Basics_2 : Fastest Aircraft


The SR-71 Blackbird

Imagine flying from New York to London in less than 2 hours !

Designed about 30 years ago, Lockheed's airplane is the fastest jet fueled manned vehicle. The SR-71 is powered by Pratt and Whitney's J-58 turbojets. Each turbojet has an after burner and produces a thrust of 32,500 pounds.

The SR-71 can have up to a speed of 3.2 Machs (more than three times the speed of sound), and can fly at altitudes over 85,000 ft ( 25,908m).

In order to resist the heat produced by friction at such speeds, the Blackbird is made out of Titanium (frame), and is coated with a special heat-emitting black paint (hence the name Blackbird) which helps cool the aircraft.

NASA has been doing some research on the SR-71 for more information, follow the link (NASA) and check out the modification like the SR-17 LASRE or sonic boom recordings. We might also look at the Scramjet-powered X-43A, designed to fly at speeds up to Mach 10. Also look at the blackbird's pictures.

I guess we don't know if there an aircraft faster than this right, until the right occasion shows up.
One never knows what the U.S. or the Russian governments can come up with.
