"Gas generator cycle. But it´s for babies (Merlin pt2)"
Rocket boom booms are a fascinating field, and one of the key technologies that make modern rockets possible is the gas generator cycle. This cycle is used to power turbopumps, which work by pushing hot gas into a turbine. Connected to a shaft it pumps fuel and creates boom booms.. Let’s dive into the details of how the gas generator cycle works and why it’s important.
What is the Gas Generator Cycle?
The gas generator cycle is a method used in liquid rocket engines to drive the turbopumps that supply fuel and oxidizer to the combustion chamber. In this cycle, a small portion of the propellant is burned in a separate combustion chamber called the gas generator. The hot gases produced are then used to drive the turbine connected to the turbopumps.
How Does It Work?
Fuel and Oxidizer Supply: The cycle begins with the fuel and oxidizer going to the gas generator. These propellants are typically the same as those used in the main combustion chamber.
Gas Generation: In the gas generator, a controlled combustion process occurs, producing hot gases. This combustion is less efficient than in the main chamber because it operates at a lower pressure and temperature. It is more like a side engine. Not the main one.

Merlin engine: Rocket science can be easy (sophiasstarlog.blogspot.com)Turbine Drive: The hot gases from the gas generator are directed to a windmill (turbine). The turbine extracts energy from these gases, converting it into mechanical energy to drive the turbopumps through sticks otherwise known as crankshafts.
Exhaust: After passing through the turbine, the gases are expelled, usually through a separate exhaust nozzle. These gases do not contribute to the thrust of the rocket but are essential for powering the turbopumps.
Advantages of the Gas Generator Cycle
- Simplicity: The gas generator cycle is relatively simple compared to other cycles like the staged combustion cycle. This simplicity can lead to easier design and manufacturing processes. Oh boy do I absolutely don´t want to write a blog post on that.
- Reliability: Due to its straightforward design, the gas generator cycle is known for its reliability. This makes it a popular choice for many rocket engines. Such as the merlin engine! Used for the falcon 9, 11, and much more!
- Cost-Effective: The simplicity and reliability of the gas generator cycle can also translate to cost savings in both development and operation. Since Elon musk created this with the idea of cheap and simple.
Conclusion
The gas generator cycle is a crucial technology in the field of rocket propulsion. Its simplicity, reliability, and cost-effectiveness make it a popular choice for many rocket engines. Understanding this cycle helps us appreciate the engineering marvels that enable space exploration and satellite deployment. Remember, shoot for the stars starlogers!
