WP1: Requirements and Concepts
The requirements and concepts were defined, as well as the overall system boundaries and the interfaces. The candidate suppression agents were pre-selected and characterised and also a risk and opportunity analysis were completed by RISE.
WP2: System Design
The design and the specification of the system, the sub-systems, the components and their interfaces, taking into account the boundary conditions formulated under WP1, were obtained.
WP3: Demonstrator Development
During WP3, detailed demonstrator design with consideration to RTCA-D0160 took place. In this context, the fire suppression test rig was built in accordance with FAA's Minimum Performance Tests.
WP4: System Design
During WP4, and based upon the work performed by RISE, which identified nitrogen as the most suitable agent for use in the EFFICIENT project, test work was carried out for nitrogen using suitable experimental cup burner and explosion vessel rigs developed at LSBU.
Hence, the LSBU test work was able to determine the required extinguishing agent concentration (T4.1) and verify the fire suppression capability of the concept in an explosion vessel by determining that there were no adverse effects of the suppression agent upon the rate of explosion overpressure rise. Thus, it was established that nitrogen represented a suitable suppression agent to use in the main EFFICIENT fire suppression test work program.
Based on the studies of RISE and LSBU, Cranfield designed and developed the cargo compartment simulator, where the 4 test scenarios described in the MPS, were carried out.
WP5: Project Management
The Proof of signature of Implementation Agreement and Consortium Agreement, among the EFFICIENT consortium which is constituted by the Institutes: Cranfield University – Coordinator (CU), London South Bank University (LSBU) and Research Institutes of Sweden (RISE) was accomplished.
A dedicated communication plan was prepared and achieved:
- A common project graphical identity was developed (logo, standardised templates, etc.) and implemented throughout the project.
- A public website was created, with dedicated sections targeting the different audiences described above.
- Three Workshops were organised in which guests with relevant expertise were invited to provide their knowledge and discuss about various issues encountered during the project tasks. Guests with relevant expertise were invited to provide their knowledge and discuss about various issues encountered during the project tasks. They were open to public workshops so that external guests with interest in aviation fire safety could join. They were also very useful to Academics and Research students working within the fire safety field.
- A 5th workshop along with the project final review and closure meeting was planned at Fraunhofer institute to conclude the project. However due to Covid-19 restrictions this could not be held and the consortium had to resort to an online meeting.
- Five article publications were achieved in relevant scientific journals
- Two conference presentations took place, including Ninth Triennial International Aircraft Fire and Cabin Safety Research Conference
- A dedicated article has been published on the Community Research and Development Information Service (CORDIS)
- There were a few more presentations organised, where the work of the EFFICIENT project was presented to the FAA and other relavant organisations
