Vibration absorption in aircraft airframes in transonic flight

摘要

The aircraft which has a fixed wing (7) carrying an engine (M) has its transonic vibration absorbed or prevented by the addition of a fixed mass (12,13,14). This mass is distributed asymmetrically either side the fuselage. The total mass is housed inside one of the right or left wings or distributed in two unequal parts in one wing. The mass is placed inside the wing which vibrates the most. It is fixed on a part of the wing beyond the engine axis (M) and placed as near as possible to the wing tip and near the front longeron (8).
