Turning Vanes inside the Altitude Wind Tunnel

In this February 1944 publicity photo, men stand in front of turning vanes inside the Altitude Wind Tunnel (AWT) at the National Advisory Committee for Aeronautics Aircraft Engine Research Laboratory. The AWT was the only wind tunnel capable of testing full-size aircraft engines in simulated altitude conditions. A large wooden drive fan, located on the other side of these vanes, created wind speeds up to 500 miles per hour.

小森林

每个人都有属于自己的一片森林,也许我们从来不曾走过,但它一直在那里,总会在那里。迷失的人迷失了,相逢的人会再相逢。愿这里,成为属于你的小森林。
