In order to study the intake characteristics of any air intake model in a wind tunnel, the mass flow through the intake duct needs to be simulated accurately. This can be done by a precise control of the mass flow plug at the downstream end of the intake model. In this work, an existing mass flow plug which is fixed to a DC motor is used and is moved axially at different positions in order to simulate the pressure ratios across the plug and thereby characterise the different engine parameters like total pressure recovery, total pressure distortion etc. This paper presents the development of a new NI LabVIEW based control system for the precise control of the mass flow plug during the testing of air intake model. This system can be used for continuous mode, step mode or preposition modes of mass flow plug operation. The control system is validated by conducting static tests of a typical air intake model at High Speed combustor test facility.
