Introduction to AVT-351: Enhanced Computational Performance and Stability & Control Prediction for NATO Military Vehicles

Abstract

NATO/STO research task group AVT-351 is working on the development of enhanced numerical methods to generate performance and stability & control data sets at feasible cost. Current use of computational fluid dynamics for military vehicle design is limited by tremendous cost and timescales when providing comprehensive data sets. AVT-351 is investigating the application of reduced order modeling techniques for time-dependent maneuver prediction and data set population. Experiments and computational fluid dynamics are used to efficiently provide highly accurate input data for reduced order models built for four different air and sea vehicles. Assessment of different techniques includes applicability for control system and flight dynamics modeling. An overview of objectives, use cases, methods and ongoing efforts as well as initial results is presented.
