Abstract

An aircraft propeller blade is constructed by producing two shells 307, 309 of fibre-reinforced epoxy resin laminates, placing one shell in a mould, positioning a titanium blade spar 318 within the mould by means of an aligning mechanism, positioning foam filler elements 324, 326 adjacent the spar, applying adhesive to the spar, foam elements and insides of both shells, positioning the other shell within the mould, enclosing the assembly within the mould, and heating to cure the resin and bond the components together. The blade is provided with adjustable balance weights (340, 342) (Fig 4) whereby the centroid of the blade may be adjusted in both the radial and chordwise directions. For balancing a plurality of blades in a bladed rotor, a method is disclosed whereby the positions of the centroids for each blade are measured, a standard position within the range of measured positions is selected and the positions of the centroids of all blades are then adjusted in accordance with the selected standard position. <IMAGE>
