The fastest aircraft in the world (23 photos)

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




 
Lockheed SR 71 was in service with the US Air Force from 1964 to 1998. Of the 32 aircraft built, 12 were lost in accidents not related to the actions of the enemy. From 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 call sign of the aircraft - «Blackbird».




In most of the aircraft using the titanium is limited, it is used only in the components subjected 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 the weight, thus increasing the speed.







Flying at an altitude of 24 000 meters are not allowed to use the standard masks, which could not provide enough oxygen above 13, 000 m. Were made special airtight protective helmets, which are also used on space shuttles. Engine Pratt & Whitney J58-P4 was significant innovation of his era - a unique hybrid of issuing 145 kN starting push.



Initially engines Blackbird alternately triggered by additional, start the engine. The operation was very noisy, and ultimately has created a quiet, pneumatic start system.



The first flight of the fastest aircraft in the world has made December 22, 1964, at Air Force Plant 42 in Palmdale, California. SR 71 first entered service in January 1966.



SR 71 was the fastest and most high soaring manned combat aircraft in the world during his career. July 28, 1976 was broken the world record for its class "flight altitude" was 85, 069 feet (25 929 meters). Several planes exceeded this height in the rapid rise, but not on a long flight. On the same day, SR 71 set an absolute speed record - 1 905.81 units (2, 193.2 mph; 3, 529.6 km / h). Lockheed also holds the record for "Speed ​​at the specified rate", it reached from New York to London (5 646 km) in 1 hour 54 minutes and 56.4 seconds, 1 September 1974.
