Abstract :
Normalair-Garrett Limited (NGL) is a pioneer in the technologies of aircrew breathing systems and aircraft environmental control systems (ECS). NGL has comprehensive facilities for research, design, development and environmental testing. These support equipment from initial concept through to mature production. There are many aspects of reliability development testing. These range from endurance testing, possibly carried out at component level during initial development to reduce risk, through to formal combined environment reliability growth testing, or integrity/durability testing, carried out over a period of years to environmentally stress systems or components. This paper discusses NGL´s experience across the range of those disciplines
