Stock image of a television camera being focused by NACA technician on a ramjet engine model through the schlieren optical windows of the 10 x 10 Foot Supersonic Wind Tunnel’s test section. Closed-circuit television enables aeronautical research scientists to view the ramjet, used for propelling missiles, while the wind tunnel is operating at speeds from 1500 to 2500 mph.
