The development of a 10-ton thrust liquid oxygen and liquid hydrogen (LOX and LH2) rocket engine is under way at the National Space Development Agency. In advance of the development of a liquid hydrogen turbopump, the National Aerospace Laboratory carried out study and development of a face-contact, bellows mechanical seal for a liquid hydrogen turbopump in co-operation with the National Space Development Agency. The present report describes the fundamental experiments of the mechanical seal (seal diameter:58.5mm) for liquid nitrogen and liquid hydrogen and the development of the mechanical seal for a liquid hydrogen turbopump (seal diameter:43.2mm). The develop...
