Connecting Researchers to the Warfighter Unclassified President Obama, State of the Union, January 25, 2011 “The first step in winning the future is encouraging American innovation. Our free enterprise system is what drives innovation. But because it’s not always profitable for companies to invest in basic research, throughout our history, our government has provided cutting-edge scientists and inventors with the support they need. Two years ago, I said that we needed to reach a level of research and development , we haven’t seen since the Space Race. And in a few weeks I’ll be sending a budget to Congress that helps us meet that goal. We’ll invest in biomedical research, information technology, and especially clean energy technology -- an investment that will strengthen our security, protect our planet, and create countless new jobs for our people. Maintaining our leadership in research and technology is crucial to America’s success. But if we want to win the future - - if we want innovation to produce jobs in America and not overseas – then we also have to win the race to educate our kids. Over the next 10 years, with so many baby boomers retiring from our classrooms, we want to prepare 100, 000 new teachers in the fields of science and technology and engineering and math. ” Investment in Basic and Applied Research is a commitment to the future warfighter Hypersonics Briefing M 0524/2011 Page-2
Thoughts from the Secretary of Defense Unclassified Secretary Gates, Budget Rollout Hearing 14 Feb 2011 “These budget decisions took place in the context of a nearly two year effort by the Do. D to reform the way the Pentagon does business – to change how and what we buy…We have protected programs that support military people, readiness, and modernization…We still live in a very dangerous and often unstable world. Our military must remain strong and agile enough to face a diverse range of threats – from nonstate actors attempting to acquire and use weapons of mass destruction and sophisticated missiles, to the more traditional threats of other states… ” “Directed Do. D to fund 2% real growth in Basic Research and to maintain stable funding in the rest of S&T for FY 12 -FY 16. In real terms, the FY 12 S&T budget request is almost 29% greater than the request in FY 2000. ” OSD/PA News Release, 2/14/11 Hypersonics Briefing M 0524/2011 Page-3

Hypersonics Research … A Study in Mixed Results • Successes – X-15 – Space Shuttle – X-43 A • Did not meet goals – Aerospaceplane – NASP – X-33 Photos courtesy NASA, Richard Hallion Hypersonics Briefing M 0524/2011 Page-10 Unclassified
What is the Problem? – Hypersonics Research—One Size Does not Fit All − Hypersonic Cruise Missile not the Same as Two-Stage to Orbit − Help the Do. D Walk Before Running − Use Early Case Demonstrations to Build the Tech Base Hypersonics Briefing M 0524/2011 Page-11 Unclassified
Diagnosis • What’s worked… reasonable scope and risk – Space shuttle re-entry as a hypersonic glide vehicle (unpowered), limited maneuvering at high Mach numbers – X-15 rocket powered, moderate hypersonic Mach numbers (Mach 4 -6+) – X-43 A focus on 2 D scramjet propulsion • What hasn’t… bridges too far – Large scale, single-stage to orbit launch vehicles and space planes – Very large propulsion systems (especially air breathing) with limited experience • Key challenge… scramjet propulsion – – Hypersonics Briefing M 0524/2011 Page-12 Limited flight test data (X-43 A total of 17 seconds with hydrogen fuel) Hydrocarbon fuels Scale up? Combined cycles? Air vehicle challenges – longer flight times in severe environment Unclassified
Success!!! X-51 A First Flight (All results preliminary) • Release at 49. 5 k ft, Mach 0. 78 (nominal) • Boost to Mach 4. 8 (nominal) • Booster separation (nominal) • Engine ignition at Mach 4. 7 (nominal) – Light on ethylene and transition to JP-7 • Climb and acceleration to Mach ~4. 9 – Engine performance nominal • Lost telemetry at 210 seconds, vehicle still accelerating – Flight terminated as planned 5 seconds after loss of telemetry Hypersonics Briefing M 0524/2011 Page-13 Unclassified
