An analysis is performed to evaluate the viability of an additively manufactured, lattice frame material heat exchanger to be used as a recuperator for a small turboelectric hybrid aircraft. Inconel 625 alloy and silicon carbide are compared as potential candidates for this high temperature application. The model calculates the heat transfer around the struts of the tetrahedral lattice frame by likening this geometry to flow through a tube bundle. A stepping sequence is used to solve for the heat transfer in a representative cross flow heat exchanger and correlations from previous research are used to calculate pressure loss. Using NASA's Numerical Propulsion System Simulation and the Breguet range equation, the impact of the heat exchanger performance is compared to the aircraft baseline. The Inconel 625 alloy heat exchanger showed a 38% increase in the overall range, while the silicon carbide variant increased aircraft range by slightly greater than 47%.
