X‐51A Scramjet Engine Demonstration
Flight test the AF Hypersonic Technology (HyTech) scramjet i i d h i h d b f l b l iengine, using endothermic hydrocarbon fuel, by accelerating a
vehicle from boost (~M=4.5) to Mach 6+
• Acquire ground and flight data on an actively cooled, self‐controlled operating scramjet engine (rules and tools development)
• Demonstrate viability of an endothermically fueled scramjet in flight
5Public Release #88ABW‐2012‐2266
• Prove viability of a free‐flying, scramjet powered, vehicle (Thrust > Drag)
X‐51A Flight Demonstrations
• Hydrocarbon scramjet to accelerate an air vehicle from Mach 4.5 to Mach 6+ hypersonic cruise4.5 to Mach 6+ hypersonic cruise
• Four flight vehicles fabricated
• First flight test: May 2010First flight test: May 2010
– Accelerated from Mach 4.5 to Mach 5• 90% of criteria met
• Thrust, drag, and thermal performance met expectations
• Unprecedented 143 seconds of scramjet flight data
• Second flight test: June 2011• Second flight test: June 2011• Inlet unstarted during acceleration – relight attempts were unsuccessful
6Public Release #88ABW‐2012‐22666
• Fault Tree Analysis is guiding investigation.
• Third flight scheduled for August 2012
