Abstract
In this work, a multidisciplinary optimization technique focused on preliminary design of small remotely piloted aircraft is discussed. The multidisciplinary design optimization (MDO) problem currently in study is composed of three sub problems. In the aircraft design, it is considered a maximum total mass, defined as design requirement, and thus it is searched the minimum power-to-weight ratio that is necessary to comply with a series of performance constraints. Next, the wing spar parameters are optimized, aiming wing weight minimization. The maximum allowable stress at the wing root is the constraint used in the proposed procedure. At the end, tail parameters are optimized, aiming also minimization of mass. The framework is organized in a way that other constraints and objective functions can be easily added to the formulation. It is promising for future developments in automated preliminary design process.
