Multifunctional lightweight thermal control core for aerospace applications

Important results from the project

** Denna text är maskinöversatt ** The objective of the project was to investigate and develop a new innovative material configuration and design for a multifunctional cooling system of a battery system adapted for use in drones and aircraft. This objective has been achieved through cross-disciplinary collaboration between the project parties. It could be demonstrated in numerical simulations that the material and design of the cooling system meet both the mechanical and thermal requirements. A complete prototype for full-scale testing will be developed in a follow-up project.

Expected long term effects

In the project, a new material design was developed based on Lameras Hybrix material that allows flow of a cooling medium and has a load-bearing function. In the project´s case, air was chosen as the cooling medium to keep the weight of the drone as low as possible. The design was evaluated and optimized through structural and thermal simulations. These analyzes showed that the cooling system could handle even extreme situations without damaging the battery. The material also has good possibilities for series production and upscaling to other aircraft as well.

Approach and implementation

The project was carried out in close cooperation between the project parties. Within the project period, a number of projectand work meetings were held to produce requirements specifications, develop concept ideas and discuss results. Two numerical studies were carried out by RISE with the aim of optimizing the design and evaluating functionality in different temperature scenarios. As material supplier, Lamera developed a manufacturing method and was also able to manufacture substructures of the cooling system. A full-scale prototype is to be built in a larger follow-up project.
