lamé equation by a new perturbation technique.
