Two-body aerodynamic analysis is crucial whenever there is a store that separates from its parent body, i.e., the aircraft. Any time that a new aircraft is developed or an existing one undergoes some modification with its associated store, it has to undergo a meticulous analysis to predict the path of the separated store across a range of operating parameters (freestream conditions). The present work demonstrates an efficient albeit approximate semi-empirical technique that employs a reduced-order model based on proper orthogonal decomposition in conjunction with a multi-domain-decomposition approach for predicting the flow field around a store-aircraft dyad. Encouraging preliminary results are obtained in the verification that is pursued on a two-dimensional problem for simplicity. The approach can be readily extended to three-dimensional problems as well. [ABSTRACT FROM AUTHOR]
