Lifting force and flow resistance measurement device for measuring such force and resistance in aerodynamic models has a moving base plate to support a vertical floor-mounted column with a lever

摘要

A fixed base plate supports a vertical column with a moving lever (3) on bearings on its top end. The end of a short lever arm (3a) links via a vertical bracket (23) to a bottom side lever (22) fitted to correspond to the lever arm. The end of a longer lever arm (3b) has an active link to a spring resistance gauge (5). An adjustable stoppable Tarrier weight (4) fits on the longer lever arm.
