Problems with scramjets
Webb5 Answers Sorted by: 14 No. The fastest airbreathing engines we have are scramjets (supersonic combustion ramjet), i.e. a duct that compresses the air while allowing it to flow at supersonic speeds. The fastest scramjet flight so far reached Mach 5, … Webb16 jan. 2024 · The problem is that a scramjet engine doesn’t actually work until it’s physically moving at near hypersonic speeds. Any slower than Mach 4 or so, and the incoming air isn’t moving fast enough for...

Webb30 apr. 2024 · Unless it’s a nuclear jet engine what is possible then it isn’t a jet. Jet engines combust fuel and oxygen to heat up and expand air. A nuclear jet engine uses the heat from a reactor to expand air. Jets are a big part of atmospheric travel and they're fun to mess around with. Why would we only get one new type of jet?

Webb14 apr. 2024 · One of the main challenges for scramjet propulsion systems is the efficient and sufficient cooling of the engine’s components. A promising cooling approach could be the method of transpiration / effusion cooling, where the coolant flows through a porous wall prior to entering the engine’s main hot gas flow. hifi rush demoWebbIn a scramjet, this problem is circumvented by slowing the air less dramatically, so that it passes through the combustion chamber at supersonic speed.
