 Obiettivo del progetto (Objective)

'To study the future configuration of commercial aircrafts, it is important to have the most efficient method of preliminary design supported by the most complete database with information on existing assets and validated results. Such combination will set CleanSKY GRA with the right starting point for a preliminary design process that will yield a future advanced technology aircraft. The AERODESIGN project will generate a multi-segment and multi-level technical framework, aimed at creating an entire preliminary design methodology solution providing a realistic preliminary aircraft model based in a data base with existing aircraft data. The main objective of the AERODESIGN project is to find an integrated process of optimization for the design. AERODESIGN divides the preliminary design methodology scope into eight different modules: geometrical, aerodynamic, engine data, weight and balance, mission and low speed performance, costs analysis, engine emissions and noise analysis, each of them being integrated by various technologies that are fused together. The integration will include the use several technologies that will result in a cost effective solution.'

Introduzione (Teaser)

Optimal configuration of preliminary designs lays the foundation for final aircraft concepts that are ready to take flight. A new preliminary design platform integrates eight different analyses to optimise performance and cost effectiveness early.

Descrizione progetto (Article)

Once a configuration successfully passes the preliminary design review, it goes on to the detailed design phase. Knowledge-based and integrated optimisation of all design considerations at an early stage drives major aircraft project savings and minimised life-cycle costs.

Recognising the critical importance of a strong foundation on which to build eco-friendly aircraft for next-generation configurations, the EU funded the project 'AERODESIGN - Preliminary design methodologies' (AERODESIGN). Its main objective was to deliver a comprehensive modelling tool for the best and most cost-effective preliminary designs.

The tool is supported by a complete database of existing aircraft assets and validated results. Aircraft design is optimised based on the changing shape of the lifting surfaces that are provided as input.

Design begins with the initiator that provides a general aircraft architecture from the aircraft requirements and the database of reference aircraft. From this starting point, the framework continues through eight different modules.

Based on the preliminary configuration, the geometry module determines aircraft layout and generates a computer-aided design geometry file. The weight and balance module then determines the weight distribution of the aircraft and its centre of gravity during loading/unloading and flight with fuel burn. Subsequent modules consider aerodynamics, engine data (including fuel consumption and thrust), mission and low-speed performance, direct and recurring costs analysis, and emissions and noise analyses.

The user can optimise the lifting surfaces according to one of four target parameters: maximum take-off weight, cost, noise or emissions. All are important considerations within the ambitious Clean Sky research initiative to decrease the environmental impact of air travel.

AERODESIGN's preliminary design tool has been validated as a powerful platform for the optimisation of aircraft design configurations at early stages. Holistic consideration of overall performance, including costs at this early stage, will help ensure that the EU delivers an eco-friendly and cost-effective fleet for future air transport.
