Abstract

1437236 Turbomachine blades KOMBINAT LUFT-UND KALTETECHNIK VEB 11 Oct 1973 [12 Oct 1972] 47509/73 Heading F1T A blade for an axial-flow fan, compressor or supercharger is formed from a hard foam core I having incisions 2, 2', a slot 3 and a hole 3' where extra reinforcement is required, and enveloped in a reinforcing web of fabric 11, and is then placed in a mould into which a resin is allowed to flow to completely impregnate the fabric web. As shown, a web 11 is wrapped to cover the convex side of the blade continuously and passed through slots 2, 2' to the concave side. Reinforcing webs 12, 12' are then passed through the slot 3 and hole 3'. As further web 4 is then wrapped around the core to cover the concave side continuously and flaps 5 to 10 folded over the core edges to overlap and cover completely the convex face of the blade.
