A few more facts:  this airplane was called a wet wing. It did not have fuel bladders. The wiring was fed through the fuel tanks.

Here are some fun facts about the SR 71 and a question: where is the doghouse?

The SR-71 was the first aircraft to use its own fuel for hydraulic fluid. It was called the fuel hydraulic system.

An engine-driven pump provided 1800 psi of recirculating fuel to accurate various engine components and then returned it to the aircraft fuel system to be burned. Fuel was used in the actuators to control the afterburner nozzles, which maintain the proper exhaust gas temperature and control the thrust output. The fuel was also used in the engine actuators to shift the two-position inlet guide vanes from their axial position to the cambered position and back again. This was just another of the many first-ever inventions of the SR-71.

The J58 engine was hydromechanically controlled and burned a special low-volatility jet fuel mixture known as JP-7.

Emergency fuels could be used in the SR-71 if the crew was low on fuel and had to use ANY tanker (as already explained, the Blackbird relied on KC-135Q tankers [that could simultaneously carry a maximum of 74,490lb of JP-7 and 110,000lb of JP-4 for their engines]. Still, the SR-71 could also be refueled by standard Stratotankers in the event KC-135Qs were not available or if the Blackbird crew had to deal with an emergency) they could find to avoid the loss of the aircraft. The emergency fuels were JP-4 or JP-5, but they limited the Blackbird's top speed to Mach 1.5. There were six main fuselage tanks. All 80,285 pounds of JP-7 fuel were carried in six main fuselage tanks.

The tanks numbered one through six moved forward to aft (back) tank 6B. It could hold 7,020 pounds of gravity-fed fuel and two tank sumps.

This was also called the “doghouse” and was located in the extreme back portion of the fuselage.

These are just a few interesting facts I found by reading Rich Graham’s “SR 71 Revealed the Inside Story.

Inspired by a childhood dream to fly, she pursued aviation despite gender barriers, saying, “I saw no reason why I couldn’t do what I loved.”

Before women could enter combat roles, Shults taught Out of Control Flight and acted as a bogey/bandit, challenging Top Gun students, squadrons, and carrier groups in simulated combat.

After her Navy service, she flew over forest fires one summer before joining Southwest Airlines. On April 17, 2018, Shults’ skill shone when she safely landed Southwest Flight 1380 in Philadelphia after an engine explosion at 32,000 feet caused rapid depressurization and system failures. Her calm expertise saved all 148 passengers and crew.

Fan – The large front fan draws in massive air, most of which bypasses the core for thrust and quiet operation.

Compressor – Increases air pressure before combustion using multiple rotating and stationary blades.

Combustion Chamber – Injects and ignites fuel, mixing it with compressed air to create high-energy gas.

Turbine – Extracts energy from the hot gases to power the compressor and fan.

Exhaust Nozzle – Accelerates remaining gases to produce additional thrust.

Bypass Duct – Bypassed air flows around the core, increasing thrust and efficiency.

Used in most modern airliners for fuel efficiency, quieter operation, and high thrust.
