Dynamic Supersonic Base Store Ejection Simulation Using Beggar

<p>Static and dynamic conditions throughout various aft supersonic store separation events are examined using the Beggar Computational Fluid Dynamics (CFD) code from Air Force SEEK Eagle Office at Eglin Air Force Base FL. An 8.9o half angle sphere cone is used for the carrier vehicle with an identically shaped store stowed within a hollow compartment in the aft section of the carrier body. Dynamic store separation simulations are implemented at a free-stream Mach of 2.9 with a Reynolds number of Re = 6.9x106/m referenced against carrier base diameter. Analysis covers multiple dynamic separation events along with studies of the carrier/store body at various static conditions and configurations. Dynamic store separation simulations show that a successful store separation is more likely to occur at high angles of attack and high flight angles. When a low angle of attack and low flight angle are combined with inadequate ejection forces it appears that the carrier and store will eventually impact eachother due to the tendency of the store to remain within the low drag wake region of the carrier.</p><p>This work has been selected by scholars as being culturally important and is part of the knowledge base of civilization as we know it.
