Multi-disciplinary analysis and optimization Java tool for aircraft design

The first stages of the aircraft design process require to carry out multi-disciplinary analyses as fast as possible, and with a certain grade of accuracy. During the conceptual and the preliminary phases, the goal is to search for the design that best fulfils the requirements. This work presents a Java framework, named JPAD, developed at the University of Naples Federico II by the Design of Aircraft and Flight technologies research group (DAF) to perform multi-disciplinary analysis and optimization of transport aircraft. This paper describes all the JPAD capabilities, focusing on the sensitivity analyses and optimization modules. At the end, a case study concerning the optimization of a regional turboprop aircraft model similar to the well-known ATR72 will be presented.
