The Mach number control analysis of the blowdown wind tunnel in the transonic velocity regime
Borivoj Blizanac The Mach number control analysis in the transonic velocity regime gives the equations for constructing programs that can iteratively solve the system steady-state conditions. The programs developed will be used to construct calibration curves for the feedforward control of the test section Mach number. The blow-off and ejector systems of the blowdown wind tunnel make hardware of the Mach number control system. The air flow process in both of these systems is analysed using the one-dimensional compressible flow theory. Ključne reči: Blow-off system, ejector system, Mach number. |
