Demonstration of an Multidisciplinary Design Analysis and Optimization (MDAO) Process for Vertical Lift Vehicles challenge is to overcome the current practice of a serial design approach using single-discipline optimization, NASA will develop and demonstrate a streamlined, integrated, multi-disciplinary optimization process of consistent fidelity for conceptual design of Vertical Takeoff and Landing (VTOL) aircraft.More »
Enables the ability to use formal optimization tools to assess configuration trades for multiple requirements. Will provide cleaner , quieter VTOL configurations that serve as drivers for focusing and advancing technologies.More »

In closing out the MDAO process, an assessment of the environmental impact of a vehicle can now be made in a much more integrated approach.
The final tool chain demonstration goal supporting this Technical Challenge was to design a VTOL aircraft with at least 50% lower emission and 70-80% lower noise than the corresponding baseline vehicle. In 2016, the plan was to develop an acoustic module appropriate for conceptual design vehicle optimization – the module or surrogate was not developed by the completion of this Technical Challenge. Rather, acoustic optimization was completed using a high-fidelity analysis instead of a surrogate model. The analysis predicts that the low-emission, low-noise Side By Side vehicle design would produce 60% less emission and is 9.6 dB (67%) quieter than the baseline vehicle
