The proposed effort will develop a pair of new analytic techniques that will predict both the Hot Gas Ingestion characteristics for STOVL aircraft and the Steam ingestion characteristics for conventional Naval aircraft. The techniques will allow the design engineer to efficiently predict the anticipated magnitude of these two phenomena without the need for expensive and repetitive model or full scale testing, as is the current practice. The techniques capture the stochastic nature of these phenomena by combining flow dynamics with the development of a probability density distribution for the temperature near the aircraft. For the STOVL application this probabilistic approach will avoid the necessity for expensive and time consuming detailed modeling of the highly chaotic flow around the jet boundaries that lead to Hot Gas Ingestion. The method will also provide a high quality prediction of the velocity outwash from the landing aircraft that could be used to define safe zones for personnel and equipment. While for the Steam Ingestion application this approach will allow the catapult environment to be defined in an analytic design method. The computational efficiency of the proposed methods allows them to be developed as PC based applications leading to a highly portable design package
