128 Chapter 128 Bamboo Dragonfly

The nightmare of the second battalion commander did not stop there, because he finally saw clearly that the two commandos who fell were the shooters of the Iron Fist 3 team, and they had just taken advantage of the drone bombardment to run to a place with a wide field of vision to launch rockets, and when they saw that the rockets accurately hit the target, they thought they had destroyed the concrete business, and they moved a little slower and were directly hit by machine guns.

More than 200 meters away from this concrete fortification, a company commander lay in a shallow crater blown out by a mortar, machine gun bullets whizzed overhead, his heart was also broken, raised his hand to look at the watch, there was still one minute left before the battalion commander stipulated the time for the whole company to charge, the concrete fortification in front of it was still spraying these three fire dragons, and the whole company of more than 100 people may not even be able to rush 100 meters in the face of such a dense rain of bullets, so they must be reimbursed for all.

However, the military order is difficult to disobey, although they die mercenaries, but they also know that as soldiers, even if they die, they will also die on the way to charge. He waved back and said loudly: "Trumpeter, look at my gestures, listen to my orders, prepare to blow the trumpet, and charge the whole company!" ”

"Yes," the trumpeter replied from a shallow pit behind him.

At this moment, the commander of a company heard a slight buzzing sound overhead, he knew that it was the small plane of the UAV detachment coming again, he couldn't help sighing, the miniature bomber just now dropped dozens of bombs and did not see any effect, even the Iron Fist 3 bazooka specially used to deal with the fortifications failed to blow up this concrete fortification, what role can these small planes play?

However, he could hear that the hum was different from the last time, it seemed to be more rapid and powerful, could there be a bigger plane? He couldn't help but look up at the sky, and was immediately disappointed, this time there were only two, or the same small plane as the previous time, what effect could it play?

Wait, it seems to be a little different from the previous times, well, under the belly of these two small planes, each has an explosive bag bigger than a bucket, I'm afraid it weighs 30 kilograms, right? I heard that these small planes can only take off with a maximum of 15 kilograms of objects, how can these two planes carry such heavy objects? Far overloaded, huh? Thinking of this, the company commander looked curiously at the two drones flying overhead, and looked at the two oversized explosive packets under the belly of the plane, hoping that they could create a miracle, and he was not in a hurry to give the order to charge death.

At this time, two small planes had already passed over his head and were climbing to a higher altitude towards the concrete fortifications. The commander of the company was surprised to find that these two eight-axis small planes, in addition to the eight axes are 16 small propellers on the two floors of the mountain, there is a larger propeller on it, which covers the entire fuselage, just like the propeller on the helicopter.

This peculiar sight made the first company commander feel incredible, he had never seen such a peculiar design.

In a surprise moment, two drones have flown to the concrete fortifications over a hundred meters above the place, although it is night, but around the fortifications around the explosion of a lot of incendiary materials are still burning, through these fires, I saw two huge explosive bags have fallen in the night sky. As soon as the explosive bag fell off from under the belly of the plane, the two drones that had lost their load rose into the air and flew up for more than 20 meters, until the bamboo dragonfly above their heads stopped spinning, stabilized their bodies, and disappeared into the night sky faintly.

Almost at the same time as the drone disappeared, there was a earth-shaking explosion from the concrete fortifications in front of it. As far as the eye can see, the concrete fortifications are drowned in the smoke of the explosion, and at the same time as the explosion, countless fires splash in all directions, and that scene is like a boulder thrown into the hot magma, flying out countless sparks, forming a spectacular fire tree silver flower.

The explosion was so powerful that some small sparks flew up to two hundred meters away. Unfortunately, one of the broad bean-sized balls of fire stuck to a company-long steel helmet, cracking the paint on the outer layer of the steel helmet. The commander of the first company hurriedly took off the steel helmet and reached out to slap the flames, who knew that the tentacles were sticky and sticky to the fingers of the company commander, and burned on the fingers of the company commander, and the company commander screamed in pain, and hurriedly slapped in the ground, who knew that the more the fire became stronger, the fire burned even bigger, and even his palm was on fire.

At the critical moment, I don't know who shouted: "It's napalm, you can't beat it, quickly wipe it off in the dirt." When the company commander heard this, he hurriedly inserted his palm into the soil, and after a few painful inspections, the sticky thing was finally stuck by the soil, and the company commander's hand was no longer on fire, but the soil around him continued to burst into flames, and he was shocked in his heart, what is this, so domineering? Suddenly, I felt the pain in my palm, and looked down, only to see that the palm was burned out of a scar the size of a copper coin, and the flesh and blood were blurred, and yellow water was falling out.

At this time, a loud noise came from the direction of the concrete fortifications again, and the company commander looked up, only to see a fireball rushing out of the concrete fortifications, instantly surrounding the entire fortifications, this fire, with a large amount of smoke in the blood red, like a refining fire from hell, devouring everything it encountered. It turned out that the first explosive bag blew up a gap, and the second explosive bag fell inside the fortifications, where a fire ignited and engulfed the entire fortifications.

The first company commander was a veteran for many years, and immediately saw that the opportunity was coming, and he didn't care about the pain in his palm, and said loudly to the trumpeter: "Trumpeter, blow the trumpet immediately, all the brothers of the company, rush with me!" With that, he was the first to jump out of the crater and rushed towards the fortifications in front of him. He had barely taken a few steps when a loud charge sounded behind him, and countless warriors jumped out of the trench and rushed forward. Running and running, the commander of the first company felt that something was wrong, and there seemed to be a momentum of thousands of troops behind him, far more than the size of his company, and he couldn't help but glance back, and the dark night was full of about enough figures, and the mountains were full of people, rushing towards the fortifications.

At this time, the public works were full of blazing fires, which were illuminated as daylight. Due to the destruction of the searchlight and the failure to re-fire the flares in time, the second battalion in the charge was well covered in the dark. And the terrible concrete fortifications, which were blazing from the outside to the inside, were initially seen one or two people on fire screaming and rushing out of the fire, and fell down after jumping a few steps, and there was no more news. Suddenly, only the sound of crackling and burning remained, and occasionally a cluster of flames burst out with a loud bang, which was the detonation of some ammunition, and could not pose a threat to everyone after all.

At the Ziyan base, next to the woods and on the grass, a group of people were watching the video silently, and the tragic scene of the concrete fortifications deeply shocked everyone. I didn't expect that the napalm of the foreign girl cottage had such a great power, and I didn't expect that this small civilian drone, with a fixed load of only 15 kilograms, actually pulled up a 30-kilogram explosive package and accurately threw it onto the concrete fortifications 10 kilometers away.

I only heard Wang Xiaoyu say with emotion: "You still say that we are a cottage, I think you are the ancestor of the cottage, just look at the power of your napalm, you might as well make more than the military napalm QI oil bomb!" ”

Yang Niu smiled and said: "Some people say that those who are close to Zhu are red, and those who are close to ink are black." Born in Huaibei for orange, born in Huainan for citrus, there is fertile cottage soil, I am naturally orange. ”

Wang Xiaoyu said: "Anyway, your imagination still surprises me, how did you think of loading a bamboo dragonfly on top of the drone, without changing the other structures of the drone, to double the lift generated by the drone?" ”

The girl said, "You taught me." ”

Wang Xiaoyu said: "Don't be kidding, I only saw the trick of installing a bamboo dragonfly on the top of the drone for the first time, how could it be that I taught you?" ”

The girl said: "You really taught me, remember what you said when you changed the propeller of the drone to a double layer?" ”

Xiao Shancha next to him interjected: "I remember, Brother Xiaoyu said that the high-pressure and high-speed airflow generated by the upper propeller will make the lower propeller improve work efficiency, thereby increasing lift." ”

Yang Niu said: "That's right, so when I modified the drone 20 days ago, I thought of this problem, if you add an engine on the top of the drone and use a larger propeller to provide lift for the aircraft, so that this propeller provides high-pressure and high-speed airflow for the two small propellers below, so that the two layers of propellers below improve the work efficiency, can't it provide greater lift?" So at that time, I added two pairs of model helicopter propellers and the corresponding electric motor to the list of materials you bought for the paper battery, but it was someone else who paid for it, and you didn't look at the list carefully. ”

"Hehe", Wang Xiaoyu smiled embarrassedly, and asked: "The helicopter propeller will produce a torque distance, which will make the aircraft lose control, so the general helicopter tail rudder also has a small propeller that provides the opposite force distance, but these small drones are not there, how did you do it?" ”

The foreign girl looked at Wang Xiaoyu strangely, such a simple question, will this guy who plays drones not understand? Why did he knowingly ask? Yu Guangzhong unconsciously caught a glimpse of the little mountain tea with an expectant face on the side, and his heart was white, this guy is going to take the opportunity to teach his apprentice, okay, then cooperate with him once. So he said: "The propeller I installed is two layers, and the two layers of propellers of the same size rotate in opposite directions and have the same speed, so their force distance from each other cancels each other out, so there is no need to install a small propeller with resistance distance." ”

"You're amazing! To come up with such a brilliant idea! Xiao Shancha looked at the foreign girl with admiration on her face.

"I didn't invent the idea of these two propellers rotating against each other, 50 years ago, the Soviet Tu-95 bomber was equipped with this kind of propeller, and it is still in use today." There are also some helicopters on the market that are also equipped with this kind of counter-rotating propeller. Especially in your Huaxia, the drone model aircraft in the toy store, 8 out of 10 are equipped with this kind of counter-rotating propeller, how about it? Go back and ask Brother Xiaoyu to buy one for you? ”

"This can be had!" Xiao Shancha jumped up excitedly and turned to look at Wang Xiaoyu.

Wang Xiaoyu was bent on learning more knowledge from Xiao Camellia, pretending not to see it, and then said: "You only installed the motor and propeller on the multicopter drone, and did not install the control system in the helicopter, which saved a lot of weight." However, because of this, this bamboo dragonfly can only provide lift and cannot fly like a helicopter. ”

"Yes, the flight control relies on the drone below, and the bamboo dragonfly above simply provides lift. Take the two drones that just dropped the explosive package as an example, its flight control is completely completed by the plant protection drone, and the bamboo dragonfly on it is only responsible for providing 18 kg of lift, so the moment the explosive package is dropped, the drone that loses the load will suddenly rise dozens of meters. ”

"I know, so after throwing away the explosives pack, you turned off the bamboo dragonfly, and the drone flew back with the bamboo dragonfly flying normally," said Koyama Cha. ”

Yang Niu said: "By the way, such a smart little brain, if you don't remember to play all day long and study hard, you can become a doctor or a lawyer in the future." ”

While he was talking, several loud noises sounded from the other side of the mountain, flashing a series of explosions, and a soldier hurriedly walked out of the cave, came to Wang Xiaoyu's side and said, "Mr. Wang, the operation of the guard company to bombard the artillery position has begun, and the company commander asked if you want to come in and have a look?" ”

Wang Xiaoyu has been tossing and turning in the mercenary alliance for more than 20 days, the purpose is to blow up the artillery position on the opposite side and rescue his cousin Moon, how can he not go to see it? As soon as the soldier finished speaking, he hurried into the cave.
