Aerospace Hybrid Lightweight Metallic Structures. Case Study - Design of a Turboprop Engine Support

摘要

Lightweight design is a major requirement of the aerospace structures. Aircraft welded structures are subjected to a complex system of certification requirements along with minimum weight target. Using hybrid technology structures, one may lead to better under load behaviour than using only welded structures. In this way, the design effort can be shorter even it employs more qualified resources. This article presents a case study of conceptual design of a turboprop engine support employing a milled part, too. A working method, the results, the design recommendations and the conclusions are presented.
