碩士 / 國立虎尾科技大學 / 航空與電子科技研究所 / 103 / As for the release of stores from the aircraft, it is important that the target is hit and destroyed by the stores. However, it will not be allowed and expected if the mother aircraft is hit and damaged by the store it releases. Consequently, smooth separation of store and aircraft is also concerned. In this article, the commercial software ESI CFD FASTRAN is applied to study the parametric effects of supersonic flows around multiple stores with fins released from a wing. The three-dimensional, unsteady Euler is solved in the Cartesian coordinate. The Chimera multi-block grid system is utilized, and grid communication among multiple blocks is automatically implemented. To evaluate the accuracy of the present calculation, the calculated one-store instantaneous trajectory of center of gravity of store, angles of roll, pitch and yaw, velocity and angular rate are compared with those of experimental data. The satisfactory agreement is achieved. Then, the number of store is increased. As far as the multiple stores are concerned, four parameters are carried out to investigate the parametric effects of separated stores. The first is to increase the forward ejector force and keep rearward ejector force invariant, the second is to increase not only the forward ejector force but also the rearward ejector force, the third is to vary the angle of attack while the last is to change the Mach number.
