An aircraft design workflow using the automatic knowledge-based modelling tool JPAD Modeller

This paper describes the integrated workflow implemented inside the knowledge-based design tool JPAD Modeller to couple aircraft modelling and aerodynamic analyses using the software FlightStream®. This work aims at showing how to enable aircraft designers to speed up design tasks related both to the modelling and to the aerodynamic assessment of a complete aircraft by providing fast and reliable feedbacks starting from the conceptual and preliminary design phase. A case study concerning the generation, the modification and the aerodynamic analysis of a turboprop commuter aircraft will be shown, also reporting the amount of time required to complete the workflow as well as providing some details on the level of accuracy of the aerodynamic solver used for this type of applications.
