IRES Track 1: Advancing materials and combustion technologies for next generation propulsion and power generation systems at the German Aerospace Center (DLR)

世界范围内满足下一代高超声速亚轨道和可重复使用空间飞行器推进能力的努力依赖于跨学科和转型技术。该IRES为先进材料和燃烧领域的突破性新研究提供了重点机会，最终为美国研究生和本科生提供为期3年，每年在德国航空航天中心（DLR）为期2个月的体验。此次合作提供了利用DLR的大型独特设备（包括最先进的高温涂层沉积系统和高压激波管）进行制造和测试的经验。学生将深入了解燃烧过程中不同的物理机制如何影响材料的相互依赖关系，以及如何将其与整体发动机系统性能相结合。与阿贡国家实验室的独特合作伙伴关系为联合同步加速器实验奠定了基础，确保了德国和美国科学家在重大科学影响和优秀指导方面的双向交流经验。该项目在创造下一代能源、推进和运输技术方面具有深远的社会效益。国际研究的教育广泛影响是通过以下方式实现的：1)为不同群体的学生提供机会，在世界知名科学家和同行的指导下，在高度先进的设施中体验合作研究；2)培训下一代跨学科的全球科学家，以支持先进的燃气轮机和高超音速项目；3)通过与当地高中和初中学生的活动进行推广。互动博客和播客，以及通过一项新的互动Skype会议，将德国科学家与美国教室联系起来。通过德国航空航天中心（DLR）和中佛罗里达大学（UCF）之间的合作研究，该IRES项目为美国学生提供了国际经验，以扩展前缘、涡轮和燃烧室部件的材料系统的耐久性和高温能力，并阐明杂质和稀释剂对新燃料燃烧性能的影响。与此同时，这种定向的努力也可以扩大发电面积，消除氮氧化物的途径，对抗二氧化碳排放，并通过封存提高效率。这些领域的变革性技术的进步可以通过专门的跨学科研究来满足：1)新的燃烧策略，包括特殊的燃料反应；Ii)设计和表征能够承受高温和超高温且具有完整性和耐久性的材料；iii)利用增材制造来支持材料和燃烧需求的热管理策略。研究结果有助于改进优化燃烧性能的设计，这需要可靠的材料系统来实现推进和能源方面的先进技术。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

Worldwide efforts to meet next generation propulsion capabilities for hypersonic suborbital and reusable space vehicles rely on interdisciplinary and transformational technologies. This IRES provides focused opportunities of new and disruptive research in advanced materials and combustion that culminate in a 2-month experience for U.S. students, both at the graduate and undergraduate levels, every year for 3 years at the German Aerospace Center (DLR). The collaboration offers experiences in manufacturing and testing using large-scale unique facilities at DLR including a state-of-the-art high-temperature coating deposition system and high-pressure shock tube. Students gain an insight to how interdependencies operate where different physical mechanisms in combustion affect materials and how this integrates with the overall engine system performance. A unique partnership with the Argonne National Laboratory sets the stage for joint synchrotron experiments ensuring a two-way exchange for experiences of significant scientific impact and excellent mentorship from both German and US-based scientists. The project has far reaching societal benefits in creating next generation energy, propulsion and transportation technologies. The educational broader impact of the international research is achieved through i) opportunities for a diverse group of students to experience collaborative research in highly advanced facilities with mentoring from world-known scientists and peers ii) training of the next generation of interdisciplinary global scientists to support advanced gas turbine and hypersonic initiatives iii) outreach through activities with local high school and middle school students, interactive blogs and podcasts as well as through a new initiative of interactive Skype sessions which connects German scientists to US classrooms. This IRES project facilitates international experiences for U.S. students, through collaborative research between the German Aerospace Center (DLR) and the University of Central Florida (UCF) to extend the durability and high temperature capability of material systems for leading edges, turbine and combustor components and to elucidate impurities and diluents on combustion performance of new fuels. Meanwhile, such directed efforts can also enhance the area of power generation, removing pathways to NOx, combating CO2 emissions and increasing efficiency through sequestration. The advancement of transformational technologies in these areas can be met through dedicated, interdisciplinary research focus on i) new combustion strategies including exceptional fuel reactions; ii) design and characterization of materials that can withstand high and ultra-high temperatures with integrity and durability and iii) thermal management strategies that leverage additive manufacturing to support both materials and combustion needs. Results serve to enhance the design of optimized combustion performance that need reliable material systems to enable advanced technologies in propulsion and energy.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
