Tunnel Tests on High‐Speed Seaplanes: The Summarised Results of the N. P. L. Researches on the British 1927 Schneider Trophy Machines Available to Purchase

IN the early part of 1926, tests were carried out in the N. P. L. wind tunnels upon models of high‐speed seaplanes for the Schneider Trophy‐Competition in America. Owing to lack of time it was decided not to enter British machines for that contest, but the wind tunnel work was continued, as the Air Ministry wished to further the development of high‐speed craft. After the 1926 contest the Air Ministry decided to allow R.A.F. seaplanes to be entered by the Royal Aero Club, and to assist the Club in the competition in the following year. The high‐speed seaplane work was, therefore, again applied to machines for the Schneider Trophy Contest.
