“…us, the CFD calculation results of the previous deformation step can be applied to the next step as the initial value, and the iteration step of CFD calculation can be decreased. In general, the computational results tend to convergence with 6-7 iteration steps which is 1.5 to 2 times to its rigid CFD counterpart [31][32][33].…”

Diamond back wing is subjected to large deformation while gliding, which significantly changes characteristics of the lift as well as the static stability. For this reason, conventional rigid aircraft assumption cannot meet the requirements of the aerodynamic analysis of such aircrafts for accuracy. In this paper, based on CFD/CSD methods, the static aeroelasticity of a small diameter bomb with diamond back wing was studied. The results showed that static aeroelastic effects cause the slope of lift line to drop by 21% and the aerodynamic centre to move backwards by a 1.5% bomb body length, which will deviate the actual flight performance from the design point, thereby decreasing the cruise efficiency and the cruise range.
