Do Ramjets work in space?
Thus, while rockets can operate in the near vacuum of space, ramjets must fly through the atmosphere. They must do so at very high speeds, too — around Mach 2.5-3.0, or three times the speed of sound — because ramjets work by harnessing ram pressure, the natural air compression brought on by an aircraft’s high speed.
What is purpose of ramjet?
A ramjet, sometimes referred to as a flying stovepipe or an athodyd (aero thermodynamic duct), is a form of airbreathing jet engine that uses the engine’s forward motion to compress incoming air without an axial compressor or a centrifugal compressor.
Is ramjet a rocket?
In both propulsion systems, a rocket is used to bring the ramjet up to speed before it produces thrust. Because the ramjet uses external air for combustion, it is a more efficient propulsion system for flight within the atmosphere than a rocket, which must carry all of its oxygen.

How much fuel does a ramjet use?
In a typical engine, 100 pounds of air/sec. is combined with only 2 pounds of fuel/sec. Most of the hot exhaust has come from the surrounding air.
Why is it called a ramjet?
The ramjet gets its name from the method of air compression-, it cannot operate from a standing start but must first be accelerated to a high speed by another means of propulsion. The air enters the spike-shaped inlet and diffuser (fig. 70) which serve the same purpose as the compressor.
