Abstract
The move towards reusable launcher vehicles, coupled with the need for increased payload in rocket powered space vehicles is driving rocket engine development to produce smaller and more durable turbopumps, operating at higher speeds and pressures. Seals in these future turbopumps, which supply high pressure liquid oxygen and hydrogen to the combustion nozzle, will be required to operate under more stringent conditions, whilst wearing less. This enormous design challenge, requiring improvements in seal materials and new seal design strategies, is the subject of a current consortium project using BHR Group's sealing expertise.
