Lateral Reaction Jet Flow Interaction Effects on a Generic Fin- Stabilized Munition in Supersonic Crossflows.

摘要

The flow interaction effects from a jet issuing into a supersonic crossflow were investigated computationally for the case of a flat plate and a generic fin-stabilized projectile. For both configurations, simulations were performed at several Mach numbers and jet total to freestream static pressure ratios (PRs). In the flat plate case, the jet force was generally amplified, with a strong dependence on PR and the freestream Mach number. In the projectile configuration, seven jet locations along the missile axis were investigated at three supersonic crossflow Mach numbers and five angles of attack in the range 10 deg.
