摘要： The present invention relates generally to a turbine engine (10) comprising a housing (12) in which a rotor (14) is rotatably mounted. The housing (12) of the turbine engine (10) is of a split casing construction including a center casing (24) sandwiched between a pair of outer casings, namely an inlet outer casing (26) and an outlet outer casing (28). The rotor 14 is shaped circular in profile and includes three working surfaces generally defined by a peripheral surface (32) and a pair of opposing sides surfaces (34) and (36), respectively. The peripheral surface (32) of the rotor (14) which acts as a fist stage of the turbine (10) includes a plurality of circumferentially spaced and generally axially directed ribs in the form of a series of arcuate flutes such as (38). The rotor (14) also includes a plurality of angularly spaced and radially extending rotor blades such as (40) which in transverse cross-section are aerofoil shaped with at least a portion of the concave or generally flat and convex surfaces of each of the blades (40) defining two further working surfaces of the rotor (14).
