Description du projet
Une approche intégrée pour concevoir des ailes d’avion à contrôle actif
Le projet FLiPASED, financé par l’UE, entend révolutionner les ailes d’avion en développant et en testant une conception d’aile dite «à contrôle actif». Ce concept de modification de la forme de l’aile peut réduire de 20 % l’impact négatif des rafales sur les performances aérodynamiques et de 10 % la consommation de carburant. Par ailleurs, il peut réduire de 50 % le nombre de modèles distincts utilisés au cours du processus de développement et de certification des avions. Le projet combinera des modèles d’aérodynamique, de conception structurelle, d’aéroélasticité et de conception des commandes au sein d’une seule chaîne d’outils intégrée en vue d’optimiser la conception de l’aile. Les outils seront validés sur une plateforme expérimentale sûre et abordable. Les résultats expérimentaux et les exigences de conception seront rendus publics.
Objectif
Flight Phase Adaptive Aero-Servo-Elastic Aircraft Design Methods (FliPASED) opens a complete new dimension for the integrated aircraft design. Coupling between aeroelasticity, gust response, flight control methods, instrumentation and certification aspects is not exploited in current aircraft design. A common set of models, coupled with joint requirements enable a multidisciplinary-optimized design for the entire aircraft, leading to more optimized overall performance. The concept of exploiting coupling between disciplines will take advantage of tools developed by the partners in former projects. The main objectives of the proposal aim at tightly coupled multi-objective optimization of advanced, active controlled wing designs through the integration of a collaborative design tool chain. More than 10% fuel efficiency improvement, and 20% reduction in peak amplitude of the gust response, as well as a 50% reduction of number of distinct models used during the development and certification process are set as project goals. Through the integration of all discipline tools from aerodynamics, structural design, aeroelastic simulation and control design in one integrated tool chain an active, condition optimized wing design becomes feasible, enabling enhanced performance at lower weight and cost. The project will raise the efficiency of a currently separately existing development toolchains, by advanced multidisciplinary and collaborative capabilities for whole aircraft along its life cycle. It will develop methods and tools for very accurate flexible-mode modelling and flexible aircraft control synthesis, in the context of reliable implementation of the avionics system, taking into consideration the fault detection and reconfiguration. The accuracy of developed tools and methods will be validated on a safe and affordable experimental platform, and results will be shared along with design requirements and standardized interfaces in an open source approach.
