Objectives

The overall goal of SAFUEL is to reduce fuel system related accidents and incidents by developing the new generation of safer fuel systems. This new generation will be better at preventing occurence of hazards such as fire, ice or fuel system failure, and also to cope with evolving flight conditions and emerging technologies (Composite A/C, More-Electric A/C and Alternative Fuel).

Consequently, SAFUEL has the following overarching objectives:

  1. Improve water detection in fuel and gain knowledge on icing phenomena in the fuel system
  2. Enhance flammability protection in the fuel tank and improve reliability, robustness and performance of inerting
  3. Remove possible ignition sources from the fuel tank
  4. Verify and validate full compatibility of the results to Composite Aircraft and More-Electric Aircraft requirements, considering the increased exposure to lightning and induced arcing in these new technologies
  5. Verify the compliance of results with Alternative Fuel standards.

New technologies developed within SAFUEL will be tested on a modular fuel tank test bench (left). Optical sensors to measure oxygen levels in fuel tanks, based on fluorescence, will be developed within the SAFUEL project (right).

 

 

Expected Results

All Key results are compatible with Composite A/C, More-Electric A/C and Alternative Fuel:

  • Metal-free water detector in fuel tank
  • Metal-free fuel gauging
  • Metal-free oxygen sensor
  • Phenomena of ice accretion and ice release in fuel circulation understood
  • Design rules for FS robustness against ice formation and release

 

Workplan

- no image description is available -The work is organised in 4 ‘RTD’ WPs, all driven by SAFUEL overall objectives to develop the new generation of safer FS (robust and integrated) which better protect aircraft against hazards (‘Ice’, ‘Fire’ and ‘Failure’). WP2 will develop the water management function, gaining S/T knowledge in ice in FS with associated recommendations for FS design released and developing an optical water in fuel sensor (electrically passive). WP3 will develop the in-tank wire-free dual oxygen/temperature sensor (electrically passive) and the optimised FTIS architectures. WP4 will develop the metal-free gauging (electrically passive). WP5 will provide the High Level Requirements to WP2, WP3 and WP4 and will assess the results against Safety, emerging technologies and technological breakthrough (TRL maturity level and integration level) at system level. Assessment will be performed by independent reviewers.

3 ‘OTHER’ WPs will respectively take care of:

Dissemination (WP6 will notably take care of the Public Forum scheduled at M18 and M36 and will host and maintain the SAFUEL public website to widely disseminate results),
Exploitation (WP7 will host and maintain the SAFUEL Knowledge Register recording ownership and access/use rights to SAFUEL Foreground, verifying the Foreground is protecting to fully support the exploitation plan,
Management and the coordination of the Consortium (WP1).
