A Wing Weight Estimation Method Based on Wing-box Beam Design

摘要

In this paper, a wing weight estimation method for transport aircraft is presented. By establishing related computational framework, a wing-box model is developed based on wing-box beam design, from where a wing weight estimation method is derived. The key steps of this work include parametric modeling based on structural model simplification, aerodynamic study, finite element method, and aeroeiastic analysis. The influence of the mounted pylon has been considered for the wing-box sizing. This method has been validated using data of two different transport aircrafts. which shows that this method is robust and efficient. Outcome of this paper could be rapidly integrated in the conceptual design phase.
