INVESTIGATION OF A HIGH-PRESSURE-RATIO EIGHT-STAGE AXIAL-FLOW RESEARCH COMPRESSOR WITH TWC TRANSONIC INLET STAGESⅡ- PRELIMINARY ANALYSIS OF OVER-ALL PERFORMANCE

摘要

An investigation of the over-all performance of a 20-inch-tipdiameter, eight-stage axial-flow compressor was conducted as the initial step in an investigation of the problems encountered in a high-pressure ratio axial-flow compressor with transonic inlet stages. The compressor was designed to obtain a total-pressure ratio of 10.26 (a root-mean total-pressure ratio per stage of 1.338) with an equivalent weight flow of 65.0 pounds per second (a specific weight flow of 29.8 (lb/sec)/sq ft of frontal area) at an equivalent tip speed of 1168 feet per second.
