Abstract
This study deals with an alternative supersonic fin-stabilized projectiles steering method using mechanical flow control by means of micro-actuators. To understand the physical phenomena that occur by employing such a device and to validate the capability of steady numerical simulations to predict its effect, a fundamental investigation based on PSP and PIV measurements has been performed on a simplified configuration. The conclusions of this study allowed to use CFD calculations for determining the optimal actuator position and calculating the aerodynamic coefficients which are required to perform 6-degrees of freedom trajectory simulations so that the potential deviation of the projectile could be estimated. Finally all these results have been validated by means of open range firings at the ISL testing site.
