Abstract:

Five tasks were initiated to study the aerodynamic interference between stores and aircraft. Both viscous and inviscid calculations were made. Steady state interference calculations matched well with experimental results and with other computational results. Unsteady time-accurate inviscid results showed the feasibility of using the Chimera scheme to simulate store separation. Free-fall calculations were made, demonstrating the ability to compute the new position of the store from the aerodynamic forces and moments on the store after its release from the aircraft.
