Why SR-71 Pilots Counted to 58 to Dodge Missiles

On July 26, 1968, the SR-71 was flying over North Vietnam. The inspection system officer RSO noticed that the R light was on the panel. This meant that North Vietnam's Ground Air Missile Base was searching for Blackbird. RSO wasn't worried. This was a common occurrence. A moment later, he discovered that the M light was on. That meant that Vietnamese radars were tracking them. It was a rare thing. But what happened next was probably the longest one minute for the crew. Blackbird is flying from 83,000 feet above Hanoi to Mahe 3 in the middle of the day. The RSO found an L-light on the electronic response device panel. It meant that more than one missile was fired at the aircraft. The atmosphere inside the cockpit has become tense. The pilot asked the RSO if the L-light had been on for 1 minute. Time was important. Because the SA-2 missile's flight time was 58 seconds. After landing, the camera confirmed that both missiles were fired. This was the first incident against Blackbird. Over the years, more than 4,000 missiles have been launched at Blackbird. Not a single step hit the target. Why would SR-71 need two eyes to start? How could a Blackbird fly at three times the speed of sound without being photographed blurry? What is the design feature that limits the maximum speed of the aircraft? And the reason the SR-71's combat range was limited was that it was liquid nitrogen instead of fuel. It's not what you think. Although Blackbird has never been shot down by the enemy, About a third of the SR-71 fleet was destroyed in a freak accident. Some people have come to believe that Blackbird piloting is a continuous emergency procedure. But the reality was the opposite. She was a pretty reliable machine. Almost always everything worked perfectly. Just in case there was a problem in the airplane, it gave the pilots an unforgettable moment. When there was a problem in flight, the pilots felt it immediately. Because they knew even the little flashes, movements, and shaking of the aircraft. However, if there is a problem, the warning light will be on. To find out what was wrong, the pilot had to look at the panel between the bridges. This panel has about 40 lights that indicate exactly what's wrong. There's this story. On April 9, 1982, Lieutenant Colonel Shelton and Lieutenant Colonel Bill Keller boarded an SR-71 aircraft that had been stored for several years. It's landed at Bill Air Force Base. Everything was fine. At 70,000 feet, the pilots were surprised when the warning lights went on. Because you handled the emergency situation before the alarm light went on. 40 warning panels showed system A flight pressure failure. Luckily, Blackbird had two independent hydraulic systems A and B. One was a procedure for rapid landing after a partial discharge of fuel in the event of a failure. The master warning light re-lighted while the pilot was descending and System B showed a flight pressure failure. The two crew members said, "Oh, fuck!" Because when both hydraulic systems fail, the emergency procedure is to escape immediately. But the aircraft can be controlled to some extent to avoid escape We continued our flight to the B1 air base. When they reached a point 30 miles north of the air base We contacted the control tower and both flight control and hydraulic systems are down. The control tower mimicked the crew's reaction. When the Blackbird crosses the runway threshold The remaining pressure of the hydraulic system was virtually zero. The aircraft was easily manoeuvrable. Nevertheless, it landed safely. Both the A and B system hydraulic chambers are malfunctioning There are only a few cups left of the six gallons of hydraulic fuel. But the crew wasn't always so lucky. When a similar incident occurred on 21 April 1989 The SR-71 crew escaped due to a hydraulic failure. The pilot and RSO were successfully rescued near the Philippines. The aircraft was later adopted by the US Navy. But why was SR-11 there? Blackbird's main operating units were in two places. Japan and Japan's air base DET-1 and This is the British Royal Air Force base DET-4. Each unit was usually deployed with three Blackbirds. The mission that started in Japan was different from the mission that started in England. In fact, both squadrons' weather and flight missions Due to geographical differences, it was completely opposite. DET-1 was stationed in North Korea, Vietnam, and the Eastern Frontier of the USSR. DET-4 was used to monitor the Soviet nuclear submarine fleet in the Barents Sea region. He was active in the western part of the Soviet Union. According to the pilots, the most dangerous mission is It was flying near the Murmansk submarine base in the Barents Sea. The pilots had to slow down into the air when the engine malfunctioned. They feared that it could be an easy target for the Soviet MIG. For this reason all new crew members He had to do his first tour of duty in Japan before he was deployed to England. Of course, becoming a Blackbird pilot was very difficult and the competition was fierce. On average, only 2-3 pilots are selected for the program each year. Physical conditions for participation were considered to be on an equal level with astronauts. But before the actual operation, the pilots spent about 100 hours I had to fly a special variant of the Blackbird. The SR-77-1B is a training modification vehicle with a high pilot's seat for the instructor. It was the fastest classroom in the sky. Pilot who has been qualified to fly an SR-71 during 30 years of service Only 150 of them were trained in one of the two SR-71-Bs. The name is 6세 트리틀 치구 5개 우교 6개 SR-O21B Blackbird has a record of 1,4354 total flights. He has logged more than 3,339 hours of flight time. He flew more than any other SR-71 in history. But what if you could own a piece of that historic plane? This is the bottom. This limited-edition watch looks like the SR-71's mid-engine suction cup. The actual SR-77-1B uses the material of a 6179 caliber bullet. This dial is an aircraft internal engine and a fuel injector. The top dial was inspired by the Blackbird's Backpack Flap. The clock face is reminiscent of the Blackbird pilot's cockpit. Power reserve indicator for high-speed ignition of the Blackbird I'm going to try to simulate the slot machine system. Brushed-up timing and breakdowns reflect the aircraft's performance. The FKM's mid-range shooting band reflects the Blackbird movement's red nose. The lower part is lightweight and comfortable to wear in the hand, while having a strong presence. Use the link in the description to enter the code. Order a timepiece in advance. This is not a simple watch. The story waits. Only 10 of the 29 SR-77A variants were operated as field stations. The remaining 19 units were under repair after Lockheed engineers dismantled the aircraft. Reassembled or saved. But why would he keep some of the planes? I mean, I'm not. The aircraft was periodically put into storage to ensure that all the aircraft were aged at the same time. This method worked well and the average Blackbird's air time at discharge was 2300 hours. The difference between the maximum and minimum flight time was only a few hundred hours. One of the funniest things you can do with an SR-77A It was the border crossing, the line that divides day and night. When flying at 80,000 feet, the boundary line is much clearer than the surface of the sea. Blackbird pilots flying in the light to the state line It's like going into the Black Wall. During one winter's overhead mission in the Arctic, the SR-71 was at high speed for 1 hour. I crossed the state line six times. This means the crew experienced three sunsets and sunsets in 60 minutes. Sometimes I did it twice a day in the morning. Each pilot's tour lasted for about 6 weeks. This happens four to six times a year. It was an SR-71 pilot flying a KC-253BQ from a base in Bijih. The most boring and uncomfortable thing that mankind has ever known is the back door. It means that you had to endure pain. The pilot's travel time depends on where the mission is being carried out. It was between 12 and 24 hours. The alternative was to fly the SR-71 to the airfield and transport it to the deployment area. The SR-71 was used for high-level missions when it returned to the unit after a regular check. Of course, everyone preferred high-level assignments. Not only that, but the pilots are from the BIL Air Force Base. After breakfast, you'll be able to get your number after 7 hours. I had breakfast again at the Japanese Garden Air Base. The SR-71 was a multi-handed aircraft. Each time the crew took about 18 to 20 hours to prepare. This included the task of aviation experts uploading mission information. I had 16 flight attendants checking the plane for several hours. Then four people filled up the fuel for an hour. The crew arrived at the airport 40 minutes before takeoff. Before each flight, make sure the spikes are stretched and shortened within a tenth of an inch of each other. This was important to ensure that the supersonic shock wave formed evenly on both sides of the aircraft. Otherwise, the air could cause disturbance. Each spike moved horizontally up to 26 inches to fix the shock wave. At 80,000 feet, the air is thin and the faster the speed, the more air and fuel the engine needs. At higher speeds, the spikes were reduced and more air was injected. The spike's movement prevented the shock wave from entering the inlet. If the shock wave hits the first compressor blade, it will destroy the engine immediately. Speaking of engines, the Blackbird's J58 engine had no starter. So the AG330 was used to start the truck's VW engine. The original car had two V8 engines in the interior, fitted in a straight line with automatic transmission. This transmission was connected to the Blackbird engine via a vertical drive shaft. To start each engine, you needed a view card and no muffler, so the noise was loud. The limit to flying the SR-71 to the surface was the amount of liquid nitrogen required, not fuel. As fuel was exhausted, the fuel vapor was filled to the top of the tank and could ignite. The fuel tank was heated to 300 degrees Fahrenheit during the flight. On July 17, 1996, a TWA Boeing 747 aircraft took off from New York in 13 minutes. The fuel tank in the central fuel tank exploded. So to prevent the Blackbird explosion, the solution was to remove the fuel vapor and replace it with nitrogen. The heater converted liquid nitrogen into gas and circulated it into the fuel system. However, every time the tank pressure in the air-fuel tank exceeded 6%, nitrogen was emitted from the fuel tank. The problem is that Blackbird has only two 27.5 gallon liquid nitrogen tanks and the plane's range is limited by the amount of liquid nitrogen in the tank. Then 13 gallon additional tanks were installed to increase the cruising range. It's true that the SR-71 Blackbird leaked fuel. It is also true that this aircraft always had a refueling service immediately after takeoff. But it's a misinformation that the air supply is due to a fuel leak. The Blackbird was air-supplied shortly after takeoff for two reasons. The first reason was because of the weight. The aircraft was filled with 80,000 pounds of fuel and the landing gear could be damaged during takeoff and landing. It was a lesson learned at the end of my life. So I refueled after taking off with about half the fuel full. The second reason was for training. In addition to the 29 SR-71As, there were 35 KC-BL35Qs needed for air-to-air training with the Blackbirds. The SR-71 was a spy plane equipped with the most advanced cameras. At 85,000 feet, this camera was able to capture a 6-inch object. But before I took the photo, there were two big problems to solve. The first problem was the cooling of the camera when the plane was flying at maximum speed. When the spy plane flew into the air, for example, the cameras were heated in the middle of the airplane. But the bigger problem was the Blackbird's speed. At cruising speed, the SR-71 was moving at 3,000 feet per second. This is when the camera takes a picture at shutter speed of 1 millisecond. It meant the plane was moving 3 feet during exposure. But in reality the exposure time is much slower. The aircraft moved about 742 feet during slow mode exposure. In the fast exposure setting, it moved 371 feet. This creates a blurred image. The solution was to compensate for the speed of the SR-71 by moving a precision target. How fast was Blackbird? The official declassified answer was that the SR-71 can reach speeds of more than 3mph. The aircraft was designed to target Mach 3.2 but its normal speed was Mach 3.17. Officially the maximum altitude was 85,000 feet, but According to some reports, the Blackbird could fly over 100,000 feet. In fact, the plane could fly faster and higher, but The speed of the compressor was limited to 800 degrees Celsius. This meant that depending on the outside temperature, the blackbird sometimes flew slower or faster. However, in an emergency situation, the crew of the SR-71 could use tactical limits. That is, pushing the aircraft to maximum speed. It was more important to use the aircraft as much as possible than to be shot down by a missile. This meant that the inhalation temperature could reach 840 degrees for up to 1 hour. But I couldn't go over 3.3. Interestingly, the record-breaking flight across the United States The crew originally asked if I could fly the Mazda 3.5. It meant a 60-minute flight from coast to coast. But Lockheed said it was a bad idea. If the engine stops at a speed exceeding Mach 3.3 Because the crew can't keep the front of the plane moving forward. So they flew at Mach 3.3 from coast to coast It took 67 minutes 54 seconds. The only time a Blackbird pilot claimed to have reached 3.49 One wave near Murmansk was when the inhalation temperature was much lower than the 800 degrees Celsius. But the theoretical maximum speed of the Blackbird is Mach 3.5. At that speed, the spike shrinks and is unable to interact with the shock wave.
