Description1- x 3-Foot Supersonic Tunnel No. 1 (9413276711).jpg
This cut-away drawing shows a sting mount penetrating a model Lockheed P-80 Shooting Star with strain gauges inside the fuselage to measure aerodynamic forces. The two 1- x 3-foot supersonic tunnels at Ames were among the first built without external balances, thus relying solely on strain gauges for force and moment measurements.
