An Experimental Study of Three-dimensional High-Speed Air Conditions in a Cascade of Axial-flow Compressor Blades

摘要

Detailed investigations have been made by optical and physical methods in a high-speed wind tunnel of the flow characteristics of two compressor blade cascades.nIn Part 1 a representative high-camber cascade was examined at zero incidence over entry air velocities ranging from low to. critical. Traverses were made of discharge angles and wake losses at all heights so that a relation between two and three-dimensional losses could be obtained. Some records were also made of the nature of the vortices induced in the discharge flow.
