Overall view of the turbine exhaust duct and heat exchanger.

The turbine is just visible left of center at the top of this photo. Next is an elbow and bellows, followed by the heat exchanger. Another bellows section feeds into the turbine exhaust port, used to provide roll control to the missile in flight.

Note the tubing which would have been used to carry pressurant into the heat exchanger and then the heated gases out and to the propellant tanks to provide pressurization.
