Hydrogen powered hypersonic flight is moving from speculative concept to detailed engineering plan, with aerospace startups and research partners sketching out aircraft that could cross continents in ...

Hypersonic flight could one day make long-haul travel as quick as a short movie. Researchers are testing how turbulence behaves at extreme speeds, a critical hurdle for designing these aircraft. Their ...

Hypersonic vehicles — aircraft that can reach speeds of Mach 5 and beyond — are subject to extreme conditions while they are in flight, requiring strong yet aerodynamic materials to keep them both in ...

GE and Lockheed ground tested a new air-breathing hypersonic jet engine capable of powering missiles to speeds well in excess of Mach 5 in a smaller, cheaper, lighter, and more efficient package than ...
