Applying Jet Interaction Technology

The state of the art in aerodynamics engineering associated with the design and/or evaluation of reaction controls on flight vehicles operating in the atmosphere is reviewed. Various configurations of the aerodynamics interference problem are described to partition domains of the problem. To maintain an applications frame of reference, those descriptions are in the context of the dominant phenomenology observed under differing flight environment and vehicle geometry combinations. Following that, approaches to predicting or evaluating interference effects are reviewed. Approaches to the design of subscale wind-tunnel tests are discussed with a view toward relating appropriate scaling law approximations to the different domains of dominant phenomenology. Then results, found in the literature, describing the evolution of analytical and computational modeling are reviewed. Finally, some conclusions and observations on the state of the art are offered.
