In the description we published of the machines engaged in this year's Deutsch de la Meurthe Cup race (“Modern French Racers,” by R. J, de Marolles, AIRCRAFT ENGINEERING, Vol. VI, July 1934, pp. 179–182) brief mention was made of the Ratier and Levasseur variable pitch air‐screws employed. The Ratier type was fitted to the winining Caudron, C.450, with a 320 h.p. Renault engine, and the Levasseur to the Caudron, C.366, with a 217 h.p. Régnier engine which finished second. We are enabled, through the courtesy of the editor of “L'Aéronautique,” to reproduce here, in this and the following article, descriptions of both these interesting types of variable pilch airscrew, based mainly on articles which appeared in the July issue of that journal. We are particularly indebted to M. Douche for the loan of the originals of the illustrations.
