Lift and Drag
The balance assembly is an articulated parallelogram, linked to a load cell. The parallelogram resists bending moments so that only the force (not the moment) on the model is transmitted to the load cell.
The balance assembly is mounted on a carrier that runs along the rails of the FC300 Flume.
The display unit displays the force measured by the load cell. This unit is hung on the flume.
It can be interfaced to a PC by means of the flow channel Versatile Data Acquisition System (VDAS-FC). VDAS® allows force measurements to be captured, graphed and exported to a spreadsheet package for further processing.
