Collection description

Performing fast and reliable analyses is a crucial issue during the first phases of Aircraft Design, in particular during the conceptual and preliminary ones. This study aims to be a self-explanatory work as regards the innovative methodologies introduced in the Aerodynamic design of transport aircraft, their integration in a comprehensive java-based tool and the following applications concerning the European IRON (Innovative turbopROp configuratioN) project. Priority identified within the aircraft marketplace are constantly pursuing climate and environmentally friendly goals. Meeting these priorities will have tangible impacts in the aircraft design as a whole, from the implementation of new technologies to the design process itself. Based on these observations, this work is motivated by the following research question: How is it possible to enhance the current state of art of aerodynamic parameters estimation within the aircraft design, coupling aeronautical and software competencies, focusing mainly on an innovative configuration for regional turboprop? This study is collocated in this scenario, offering innovative methodologies that allow to perform preliminary analyses useful in the design process of modern and future aircraft. In this context is collocated the IRON project, whose design process has been followed during the development of this work, which is part of the Clean Sky 2 program for Horizon 2020, aiming at reducing noise and emissions for future aircraft. This work can be divided in four main topics: i) development of a java-based framework for MDAO analyses, focusing on the software structure and on all the aerodynamic aspects, ii) improved methodologies for aerodynamic high lift prediction, iii) validation of developed methodologies, iv ) innovative regional turboprop application. The author had chosen this work organization to best clarify the global scenario in which the research has been conducted, starting from a brief introduction and moving on the computer framework built up for preliminary design, JPAD (Java API for Aircraft Design), completely designed and developed within the DAF (Design of Aircraft and Flight technologies) research group from University of Study of Naples Federico II. Then the improved methodologies are presented developed and integrated within JPAD, coming up beside the semi-empirical methodologies. To come with the reader through the explanation of the work, the following chapter illustrates the methodology validation by means of CFD analyses and wind tunnel test. Finally all the methodologies implemented in JPAD are used to analyse the reference aircraft. Particular emphasis is posed on aircraft aerodynamic, to highlight how the introduced methodology can improve the results leading to better performance output.
