The test aircraft has been used in training for about 12,000 hours at the Civil Aviation College. The transfer function method with dual correlated random excitation was adopted in this test. The test results showed that several vibration modes were separated and that the resulting natural frequencies and nodal lines were similar to those of the original prototype aircraft. The vibration characteristics did not show any appreciable difference between the aged aircraft and the original prototype aircraft. It is also confirmed that the dynamic displacement measurement system operated effectively for full scale vibration tests., 資料番号: AA0001658000, レポート番号: NAL TM-732}, title = {経年航空機の全機地上振動試験}, year = {1998} }
