ABSTRACT:
Workpiece loading, particularly for dynamic testing of aircraft wings, is described. A double ended servo jack is drivably coupled to an upper drive lever which is pivotally mounted for movement relative to the workpiece. The follower end of the upper drive lever is coupled by a tension strap to a lower drive lever. The drive ends of the upper and lower levers are coupled to contour boards provided around the wing by means of whiffle trees so that the single jack applied both upwards and downwards forces to the wing.
