• The ULI funding enabled interactions among groups that usually do not closely interact, in this case, sensing, aerodynamics, design optimization and structural morphing. It was a challenge during Year 1 that took active intervention to make it happen and be functional during Year 2.
• It brought the university and industry communities together. This close collaboration is facilitating technology development, including development of a framework for low and high fidelity aerodynamic tools, rapid geometry optimization, identification of adverse boom conditions, improved boom propagation tools, and keeping the team on a path towards technology transition.
• While close industrial collaboration is effective, the academic institutions lead the effort. This is something that is unique to the ULI (by design). We were fortunate to get top talent from industry and they have been able to collaborate without taking over the effort.
• Student engagement has been extremely successful, especially undergraduate students, who perceive the ULI as a great opportunity to be involved with.
• Input from External Advisory Board has been important and very useful in revectoring scientific focus and improving collaborations.

Leadership
• The ULI program is about putting universities in-charge of technology development that can transition to industry use. This should continue.
• The ULI program should formalize industry participation and reflect this into the scoring of proposals.
• Industry needs to participate closely, but it has to take on a secondary role to the university’s leadership. This requires depth of engagement and collaboration between industry and universities that should be recognized and rewarded.
• The ULI program should formalize expected institutional commitment and support and reflect it into the scoring of proposals.
• The ULI should expect closer connections with NASA Centers, especially for student opportunities and integration of tools and focus on technology transitions for the outer years of the effort.

and atmospheric conditions on boom signatures.
• Improved understanding of the problem is the first step in finding
solutions that will allow a return to overland supersonic flight, a key
NASA goal.
• We are beginning to develop potential solutions and tools to ‘correct’
loud booms under adverse conditions.
