SR-71 Blackbird
The SR-71 Black Bird is a Mach 3, long rage reconnaissance aircraft. The SR-71 was designed by Clarence "Kelly" Johnson, and since 1976 has held the record for the fastest air breathing manned air craft. Ask your questions about the SR-71 Black Bird here.

Retractable wheels on aircraft are often called "landing gear", and some of the engine designs used in aircraft can contain a gear box. But gears as they look like in cars aren't used in aircraft.
Does nasa still use the sr-71 blackbird?
No it does not. The last flight of any SR-71 was in 1999 and that was a NASA Blackbird. NASA had used Blackbirds as far back as 1969 in collaboration with the USAF, 2 of those 3 Blackbirds being the YF-12.... sister to the SR-71.
When was the Blackbird stealth jet invented?
The Blackbird was not stealth! The concept of stealth did not exist at the time it was designed and built.
Initial work on it began in the spring of 1958 at the request of the CIA as a replacement (A-12) for the earlier, very slow U-2. The first test flight was in April 1962 from Area 51 in Nevada. It went into actual use in 1966.

The original concept was for the A-12 reconnaissance aircraft for the CIA (Project Oxcart), for which design began in the late 1950s. The USAF was seeking a Mach 3+ interceptor and ordered 3 AF-12 variants in 1960. The designation was the YF-12A.
The A-12 first flew on April 26, 1962.
The YF-12A (crew of two) first flew on August 7, 1963.
When the F-12 program was scaled back, the longer variant of the A-12 was proposed as a strategic bomber, the B-71. 32 of these aircraft were built as RS-71 twin-crew reconnaissance aircraft, with the designation soon changed to SR-71. The SR-71 first flew on December 22, 1964. Production ceased in 1968.
Want a Good Biology working model for school exhibition .URGENTLY..?
plz send me a good working model of biology,its really very urgent...
How is the SR-71 blackbird important in aviation history?
At the time satellites have not became a major impact and the highlight of the Blackbirds carrer was during the Cuban Missile Crisis, of which it could be deployed to take updated pictures in a matter of hours. Its top speed of Mach 3 enables it to outrun any ground-to-air defenses and any aircraft that tried to intercept it
Where is Lockheed Martin Located?
Lockheed Martin is located in California, Houston Texas, New Jersey, Pennsylvania and in Virginia. Lockheed Martin is located in the United States of America.
What is the slowest speed the SR-71 can go?
The stall speed of an SR-71 is 150 knots. All that really means is the airplane will fall out of the sky if you slow down to 150 knots.
"Minimum aerodynamic control speed"--how fast you've got to go if you want to steer the airplane--is more important. An SR-71 with full fuel tanks has a minimum aerodynamic control speed close to 300 knots--which is one of the reasons you never took off with full fuel tanks. The less the plane weighs the lower this speed is, so they'd put 45,000 pounds of fuel in it (the minimum you could leave with), go up, accelerate to 400 knots or so, refuel and leave.
So, in reality, the slowest speed an SR-71 could go, if you wanted to use the airplane again, was 300 knots.
Who created the SR-71 Blackbird?
The Lockheed company developed the Blackbird as the YF-12 fighter plane in 1964.
What color was the first SR-71?
In practice flights it was unpainted but the flat black paint actually flies 75 degrees Fahrenheit cooler than an unpainted airframe and also the black paint has some radar absorbing qualities.
Who was Lockheed inspired by to create the SR-71?
Back during the cold war a plane was shot down over the Soviet Union while exicuting a recon mission. The United States set out on what is know as a "black project" for the purpose of accomplishing one task: to build a plane that could fly so fast it was virtually impossible to shoot down. The ending result: the SR-71 "Blackbird". The plane could out run missles and flew so high bullets couldn't reach it. Ontop of that, the planes stealth design gave it a minimal radar cross section, helping aviod it getting shot at in the first place. An SR-71 has never been lost in combat, and the only damage one has ever taken was when it was flying low and a bullet intended for another plane grazed it's wing.
How fast did the SR-71 Blackbird airplane fly?
SR71 Blackbird Model M-21: maximum speed: 2211miles/h Generally, the given answer for all models of the SR71 is: "In excess of Mach 3", or more than three times the speed of sound. see related links below for more info
How much money do you need to rent a SR-71 Blackbird?
You can not rent a SR-71 Blackbird. It is one of the most classified aerial vehicles ever. It was developed by Lockheed's Skunk Works.
How long would it take the SR-71 Blackbird to travel across the world?
To calculate how long it would take for an object to travel a certain distance we need to know 2 things:
1: The velocity (speed) of the object, in this case an SR-71 Blackbird traveling at 3,540 kilometers per hour.
2: The distance the object has to travel, in this case the circumference of Earth which is around 40,000 kilometers.
So now that we know that, we put those numbers in a formula to calculate the time needed for the SR-71 to make this insane journey:
(Time = distance ÷ speed ~ distance ÷ speed = Time)
40,000km (distance) ÷ 3,540kmph (speed) = 11.30 hours = 11 hours and 18 minutes.
Theoretically, an SR-71 traveling at its maximum speed of Mach 3.3 (3,540 kilometers per hour/2,200 miles per hour) in a straight line while maintaining the same heading would need about 11 hours and 18 minutes to make a full circle around the world.
However, in the real world, it's more complicated because of things like fuel usage, atmospheric conditions, it's thrust-to-weight ratio increasing every second fuel is burnt and even the shape and size of the earth changing by every passing second.
Also, running 2 Pratt & Whitney J58-1 turbojet/ramjet engines at maximum thrust for almost 12 hours is practically impossible without encountering a fatal malfunction and let's not even talk about what kind of stress and temperatures it's titanium skin will be exposed to at such a long duration high-supersonic flight.
Sr71 around the world in how many minutes?
Consider the plane's top speed as 3600kmph. The earth's diameter is 12000 km. With refueling time and other things it may be at least 4 hours to go across the world.
How long can a SR-71 blackbird fly at its top speed before it needs refueling?
Around the earth once before it needs refueling.
Is SR-71 Blackbird owned by a private company?
The 32 that were built were owned by the C.I.A. (Central Intelligence Agency) and the United States Air Force.
