Analysis of Steady-State Aerodynamic Performance and Control-Surface Effectiveness of a High-Speed Projectile
Abstract
A methodology is presented to analyze the performance characteristics of a marginally stable projectile with the goal to improve maneuverability while minimizing drag and achieving reasonable control surface/deflection requirements. This approach is illustrated with an example guided projectile and used to analyze the flight dynamics across the intended flight envelope to evaluate the maneuverability/stability properties and the flight-control and actuator system requirements. The maneuverability is assessed through a series of analyses of the trimmed conditions to show the angle of attack and deflection required to achieve optimal lift-to-drag ratio across flight conditions. The longitudinal stability derivative and short-period dynamics are presented to evaluate the stability properties across the flight envelope.
