Keywords: manoeuvre loads, aeroelastic simulation, computational fluid dynamics

Efficient loads computation method based on aeroelastic simulation applicable for multiple store configurations is presented. Limitation of structured multiblock CFD methods, grid generation for complex configuration, is overcome using modular approach with non-matching boundary technique between stations. Large control surface deflections for trimming are accomodated using similar approach.
