Ground Vibration Tests on the Airbus A321 Aircraft Equipped with CFM56-5B Engines.

Kurzfassung

This report describes the ground vibration tests performed on the second prototype of the Airbus A321 aircraft equipped with CFM56-5B engines. The tests were carried out at the final assembly line in Hamburg during March, 1993. The investigations were performed on the aircraft with empty fuel tanks. Up to 50 Hz the normal mode parameters were measured including linearity checks. All test results are summarized in this report.
