Abstract

630,277. Axial-flow compressors. LOMBARD, A. A. Feb. 12, 1947, No. 4105. [Classes 110(i) and 110(iii)] The housing for the rotor bearing is supported by struts or webs extending across the compressor inlet in such manner that the aerodynamic disturbance due to a strut or web does not affect the whole length of a rotor blade at the same instant. The compressor may form part of a gas turbine plant. Struts 23 of aerofoil section extend between, and 'are preferably cast in one piece with, outer and inner rings 12, 15. The struts are non-radial to the compressor axis, and their inclination may be such that they lie substantially tangential to the outer radius of the inner ring 15. The struts may be hollow or otherwise provided with ducts 24 for the supply of lubricant or cooling air or accommodation of starter motor power-leads. The outer ring 12 is attached to the inlet end of the compressor casing 14, and has a recess 25 for the reception of the outer ends of guide blades 11 which are supported at their inner ends by the inner ring 15. A frustoconical member 18 extends inwardly from the inner ring 15 to support a rotor bearing 20. A nose cap 17 may house a starter motor and fuel and lubrication pumps. The struts may be directly connected to the compressor casing without the interposition of an outer ring, and they may be pivotally jointed at either or both their inner and outer ends.
