Abstract

1,082,352. Aerofoil construction. PARSONS CORPORATION. Oct. 2, 1964, No. 40251/64. Heading B7W. In an aerofoil construction, e.g. for a helicopter rotor blade, in which a spar 10 having a web 12 and margins 17, 18 extending aft of the web is attached to an aft structure comprising a structural skin 21, 22 with inwardly turned flanges 35, 36, and filler material 23, e.g. honeycomb, with an opening 30 forming projections 31, 32, the opening is lined with a structural skin liner 40 having flanges 41, 42 by which it is secured to the flanges 35, 36 and hence to the spar. The liner 40 is intended to prevent the forward edges of the projections 31, 32 detaching from the flanges 35, 36.
