Apr 24,  · Chemical rocket engine: A rocket differs from the standard jet engine in that the oxidiser is also carried on board. This means that rockets work in the absence of atmospheric oxygen, i.e. in space. The rocket propellants can be in solid form ignited directly in the propellant storage tank, or in liquid form pumped into a combustion chamber at. The first liquid fuel rocket was produced by Robert Goddard in (How Rocket Engines Work.) The idea of liquid fueled rocket is easy to grasp.
