Web19 de dez. de 2024 · As for the comparison between ramjet and scramjet, it is actually not true that scramjets are more efficient that ramjets, as a blanket statement. It depends on the speed: Below Mach 4, scramjets don't even work, so talking about their efficiency makes no sense. Between Mach 4 and Mach 5, ramjets are more efficient than scramjets. 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… quackity and bbh fanart
