Abstract

This report presents a method for measuring the mass-flow rate in a rectangular13; duct fixed downstream of a supersonic air-intake model using a rake with 25 total13; pressure probes and 14 wall static pressure taps using a PC based program . The13; method has been used for obtaining the mass-flow rate through the intake of a13; typical ram jet air-intake model at supersonic Mach numbers in the NAL 0 .3m13; wind tunnel . The uncertainty in measurement of mass-flow rate is about xB1; 5%
