摘要

European defense companies are eyeing a possible breakthrough in hypersonic engine technology by researchers at the University of Rome, who say lithium hydride is a potential fuel for scramjets. Fuel is a major challenge for air-breathing supersonic combustion ramjets, or scramjets, which have mostly used liquid or gaseous hydrogen to sustain combustion for a few seconds in the supersonic flow of the engine. Tests of lithium hydride (LiH), spinning off from earlier investigations into new high-energy density fuels, "show it has the ideal specific impulse and thrust density predicted for around Mach 7," says Clau-dio Bruno, a professor in the University of Rome's mechanics and aeronautics department. While specific companies Pratt & Whitney Rocketdyne's hydrocarbon-fueled and -cooled scramjet for the X-51A is expected to fly later this year. Solid-fueled alternatives may follow one day. are not identified, Bruno adds that the university is interested in following up with further research.
