In the SR-71 the temperature change from -55° (35,000 feet.) to over 500 degrees at Mach 3 caused the aircraft to expand up to 13 inches. You can see a corrugation in this picture. How do you run cables and piping from the front to the back? Through the fuel tanks. The fuel system was our heat sink. We always wanted the tankers to have cool fuel, 60° or lower for two reasons 1. we can get more cold fuel into the tanks. 2. For our heat sink.
