They usually have a shaped clay nozzle formed into the end of the engine tube. This differs slightly for the intended duration of the engine.
Ejector nozzles are used in jet engines. They are the simpler of the nozzles used and are more conventional that iris nozzles. Ejector nozzles are part of a group that includes ejector, iris, rocket, and low-ratio nozzles.
The thrust of a solid rocket engine depends on the composition of the solid fuel and the rate at which it is burned, and to some extent on the way the gases are directed by the exhaust nozzles. The same material can be burned at different rates to produce more or less thrust, and the nozzles (also used for directional control) can divert this thrust to control velocity and stability.
A rocket exhaust nozzle that can be aimed in any direction.

The two main types of rocket engines are Solid fuel rocket engines and Liquid fuel rocket engines.

you have to glue bits and pieces together ;-)
Rocket engines are not air breathing engines and hence they can be propelled into space.
The nozzle directs the blast from the burning fuel into a propulsion cone that is the most efficient for the engines output. Without a cone the flow of energy would be unpredictable and would not propel the rocket in the direction desired.
