This model is a 3d diagram of a revolutionary rocket engine design known as the full flow staged combustion cycle. Only 3 times in history has this design ever been attempted. Only recently has it been successful and flown. The design works by burning both fuel and oxidizer in non-stoichiometric conditions in a preburner to power a turbopump on each side. Each turbopump then increases the flow of either fuel or oxygen, powering a positive feedback loop. The exhaust from each preburner gets piped into the main combustion chamber to explode a second time, resulting in high efficiency and thrust. This model is an extreme oversimplification of the design but encapsulates the conceptual mechanics.
