Internal Balance
Design, manufacture, calibration and servicing of internal balances
Our Hybrid Force Balance has the advantages of both the single piece moment balance and the multi-piece force balance; balance designs are tailored to requested load capacity and geometry. The Hybrid Force Balance directly measures two forces (one forward and one aft of the Balance Moment Center) in the normal force and side force planes and measures rolling moment and axial force. Pitching moment and yawing moment are resolved from the forces and known distances to the Balance Moment Center (BMC). This design has reduced deflections and higher frequency response than a moment balance while maintaining a high level of accuracy.
Accuracy and Rigidity
Balance meets future testing needs - providing accurate model loads data under high loading conditions while allowing the model to maintain its shape at the sting exit.
Failsafe Configuration
If an unplanned wind tunnel event occurs, Calspan's internal balances are designed to capture the metric side of the balance and prevent/minimize tunnel damage.
