Weight Estimation of Gas Turbine Engines: Development of a Component-Based Preliminary Engine Design Tool

The need for more efficient aircraft has spawned the conception of a variety of novel engine and aircraft architectures, such as the combined-cycle engine proposed by researchers at Delft University of Technology. To evaluate the potential benefits of these concepts comprehensively, in-depth performance simulations are required. Furthermore,...

Design Guidelines for Gust Load Inclusion in Aeroelastic Optimization of a Civil Aircraft in the Preliminary Design Phase

Fundamental phase in the preliminary design of an aircraft is the load case choice. Historically, the manoeuvres have been considered as the principal critical loads, while in conceptual design the gusts have been not investigated since, being an intrinsically dynamic phenomenon, they are expensive to analyze. Nevertheless, they are a critical...

Towards the Industrialization of MDAO: Evolving 1st Generation MDAO to an Industry Ready Level of Maturity

Multidisciplinary Design Analysis and Optimization (MDAO) promises major advances in aircraft design. However, judging from todays aircraft, MDAO is clearly not fully embraced by the industry yet. This is due to technical difficulties (coupling incompatible tools) and non-technical barriers (intellectual property).<br/><br/>Recent research, such...
