Abstract

910,185. Rotary wing aircraft. SHAPIRO, J. S., MEADS, B. A. G., and PRESTON, R. L. Oct. 22, 1959 [July 22, 1958], No. 23461/58. Class 4. A coaxial contra-rotating aircraft lifting rotor assembly comprises two coaxial rotor drive shafts, Oi, O 2 , driven by two independent engines, the axes of whose output shafts Ii, I 2 , enclose an acute angle in a plane perpendicular to the common axis of shafts O 1 , O 2 and meet on the common axis, each output shaft carrying a pinion P 1 , P 2 , meshing with two opposed crown wheels C 1 , C 2 , one on each of shafts Oi, O 2 . A third pinion P 3 relieving bending stresses on the crown wheels may be idle, or be connected to drive auxiliaries, or to a brake drum. The gear casing is in two parts H 1 , H 2 , between which is secured a rigid diaphragm D affording bearings for the ends of shafts Ii, I 2 , and for the inner end of the pinion P 3 , which has a bearing for its outer end in the casing.
