CU Dials and gauges on equipment tell the reactions of various parts of the model, giving comparisons between the drag profile of the cone and hovercraft. CU A hand suspends a missile cone model in the tunnel with the use of magnets. CU Cone in tunnel. CU Dials recording model position and coil current. CU Hands holding models of hovercraft and missile cone. (3 shots). LS Wind tunnel and technicians at work. (3 shots).
Note: Date on original record: 16/02/1966. Contemporary notes record that the models were subjected to wind velocities of 6000 miles per hour (Mach 8.6). The power required to operate the magnets holding the models in position was 50 kilowatts. The model's temperature rose to 150 degrees Centigrade after 10 seconds' application of air at maximum velocity. This equipment was used to study the wake flow over models that had previously been impossible, thus ensuring far more accurate force measurements.
