Development of a multifunctional fuselage demonstrator

This paper discusses the development and underlying requirements of a multifunctional lower fuselage demonstrator for a new single aisle aircraft undertaken as part of the Clean Sky 2, Large Passenger Aircraft – Platform 2. The demonstrator will validate high potential combinations of airframe structures, systems, cargo and cabin technology...

Mechanical and vibro-acoustic aspects of composite sandwich cylinders

Designing a fuselage involves many considerations such as strength and stability, fatigue, damage tolerance, fire and lightning resistance, thermal and acoustic insulation, production, inspection, maintenance and repair. In the background of the application of composite sandwich structures on the aircraft fuselage, the focus of the thesis is to...

Sound Transmission Loss Prediction of the Composite Fuselage with Different Methods

Increase of sound transmission loss(TL) of the fuselage is vital to build a comfortable cabin environment. In this paper, to find a convenient and accurate means for predicting the fuselage TL, the fuselage is modeled as a composite cylinder, and its TL is predicted with the analytical, the statistic energy analysis (SEA) and the hybrid FE&SEA...

Parametric fuselage design: Integration of mechanics and acoustic & thermal insulation

Designing a fuselage is a very complex process, which involves many different aspects like strength and stability, fatigue, damage tolerance, fire resistance, thermal and acoustic insulation but also inspection, maintenance, production and repair aspects. It is difficult to include all design aspects from the start of the design process. In this...
