Redesign of the Low Speed Three Stage Axial Flow Compressor Test Facility.

摘要

A flow configuration of an existing low-speed,axial flow compressor test facility at the Turbopropulsion Laboratory,Naval Postgarduate School,Monterey,California,was redesigned in order to improve compressor inlet velocity distribution,improve mass flow measurement,and increase the power input. The design of the new configuration,consisting of an inlet nozzle,ducting,throttling device upstream of the compressor,and a diffusor downstream of it,is reported. The redesign is based on using the existing free-vortex type and solid-body type bladings,and the newly designed symmetrical blading. (Author)
