✦ Synopsis

Viscous computational fluid dynamic simulations are used to predict the aerodynamic coefficients and flowfield for a missile with grid fins. A grid fin is an unconventional lifting and control surface that consists of an outer frame supporting an inner grid of intersecting planar surfaces of small chord. The calculations are made at Mach numbers of 0.7 and 2.0. Full NS equations are discretized into finite volume form and solved by an algorithm in LU-SGS. The comparisons between computations and experimental data are made, the detailed flow structure near grid fins is showed and examined.
