A subsonic compressor designea to operate at high Mach numbers was tested, the measured pressure ratio being 1.38 at 22 lb/sec/sq ft flow and about 89 per cent efficiency. This efficiency was maintained at 5 per cent ...
The object of this investigation was the design of a supersonic wind tunnel for use in determining the internal flow in engine intakes between Mach 1.5 and Mach 3 and in ranges of pitch (+ 15 deg) and engine mass flow ...
