v2 Chapter 47： Fire

A fire in space is definitely one of the last things all astronauts want to encounter.

After the Apollo 1 accident, NASA also redesigned and optimized the interior of the spacecraft, replacing the flammable materials in the cabin with some materials that will automatically extinguish, wrapping the insulation materials on the piping system and wires, correcting wiring problems, and changing The atmospheric pressure in the cabin was changed. The gas in the cabin was changed from pure oxygen to oxygen \ nitrogen mixture. The nylon spacesuit was changed to a spacesuit with a glass fiber coating. At the same time, the training of astronauts in fire handling was also strengthened.

The flame in the spacecraft is very different from the flame of the earth. Without gravity, the hot air generated by the flame combustion in the state of free fall will not rise, but will wrap the flame and form a layer of low oxygen around it. High temperature layer.

Because of lack of oxygen, the flame spreads very slowly, it will become a light ball, and the burning temperature is lower than the earth.

Generally, an alarm will sound in the spacecraft after the fire. Astronauts will then need to wear a breathing mask, determine the ignition point at the fastest speed, and cut off the nearby power source. At the same time, others will use a fire extinguisher to extinguish the fire. Uncontrollable, astronauts need to leave the fire compartment, retreat to other compartments, block the gates, and turn off the air circulation fan of the fire module.

Later Apollo XIII exploded in the service capsule the next day after launch, but the seven astronauts on the spacecraft were in dire danger and responded well, and all of them were safely transferred to the lunar module and the ground. The control center cooperated, abandoned the moon landing plan, drove the spacecraft to the back of the moon, and successfully returned to Earth by using the slingshot effect, creating the greatest miracle in the history of human spaceflight.

Of course, these are the last words.

NASA's fire treatment training is conducted in a closed environment that simulates an aircraft. Of course, no real fire is used. Instead, it is replaced by a red warning light. The participants are required to follow the steps to practice the fire-fighting process, so theoretically there is no Any danger.

According to the order of roll call, this time it was the middle-aged's turn to take the lead. He glanced at the high school students beside him, and the two went into the simulation cabin.

The simulation warehouse has two parts, corresponding to the service cabin and the moon landing cabin, and the two walked straight to the innermost service cabin. This is also where the first part of the training began.

However, when the alarm sounded, they did not remove the breathing masks as required in the manual. The high school students quickly took off their shirts, exposing a drainage bag tied to their bodies.

The water bags were not filled with clear water, but pale yellow gasoline, which was stolen from the storeroom.

He opened the petrol and poured them on the cotton bag that was used to simulate flammables. "You can tell now how we can hide the smell of this thing, lock the door, and then complete the remote ignition." . "

The middle-aged person didn't answer until the high school student poured out all the gasoline, and he quietly backed up to the hatch, while taking out a match and rubbing it, he said again, "I told you my In a single-player competition, I once encountered two players who were small in the real world. In order to compete for the last place, one of them had to kill the other. This is a very difficult choice, very difficult ... "The middle-aged man paused." What I didn't tell you was that I was the one who started. "

"What?" There was an ominous premonition in the high school student's heart. He turned back and saw that the middle-aged person had reached the connection between the service cabin and the lunar cabin.

At the same time, the latter also threw out the match in his hand. The match exactly landed on a bag of cotton bags drenched with gasoline. The fire ignited quickly. The young man has already closed the door of the service cabin.

The simulated fire alarm in the service cabin was still raging, but it sounded ironic against the increasing fire surrounding it.

The high school student used the power of feeding to open the hatch a little bit, but just when he was about to see hope, he was poured into a pot of cold water, and he saw the middle-aged man on the other side from the gap. He took out the lighter and aimed at the lower half of the door.

Like the previous door lock, the heated part melted quickly, but this time the middle-aged person quickly withdrew the lighter. The melted part contacted the ground, cooled down and quickly fixed, connected to the surroundings.

The middle-aged man retracted his hand, but this time the high school student could no longer pull the hatch open.

"Sorry, I didn't tell the truth before. I couldn't hide the smell of gasoline and then complete the remote ignition. I don't have such a prop on my body."

"Are you crazy ?! What good is it to kill me? Are you going to fight with those two alone?" The high school student was sweating profusely, there was gasoline in the water bag, the flame was burning fast, and the fire tongue was ready. He licked his back, and the look on his face became more and more frightened. He even begged middle-aged people to open the door ~ www.novelhall.com ~ But the latter was unmoved. Fighting two people? "The middle-aged man raised his eyebrows." I do have allies, but I'm sorry that that person is not you. By the way, you can call for help out loud, but the two simulation warehouses are closed. Sex is good, people outside can't hear anything inside. "

"Kill me, why do you explain to the people at NASA ?! Do you still want to continue to the moon? Or do you just do it for the sake of others? You are not the kind of person." Flowed out.

The middle-aged man took a few steps back, away from the spreading flames. "Petrol was brought into the simulation cabin. I haven't left other people's vision from getting up in the morning until now until the fire treatment training. Only you are in It disappeared for such a long time after lunch, so everyone will only think that the fire was set by you. As for the reason, I don't know ... Maybe the recent training is too intensive and you may be overstretched, or there may be candidates one after the other The accident caused your stress to exceed the endurance limit. I just went to the lunar module for training in the second part of the evacuation session. When I found out it was too late, and you closed the middle door. "

"Do you think people at NASA will not doubt you?"

"I don't care, as long as there is no absolute evidence, they still need us to go to the moon for them." Middle-aged people cover their nose and mouth with one hand to prevent inhalation of poisonous smoke, while looking at the watch on their wrist, calculating the high school survivorship How much time is left, until there is no sound in it, and the smoke from the lunar module is getting bigger and bigger, and there is no more room to stay, the middle-aged talents ran to the door, pushed the door open, changed their expression of panic, and shouted "No, fire!"
