Abstract:

Pistol aerodynamics studies require that an aircraft that passes through very different flow regimes throughout the flight period and must have very high maneuver capacity can be controlled with a very limited aerodynamic surface. These difficult goals are typically attempted to be achieved by testing thousands of different wings-body options with a simplified pre-design tool in the pre-design process. In this phase, the alternative bomb geometries found are being studied with HAD analyses in the detailed design phase. But this phase includes a long and expensive pre-processing work load. Therefore, the geometries of the bombs from the pre-design are retained in a limited number. Considering that the pre-design tools are not able to provide a sufficiently accurate solution, it turns out that this transition should be done with less expensive but much more accurate methods. In this study, a new technology was developed, using the Missile-DATCOM format, a popular puzzle aerodynamics rapid analysis program, which can fully automatically create a solution volume and a solution network. With this technology, the bullet environment is pleased with very high quality structural networks. The control wings can be given the desired angles and can be analyzed in the desired flight conditions. HAD analyses have been carried out with a compressable HAD solution that has the ability to solve the Chimera network and is being developed in our laboratory and have been observed a very good match with the results of the experiment.
