Periodic Reporting for period 1 - DEFENDER (DEsign, development, manufacture, testing and Flight qualification of nExt geNeration fuel storage system with aDvanced intEgRated gauging and self-sealing capabilities)

Teaser

Summary

The DEFENDER project aims at developing, manufacturing, testing, and qualifying innovative next-generation fuel storage system with innovative features to be integrated into the Next Generation Civil Tiltrotor (NextGenCTR) framed in the Fast Rotorcraft (FRC) Innovative Aircraft Demonstrator Platform (IADP). The first step consists of a specification review and preliminary system design activity and a technological study, both aimed to design the fuel system and assessing the effectiveness of the proposed innovations. The Fuel System architecture will be used to drive the next detail design phase. Starting from the requirements, the specification of the interfaces and the digital mock-up, the DEFENDER consortium will proceed with the design (at mechanical, electric discharge, electronic and hydraulic level) and analysis, by minimizing the weight and maximizing the safety. Special care will be dedicated to the advancement â€œbeyond the state of artâ€ even during the early stage of the design.

Work performed

The actions performed during the first period are related to the definition of the project requirements and the trade-off analyses between different innovative configurations. Such activities have been detailed into the documentation for the Preliminary Design Review. Besides the material selection for the tanks, analyses have been performed to assess innovative technologies, especially the application of the Additive Layer Manufacturing technique for the production of metallic interfaces and connections. The first results revealed that the ALM technique may be an effective procedure to optmize the metallic parts of the FSS.

Final results

The potential impacts until the end of the project are:
- significant weight reduction of the subsystem;
- reduction of the manufacturing and maintenance cost;
- reduction of the lead-time with advanced manufacturing techniques;
- safety improvements.
