Aerodynamic Effects of a Wing Surface Heat Exchanger

One challenge for the design and analysis of hybrid electric aircraft configurations is an increased demand in rejection excess waste heat. A wing surface heat exchanger concept, which explored as part IMOTHEP project, foresees transferring from propulsive electrical components to aircraft. Here, mainly dissipated transported by forced convection. The present study focuses on impact via wing’s transfer aerodynamic efficiency characteristics. For this purpose, RANS CFD studies 2D airfoils a 3D propeller geometry regional turboprop configuration representative flight conditions (take off, cruise, taxi in) are carried out. each condition, influence defining parameters, such altitude, freestream velocity, angle attack, temperature, thrust explored. It shown that, when increasing temperature compared against deteriorates all conditions. In reference cruise example, lift-to-drag ratio decreases 4%, while average coefficient reduced almost 20% 300 K. Furthermore, slipstream enhances capacity significantly.
