Abstract
1,122,616. Casting composite articles. AIRSCREW WEYROC Ltd. 21 April, 1967 [2 May, 1966], No. 19247/66. Heading B3F. [Also in Division F1] A metal fan impeller is constructed by first forming a number of blades 2 having root portions 3 and then casting the hub 4 over the root portions. The root portions have a circular cross-section at their base and an elliptical cross-section adjacent the hub periphery to prevent blade rotation. The hub may be a sand or gravity casting of aluminium alloy cast with a cast iron insert 5 for receiving the shaft. Alternatively, the insert may be bolted in the hub subsequent to casting. The blades are of aerofoil section and may be gravity die-cast or forged from aluminium alloy. The blades and hub may be of ferrous alloy.
