How do rocket engines not melt?

Techniques include: Regenerative cooling, where the propergols (both propergols, or just the fuel) are pumped through a jacket around the nozzle before going into the combustion chamber. This cools down the nozzle, and heats up the propergols that may be cryogenic in nature.

How does a rocket engine start?

It all starts with electrical current running through an igniter wire. The electrical resistance of the igniter wire causes heat as the current passes through. That heat is enough energy to push what’s called the “pryogen” into ignition. You can think of the pryogen as being like the stuff on the head of a match.

How many types of rocket engines are there?

There are two main categories of rocket engines; liquid rockets and solid rockets. In a liquid rocket, the propellants, the fuel and the oxidizer, are stored separately as liquids and are pumped into the combustion chamber of the nozzle where burning occurs.
