Fast Aerodynamic Simulation for Military Procurement
Abstract
Numerical simulation of airborne vehicle performance is of increasing importance to military. Such simulations become integral to procurement strategy when they can provide fast answers to performance related inquiries. Except for being able to identify the more challenging real time turbulence scales and other grid dependent issues related to complex configuration studies, the computational methods have matured to a stage where they are bringing virtues of different disciplines together, to couple efficiently for the best possible design. Increasing computational power has provided modelers the ability to seek more knowledge per design cycle and to increase the actual number of cycles. This article discusses some of the defense related projects in which IAR has used simulation techniques to provide timely answers to such questions as the performance of advanced missile systems, prediction of trajectories of stores released from rotor based and fixed wing aircraft and the use of optimization techniques for aircraft performance. The paper also emphasizes that for most standard performance studies, one may be able to use lower order computational methods to reach satisfactory conclusions.
