ABSTRACT:
An apparatus is disclosed for measuring force components exerted by a flowing medium such as air in a wind tunnel upon an object to be measured. The object is rigidly attached to an object carrier movable in a first direction in a first bearing guide member. A first measuring force device connects between the object carrier and the first bearing guide member to restrain movement of the object carrier in the first direction. A second bearing guide member in the first bearing guide member is movable in a plane perpendicular to the first direction with second and third measuring force devices being connected between the first and second bearing guide members to restrain movement of the object carrier in the plane. A third bearing guide member may also be provided on which the second bearing guide member is movable to permit a pivoting movement of the second bearing guide member. All of the bearing guide members are preferably constructed as hydrostatic bearings.
