Wind Tunnel Development Timeline
Wind tunnels have been used for studying the elements of flight since 1871. Initially, they were small-scale, open-loop devices such as the Wright Brothers’ tunnel with its 16-inch test section. Wind tunnels grew in size and complexity, particularly after the Ludwig Prandtl first closed-loop tunnel in 1909. Tunnels were built in a variety of sizes and shapes with varying speeds depending on the current technology and their intended areas of study. The AWT was the first wind tunnel built to study engine performance in altitude conditions. A list of important wind tunnels is below.

Vacuum Chamber Development Timeline
The first sustained vacuum was achieved in 1643, and the first vacuum pump followed in 1650. As humans began flying aircraft in the early 1900s, engineers began testing engines in vacuum chambers to simulate conditions at higher altitudes. As the nation began sending spacecraft into space decades later, there was a need for test chambers capable of producing higher levels of vacuum. The SPC was among the first of a wave of large vacuum chambers that emerged in the early 1960s. The Space Power Facility (SPF) at NASA’s Plum Brook Station, which began operation in 1969, is the largest vacuum chamber in the world. A list of vacuum chambers used to simulate altitude is below.
