Abstract
The Journal of Aerospace Technology and Management is a techno-scientific publication serialized, edited, and published by the Institute of Aeronautics and Space (Instituto de Aeronáutica e Espaço-IAE).
Highlights
There are many parameters that characterize a blowdown Supersonic Wind Tunnel (SWT) such as the test section dimensions, operating characteristics (Reynolds number x Mach number), general capabilities of the facility (Mach number range, maximum stagnation pressure) and so on
Comparison of the system response of the model simulation and the actual wind tunnel test (Fung, 1987) data was made to determine the applicability of the model
The following conclusions were drawn from the results of simulations: (a) Plant without Controller (i) The isentropic approach can be used for preliminary design of the control system based on stagnation pressure at the settling chamber or Reynolds number at the test section
Summary
