Auslegung einer Passagierugzeugtür in Faserverbundbauweise

Abstract

The thesis deals with the dimensioning of a Pax-door of a single aisle aircraft like the Airbus A320. Especially the potential of composites and modern plastics will be used to gain an effcient lightweight design. A model of the fuselage from the EU project MAAXIMUS can be used for the basic dimensioning of the door. The loads and load cases, are derived from the european Certification Specifications for Large Aeroplanes (CS- 25). Basically a topology optimization of an isotropic solid material is used to generate a design adequate to the load paths. This design is developed further, for being feasible with composites. Failure criteria are evaluated to find weak spots in the design. A manual optimization of the layup will be done to build a design, which can resist the applied loads and load cases. As a result it can be determined, that a design could be found, which _ts to the specifications and gained a weight reduction about 8,15% to the common CFRP design.
