Technology Description:

Raytheon Technologies Research Center (RTRC) proposes to develop a multi-material and multi-physics topology optimization (TopOpt) design framework to efficiently design novel high temperature (capable of operations up to 800°C) and pressure (up to 25 MPa) heat exchangers (HX) with superior power density and structural durability. The result will increase heat duty for a similar heat exchanger weight and improve durability while remaining cost competitive. The proposed framework combines novel TopOpt methods incorporating multi-physics considerations and additive manufacturing constraints based on the approach selected. The proposed unified, multi-physics conceptual design approach will enable power generation systems for hybrid aviation and ground power systems that can reduce energy consumption by more than one quad per year.
