The use of wind tunnels and scaled models to help solve the aerodynamics problems of aircraft as they are developed is a well-established method in the aerospace sector. Nowadays, with the tube and wing design of aircraft dominant in the market, they are more likely to be used for verification and certification.
Q. What is wind tunnel testing for aircraft?
Wind tunnel is an aerodynamic test facility. It is mostly used to study flow patterns around bodies and measure aerodynamic forces on them. The bodies (called models) are usually scaled down but geometrically similar versions of bodies of interest like an airplane or an automobile.

Q. What are the disadvantages of wind tunnel testing?
Disadvantages of the Open Return Tunnel
- Poor flow quality possible in the test section. Flow turning the corner into the bellmouth may require extensive screens or flow straighteners.
- High operating costs. The fan must continually accelerate flow through the tunnel.
- Noisy operation.
Q. Is CFD or wind tunnel better?
CFD analysis can give more insight in the design process. The method allows sampling at a high resolution and “mapping” of results in a highly visual and informative way. While CFD also resolves this turbulence, it is done so in an abstract way, whereas wind tunnels will resolve unsteady gusts and eddies directly.
Q. Will CFD replace wind tunnels?
To many observers the rivalry between wind tunnels and Computational Fluid Dynamics (CFD) is a zero-sum game – as CFD matures it simply replaces wind tunnels. However, this is far from the truth.
Q. How old was Kagome when she had Moroha?
Another thing to take into consideration. Kagome is born in 1982. In the original series, she’s 14-15 which means that the modern era it takes place around 1996-1997 (the year the Inuyasha Manga was released), she would be 18 in the three-year time skip which would be around 2000.
