Integrated Design of Environmentally-friendly Aerospace Systems
Research at the IDEAS Lab aims to bring a holistic approach that accounts for the system-level and life-cycle impact of greenhouse gas emissions in the design and operation of unconventional aircraft concepts. Revolutionary technologies, such as electrified propulsion and hydrogen combustion, open up a new and exciting design space with many challenges and uncertainties. At IDEAS Lab, we use physics-based modeling, probabilistic and statistical methods, and systems engineering principles to analyze, understand and design the complex system behavior of an aerospace vehicle. We leverage probabilistic design methods to reduce the uncertainty associated with novel concepts in early design phases. We build reduced order models to expedite the analysis and simulation of large-scale systems. These techniques allow us to perform sensitivity analysis, visualize tradeoffs, and explore a vast and uncharted design space under varying constraints at the early design stages.
Research topics include:
- Aerospace systems design, integration, optimization
- Sustainable aviation with a special focus on electrified and hydrogen-powered aircraft concepts
- Statistical and probabilistic design methods
- Surrogate modeling and machine learning
- Model-based systems engineering
Electrified Propulsion Architecture Sizing and Synthesis: E-PASS
Developed by Dr. Cinar, E-PASS is an energy-based aircraft sizing and synthesis tool in MATLAB. E-PASS enables conceptual design and performance evaluation of advanced aircraft concepts with any type of propulsion architecture (including non-electrified), and allows for rapid comparisons between diverse architectures and their operations. E-PASS is powered by parametric, physics-based electric powertrain models. It serves as a modular multi-disciplinary analysis and optimization framework for novel aircraft conceptual design. Since 2018, the E-PASS software has enabled multiple research projects funded by the government and industry, including NASA, AFRL, and Boeing.
Design Space Exploration and Optimization
Traditionally, important design decisions are made and locked in at early design stages where knowledge about the design is limited and the methods rely on historical data. This results in a point design that can only be locally optimized for a predetermined set of requirements. At IDEAS Lab, we leverage probabilistic design methods to predict the effects of random variability and mitigate uncertainties associated with novel concepts. We strategically and efficiently sample and perturb the design space of a complex system to predict the system response including the random variability effects. We utilize statistical methods to build computationally faster reduced order models. This approach enables the creation of a fast, dynamic, and interactive design space exploration and optimization environment. This way we can perform the simulation and evaluation of thousands of sized designs, optimized under varying requirements - all of this at the click of a button! This environment can be used to perform “what-if” analysis, visualize the sensitivities of design factors to the system-level responses, make informed decisions about the design, and more.
