+ Flight Tests Measure Shock Waves
NASA is concluding a series of flight tests to measure shock waves generated by an F-15 jet to validate computer models that could be used in designing quieter supersonic aircraft.
+ Alternative Fuels Are Put to the Test
NASA and 11 other research groups are testing two non-petroleum-based jet fuels in the pursuit of alternative fuels that can power commercial jets and address rising oil costs.
+ New National Hypersonic Science Centers Named
Two exploration agencies find common ground in finding ways to reduce
the level of sonic booms so that future supersonic flight over land
might be possible.
+ NASA and Partners Test X-48C in Historic Wind Tunnel
A historic wind tunnel at NASA's Langley Research Center in Hampton,
Va., has been pressed into service one last time to help test the
prototype of a new, more fuel-efficient, quieter aircraft design.
+ Inflatable Heat Shield is "Go for Launch"
A successful NASA flight test has shown that a spacecraft returning to
Earth can use an inflatable heat shield to slow and protect itself as it
enters the atmosphere at hypersonic speeds.
+ NASA Continues Sonic Boom Tests
Tests to measure the impact of sonic booms expanded to include sonic boom-measuring mannequins with microphones inside their ears.
