Air breathing engines and model jet engines (complete search)
Air breathing engines and ramjet engines Reaction Engines SABRE The engine SABRE (Synergic Air breathing engine) is designed by Reaction Engines Limited for a hypersonic air hydrogen as fuel engine breathing combined cycle rocket / turboramjet precooled air to propel the project Skylon vehicle to low Earth orbit (LEO). SABRE is the logical continuation of Alan Bond's series of air cycle engine fluid (LACE) and designs such as lace began in HOTOL early/mid-1980s for the project. The SABRE design combines a turbine engine light cycle air jet with a Precooler placed just behind the inlet cone. At high speeds the Precooler cools the heat, a compressed air ram, allowing the jet engine to continue to provide high thrust at high speeds and altitudes. In addition, low air temperature allows the construction of light alloy to be employed which gives a very light engine - essential to achieve orbit. The engine also includes features of rocket engines, whic...
