Explaining a Plane on Instagram: "@explainingplanes shows you everything you need to know about planes 🧠✈️ Turbojet, ramjet and scramjet engines represent three distinct engineering approaches to pushing the limits of speed in aviation. In a turbojet, compressors and turbines increase the pressure of incoming air and combustion occurs at subsonic speeds. This configuration operates efficiently over a wide range of speeds but loses effectiveness at very high velocities. In a ramjet, there is no
