​INFLOOR FORCE BALANCE

This force balance fixture was designed to measure lift and drag on a test object that is fixed onto the top plate. It's primary purpose is to allow for testing the influence of other objects on the same floor plane in close proximity. This force balance utilizes two 3-axis load cells, each attached to its own frame half. The two frame halves are joined by 3 structural members and a top plate. This allows for the fixture to be reconfigured, either lengthening or shorting the fixture, by replacing the 3 structural members and the top plate. Furthermore, this balance has been designed for quick installation, requiring no modification to the wind tunnels floor prior to installation.
