The Reaction Engines Scimitar is a derivative of the SABRE engine technology, but intended for jet airliners (the Reaction Engines LAPCAT A2 concept), rather than space launch applications. Consequently, most of the Scimitar engine technology is similar to SABRE but designed for much longer life. [ 1 ]
The Scimitar engines use technology related to the company's earlier SABRE engine, which is intended for space launch, but here adapted for very long distance, very high speed travel. [citation needed] Normally, as air enters a jet engine, it is compressed by the inlet, and thus heats up. It needs much more power to compress that heated air ...
The FV107 Scimitar is one of the CVR(T) series of vehicles. The first prototype was completed in 1971. [3] After being accepted for service in 1973, deliveries to Belgium and the UK commenced in 1974. [3] Initially, the engine was the Jaguar J60 4.2-litre 6-cylinder petrol engine, the same as used by several Jaguar cars.
Reaction Engines Limited (REL) was a British aerospace manufacturer founded in 1989 and based in Oxfordshire, England. [1] The company also operated in the USA, where it used the name Reaction Engines Inc. (REI). REL entered administration on 31 October 2024. Both REL and REI ceased operations and laid off the bulk of their staff.
The LEP was carried out on the Scimitar and Sabre reconnaissance vehicles, Spartan APCs, Sultan command post vehicles, Samson recovery vehicles, Samaritan ambulances and the Striker anti-tank vehicle. The major part of this upgrade was the replacement of the Jaguar 4.2-litre petrol engine by a more fuel efficient Cummins BTA 5.9 diesel engine. [11]
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. [1] It was funded by the European Commission research and development fund (rather than ESA), and cost 7 million euros. [2] [3]
[5] [6] The engine is designed to achieve single-stage-to-orbit capability, propelling the proposed Skylon spaceplane to low Earth orbit. SABRE is an evolution of Alan Bond's series of LACE-like designs that started in the early/mid-1980s for the HOTOL project. [7] Reaction Engines went into bankruptcy in 2024 before completing the project. [8]
The Type 508 was the first Scimitar ancestor; it shared the broad layout of the unflown Type 505, both possessing a straight-wing paired with a V-tail and twin jet engines. [8] The redesign was done in a manner that, if desired, an undercarriage-less configuration was still viable; furthermore, it was designed in such a manner that it could be ...
