NASA projects drive critical innovation in and understanding of space, but most cost more and take longer to develop than planned. Today's fiscal environment highlights why that pattern is unsustainable, now more than ever. The NASA Authorization Act of 2010 challenged NASA to develop new technologies for space exploration. This testimony discusses: (1) how the Continuing Appropriations Act of 2011 continues the restrictions in the fiscal year 2010 Appropriations Act, and how they relate to the recently enacted NASA Authorization Act of 2010; and (2) steps NASA should take to increase the likelihood of success as it implements its new direction. This is a print on demand edition of an important, hard-to-find publication.
What are the benefits of electrified propulsion for large aircraft? What technology advancements are required to realize these benefits? How can the aerospace industry transition from today's technologies to state-of-the-art electrified systems? Learn the answers with this multidisciplinary text, combining expertise from leading researchers in electrified aircraft propulsion. The book includes broad coverage of electrification technologies – spanning power systems and power electronics, materials science, superconductivity and cryogenics, thermal management, battery chemistry, system design, and system optimization – and a clear-cut road map identifying remaining gaps between the current state-of-the-art and future performance technologies. Providing expert guidance on areas for future research and investment and an ideal introduction to cutting-edge advances and outstanding challenges in large electric aircraft design, this is a perfect resource for graduate students, researchers, electrical and aeronautical engineers, policymakers, and management professionals interested in next-generation commercial flight technologies.
On November 29-30, 2018, in Washington, D.C., the National Academies of Sciences, Engineering, and Medicine held the Workshop on the Continuous Improvement of NASA's Innovation Ecosystem. The workshop was requested by the National Aeronautics and Space Administration (NASA) Office of the Chief Technologist with the goal of identifying actionable and implementable initiatives that could build on NASA's current innovation culture to reach a future state that will ensure the agency's continued success in the evolving aerospace environment. This publication summarizes the presentations and discussions from the workshop.
