For every additional item that needs electrical power, added battery capacity is needed, and both of those result in added thermal loading, which requires a more robust thermal control system.

Technologies being tested in the program include advanced guidance, navigation and control, thermal protection systems, avionics, high temperature structures and seals, conformal reusable insulation, lightweight electromechanical flight systems, and autonomous orbital flight, reentry and landing.

Under Wood Dana would build three things: drivelines (which transfer power from the transmission to the axles), sealing systems (which reduce oil consumption and emissions) and thermal-management systems (which control temperatures in batteries and other components).
