The Project addresses the manufacturing of 2 full shipsets of pax and cargo floor grids for regional Aircraft Fuselage barrel on .ground demostrators using thermoplastic resin reinforced with carbon fiber.The use of manufacturing technologies with a lot of potential for automation will be explored (i.e. Progressive Roll Forming and Induction welding) in order to be competitive in terms of weight saving and recurring cost reduction.

DEWTECOMP project proposal objective will be To develop an induction welding system to achieve innovative and efficient way of structural bond of reinforcement parts (gussets, wedges, fittings) to structural frames to obtain a highly integrated Door Surround Structure (DSS), as well as to be able to weld assembly clips on stiffened panel.In order to achieve the main foreseen objective and system characteristics DEWTECOMP project will: -Provide at the beginning of the project a comparison of the state-of-the-art welding technologies (i.e. Laser, Induction, Conduction, Resistance and Ultrasonic welding-but not limited to them) with a benchmark of maturity to justify the use of Induction welding CETMA patented technology vs baseline resistance welding. -Propose and manufacture the most suitable and innovative system design for the induction welding technology to be applied for DSS, including supporting tools, automated devices, heating systems, end effectors required to weld DSS frames to DSS fittings and clamping methods to ensure welding surfaces contact. The induction welding system will be based on CETMA patented technology. -Generate process parameters in such a way that delivers the relevant information to Topic Manager but keeps the industrial secret that will be part of the exploitation plan of the consortia. For instance welding parameters (temperatures, speeds, pressures, tolerances…) as well as the tooling list and materials required will be provided to Topic Manager. -Manufacture and test coupons to validate the equipment and tooling. -Delivery of the Prototype System and tooling set for manufacturing to the Topic Manager facilities . -Carry on different manufacturing trials in order to proof the welding system characteristics Support set up in the Topic Manager premises. Follow up of the works performed by the Topic Manager until the end of the manufacture of a demonstrator compliant with typical aeronautical

TRINITI aims at developing and demonstrating concepts and methodologies enabling the realization of an integrated multi-material airborne pressure vessel for longterm storage of nitrogen, in particular a halon-free fire extinguishing system employing water-mist and nitrogen. TRINITI’s tank has been conceived to fulfill technical requirements foreseen by the CfP e.g. very low permeation of gases, mechanical loads according to RTCA Do160 Rec. G, good fire-smoke-toxicity (FST) properties, survival of high temperatures, large temperature gradients, as well as resistance against various chemical media. Demonstration multi-material thermoplastic tanks will be fabricated through a combination of processes such as co-extrusion of thermoplastic materials to form a multi-layer and multifunctional thermoplastic material, followed by In-situ consolidation Laser-Assisted Automated Fiber Placement process. The application of highly performing thermoplastic materials combined with advanced automated and out-of autoclave technologies on the one hand will answer to the need for less consuming and faster manufacturing processes (1 stage process), while on the other hand it will ensure reduced weight of the tank, reduced operational costs as well as reduced fuel consumptions and emissions of an aircraft. TRINITI's linerless tank, thanks to the versatility of the Laser assisted AFP antropomorphic robot and possibility to use a dedicate simulation tool to optimise the design of the vessel, is expected to range not less than 10% lighter than their nearest Type IV tanks. A better weight-to-tank capacity ratio, however, is not the only advantage of the high pressure vessel, in fact a significant manufacturing cost flow reduction is expected mainly because the chain of manufacturing processes will be optimized and number of fabrication stages will be reduced. Consortium will aim to reach at the end of the project TRL 6.

The Regional Aircraft IADP will bring the integration of technologies developed in phase one within the Green Regional Aircraft ITD to a higher level of complexity and maturity via two flying test-beds and three large integrated ground demonstrators. The overall goal of the TOD project is to demonstrate rapid manufacturability and validation of a full scale thermoplastic composite door including its surrounding, sub-structure for regional aircraft fuselage barrel. This will be achieved by a tangible step beyond the current state of the art of several thermoplastic manufacturing technologies, some of which are already implemented in other certified aircraft parts. 3 reputable European partners, with a very well-known track-record in their respectively area of expertise, aim to use their background to address the objectives set out in this project. The proposed approach include: • Optimisation and validation of component manufacturing using thermoforming and, joining processes such as, Induction Welding and Resistive Implant Welding, which will enable light weighting by removal of mechanical fasteners. • Take advantage of technology advancement in industry 4.0 automation and on-line monitoring to support higher production rate with high quality performances ( Zero defect) and roubust control.
