Helicopter Engine Development New Standards for the '80S

The T700 Development and Maturity Program is an example of a new philosophy underlying engine development and qualification programs in which mission-oriented and accelerated engine testing plays a key role where engine reliability, maintainability and life cycle costs are stressed along with engine performance and weight. The T700 Development and Maturity Program included a number of specially designed engine tests to assure early maturity of the engine prior to production and to demonstrate parts life integrity well in advance of significant field experience. These tests, such as the Low Cycle Fatigue Test (LCF), Accelerated Simulated Mission Endurance Test (ASMET), Accelerated Mission Test (AMT) and Stress Rupture Test were conducted in addition to the Standard 150-hour Model Qualification Test (MQT), and were designed to exercise the engine components through one or more engine lifetimes at an accelerated pace.
