What is another word for ram jet propulsion?
Pronunciation: [ɹˈam d͡ʒˈɛt pɹəpˈʌlʃən] (IPA) 
Ram jet propulsion is a type of propulsion system that works by compressing incoming air using the vehicle's forward motion and then burning a fuel in the compressed air. There are various synonyms for ram jet propulsion such as "scramjet", "supersonic combustion ramjet", "air-augmented rocket", or "laser ablation propulsion". Scramjet and supersonic combustion ramjet are commonly used interchangeably, though the former is more commonly associated with hypersonic flight. The air-augmented rocket, on the other hand, is a hybrid engine that operates similarly to a ramjet but also uses rockets to provide additional thrust. Lastly, laser ablation propulsion involves the use of lasers to ablate material and generate thrust, particularly for small spacecraft that requires high levels of maneuverability.
