Selection criteria of optimal conditions for supersonic tests in a blowdown wind tunnel [PDF]
Scientific Technical Review, 2016 A natural desire of a wind tunnel test engineer is to plan and perform a test that will resemble the actual flight conditions as closely as possible. Geometric similarity and identical flight and wind tunnel Mach numbers are the primary requirements and ...

OPTIMIZED CONTROLLER DESIGN FOR A BLOWDOWN SUPERSONIC WIND TUNNEL BY USING GENETIC ALGORITHM [PDF]
مجله مدل سازی در مهندسی, 2017 Blowdown Supersonic Wind Tunnels (SWTs) are generally operated with a constant stagnation pressure in the settling chamber, with control usually provided by one or more pressure regulators or control valves. In this paper, first, a Simulink block diagram

Testing of calibration models in order to certify the overall reliability of the trisonic blowdown wind tunnel of VTI [PDF]
FME Transactions, 2010 It is strongly recommended that wind tunnel calibrations become a regular part of the operational cycle for any wind tunnel. They facilitate tunnel-totunnel data comparisons. Standard calibration model, representing a generic winged missile configuration,
