Developments in testing airfoil techniques at University of SouthamptonThe evolution in Europe of the flexible walled test section, as applied to two dimensional testing at low and transonic speeds, is traced from its beginnings at NPL, London, in the early 1940's, and is shown to lead logically to the latest version now nearing completion at Southampton University. The principal changes that have taken place are improvements in the methods of choosing wall contours such that they rapidly follow appropriate streamlines, and reductions in the depth of test sections. The latest transonic test section presently under assembly at Southampton has, as its principal new feature, the facility for the automation of wall streamlining with the aid of an on-line computer. The versatility of the flexible walled test section is emphasized by reference to the simulation of alternative flows including cascade, steady pitching in an infinite flowfield, and ground effect. Finally, sources of error in streamlining are identified, with methods for their alleviation.
