Abstract
A compressor construction is shown, in combination with a jet engine, having a drum rotor with axially broached attachment slots therein. Blade sticks, each having an axial root shaped to fit the attachment slots and a platform which extends the length of the drum are positioned on said drum. Each blade stick has a plurality of blades located thereon, one for each stage of the compressor. A one-piece stator case with fixed cantilevered vanes is positioned over said drum rotor and blade sticks to form the completed compressor. A drum rotor has an integral shaft which is connected to a turbine. A method of assembling the compressor includes an assembly fixture on which the drum rotor can be positioned with the stator case and blade sticks being aligned so that they can be slid into place on the drum rotor.
