An extended parametric CFD study of supersonic missile grid fins with varying sweep angles using HiFUN solver

Key Points

• The analysis reveals significant aerodynamic performance variation due to changes in sweep angles of the grid fins.
• Key findings include fluctuations in drag coefficients across a range of different sweep angles evaluated for the missile fins.
• Assessment using parametric computational fluid dynamics (CFD) demonstrates the influence of geometric variations on flow patterns.
• This work highlights the need for advanced modeling techniques to fully understand flow interactions around supersonic missiles.
