Pintle injectors are a crucial component in liquid rocket engines, known for their ability to control thrust and improve combustion stability. This technology has gained attention in recent years ...

This kind of injector smashes to streams of liquid into each other to generate a fine, atomized mist. This is often used to mix fuel and oxidizer to ensure a good combustion in the rocket engine.

Rather than utilizing the staged combustion cycle found in other rocket engines, the Merlin uses a gas generator cycle, with a pintle injector providing combustion stability. Ever Since the Merlin ...
