The Langley Field Conference: An Account of the Principal Experiments Shown at the Annual Reception of the N.A.C.A.

THE National Advisory Committee for Aeronautics received this year so many requests for attendance at its Langley Field Conference that the visitors were divided into two groups and two demonstrations were given with a day intervening. It is a sign of general prosperity in American aviation that so many representatives of the industry, the universities and government departments were able to attend. Besides presenting in outline the results of much solid research work, the Committee was able to show two new and original pieces of research equipment, in the form of a free‐flight tunnel and a gust investigation tunnel. So much material was (as usual) presented to the visitors that considerations of space will only allow the most concise presentation in the present article.
