    Guest lecture: Efforts Toward Highly Coupled Multidisciplinary Design Optimization of Air Vehicles

    We are pleased to invite you to a guest lecture from a graduate of our aerospace program at the TU-Berlin, Dr Christopher Lupp. The lecture will take place at 10 am, on May 22nd.

    Title: Efforts Toward Highly Coupled Multidisciplinary Design Optimization of Air Vehicles

    Outline of the presentation:

    In aircraft conceptual design, a lack of analyses in early design stages (e.g. aeroelasticity, or power and thermal systems) may lead to an infeasible design once these disciplines are considered in later phases. These required design changes may be very expensive or result in lost vehicle capabilities. As a result, it is desirable to include these disciplines earlier in the design process with sufficient fidelity. The presentation will focus on gradient-based optimization and how aeroelastic constraints and power and thermal subsystems can be modelled earlier in design phases, emphasizing path-dependent problems (for example, the power and thermal problem is highly path dependent).

    The presenter intends to give a brief overview of how gradient-based optimization works. The past and ongoing research efforts to include nonlinear aeroelasticity in the optimization. The presenter will also show coupled vehicle and power and thermal subsystem sizing based on some past work that was done to calculate feedback controllers

    Presenters Bio:

    Dr Christopher Lupp is a Research Aerospace Engineer at the Air Force Research Laboratory (AFRL) in Dayton, Ohio, specializing in Multidisciplinary Design Optimization (MDO), co-design, and nonlinear aeroelasticity. Having grown up in Berlin, he received a Bachelor of Science from the Technische Universität Berlin in 2013. In 2014, he started graduate school at the University of Michigan and received a Master of Science in Engineering from the Department of Aerospace Engineering in 2018. After working on the NASA Passive Aeroelastic Tailoring project, the Airbus/University of Michigan Center for Aero-Servo-Elasticity of Very Flexible Aircraft (CASE-VFA), and the AFRL/University of Michigan Collaborative Center for Air Vehicle Design (CCAVD), he defended his PhD in May 2020 and joined AFRL.

    At AFRL, Dr Lupp has served as the AFRL program manager for the AFRL/Lockheed Martin Skunk Works EXPEDITE program while directing internal research on effectiveness-based design and gradient-based MDO. His research has centred on applying gradient-based optimization to highly-coupled vehicle design, including vehicle, subsystem, and feedback controller sizing.
