In the context of the ever increasing need to enhance engine cooling capability, a new heat exchanger/OGV architecture was defined and evaluated in CS2 framework. The design was validated based on wind tunnel tests carried out at ONERA Modane on two heated configurations. The numerical modelling of those tests confirms the expected thermal performance of the blade, with a very satisfactory agreement between numerical approaches and experimental results. Next steps include the optimization of the internal channel, in order to enhance the energy dissipation process.
