AEDC contributions to Viking ensures Mars first landing
The NASA Viking Mars Probe is set up here in 1971 for a free flight test at the AEDC von Kármán Gas Dynamics Facility by drilling a hole through the diameter of the two-inch models and suspending them on a wire. A system of pulleys and weights held the wire taut while the desired conditions were established inside the wind tunnel. Sudden force applied to the ends of the wire caused it to break within the model, leaving the model unsupported for a brief interval. This permitted engineers to examine the airflow, not only around the model, but also in its wake. Airflow is from left to right. Observing the test arrangement is then F.L. Badman, a test engineer.
