Tīmeklis2024. gada 13. apr. · Jak uvádí server Slashgear, průměrný proudový motor používá k nasávání vzduchu řadu ventilátorů. Tento vzduch se pak stlačí, vstříkne se do něj palivo a zapálí se. Síla tohoto zápalného plynu je vytlačována ze zadní části motoru a vytváří tah, který pohání proudový motor vpřed. ... Nejrychlejší scramjet ... TīmeklisA ramjet, or athodyd (aero thermodynamic duct), is a form of airbreathing jet engine that uses the forward motion of the engine to produce thrust. Since it produces no thrust when stationary (no ram air) ramjet-powered vehicles require an assisted take-off like a rocket assist to accelerate it to a speed where it begins to produce thrust. Ramjets …

Scramjet engines are a type of jet engine, and rely on the combustion of fuel and an oxidizer to produce thrust. Similar to conventional jet engines, scramjet-powered aircraft carry the fuel on board, and obtain the oxidizer by the ingestion of atmospheric oxygen (as compared to rockets, which carry both fuel and an oxidizing agent). This requirement limits scramjets to suborbital atmospheric p…
