HIFiRE hypersonic scramjet flight report
ParabolicArc passes on a announcement from NASA Langley about the successful flight of the HIFiRE-2 (Hypersonic International Flight Research Experimentation Program) vehicle, which is a joint effort between NASA, the Air Force Research Laboratory (AFRL) and Australia’s Defence Science and Technology Organisation (DSTO). Boosed by a three-stage sounding rocket, the HIFiRE experiment features a hypersonic inlet, an hydrocarbon-fueled scramjet combustor and a dual exhaust nozzle. As it accelerated from Mach 6 to Mach 8, the flow through the compressor transitioned to supersonic, providing data that can’t be replicated in wind tunnels.
