Abstract
1291562 Moulding propeller blades HAWKER SIDDELEY DYNAMICS Ltd 16 Oct 1969 [22 Oct 1968] 50171/68 Heading B5A [Also in Division B7] In a method of manufacturing a propeller blade a longitudinal load-carrying spar 11 built up from synthetic resin material reinforced with longitudinally extending carbon fibres is disposed within a containing shell 12. In the embodiment shown two individual half-blades are separately moulded, without a blade shank or root portion, in a reinforced resin material further reinforced with longitudinally laid carbon fibres and are then bonded together. The blade shank and root are then formed by compressing the protruding ends 19 of the carbon whiskers from both halves of the blade between male and female moulds 20, 21.
