Store Separation

The classical rigid body 6 DOF capability at Eglin AFB has been completely rewritten. The new (6+) DOF allows moving components relative to non-inertial reference frames during time accurate CFD simulations. An inviscid computational fluid dynamics model was prepared to investigate the separation of a 2,000 lb cluster munition (CBU104) with deployable fins from an F15-E at transonic speed using (6+) DOF. The Mach effects of the store with deployable fins were studied for a given fighter aircraft configuration prior to USAF flight clearance.
