摘要

Within the framework of a national technology programme under a contract awarded by the Netherlands Agency for Aerospace Programmes (NlVR), a composite stabilizer was developed by Fokker Aircraft B.V. in close collaboration with NLR. One of the activities in this technology program for NLR was to develop a test box for testing large composite skin panels and to test the composite panels on this box. The main goals of this part of the program were: -- To develop a single test box on which a number of test panels with different configurations could be loaded to relatively high strain levels without incurring damage to the test box; -- To load the test panels in such a way that an optimum correspondence between strain distributions in the test panels and the horizontal stabilizer skins was attained, -- To validate the design concepts of the skin panels by comparison of calculated and measured strain distributions. All objectives have been met successfully. -- Sir different panels were tested on a single metal test box. The panels were loaded up to a maximum of 3.0 times Limit Load with a total of 2l different loading conditions without incurring any damage to the metal test box. -- The loading of the test panels was such that an acceptable correspondence of the measured strain distributions and the calculated strain distributions in the horizontal stabilizer skins was attained. -- The measured strain distributions compared quite well with the calculated strain distributions for the test panels.
