Requirements and Constraints in the Development and Qualification of Gas Turbine Engines for the Navy

An improved approach to the development and qualification of aircraft turbine engines has been developed by the Navy. The approach places emphasis on durability testing throughout the engine development program. This testing is intended to assure that structural requirements have been achieved upon the introduction of new engines into service. The approach utilizes three different types of durability tests each of which is intended to address a separate aspect of the overall durability problem.
