Chapter 861: Cutting the canopy

Chen Rui took the fire hose and continuously sprayed fire water towards the trainer plane. If the plane exploded, he would definitely be affected.
But at this time, he didn't think much about it. In his eyes, the plane accident was quite terrible. The plane was sitting in the plane with his own counterpart. Although the two quarreled, it was just a small contradiction. And now, it is a matter of life and death.
While spraying water, he shouted loudly: "Open the canopy and leave quickly!"
What happened to this pilot, didn't he even open the cockpit to escape? Waiting for the plane to explode, what can I do?
Kaili stopped her efforts. She looked outside helplessly, watching Chen Rui holding the fire faucet and spraying water towards her plane. The flames behind had disappeared and turned into black smoke. The sun shone on Chen Rui, showing him The figure is exceptionally tall.
At this moment, Kelly was a little moved.
As a pilot, she is arrogant, even in the Red Arrows aerobatic team, she is also arrogant, she believes that one day, she will become the pride of the entire Red Arrows, and even become the captain, she is the best Royal Air Force pilot .
She has never put anyone in her eyes, but now, this young man from Han country looks so exciting.
At this time, the fire engine and the ambulance had already arrived. The fire engine started to spray foam to dilute the leaked fuel to prevent another fire. The ground-based refueling truck risked danger and started to unload the fuel. Kelly still had no owner in the cockpit. Waved. At this time, Chen Rui didn't need to do anything anymore. He watched Kaili sitting there and knew what had happened. The cockpit lid was locked.
This situation is not very common, but once it occurs, it is quite a speechless situation.
Because the high-altitude air is thin, once the cockpit canopy is unlocked, the pilot is immediately exposed to low pressure in the air and may lose consciousness instantly. Therefore, the cockpit canopy must have a complicated locking device. Once this device fails, it will be very troublesome.
The inside of the cockpit is sealed. The engine has stopped and oxygen can no longer be supplied. After a long time, the pilot inside will be suffocated.
Several ground crews were discussing the plan, but they couldn't tell why.
The sun rises higher and higher, and the hot sun shines into the cabin, and the temperature in the cabin will soon rise.
"Use a cutting machine to cut open the cockpit cover!" Chen Rui shouted to them: "Quick, quick!"
Cutting Machine? Hearing Chen Rui's words, several ground crews were taken aback, and then reacted, yes, go to the cutting machine! The aircraft of the Red Arrow Aerobatic Team suffered a serious failure. Two aircraft accidentally caught fire, and the remaining aircraft could not take off for the show. The show could only be temporarily cancelled and the F-15 fighter jet of the Eagle Country took over.
The other people also came down from the cockpit, looking at the trapped Kelly, and now, Chen Rui has picked up the cutting machine: "I'm here, I am familiar with this."
Chen Rui is still really familiar with it. He has used this method before to rescue a trapped comrade.
He held the hand-held cutting machine and turned it buzzingly. When the grinding wheel approached the canopy, sparks suddenly appeared. He firmly grasped the cutting machine with both hands and watched the cutting gaps grow more and more. Big.
The cockpit cover of a fighter jet has also been developed for a long time. The original open cockpit did not require a cockpit cover, at most it was just a windshield.
Later, with the increase in speed, a fully enclosed cockpit was required, and the most commonly used inorganic glass was used. However, inorganic glass is brittle and fragile and has poor process performance; it is difficult to make complex curved surfaces, and only three pieces can be used. Plane windshields cannot be processed into arc-shaped windshields that are more in line with aerodynamic characteristics and have lower resistance; and the density and weight are large, which is not conducive to the weight reduction of the aircraft.
Subsequently, organic polymer transparent materials with good process performance, light weight and high strength, namely machine glass, gradually became the main force of aviation transparent materials. Acrylic transparent materials were used first.
The advantage of acrylic is high specific strength. Under the same strength, the weight is only 50% of traditional inorganic glass. Therefore, the cockpit cover made of acrylic material is much thinner than the inorganic glass canopy; at the same time, it is resistant to environmental effects. It is also very prominent. After many years of use, its mechanical properties and light transmittance can basically be maintained; in addition, acrylic materials have good light transmittance and can transmit more than 90% of sunlight.
Up to now, almost all the cockpit covers of fighter jets are made of this material, but the biggest disadvantage of this acrylic material is that it has poor impact resistance and temperature resistance. When fighter aircraft take off and land, they are prone to bird collision. The blocking ability of this kind of glass is much worse.
Therefore, polycarbonate materials were later invented to solve these problems. They belong to the cockpit cover materials used by advanced aircraft such as F-22 fighters.
When Chen Rui was cutting, of course he didn’t cut blindly. Instead, he cut along four specific places, where the ejection seat’s rupture gun shot. It’s the easiest and quickest place. In the sparks, the cockpit The lid was cut out with a big opening.
"Thank you." Kaili said, reaching out, Chen Rui took her hand and left the cockpit.
The stretcher of the medical staff on the side was already ready. Seeing Kaili came out, she wanted to go up to meet her and check her body. Kaili waved her hand: "No, I'm fine. Our flight show hasn't started yet."
Looking at Chen Rui again, Kaili strode towards the captain: "Captain, I request the use of a spare machine."
The simple decision made Chen Rui admire very much. This is what the air force of a major country looked like. Even if it had just been involved in an accident, it was almost burned to death in it. After coming out, he still wanted to perform the mission.
This strength is strong enough.
Chen Rui admired it. As for the tenderness contained in the gaze that Kaili had just cast, he didn't realize at all that he only had a career in flying, and he had not considered anything else. He was still young.
Captain Medellin’s face was extremely gloomy:
Our plane is faulty and must be overhauled. I am afraid that we are powerless in this flight show.

"What's the problem?" Kelly asked.
"It may be a problem with the fuel being filled."
Their airplanes are all carefully maintained. If there is a mechanical failure, no one will believe it, so the biggest problem is the fuel problem.
Just check the fuel this time, and you will know the driver of the fuel truck.
"Captain, the driver of the fuel truck, after going to the hospital, had an accident and was not rescued. However, the base personnel confirmed that the driver of the fuel truck was not our staff at all, he was a fake."
