Ramjet Engine Functioning
- Ramjets breathe air, in contrast to their primary rival for speed, the rocket, which burns fuel using internal oxidizers such as ammonium nitrate, potassium chlorate, or ammonium chlorate.
- Ramjets must go through the atmosphere, in contrast to rockets, which may operate in the almost vacuum of space.
- Ramjets work by harnessing ram pressure, the natural air compression brought on by an aircraft's high speed.
- Hence they must operate at very high speeds, around Mach 2.5 -- 3.0, or three times the speed of sound.
- As a result, they rely on other vehicles or booster rockets to accelerate them. Hybrid engines are primarily used in standalone ramjet aircraft.
- The controlled explosions power jets.
- That may seem odd until most automobile engines operate similarly: Air is drawn in, compressed, combined with fuel, ignited, and then the piston gets pushed!
- Use continuous combustion, in which fuel and air are continuously mixed and burned, in contrast to the cyclical or intermittent combustion that occurs in gasoline and diesel engines.
How does a ramjet engine work?
A Ramjet engine's combustion chamber has air moving through it at subsonic speeds. Ramjets are more effective than rockets across long distances, but they have a severe drawback: they are worthless at low speeds.
