ROCKET ENGINES
A rocket engine is a device that produces a force by pushing gases at high speed out of a nozzle. Rocket engines burn chemicals such as petroleum and liquid oxygen at very high pressures and temperatures to turn the chemical energy into motion.
A rocket engine is a type of jet engine that uses only stored rocket propellant mass for forming its high-speed propulsive jet. Rocket engines are reaction engines, obtaining thrust in accordance with Newton's third law.
Rockets create thrust by combining liquid fuel and liquid oxygen. If you get rid of the liquid oxygen, you can have a smaller, lighter, more efficient aircraft and carry more! Some people predict that a supersonic combustion ramjet's engine will reach high speeds of mach 15 or higher. That could turn a trip from Tokyo to New York into a two hour flight. Normally this would be a 18-hour flight.
NASA's Hyper-X program is working to develop scramjets into a practical technology. The X-43A, a 12-foot long scramjet-powered research vehicle, was constructed by MicroCraft Inc. The company fabricated three X-43A aircrafts for NASA to be flown aboard modified Pegasus rockets developed by the Orbital Sciences Corporation. The Pegasus is dropped by a B-52 aircraft and launched to an altitude of over 90,000 feet, where the X-43A is released and flown under its own power.
RAMJETS AND SCRAMJETS
RAMJET ENGINES
A ramjet, sometimes referred to as a flying stovepipe or an athodyd, 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.
RAMJET ENGINE
A ramjet engine provides a simple, light propulsion system for high speed flight. Likewise, the supersonic combustion ramjet, or scramjet, provides high thrust and low weight for hypersonic flight speeds.

SCRAMJET ENGINES
A scramjet engine is an improvement over the ramjet engine as it efficiently operates at hypersonic speeds and allows supersonic combustion. It is known as Supersonic Combustion Ramjet, or Scramjet. ... The Scramjet engine designed by ISRO uses Hydrogen as fuel and the oxygen from the atmospheric air as the oxidiser.
SCRAMJET ENGINE
As in ramjets, a scramjet relies on high vehicle speed to compress the incoming air forcefully before combustion (hence ramjet), but whereas a ramjet decelerates the air to subsonic velocities before combustion, the airflow in a scramjet is supersonic throughout the entire engine.
PICTURE
JET ENGINES
A jet engine is a reaction engine discharging a fast moving jet that generates thrust by jet propulsion. This broad definition includes air breathing jet engines, and non air breathing jet engines. In general jet engines are combustion engines.
The core of the turbine comes from the CF6-6 jet engine, which generates 40,000 pounds. The GE9X is the largest jet engine in the world, and is as wide as the body of a Boeing 737, but it's not the most powerful. That title belongs to its parent, the GE90, which today powers most Boeing 777 planes.
