A launch vehicle uses a turbopump that is driven by a hot gas turbine. Due to high levels of horsepower, RPM, flow rates and pressures in this system, specific design features, materials, and fabrication methods must be used to ensure high performance as well as space flight levels of reliability. For static sealing applications in this area, metal seals are used to prevent leakage of a fluid through a joint that has no relative motion of the mating surfaces.

Description
Powered, microsurgical devices is a trend that began in the early 2010s with developments in minimally invasive surgery providing the benefits of smaller incisions and more versatile solutions for surgeons, including better patient recovery times. Since then, the industry has seen a rise in miniature motors in surgical tools, pumps and ventilation equipment. Since these tools must be precise, reliable and withstand over a thousand autoclave cycles, the micromotors operating the tools are placed under challenging and strenuous demands.

Description
Launch vehicles are most often propelled using fluids with liquid oxygen being the most common oxidizer and fuel being liquid hydrogen or kerosene and most recently liquid methane. All these fluids (except kerosene) are commonly stored at cryogenic temperatures.
Sealing is critical when liquid oxygen or hydrogen are involved since they are easily ignitable. Any small amount of leakage can create a hazardous situation, which can lead to a potential explosion of the whole launch system. Leakage requirements are therefore quite stringent.
