How does a Lockheed SR-71 Blackbird engine work?

Air was initially compressed (and heated) by the inlet spike and subsequent converging duct between the center body and inlet cowl. The shock waves generated slowed the air to subsonic speeds relative to the engine. The air then entered the engine compressor.

Why are the SR-71 engines so far apart?

Because the fuselage works as a lifting body in cruise and has a short angle of attack, the cones also point down. As a result, the location of the engine intakes is confined twice. It must be far enough away from the fuselage to avoid interfering with the fuselage’s disrupted airflow.

Can the SR-71 Supercruise?

Many supersonic military aircraft are not capable of supercruise and can only maintain Mach 1+ flight in short bursts with afterburners. Aircraft such as the SR-71 Blackbird are designed to cruise at supersonic speed with afterburners enabled.

Why does Blackbird leak fuel?

Thanks to its refueling abilities, the Blackbird was able to travel more than 12,000 nautical miles. Though the SR-71 heated up while it took flight, it cooled down while landing. As a result, the panels contracted, causing them to return to their original state. When this happened, the jet’s fuel leaked again.

How does Pratt & Whitney J58 work?

The Pratt & Whitney J58 (company designation JT11D-20) was an American jet engine that powered the Lockheed A-12, and subsequently the YF-12 and the SR-71 aircraft. It was an afterburning turbojet engine with a unique compressor bleed to the afterburner that gave increased thrust at high speeds.

Did the Concorde have afterburners?

Afterburners were essential for getting Concorde through the sound barrier. The enormous consumption of fuel was one of Concorde’s downfalls – as fuel prices rose, profitability fell.

How many gallons is 80000 pounds of jet fuel?

The 80,000 pounds of JP-7, or about 12,000 gallons, needed a flash point high enough to avoid unintended combustion, partly because fuel was used as the primary heat sink to dissipate the high temperature in the airframe.
