This work presents a model propeller design for multidisciplinary optimization. The aerodynamic design is a meta-model with X-Foil and empirical data. Reynolds and Mach number, the maximum camber and thickness of the airfoil are inside the meta-model. Blade Element Theory was used with induction velocities from a Lifting Line theory for propeller wake and the roll-up at the tip. Structural model is a unidirectional finite element. Optimization was performed using the simplex method. This model can be applicable for propellers operating at low Reynolds number.
