LAPCAT
LAPCAT (Long-Term Advanced Propulsion Concepts and Technologies) was a 36-month European FP6 study to examine ways to produce engines for a Mach number 4-8 hypersonic flight aircraft. The project ended in April 2008. It was funded by the European Commission research and development fund (rather than ESA), and cost 7 million euros.
LAPCAT II, a 10 million euro, four-year, follow on project, started in October 2008. The study aims to refine some of the results of the first study "allowing the definition of a detailed development roadmap" of a Mach five vehicle.
Two major technologies were to be considered:
Key objectives were the definition and evaluation of:
Intended results were:
Among the several vehicles studied, only two novel concepts were retained for LAPCAT II: a Mach five vehicle and a Mach eight vehicle.
One possible supersonic transport aircraft being researched as part of this project was the A2 by Reaction Engines Limited. The researchers studied at an aircraft capable of flying from Brussels (Belgium) to Sydney (Australia) in 2–4 hours, significantly reducing journey times across the globe.
To attain and maintain such high speeds, Reaction Engines Limited would need to develop its newly designed concept engine called the Scimitar, which would exploit the thermodynamic properties of liquid hydrogen. The engine would be theoretically capable of powering the A2 to a sustained Mach 5 throughout flight with an effective exhaust velocity of 40,900 m/s or specific impulse of 4170 s, SFC 0.86 lb/(lbf⋅h).
