Choke – A vital component of the transonic wind tunnel is the variable choke. Positioned downstream of the test section, the choke works in concert with the stagnation pressure control valve, variable test section porosity and test section extension pressure flaps to achieve and maintain target airspeed.

Half-Model test has important meaning in the research of aerodynamic performance, high-lift system and flow control techniques of transport ... wind tunnel, a new half-model force balance BMTP2 for half-model test is designed. BMTP2 is a six-component box type balance, mounted
There's nothing to stop you building a super-giant wind tunnel and testing a life-sized model of your plane—and, indeed, the American space agency NASA does have wind tunnels like this. But most of the time it's much cheaper to use a small, scale model of the plane in a much smaller wind tunnel.
It is being tested in a wind tunnel at the Arnold Engineering Development Center in Tullahoma, Tenn. Put that wing in a wind tunnel and measure the effect of various wind speeds and you have a simulation. Before conversion work began at the Intracom plant at Smolensk, a scale model was tested in a wind tunnel at the Zhukovsky Institute in Moscow.
Wind Tunnel Test of a Canard Airplane Chung Jindeog*, Cho Tahwan Senior Engineer, Korea Aerospace Research Institute Lee J angyeon, Sung Bongzoo Principle Engineer, Korea Aerospace Research Institute, Taejon 305-600, Korea A low speed wind tunnel test was conducted for a canard airplane model in KARl LSWT.
The rule of thumb is that the frontal area of the model seen by the flow should be less than 7.5% of the cross-sectional area of the test section. So if you want to test a full size VAWT you will need a very large wind tunnel.
tunnel, tunnel with a simpliﬁed S60 and tunnel with a detailed S80. The results have been compared to ordinary CFD simulations and to newly made experiments in the wind tunnel. The ﬂow produced by the numerical simulations in the empty wind tunnel has proved to be largely asymmetric due to the asymmetric geometry oftheslottedwalls ...
