ACCUBLADE project (CLEAN SKY): CIDAUT contributes to the validation of Active Gurney Flap systems for rotorcraft blades through innovative research on composites process and tooling design

09/18/2015 by cidaut

One of the most challenging areas of research leaded by the Green Rotorcraft Consortium (GRC) within the Clean Sky Program was the development of Active Rotor Technologies as the Active Gurney Flap (AGF) systems, which enable a helicopter to operate with a reduced tip speed of its main rotor whilst preserving the current flight capabilities. The on-going validation of innovative AGF systems by the GRC required the manufacturing and testing in wind tunnel tests of small scale composite model blades before their implementation at full scale. The integration of the AGF systems into the model blades (figure 1)

remart_1

Since April 2013, CIDAUT has been coordinating REMART project, carrying out the technical tasks in collaboration with 3 partners, CIDETEC, ITRB and PBLH and under the direction of AGUSTA WESTLAND as Topic manager.

This project has been developed in the domain of the CLEAN SKY JTI – Green Rotorcraft which has the aim to improve the environmental impact of the components in aeronautic and air transport sectors. Along the project, the REMART consortium has been involved in the optimization of the use of existing recycling technologies, designing an efficient

CLEANSKY: CIDAUT develops an optimized simulation model for the optimization of Liquid Resin Infusion (LRI) processes

05/19/2015 by cidaut

One of the aims of Clean Sky is to develop new technologies for green manufacturing through Integrated Technology Demonstrators (ITDs) within the frame of both Green Regional Aircraft (GRA) and Eco-Design (ED) platforms, with the objective to realize low weight/eco-friendly aircraft components featuring competitive manufacturing costs. To achieve this purpose ALENIA AERMACCHI, (Leader of the GRA ITD and Member of the ED ITD) has conducted several studies and launched initiatives aiming to develop, optimize and industrialize Liquid Resin Infusion (LRI) processes. Executed out of autoclave (without pressure), the required solution shall reduce weight, related environmental impact and reduce life cycle

WASIS: Vibro-acoustic characterisation of the CFRP fuselage section

03/12/2015 by cidaut

As one of the last activities carried out within the WASIS FP7 Project, Cidaut performed the vibro-acoustic characterisation of two components, firstly one test panel and secondly the largest fuselage section (1m diameter prototype). In both cases the study covered low and high frequency ranges. The aim of this activity was to validate FEM/BEM models for low frequency range and SEA models for high frequency.

Advanced Composite Integrated Skin Panel Structural Testing – Results from Clean Sky ACID Project

03/11/2015 by cidaut

Stiffened panels are required in structures which can be obtained by different processes. They can be made by attaching stiffeners to a thin panel or by producing integrally stiffened panels. An innovating manufacturing process based on Liquid Resin Infusion (LRI) can be employed for obtaining integrally stiffened panels. It is based on moulding a dry NCF (Non Crimp Fabric) pre-form of Carbon fibre plies, which is bonded by a one-shot injection process to high stiffness, pre-cured pre-preg T-section stiffeners. This method presents benefits like lower costs in machining and fewer assembly operations.
