MULTIFUNCTIONAL HEATED AUTOREGULATED PTC RADIANT PANEL

Periodic Reporting for period 1 - RADIANT PANEL (MULTIFUNCTIONAL HEATED AUTOREGULATED PTC RADIANT PANEL)

Reporting period: 2018-11-01 to 2020-04-30

The RADIANT Project has for ambition to create the smartest self-limiting heating system integrated on cabin panel to revolutionize the thermal comfort of Aircraft while contributing to the competitiveness of our industry. The consortium members are HUTCHINSON, a world leader for Cabin solutions, CANOE is a R&T centre with more than 5 years of expertise in the field of cost-effective carbon fibrous materials and smart composites especially for aeronautics market and CTAG a non-profit technology Center with years of expertise in the numerical simulation for thermal efficiency active in the automotive industry. The RADIANT PANEL project offers a disruptive innovation proposal based on three main pillars:
- A new positive temperature coefficient (PTC) textile coating made of ex-cellulose carbon fiber and a PVDF-based polymer,
- A heated multi-functional cabin panel
- A model and simulation oriented for thermal comfort of passengers

During the project, 2 type of coating will be tested. The textile coating will be assembled with their connectors on the top layer of the cabin panel. It is also proposed to carry out the full cabin temperature and air flow simulation using a specific software (TAITherm) coupled with the Human Thermal Module for the comfort prediction. Functionnal test and certification test will be validated the soltuion.
