Abstract

1,118,898. Turbine and compressor rotors; jet propulsion plant. ROLLS-ROYCE Ltd. April 3, 1967. No. 15224/67. Headings F1J and F1T. A fluid flow machine, such as a compressor or turbine of a gas turbine engine or a ducted fan driven thereby, has angularly spaced rotor blades 15 extending radially outwardly from a sleeve member 16, an inner sleeve 23 inter-meshing with the sleeve 16 to transmit drive therebetween and a hub member 25 mounted concentrically within the inner sleeve 23 and connected thereto by angularly spaced struts 24, the angular spacing between adjacent struts 24 being substantially greater than that between adjacent blades 15. In the case shown, the blades 15 from a front fan of a gas turbine jet propulsion engine and are shaped to effect substantially constant work from their roots to their tips on the air passing through the fan. The blades may be of epocy or other synthetic resin. The sleeve member 16 is formed of carboniferous, boron or glass fibres coated with synthetic resin or coated with a nickel-chromium alloy. The sleeve 16 has angularly spaced inserts 20 embedded therein having teeth 21 meshing with corresponding teeth 22 on the inner sleeve 23 to provide a driving connection between the sleeves. Except in the regions of the teeth, the sleeves are radially spaced apart to permit limited radial movement therebetween. The struts 24 connecting the inner sleeve 23 to the hub 25 are of aluminium and are shaped to do no work on the air flowing there past. The hub 25 is driven through a coupling 26 and shaft 27 from the engine turbine.
