An electrical power generation system incorporates thermoelectric devices (TE Devices) for electrical power generation adjacent a flow path heat exchanger (HEX) adjacent to a vehicle flowpath structure such as a scramjet flow path to take advantage of the waste heat, high thermal gradients, and available, unused volume. A thermally conductive material communicates thermal energy from a vehicle external skin structure to the TE Device while a thermally conductive compliant material allows the TE Device to 'float' with minimal mechanical stress.

Flowpath heat exchanger for thermal management and power generation within a hypersonic vehicle

The present invention relates to a scram jet engine for use with a hypersonic vehicle. The scram jet engine has an upper boundary wall, a lower boundary wall, and a plurality of side walls defining an inner air flowpath. The walls are formed by a plurality of tubular heat exchanger panels. Each of the heat exchanger panels comprises a plurality of structural panels, each having a plurality of cooling passages, joined together. In the scram jet engine of the present invention, fuel may be used as a coolant and supplied to the cooling passage.
