Driving a fighter jet, constantly maneuvering with large overloads, challenging yourself in red vision and black vision, that is an experience from the whole body, and now, sitting in a black bird and looking at space, that is another visual aspect. Experienced.
The starry sky is so vast, the earth is just an ordinary planet in the universe, and everyone is even more insignificant. This feeling of space is realized at this time.
After entering space, there will be a sense of emptiness and insignificance. The surroundings are so empty, only oneself and the aircraft around, some people will suffer from mental illness, and some people will fall in love with this feeling.
Nathan belongs to the latter.
Now, looking at the outer space and the arc of the edge of the earth, Nathan couldn't help but say, "It's so beautiful!"
Hearing what Nathan said, Graham was relieved. This time I took Nathan to experience the flight, which is to experience the feeling of going into space. If Nathan has a psychological problem, then you can’t let him touch the MiG-25. What should I do if I fell
Then, he heard Nathan continue to speak: "It should be more appropriate to call Bluebird!"
On the ground, the coating of SR-71 is black. This coating is said to have a stealth effect. Moreover, the fuselage has also planned to reduce the radar reflection cross-section. Unfortunately, when the blackbird is flying at high speed, the high-speed friction zone The huge infrared features, sound, and the resulting radar reflections make it completely invisible.
For example, SR-71 is one of the largest targets on its own Federal Aviation Administration’s long-range radar. It can be tracked hundreds of kilometers away. That is to say, every time the Blackbird performs a mission, it is a target for the target country. An insult, clearly knowing that it was on the top of the head, swaggered past, but it just couldn't be intercepted.
At high temperatures, this black coating will also change its color, becoming the blue it is now. Therefore, the black bird has another name, called the blue bird.
Compared to the blackbirds, the pilots prefer to call the bluebirds, and now that Nathan, a layman, also said the word, it made Graham even more agree.
The blue SR-71 looks even more beautiful. From the small cabin, only the edge of the fuselage can be seen, which is also so pleasing. The feeling of flying at the edge of the atmosphere is also quite wonderful!
"Are we turning?" Nathan continued to ask.
"Yes, we made a circle and just returned to the base. Today's experience flight is over." Graham said.
As the aircraft speeds up, the corresponding turning radius will increase. Now, Graham is turning slowly. The radius of this circle is a full fifty kilometers.
In this case, the tilt of the fuselage is very small, and the overload is also very small. However, Nathan, who is sensitive to flying, can actually experience it. This has to be admired by Graham. Some people are born with it. Flying material.
"We entered the Los Angeles airspace." Graham continued: "We need to cut into the public channel."
"No problem." Nathan looked at the knob in front of him and adjusted it a few times. Then, a noisy sound came from the radio. The same is the same, although it is a passenger this time, there is no problem with occasionally helping with small things.
Any country will have dedicated air control, especially when it comes to big cities, there will be a flight control center dedicated to guiding the airspace.
The black bird is not under the control of the flight control center, but the black bird will definitely be displayed on the opponent's radar screen.
Graham's request to switch to a public channel is definitely useful. Generally speaking, the airspace controlled by the other party may be used.
Now, before Graham started calling, there was a voice inside.
"Cessna, please read the ground speed."
"90 knots." The tower's answer was also brief. (1 knot is 1 nautical mile per hour, about 0.5 per second, 1 nautical mile equals 1.852 kilometers)
Ground speed is the speed relative to the ground. Generally speaking, an airplane knows its own speed. This is done with the help of a PTO. It can only know the speed of the relative air. If the air is also flowing, there will be errors.
This is also a problem that has plagued pilots for many years. It is not until the ground speed measurement radar comes out that the ground speed can be accurately known and the error can be corrected, which is very useful for long-range navigation.
However, the Cessna is only a kind of propeller civil aircraft, widely used in the United States, this thing does not need to read the ground speed at all, it must be the pilot to play with the flight control center.
"Double-shot Beechcraft, request to read the ground speed." Then, another voice appeared.
"120 knots."
This twin-engined Beechcraft is also a civil aircraft with propellers, but with twin engines and faster speeds, this guy must be the first to ridicule.
"Dust 52, request to read the ground speed." At this moment, a lazy voice came from the sky, and the sound was mixed with the whistling of the jet engine.
This voice was obviously more proud. Sure enough, a voice came from the radio: "Ground speed 525 knots, dust."
This must be a jet fighter! This guy is also making fun of the guy in front of him, but he doesn't know that he will soon be the target of being teased.
Compared with the speed, who can compare with the Blackbird reconnaissance plane
Graham in front was itchy. Just when he was hesitant to be chic, Nathan at the back had already pressed the intercom: "Flight control center, I'm Baiyang 20, and I asked to read the ground speed, that's it. "
During the entire flight, Nathan didn't speak much, but the headset was intact, so he knew that Graham's code name was Poplar.
Now, Nathan's request was sent over by radio, but, unlike just now, the ground was silent for nearly five seconds: "Bao Yang, my reading here is 1742 knots."
Haha, is it faster than the ground? Let you know what it means to be outside and there are people outside, there is sky outside the sky, and there are planes above the plane!
The radio was completely silent, and the dust 52 who was just about to make fun of the person must be as uncomfortable as eating shit on his face at this time.
After a while, Nathan heard Graham in front of him start calling: "Request for the right to use the airspace at an altitude of 60,000 feet, over."
Sixty thousand feet is about 18,000 meters. This is the ceiling of most fighter jets. Civil aircraft are basically useless, most of which are around 10,000 meters.
Today's flight control center must be very depressed.
"How are you going to climb to that height?"
Many of the long-range radars are two-coordinates, and there is no height display. Therefore, the dispatcher of the flight control center thought it was teased.
So Graham continued to answer: "We are not going to climb to that height. We are going to descend to that height. Over." (End of this chapter)
