Abstract

938,123. Blade shrouding. STUDEBAKERPACKARD CORPORATION. May 19, 1960, No. 17712/60. Class 110 (3). Shrouding for the tips of rotor blades 16 comprises an inner ring of channel-shaped blade receiving segments 18, and a second ring of channel-shaped segments 19 received within the flanges 21, 22 of the first ring and provided with a substantially continuous winding 36 of filamentary material forming a retaining band round the second ring. The segments 18 and 19 may be moulded from resin impregnated fibre glass cloth and are cemented together and to an intermediate cellular member 23 of perforated light weight material such as resin impregnated fibre glass or of perforated aluminium. The winding 36 may be of fibre glass rovings impregnated with a suitable resin. Alternatively all parts of the shroud may be made of metal, when the winding is formed from stainless steel wire, adjacent convolutions being locked together by solder. The tip of each blade 16 is slidably engaged in the slot 28 in a bushing 27 formed of hard stiff synthetic plastic and provided with an external groove which engages the edges of a slot 26 provided in each segment 18. Each bushing passes through the member 23 and engages the corresponding segment 19, and may be formed to an appropriate aerodynamic shape. In another embodiment, the shroud may be formed of a strip of synthetic plastics, around which is disposed a retaining band made up of a filamentary winding which may comprise glass fibres. The Specification also describes a method of forming this shroud.
