Integrated Approach to Conversion, Verification, Validation and Integrity of AFRL Generic Engine Model and Simulation (Postprint)

摘要

Modern airborne weapons systems face increasingly stringent demands for improved performance and lower cost of ownership. The key to attaining the first of these demands is increased sub-systems integration, which leverages improved component performance to make even greater improvements in overall weapons system capability. Research is essential to gaining a fundamental understanding of the behavior and control of these highly integrated systems. Progress towards meeting the affordability demands for these systems is also being closely scrutinized. Recognition and control of ownership costs has become increasingly difficult in the face of increasing systems complexity. It may be possible to reduce the amount of physical engine test required in a typical gas turbine engine development program through the use of simulation and modeling techniques in a virtual engine test cell. However, in order to establish the credibility of a simulation and modeling approach to virtual engine test, carefully documented verification and validation (V & V) activities must be undertaken during model development.
