readx; Lu Zhu and Luo Guanghui took the elevator up to the twenty-eighth floor and opened their combination lock security door.

The pen "Fun" Pavilion www.biquge.info entered the house, and Lu Zhu let Luo Guanghui sit casually, but he ran to the bedroom and opened the window, and a cool breeze followed the two planes in.

Boom Twenty landed on the floor, and the Wuzhi Eighteenth helicopter landed on the bed.

Luzhu reached out and touched the two engines of the boom twenty a little hot, it is no wonder that it is more than a thousand miles back and forth from K City to D City.

Except for one mission in the middle of Wuzhi 18, this H-20, which resembles the shape of a bat, has a bomb hanging in its stomach like a rolling shutter door, and a model of 180 bombs is hung.

There are also two models of cruise missiles hanging under each wing, and they are constantly flying in the sky.

It's just that the H-20 still has a thorny problem that needs to be solved, that is, when flying at subsonic speeds, it can still be completely invisible.

If it flies beyond Mach 2, it is semi-invisible.

Luzhu has been thinking about this problem all the way, and the key is the air intake of the engine, as well as the heat generated by the engine running at high speed at more than Mach 2.

Is there any way to solve these two problems?

The first thing is to improve the air intake, change it to a small S-shaped air intake with unevenness, and add a layer of ink and charcoal in front as a compartment, which may be better.

The second problem is not so easy to solve, if the aircraft wants to fly to a speed above Mach 2, the engine speed must be increased accordingly.

With the high temperatures emitted in the combustion chamber with jet fuel, the question is how to cool down a high-speed engine?

To solve this dilemma, we must understand how aircraft engines work: air intakes, compressors, combustion chambers, turbines, nozzles.

If it is a military engine, its turbine and tail nozzle also have afterburner.

The engine first draws air from the intake tract and then into the compressor, which is used to increase the pressure of the inhaled air.

Increases the pressure and temperature of the airflow.

Then the high-pressure air flow enters the combustion chamber, and the fuel nozzle of the combustion chamber shoots aviation oil, which is mixed with air and ignited, generating high-temperature and high-pressure gas to be discharged backwards.

This creates a reaction thrust to the engine, which drives the aircraft forward.

There are generally two methods used to cool down, one is ice water and the other is cold air.

It's like in the dog days, people want to eat a popsicle and ice cream in order to cool down.

It's too hot in the house, the folding fan is rocked in ancient times, and the air conditioner is turned on in modern times.

Oh, just turn on the air conditioner!

Luzhu slapped his head, yes, why can't you install a compressor next to the intake tract of the engine, just like a household air conditioner, put an internal hook-up machine on the outer cover of the engine, the compressor and the compressor rotate the same, one increases the internal temperature, and the other lowers the external temperature, doesn't it solve the problem of overheating of the Mach 2 engine and not invisible?

Luzhu thought of this and felt a burst of ecstasy, and suddenly heard the sound of the security door, followed by a cry, "Wife, what are you doing in the bedroom?" ”

After Li Mo entered the house, he couldn't see the green bamboo, only Luo Guanghui was watching TV, so he shouted in such a voice, "Hurry up and come out to entertain the guests!" ”

Luzhu was so fascinated by it in the bedroom that he really forgot about Pepper for a while.

After hearing her husband's shout, she hurriedly put Wu Zhibai on the safe and put Bang Twenty on the dresser, opened the bedroom door and walked out.

smiled and said, "Sister Luo, I'm going to eat here today, and after dinner, our husband and wife have something to say to you!" ”

"You go cook some porridge and heat up the barbecued pork buns and Kowloon buns we sell!"

Li Mo opened the refrigerator as he spoke, took three pieces of ice cream from it, gave one to Luzhu and one to Luo Guanghui, and sat on the sofa watching TV with Luo Guanghui.

Luo Guanghui moved his body to Li Mo's side and asked, "Didn't you say yesterday that you would go to City D today?" I think you should have been there, if there is anything good or bad, you must tell Sister Luo without reservation! ”

"From yesterday to today, did Guan Sheng call?"

Li Mo asked, "Does he care about you?" ”

"Yes, I made 12 phone calls a day, and most of them asked if they had eaten? Is your body okay? When you go to bed at night, you should cover yourself with a sheet so that you don't catch a cold. What's wrong? ”

Luo Guanghui stared at Li Mo with frightened eyes, as if indicating that something bad was about to happen, and asked anxiously, "Did you learn something bad or untrue?" ”

"Alright, let's eat!"

Before Li Mo could answer Luo Guanghui's question, he heard Lu Zhu shouting in the kitchen, "Husband, come over and help Duanduan!" ”

Luo Guanghui picked up the remote control of the air conditioner on the coffee table and turned up the wind speed of the air conditioner by two levels.

Then he went to the bathroom and washed his hands, and also helped put the small bamboo basket containing the buns on the dining table.

Li Mo stretched out his hand to take the bun to eat, but was lightly slapped on the back of his hand by Luzhu, "Wash your hands!" ”

Li Mo stuck out his tongue, grimaced, and walked towards the bathroom.

"I'm so jealous of you!"

Luo Guanghui picked up the bowl, drank a sip of rice porridge, and said, "You little husband and wife are really affectionate, the husband is long and the husband is short, it is really slanderous!" ”

"Husband and wife should respect each other as guests, and love is long!"

Lu Zhu put the bamboo basket containing the small bag and pushed it in front of Luo Guanghui, "Eat the bun!" ”

Li Mo came out of the bathroom and sat down at the dining table to eat.

Luo Guanghui was in a nervous mood, and she knew in her heart that Luzhu called her over this time, and she must have learned bad information from Guan Sheng's house in D City.

So she only ate two small buns, drank a bowl of white porridge and left the table.

Li Mo can really eat it, and a bamboo basket of small buns made him eat a clean light.

After eating, Green Bamboo cleaned up the pots and bowls.

Back in the living room, let Li Mo go to the bedroom to watch his "Military Intelligence Observation Room", because some words are still easy for two women to talk together.

Luzhu saw Li Mo go to the bedroom, and said to Luo Guanghui, "Now it's just the two of us, I want to ask you how he wanted you for the first time?" ”

"It was during an outing, and he said that after staying in this mahjong-like cement brick stomping for a long time, he wanted to smell the atmosphere of the mountains and play in the countryside for a day."

Luo Guanghui seemed to fall into the memory of recalling: "That day, like an angel, he happily led him to a mountain called Meiling, sixty miles away from K City. We picked flowers on the grass, frolicked, and fluttered butterflies. Chase in the woods, catch fish and shrimp in the creek. While I was having fun, it was pouring rain. He took me by the hand and led me to a cave to take shelter from the rain, and it was in this cave that he asked for my virginity. ”

When Luo Guanghui said this, seeing that Luzhu's demeanor was unusually solemn, he asked, "I told you all about me, what happened to you?" ”

"You have to be mentally prepared."

Luzhu paused, looked into Luo Guanghui's eyes, and continued, "You have been deceived! ”

As he spoke, Luzhu took out his mobile phone and put a video for Luo Guanghui to watch.

The picture is the white villa, and as the camera progresses, a fashionably dressed woman appears in the house.

Luzhu told Luo Guanghui that this was Guan Sheng's wife, Ling Ziwei, and that she and Guan Sheng had been married for many years, but had no children.

This villa is a wedding house bought by Guan Sheng's parents for the two of them, and I heard Ling Ziwei say that she and Guan Sheng have a very good relationship, but they lack a man and a girl.

Luo Guanghui shed tears while watching, and only said one sentence in his mouth: "This thing with a beast's heart, I want him to die a good death!" ”

Then he didn't say anything, and he was about to get up and say goodbye with his bag.

Luzhu was afraid that Luo Guanghui would not be able to think of doing something stupid for a while after learning the truth, so he called Li Mo to let him drive him.

Luo Guanghui smiled, put on a nonchalant look, and refused Luzhu to ask Li Mo to drive her, saying that a person wants to be quiet and quiet, so that they can rest assured that nothing will happen.

Luzhu was still not at ease, so he sent her to the elevator and watched her get on the elevator before returning home.

When he entered the door, Li Mo had come out of the bedroom, sat on the sofa in the living room, put the computer on the coffee table, and continued to watch his favorite military channel.

"Gone?"

"Let's go, nothing will happen, right?"

"No, with her big and fiery temper, she won't be unable to think about it."

Li Mo pulled the green bamboo to sit beside him and said, "I'm tired enough today, I've run more than a thousand miles." After you answer a question from me, go and put the bath water, and let's take a mandarin duck bath. ”

"And what questions do you have to ask?"

"You said that if war breaks out in the future, will the first shot be fired in the South China Sea or in the East China Sea?"

"Tokai!"

Lu Zhu thought for a moment, and then replied, "You don't see that the South China Sea is very troublesome, and you won't go wrong in the South China Sea." The most important thing to pay attention to should be in the Bohai Bay and the Liaodong Peninsula, because first, it is close to the mainland of the plaster country, and second, the way they invaded last time is familiar! ”
