Soot in Rocket Engines
1:15:43 - 1:21:08 (05:24)
Soot can build up in rocket engines due to high pressures and high temperatures, causing clogs in injectors and potentially leading to engine failure. Different close cycle systems can be used to avoid this, such as fuel-rich and oxidizer-rich cycles.

The ideal chemical reaction for a rocket engine is not stoichiometric, as you want to release the lighter molecules to achieve greater speed.

Summary
The ideal chemical reaction for a rocket engine is not stoichiometric, as you want to release the lighter molecules to achieve greater speed. Energy should not be released at the turbine, but rather redirected to a smaller rocket engine to generate even greater speed.

Close cycle rocket engine combustion is important as it determines the flow of fuel and oxidizer through the turbine.

Summary
Close cycle rocket engine combustion is important as it determines the flow of fuel and oxidizer through the turbine. If soot builds up in the engine, it'll clog the injectors and eventually cause the engine to blow up.
