LATECOERE is the world independent leader on the “aircraft doors” market and wants to strengthen this position. ELCOCOS project is the right opportunity to maintain this leadership and to improve the European industry competitiveness as a whole. ELCOCOS consortium is a strong and complementary partnership of leading European industrials and research organizations in the area of aerospace and material development. ELCOCOS is composed of four companies whose expertise will help to develop a composite door using infusion (LRI) technologies as per the aforementioned call: - LATECOERE for the project management, door design and sizing, composite coupons and door tests; - CORIMA TECHNOLOGIES for the composite tooling design and manufacturing; - COMPOSITADOUR for the lay-up; and - INSTITUT DE SOUDURE (ISA) for the Injection process. ELCOCOS objectives are to: - reduce development cost, - decrease the weight of the structure, - improve significantly the recurring cost, and - reduce the industrialization cost. ELCOCOS consortium will fully define technical and cost performances of an optimized infused structure. Predicting the fibre and resin behaviour, correlated with physical specimen, mastering the infusion process through numerical simulation, optimizing the curing cycle thanks to a self-heated composite mould, the final objective of ELCOCOS is to manufacture a full scale demonstrator representative of what could be the next generation of airframe structures comparable to door structures. ELCOCOS is fully in line with the call. The considered technical WPs, tasks and deliverables fit with the call for proposal. A project management WP is also considered. Specific actions are made to ensure dissemination of project results and sustainability of the action. Measurable KPIs and risks are also considered. ELCOCOS consortium is composed of the expected skills, capabilities and certifications expected from the applicants allowing the successful achievement of the project.
