Scramjet Engine

I modeled a replica of the scramjet engine. It is designed to be accurate to real scramjet engines and was modeled using the diagrams shown below. For those who don't know, there are three main types of jet engines, turbojet, ramjet, and scramjets. I'll link an explanation video below, but essentially a scramjet is the most efficient and fastest type of engine, capable of reaching speeds of mach 15+ in theory. The engine requires no moving parts and it uses the forward motion of the plane to generate thrust. In other words it has to move really fast (mach 10) for it to begin working. Printing is very straight forward, and no supports are required. It is set to 5% infill, adjust as wished. There are two models to print, there is the actual engine itself, and another engine that has been split in half and scaled to 50%. The split version includes a inscribed diagram of the engine to understand the basis of how it works. It is stupid how simple this engine looks, yet it's capa
