FLIGHT CONTROL SYSTEM LOADING TEST APPARATUS AND METHOD

摘要

A flight control system loading test apparatus includes a surface-mounted sector, a cam profile sector, a dummy weight, and a cable. The surface-mounted sector attaches to an aircraft flight control system body such that the surface-mounted sector pivots along with the body about a pivot axis. The cam profile sector is configured to rotate about a rotational axis among a plurality of loading positions. The cam profile sector includes a profile surface having a plurality of curves. Each curve follows a different radius emanating from a respective axis substantially parallel to the rotational axis of the cam profile sector. The cable contacts the cam profile sector along the profile surface. An applied hinge moment using the dummy weight varies as the cam profile sector rotates about the rotational axis.

1. A flight control system loading test apparatus comprising:
a surface-mounted sector for attaching to a flight control system body of an aircraft such that the surface-mounted sector pivots along with the flight control system body about a pivot axis as the flight control system body pivots about the pivot axis among a plurality of flight control system angles; a cam profile sector operatively connected to the surface-mounted sector and configured to rotate about a rotational axis among a plurality of loading positions as the flight control system body pivots among the plurality of flight control system angles, the cam profile sector having a profile surface including a plurality of successive curves, each curve following a different radius emanating from a respective axis substantially parallel to the rotational axis; and a cable connected with the cam profile sector and a dummy weight, the cable configured to contact the cam profile sector along the profile surface such that a hinge moment applied to the flight control system body using the dummy weight varies among the plurality of loading positions to approximate a pre-calculated actual hinge moment associated with the flight control system at each of the flight control system angles.
