A Java toolchain of programs for aircraft design

The purpose of this work is to provide a comprehensive overview of JPAD (Java toolchain of Programs for Aircraft Design), a java-based framework conceived as a fast and efficient tool useful as support in the preliminary design phases of an aircraft, and during its optimization process. The software platform is made to perform fast multi-disciplinary analysis of an established aircraft configuration and to search for an optimized configuration in a domain, whose boundaries are defined by the user. The following sections will focus on the description of the software structure and on the results obtained from a case study carried out assuming as baseline a regional turboprop aircraft model similar to ATR-72.
