Acoustically attenuated fuselage for aircraft |
摘要 |
A covering of a fuselage for aircraft having propeller engines, including an opening which is surrounded by a structural frame formed by ribs and stringers of the aircraft around the area of maximum acoustic impact of the propeller engines. The opening further includes a non-structural panel joined to the structural frame by a non-rigid joint which considerably attenuates the vibrations through such joint, thus reducing the indirect acoustic noise and the indirect structural noise generated by the propeller engines inside the passenger cabin of the aircraft.
