Laser beam welding of aircraft fuselage panels
ICALEO 2002: 21st International Congress on Laser Materials Processing and Laser Microfabrication, 2002Today riveting is the standard process to join parts during the manufacturing of aircraft shells. Mainly, the Aluminium alloy AA2024 is applied for the skin of the fuselage. In 1987, the weldable alloy AA6013 was introduced to the market and at the beginning of the 1980s, powerful laser sources were realized.

Fuselage panel noise attenuation by piezoelectric switching control
Smart Materials and Structures, 2010This paper describes a problem that we encountered in our noise attenuation project and our solution for it. We intend to attenuate low-frequency noise that transmits through aircraft fuselage panels. Our method of noise attenuation is implemented with a piezoelectric semi-active system having a selective switch instead of an active energy-supply ...

Adhesive bonding of large fuselage panels
Aircraft Engineering and Aerospace Technology, 1972AS DEVELOPED, the TriStar body is a conventional semimonocoque shell construction with a constant cross‐section of 235in diameter along most of its length. Bonding is utilised throughout the 150ft of airframe pressurised zone to join doublers and triplers around openings in the skin. Skin and stringers are supported by sheet metal frames spaced at 20in
