After Chen Fei saw the gesture of the staff outside, he let out a breath, then raised his foot and released the brake. The moment he released the brake, the wheel block plate quickly retracted downwards. The two actions were coordinated.
It's perfect, it just means there is some program controlling it.
The J-15 began to slide forward.
At the beginning, the speed was not very fast, but as the power of the engine was gradually transmitted, the fighter's taxiing speed gradually became faster.
The runway is only 107 meters.
This is completely incomparable with the Air Force's take-off distance of 700 to 800 meters on land.
When Chen Fei drove the Zhefei Shark for eighty meters, the speed was still not enough to meet the minimum requirements for takeoff. Therefore, at this time, he could only rely on sliding across the deck.
The 15-degree ski-jump deck helped the fighter to lift its nose during the last 20 to 30 meters of taxiing. The fighter was able to obtain enough lift in advance. The fighter slid over the rocker and jumped into the air on three legs, climbing slowly and staggeringly.
This job seems simple, but in fact it is extremely scary.
14° elevation angle, ski jump takeoff, what everyone usually sees is a beautiful arc. But for carrier-based aircraft pilots, every time they take off on the deck, due to the short taxiing distance, they need to quickly add the aircraft to takeoff
The speed. Instantly accelerating, the take-off deck that the pilots saw was not a 14° slope at all, but a huge steel wall rushing toward them. The moment they taxied at high speed, they felt like they were accelerating and hitting the wall.
This situation is a great challenge for the pilot and a great test of the pilot's psychological quality. At the same time, this action also places extremely high demands on the pilot's body.
boom--
The fighter jet rushed onto the skid deck and took off into the sky.
Chen Fei's heart suddenly felt empty, as if his feet were empty, but he quickly adjusted.
To be honest, he had already mentally anticipated this action of hitting the wall, but when he actually faced it, he still felt very nervous.
The plane soared into the sky, and the flight tower control center took over command.
Soon, Dai Ming's voice came: "Yao Dong Yao, keep going, your current condition is very good, pay attention to the speed, report when you arrive, over!"
"Yao Dong Yao understands!"
There are actually several aircraft in the base, but Dai Ming allocated this aircraft numbered 101 to Chen Fei for use.
This matter may seem inconspicuous, but it also contains some of Dai Ming's little thoughts.
However, Chen Fei did not refuse.
If Dai Ming thinks so highly of him, then he should repay Dai Ming twice as much.
boom--
The fighter plane flew into the air. Chen Fei looked at the airspeed indicator, but the speed had not yet reached the standard. The fighter plane could fly very slowly at a speed of more than 100 kilometers per hour in the air. That was because of the altitude and inertial lift. But if it was in
Such a speed during the take-off phase is completely insufficient to support the normal flight of the fighter aircraft. Therefore, it is very dangerous at this time. Once stalled, the aircraft is in danger of crashing, and an accident may occur within two to three seconds. However, the J-15 is not suitable for this
The problem has been specially optimized. At the same speed, the J-15 can obtain lift more easily than other aircraft, and it can obtain more lift.
Chen Fei waited patiently until the speed exceeded 300 kilometers per hour, and then he started to make steering maneuvers. Although he was very skilled and experienced, he was still very careful during the first practical operation.
The flying shark takes off on the roadbed runway. As long as the speed exceeds two hundred and forty, it can pull up. This number is summarized by Dai Ming and others through practice time and time again. It is very safe, and this number has also been passed by Li Jing and others.
The theoretical calculation of
It's worth it, there's no doubt about it.
However, if you really get on an aircraft carrier, it will be very dangerous to take off for the first time, because there is a very big difference between a real aircraft carrier and a land-based runway. This difference can even be fatal, that is, the land-based simulated flight deck does not move.
, and the real aircraft carrier itself has speed, and the real aircraft carrier deck will not be as stable as a land-based runway, but will sway around. If the wind is stronger, the turbulence will be more serious. This is a small
Small changes will add countless variables and risks to the flight.
Of course, the research team of Li Jing and others also did some research and devised some solutions. For example, when releasing fighter jets, the aircraft carrier will sail against the wind at full speed. Calculated based on the maximum speed of 27 knots, the speed of the aircraft carrier itself
It is about fifty kilometers per hour, that is, even if the J-15 does not move, it itself has a speed of fifty kilometers per hour. The speed of the aircraft taking off is the speed of the fighter relative to the air flow, so this fifty kilometers per hour is the speed of the fighter.
In other words, the take-off speed of the J-15 carrier-based fighter jet taking off from the aircraft carrier should be the sailing speed of the aircraft carrier plus the speed of the fighter jet, which is calculated from 50 kilometers per hour.
In other words, as long as the fighter plane reaches a speed of 200 kilometers per hour when taxiing away from the ship, it can take off smoothly, and the headwind is conducive to takeoff.
Of course, these are ideal conditions.
In actual training and operations, we definitely cannot follow the ideal situation. Therefore, the runway in the base is 107 meters, because the runway on the aircraft carrier is also 107 meters. The heavy-load takeoff runway in the aircraft carrier is 197 meters, and it is also 197 meters in the base.
The reason for this is that the base has always used the strictest standards to require students. If the students can successfully take off without any external help, then once they arrive on the aircraft carrier, they will have the speed of the aircraft carrier and the wind from the outside.
, then taking off will be easier.
Chen Fei's takeoff just now was quite smooth. There was no headwind or tailwind. It was very smooth.
Wind is not necessarily a good thing when taking off. Headwind is certainly a good thing. However, if there is a sudden crosswind or cyclone, it will be very dangerous. If you are not careful, the aircraft may be destroyed and you may be killed.
Fortunately, Chen Fei went very smoothly this time.
He took a look at the airspeed indicator and other data. They were all good. The aircraft was in very good condition. His first takeoff was a success.
At this time, Dai Ming's voice also came from the radio: "Yao Dong Yao, your posture is good, keep it up. Although it is your first time to take off today, you did a very good job, better than many experienced pilots. Not bad.
Keep it up!”
After hearing this, Chen Fei was in a good mood. He smiled and said, "Yao Dong Yao received it, Yao Dong Yao will definitely continue to work hard."
