TECH ZONE
TECH ZONE is an additional area of our newsletter where each month an ARC's customer question will be answered by the relative expert at ARC. So, please send in any questions you might from, from wind tunnel test instrumentation, cfd workings to tuning your shocks.
Ask your questions at techzone@arcindy.com
How do you measure forces in the wind tunnel?
The model is mounted in the tunnel with a sting. Mounted inside the model is a 6 component balance that measures: Drag, Lift, Sideforce, Rolling Moment, Pitching Moment, Yawing Moment
In addition to the main balance, in truck testing a secondary six component balance measures all forces in the tractor unit. This helps the aerodynamicists when they are developing new aerodynamic parts to understand where the drag is being generated.
Finally the main balance is held within a model motion system that allows the tunnel operator to drive the model to different yaw angles, ride heights and pitch and roll, all whilst the moving belt is spinning at 110mph.
