Rocket engine turbopump turbine wheels are highly engineered components designed to extract energy from high-pressure gases to drive the fuel and oxidizer pumps that feed the combustion chamber. Unlike turbochargers in cars, turbopump turbines operate in extreme conditions, often exceeding 1,000°C (1,832°F) with rotational speeds that can surpass 30,000–90,000 RPM, depending on the engine. They are typically made of advanced nickel-based superalloys or single-crystal materials to maintain structural integrity under intense heat and centrifugal forces. Many operate in oxygen-rich or fuel-rich environments, which can be highly corrosive, requiring precision cooling channels and thermal barrier coatings. The efficiency and reliability of a turbine wheel are critical because a turbopump failure usually results in total engine loss. These wheels are designed to be as lightweight as possible while still handling massive loads, making them one of the most complex rotating components ever engineered.
