Opportunity Summary:
NASA Headquarters released this grant opportunity as part of Amendment 3 to the NASA Aeronautics Research Mission Directorate (ARMD) Research Opportunities in Aeronautics (ROA) 2015 NASA Research Announcement (NRA), posted through the NSPIRES system. The specific slice of the NRA covered here is Appendix A.2, which supports foundational research for NASA's Advanced Air Transport Technology Project (AATT1). In practical terms, the solicitation is aimed at early-stage, enabling work that can move the state of the art in aircraft electric power conversion, particularly inverter technologies that can meet the demanding efficiency, power density, and operating-environment requirements of future air transport aircraft.
The opportunity identifies two focused technical topics. The first topic is an "Ambient High Temperature High Efficiency/High Specific Power Inverter for Aircraft Applications." This centers on inverter concepts and designs that can operate at ambient (non-cryogenic) conditions while tolerating elevated temperatures typical of tightly packaged aircraft propulsion or power electronics bays. The emphasis on high efficiency and high specific power points to solutions that minimize electrical losses and heat generation while delivering more power per unit mass, which is critical in aviation where weight translates directly into range, payload, and operating cost. Work under this topic would generally be expected to address challenges such as thermal management, packaging, high-temperature components and materials, switching devices, and architectures that improve power density without sacrificing reliability.
The second topic is a "Cryogenic High Efficiency/High Specific Power MW Class Aircraft Inverter." This is aimed at megawatt-class inverter technology intended to operate in cryogenic environments, consistent with aircraft concepts that may use cryogenic fuels or cooling to enable higher electrical performance. Cryogenic operation can allow certain electrical components to perform better (for example, reduced resistance and potentially higher current densities), but it also introduces engineering hurdles including insulation behavior at low temperatures, mechanical stresses from thermal contraction, reliability across thermal cycles, and integration with cryogenic systems. The solicitation's focus on MW-class performance signals interest in power conversion suitable for high-power electrified propulsion, hybrid-electric architectures, or distributed propulsion concepts where megawatt-scale electrical conversion becomes a key enabling capability.
Administratively, the funding opportunity number is NNH15ZEA001N with the AATT1 designation, and the funding instrument type is a grant. The activity category is Science and Technology and other Research and Development, and it is associated with CFDA 43.002 (Aeronautics). There is no cost sharing or matching requirement indicated, which means proposers generally are not required to contribute non-federal funds as a condition of award, though specific project structures and any voluntary cost share would be addressed in the full solicitation text.
Eligibility is described as "Unrestricted," meaning it is broadly open to different types of applicants, subject to any clarifications in the full announcement under the eligibility section. That typically implies universities, industry, nonprofits, and other research entities may apply, assuming they meet standard federal and NASA solicitation requirements laid out in the NRA. The announcement was posted April 13, 2015. A Notice of Intent (NOI) was due April 21, 2015, and full proposals were due May 26, 2015. The archive date listed is June 25, 2015, reflecting that this is a past solicitation cycle, but the summary still captures the scope and intent of the call as issued.
For access and support, NASA directed applicants to the full text on NSPIRES and noted that written responses to questions would be posted on the solicitation website. Grants.gov technical support was available through the Grants.gov Contact Center at 1-800-518-4726. NASA points of contact included the Glenn Research Center distribution list email GRC-DL-FixedWing-LTN@mail.nasa.gov, along with named roles for technology, NRA management, and procurement, indicating that both technical and administrative questions were expected and handled through established NASA channels.
