Abstract

Seal failure in aerospace applications-creating a global open-source database Seals are essential components used in numerous applications across engineering. A seal is a component that impedes the flow of fluid through a given system. The word 'impede' holds emphasis as there is no such thing as a zero-leakage seal. All seals leak, even if it is as low as 1 mm3/year and referred to as "emission". [1] Although seals serve many purposes in aerospace applications, their main purposes are to restrict leakage out of a system and to prevent contaminants from entering a system-that is, keeping fluids in and keeping debris out. When selecting a seal for a specific application , many criteria require consideration. These include installation and assembly, temperature and pressure, contact and non-contact configurations , wear, and rotational and surface speeds. However, the perfect seal does not exist and the specific requirements crucial for optimum performance in a specific application must be considered when selecting the seal.
