Initial situation

Cabin monuments and large modules are of crucial importance for the realization of climate-friendly aviation. Individual customer requirements induce a high variance in cabin design. This leads to an oversizing of the interfaces of cabin modules and correspondingly to an increased total weight. In addition, individualization in cabin design leads to longer development times and increased costs in product development.

Objective

The aim of the subproject being worked on by PKT is to reduce development time by increasing the degree of modularity. For this purpose, methods are being researched that make it possible to reduce the time required for design and planning activities in product development. This should accelerate the introduction of new technologies and improve the flexibility of companies with regard to individual customer requirements. In addition, as part of a multi-model optimization (MMO) for the design of large module interfaces, various cabin variants will be considered that enable a modular cabin design with low overall weight.

Procedure

The existing interface development concepts are first subjected to a qualitative evaluation with regard to variant suitability and lightweight design potential and form the basis for the development of a modular interface concept for large cabin modules. Based on this, methodological support for holistic large-cabin module development in terms of modular lightweight design is developed and the integrated PKT approach for developing modular product families is extended. The link with existing methodological tools is made within the framework of a model-based approach using the SysML modeling language. This enables efficient and consistent method modeling.
For weight reduction of standardized platforms and large modules, an MMO is performed for different cabin and loading system configurations. In this way, an attachment solution can be identified that takes into account both modularity and lightweight requirements. For this purpose, existing solutions are analyzed and, on this basis, simulation and optimization models for large cabin module intersections are built. Weight-optimized design concepts can be derived from the optimization results. On this basis, a methodical procedure for MMO for interfaces for large module configurations will be developed.
