Pictures and albums about Sr-71 published in entertainment

The Lockheed SR-71 is an advanced, long-range, Mach 3 strategic reconnaissance aircraft developed from the Lockheed YF-12A and A-12 aircraft by the Lockheed Skunk Works. The SR-71 was unofficially named the Blackbird, and called the Habu -snake- by its crews. Maximum speed- Mach 3.2+ --2,200+ mph, 3530+ km/h-- at 80,000 ft ,24,000 meters . This is a fictional image created using screenshots from a computer flight sim.

Before the Sr-71 Blackbird, titanium could only be found in aircraft in high-temperature exhaust fairings and other small parts directly related to supporting, cooling, or shaping high-temperature areas. The decision to build the Blackbird's structure using 85% titanium and 15% composite materials was a first in the airplane industry. The advances made by Lockheed in learning to deal with this material have been used in subsequent high-speed aircraft such as most modern fighters. Studies of the aircrafts titanium skin revealed that the metal was actually growing stronger over time due to the intense heating caused by aerodynamic friction, a process similar to annealing. The Pratt & Whitney J58-P4 engines used in the Blackbird were the only military engines ever designed to operate continuously on afterburner, and actually became more efficient as the aircraft went faster. Each J58 engine could produce 32,500 lbf (145 kN) of static thrust. Conventional jet engines cannot operate continuously on afterburner and lose efficiency as airspeed increases. The J58 was unique in that it was a hybrid jet engine. It could operate as a regular turbojet at low speeds, but at high speeds it became a ramjet. The engine can be thought of as a turbojet engine inside a ramjet engine. At lower speeds, the turbojet provided most of the compression and most of the energy from fuel combustion. At higher speeds, the turbojet throttled back and just sat in the middle of the engine as air bypassed around it, having been compressed by the shock cones and only burning fuel in the afterburner.
