The name of this bird Lockheed SR 71 Blackbird. Equipped with a jet engine.
The maximum speed was recorded in 1976, which amounted to 1,905.81 knots (3,529.6 km / h), which is 58.83 kilometers per minute. Even ground-to-air missiles could not catch up with the Lockheed Blackbird, he had only accelerate. Below you will find more information about it, its history and records, which remain to this day.

Lockheed SR 71 was in service with the U.S. Air Force from 1964 to 1998. Of the 32 aircraft built, 12 were lost in accidents not related to enemy action. Since 1976, he held the world record as the fastest plane.
Built aircraft were painted dark blue, almost black to increase the emission of internal heat and act as camouflage against the night sky. Tanned led to the aircraft call sign # 8220, # 8221 Blackbird.;
In most of the aircraft use titanium is limited, it is only used in components exposed to the highest temperatures, such as exhaust and the front edges of the wings. On SR 71 titanium was used for 85% of the structure of the other parts made of composite materials. It is possible to reduce its weight, thereby increasing speed.
Flight at an altitude of 24,000 meters is not allowed to use the standard masks, which could not provide enough oxygen above 13,000 meters were produced specialized protective airtight helmets, which were also used on space shuttles. Engine Pratt # 038; Whitney J58-P4 was a significant innovation of its unique hybrid era, issuing 145 kN start the push.
SR 71 was the fastest and most high soaring manned combat aircraft in the world during his career. July 28, 1976 has been broken the world record for its class: an absolute altitude reached 85.069 feet (25,929 meters). Several aircraft exceeded this altitude in a rapid rise, but not in the long flight. On the same day SR 71 set an absolute speed record of 1,905.81 knots (2,193.2 miles per hour, 3,529.6 km / h). Lockheed also holds the speed record at the specified rate, it reached from New York to London (5,646 miles) in 1 hour 54 minutes and 56.4 seconds, 1 September 1974.
Originally engines Blackbird alternately launched with an optional, start the engine. The operation was very noisy, and eventually created a quieter, pneumatic start system.
The first flight of the fastest plane in the world to accomplish December 22, 1964, at Air Force Plant 42 in Palmdale, California. SR 71 first entered service in January 1966.
