The Handley Page Wind‐Tunnel: A Private Tunnel of the Closed‐Jet Type with a Single Return Duct Available to Purchase

THE first Handley Page wind tunnel was erected in 1916 and up to 1936 had produced a considerable quantity of data, a great deal of which was of a fundamental character, but, owing to the increasing performance of aircraft, its deficiencies were being felt, especially for the testing of complete models, although by employing partial models it was still of great use for tests on control surfaces.
