Brackets are small elements used as local links between aircraft structure, systems and cabin. Nowadays, most of the components of the structure are made of polymer composites, the majority of them being formed of carbon fibres reinforced thermosetting matrices. The state-of-the-art techniques for joining brackets or other small functional elements to these composite structural components are based on mechanical fastening and adhesive bonding. These joining processes are time consuming, and add significant labour and tooling costs to the

Bracketweld project has been running for already two years time (see link). During this period CIDAUT has developed a methodology to adjust the welding parameters, and a methodology to evaluate the performance of the welded brackets. In this process, different surface media have been evaluated selecting the most appropriate one based on different criteria.

CIDAUT has recently started the project BRACKETWELD, a 3 years Research & Innovation Action launched under the Platform 2 of the Large Passenger Aircraft IADP program within Clean Sky 2, which is orientated to the development, assessment and selection of integrative concepts to optimize assembly of elementary parts, sub-components and modules in modern aircrafts. The general objective of the BRACKETWELD project is to contribute to the cost-efficient integration of system and aircraft structures by the development of innovative technology for the rapid assembly of thermoplastic brackets to thermosetting composite components like stringers and frames.
Brackets are small

The project has been focused on the development and optimization of hybrid joints between metal and composite hybrid parts in order to obtain enhanced automotive components with integrated functions. The joints are obtained thanks to the application of electromagnetic forces. This technology allows joining composite materials

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)

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.

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.

Within the scope of the Cleansky Programme, CIDAUT leads a research project aimed at the manufacturing of composite rotorcraft blades with very tight tolerances that will incorporate an Active Gurney Flap mechanism. Active Gurney Flap (AGF) systems enable the rotorcraft to safely operate with reduced tip speeds whilst preserving high performances with reduced fuel consumption and noise; something that constitutes one of the most challenging research areas leaded by the Green Rotorcraft Consortium in the Cleansky Programme: the development of Active Rotor Technologies.
