This article goes through numerical trajectory equations with six degrees of freedom to simulate reentry vehicle or body asymmetrical aerodynamic forces and asymmetrical static and dynamic derivative influences on abnormalities in the rolls and turns of bodies or vehicles. It illucidates the mechanisms which produce asymmetrical aerodynamic forces and asymmetrical static and dynamic derivatives. This article makes use of approximate calculations set up by the author and numerical value calculation methods. It calculates classical asymmetrical aerodynamic forces for reentry bodies. It does qualitative analyses of the patterns or rules associated with aerodynamic forces as they follow changes in the geometrical parameters of vehicles or bodies, having important reference value for the design of reentry bodies or vehicles.
