Ramjet

Inside of the Ramjet of the SR-71. The P&W J-58 could endure sustained speeds of Mach 3.2. The temperature limitations of the skin of the SR-71 was actually what restricted how fast the aircraft could travel.

It's called the Blackbird because black skin color maximized the radiative heat transfer of the aircraft.
