The advent of high performance aircraft has presented the Engineering analyst with a formidable array of problems. At the present time numerical methods are used to provide a significant amount of the data in the design and analysis of aircraft. In general a wide range of flight conditions must be modeled in a cost effective manner. In an effort to improve the cost effectiveness of these preditions one must consider carefully the balance between apects of the numerical solution procedure and the costs required by each particular solution mehtod. Important aspects of the numerical solution procedure include both the solution algorithm used and the numerical models used to describe the ral "in-flight" physics. This paper briefly discusses the performance of an unstructured numerical solver, using turbulence model closures based on the Bousinesq hypothesis, on two unsteady aerodynamic flows.
