Abstract : To model today's complex systems requires the ability to combine multiple physical phenomena. The objective of this report is to model the actuation of a canard that could be used to control a projectile. To include the fluid solid interaction, a finite element model of the canard has been interfaced with the computational fluid dynamics code, which models the fluid flow. The canard is actuated by a piezoelectric beam that bends as voltage is applied. The voltage is controlled by a software subroutine that measures the angle of the canard and uses the value of that angle to calculate a new voltage. The combined fluid solid interaction was successfully combined with electrical control to fully model the actuation of a canard in a fluid flow.
