Validation of a multipoint approach for modeling spin aerodynamics
Journal of Aircraft, 1995during the spin. The rolling-moment and yawing-moment coefficient variations were relatively small, and thus, the steadyspin assumption is reasonable for these quantities. In contrast is the large amplitude of the pitching moment coefficient trace. The maximum and minimum values of the free-spin results are approximately equal to the rotary balance ...

Complex Aerodynamics Behavior of High Spin APFSDS Projectile
Journal of Applied Mechanics, 2013The supersonic aerodynamics of a high spin armor-piercing fin-stabilized discarding sabot projectile (APFSDS) is numerically and experimentally investigated. Classically, using a 120 mm smooth bore gun, the value of the nondimensional steady spin rate of the inflight APFSDS projectile is about 0.01.

Longitudinal Aerodynamics of a Canard Guided Spin Stabilized Projectile
Advanced Materials Research, 2012Navier–Stokes simulation is performed on a canard guided spinning projectile for different attack angles and circumferential position angles of canard over the Mach number range of 1.8–2.2. The computational Magnus moment coefficients of test case are validated with available experimental data of a Secant-Ogive-Cylinder-Boattail (SOCBT) configuration ...

Three dimensional numerical study of soccer ball aerodynamics at different spin conditions
, 2021Aerodynamics of a soccer ball was studied with a three dimensional numerical approach using ANSYS Fluent. The ball used was a 32 panel soccer ball which was modeled in CAD and it was validated numerically by a 3D analyzing technique solving Reynolds ...
