Abstract

1,150,123. Blades for rotary wing aircraft. WESTLAND AIRCRAFT Ltd. 11 Dec., 1967 [8 Feb., 1967], No. 6109/67. Heading B7W. A helicopter rotor blade 10 comprises a spar 11 which has root and tip portions 11a and 11b respectively of greater chord than the intermediate portion of the spar, the spar being of U-section. A shaped honeycomb core 12 is bonded inside the spar, and to spin plates 13, to complete the basic structure of the blade. The leading edges of plates 13 abut a protective nose capping 15 and the root portion is reinforced by external plates 20 formed with rotor head attachments 21. The nose portion of the blade carries a tube 16 for balance weights 17 and further balance weights may be located in tip portion 11b. Trim tabs 24 are provided.
