Abstract

523,196. Screw propellers. DE HAVILLAND AIRCRAFT CO., Ltd., THOMAS, F. M., and HITCH, F. A. N. Sept. 23, 1938, No. 27809. Drawings to Specification. [Class 114] [Also in Groups XXVI and XXIX] Internally meshing gear-wheel rotary engines having a compound epicyclic gear train are used as pitch-changing motors for variable-pitch air-screws. The motors may be arranged as servomotors.
