Wei Jie Says:

"Qingxu, don't be so excited, just be generous, don't die, which of the artifacts in this world is the thing that makes people die? Why don't we go and see Kunpeng now, there's no point in opening white teeth! ”

The important ministers came to the first line of heaven and entered the machine shed, this machine shed is a frame without a roof, and fortunately borrowed the cliff and rock walls on both sides of the first line of heaven, as long as the military village is erected at both ends, it can be used as a machine shed, but the military village is blocked by wooden planks.

Entering the hangar, many people exclaimed, indeed, the Kunpeng airship made them artificial things that they had never experienced.

Song Aoxing looked at everyone proudly, and introduced softly:

"The Kunpeng airship, with a total length of 19 zhang and 9 feet, and the largest diameter of the circular hull is 6 zhang and 6 feet, all of which are tied with bamboo knots, and the swim bladders are filled with hydrogen gas, and the silk threads are tied and sealed, and thousands of fish bladders are put into ten compartments respectively, and the compartment is cotton cloth, and the middle of the cotton cloth passes through many copper wires, and is connected with the binding iron wire and copper wire of the whole airship.

Hydrogen is obtained by electrolysis of brine by a wind-blade generator, and additional oxygen is collected for the rescue of dying wounded soldiers and the smelting of metal.

The decomposition of brine also obtains a large amount of caustic soda, which is very corrosive, and some of it is dried into powder and loaded into rockets to enhance certain properties.

In fact, we have followed the instructions of the present and used pig fat and fish oil to make soap, which is much better than soap horn and pig pancreas. By the way, there is also glycerin, which is used to wipe hands and faces, antifreeze, better than wax, and cheaper. ”

After speaking, Song Qing had already rushed over with a bunch of masters, and some auxiliary workers had already taken out the soap contained in the wooden box.

Minister Yang opened the lid very familiarly, pointed to the red, red, yellow, yellow, green and green soap and said: "These two are the moon season flowers, which are chlorophyll." ”

Then he opened the glycerin in the porcelain bottle: "This white glycerin is 70% water, and it is the best for water retention and skin rejuvenation; It's rouge-tinted, and the blush couldn't be better. Oh, the production is enough recently, so I will send some to each soldier, but the porcelain vase is not enough, and the female general has no time to make containers. ”

Tu Xicai's face turned green: "That, Song Yuanzheng, these good things, even if there are no porcelain bottles, they are used in barrels, which are also good." And even I don't know! Able to prevent frost handguards, this is military funding, military funding! ”

Mi Simei hid behind Minister Yang and said: "Marshal, now I'm busy with Kunpeng, that one has only made less than a hundred catties, and there are not many grease warehouses, and now the big animals are dead and now they are mainly used for military rations, and these glycerins are mainly scraped out of the caught fish, and the fish oil is too fishy, so I am willing to do this." ”

Hong Shan immediately said: "It doesn't matter, our Yashan militia can fish, if we can catch that kind of Kunpeng big fish (whale), I'm afraid there are hundreds of thousands of catties." But we have too few big boats for small boats to catch that kind of fish. ”

Song Aoxing said proudly:

"If the Kunpeng airship can fly in the future, that kind of Kunpeng big fish will not be enough for you to see."

Tu Xicai said:

"Yes, yes, that's exactly what I want to say about the Kunpeng airship."

Song Aoxing continued:

"The airship propulsion, which is divided into two parts, front and rear;

Two propeller blades are used in the front, which are rotated by an electric motor, and there is a guide sail in front.

There are detonation jet thrusters in the rear.

According to Lin Xi's drawings, the jade master took a group of craftsmen in the car, and made a propeller propelled by an electric motor with his hands and simple tools. ”

The car knew that this was Song Aoxing's chance to show his face, so he took everyone into the propeller:

"The blade diameter of this propeller is about four feet, which is arranged at the front end of the pod, because the magnet production is too difficult, so the coil wound by wrought iron winding tung wrapping wire is used, and the excitation is carried out after the power is turned on, in fact, it is a DC brush motor, and the brush is made of graphite blocks, and the brushes need to be replaced frequently, so the weight is reduced a lot, and the most important thing is to be able to fly up in the sky.

This is the command and communications station."

After explaining, the intercom was pressed in the car, and a voice came from the horn: "Ready for the propeller thruster to test run, ground crew, see if it is tied and fixed?" ”

After a while, a reply came from the loudspeaker of the communication station: "The ground crew has completed the inspection, and everything is firmly tied." ”

The car pressed the radio button again: "Detonation jet engine set ready, propeller set ready for test run." ”

With that, he pushed a huge brass wrench up, which struck a spring bell with a clanging sound;

Immediately the voltage pointer on a panel floated to the position of 220, and the ammeter was still motionless, and then he continued to move one of the copper wrenches, and the ammeter suddenly hit the position of 10, and the motor hissed and rattled sound, and then rotated, and after a while, a huge wind blew up;

When everyone was surprised, a copper wrench was pushed up in the car, and the wind speed suddenly increased again, and the ammeter rose to the 20 position.

Then the car waited until the wind was more or less stable, and continued to push the third brass wrench up, and although the center of the propeller was about three feet above the people's heads, the huge wind still blew on the people, and the speech was almost inaudible.

The car pulled back three copper wrenches, and then touched the shell of the motor: "It's a little hot, we can't continue to increase his speed." ”

Minister Yang asked: "With such a strong wind, it must fly very quickly?" ”

The car smiled: "Minister Yang, the Kunpeng is twenty zhang, and the diameter of this blade is only four feet, and the wind is very strong in the place where we stay, but to push such a large Kunpeng, this power can only be regarded as mildly ruthless." At best, it's like a walk.

If you want to be fast, you have to use this thing that Imagami gave us, the detonation jet thruster. Let's take a look at this, adults. ”

The Pope said, "Go down, and I'll be on it." ”

Minister Yang also said: "Then I won't go down." ”

The car scratched his head: "Don't hide it from your lords, this kind of thruster is too tyrannical now, and everyone can't hear the speech clearly on it, so let's all go down." ”

So everyone went to a platform next to them, in addition to the pod.

A bearded man walked over and hugged him in the car: "Xingyue Gong, everything depends on you." ”

The one called Xingyue Gong made a weekly salute to everyone, and everyone also returned the salute, Xingyue Gong said: "The old man has to see this divine beast, and he knows that what the Mo Sheng said in the past is true, and today the old man is still healthy, and there is still hope to fly, therefore, the old man is not talented, and he has made three, but it is a pity that the Kunpeng airship is too fragile and can only accommodate two small ones. ”

Lin Xi said: "Since you ask Zhou Liting, I will naturally treat him as a court." ”

Xingyue said fairly: "The old man wants to give the old man a quick flying masterpiece today, and the old man wants to fly to the moon in his lifetime and take a look at the fairy of the Moon Palace, which is the childhood dream of the old man." ”

Lin Xi laughed and said: "I don't have an opinion, it's just that Xingyue Gong has to work hard to live a little longer and work faster, of course, this is a victory for us today, and we can talk about other things if we survive." ”

Xingyue Gong proudly puffed up his chest and stroked his beard: "These three thrusters, the old man personally proofread them one by one, tested them one by one, reinforced them everywhere, they have all done several rounds, one hundred and eighty trips, the old man dare not say, this time to kill the enemy, within five hours, if there is damage, just ask me today, and the old man will come to see me." ”

Lin Xi nodded: "Master Weijie, you write it down, set up the Star and Moon Medal and Medal today, and if there is a flying meritorious service, it will be rewarded in the future." Set up gold, silver, copper, iron and other four grades, engraved with the sun, moon and stars. ”

He also said to Xingyue Gong: "The day Kunpeng kills the enemy and returns to the warehouse, it is the time when the Xingyue Gold Medal is awarded. ”

Xingyue Gong didn't speak, waved his hand and took the two boy-like looks, saluted together, and then walked up to the pod, first checked a circle, and then began to step on the compression, pressed for a while, checked it, and then tinkered with the front end of the jet thruster for a while, and then pushed a copper wrench up, only to hear a crackling sound, and then the tail of the nozzle suddenly detonation and roar, soon, the detonation sound continued, and it was also smaller, but the fire at the end of the nozzle became longer and longer, and finally the fire was more than four feet long, The blazing wind blew, and the boy quickly pulled the brass wrench down. Then another one was tested.

Everyone was shocked, and Xingyue Gong walked back again:

"Ladies and gentlemen, the detonation jet thruster is very ingenious, speaking in principle, it is also a very simple thing, this thing is an intermittent thruster, one with, that, today, called the Laval tube structure of the big horn, in the combustion chamber at the front end of the Laval tube, there is a group of copper and graphite cores with serrated teeth, after starting the engine, this pair of sawtooth will tear and tear the radial arc, and there is a row of gaps at the upper end of the combustion chamber, spraying some fire oil or high-concentration alcohol, of course, the current technology is still very primitiveThere is no high-pressure oil pump, but there is a semi-sealed cylinder with closed beads on it, and then a pump cylinder pressurized by air is added, and by pressing the pump, the cylinder of oil or alcohol is increased by a considerable pressure. The injector also has a pressure-sealing bead encapsulated in an automatic control valve with a gap at the top and a round hole at the bottom.

To activate this pillow jet thruster, a certain amount of alcohol is poured through a perfusion valve, and then the leaf reeds will reseal the inlet.

At this time, the electric spark is activated, the spark is for a period of time, the alcohol on the liquid level will evaporate, resulting in a combustion explosion, which will push the sealing column in the gap above the combustion chamber open, and then the U-shaped tube in the pressurized oil tank will have oil or alcohol, which will be pressed into the combustion chamber.

If there is a lot of fuel in the combustion chamber, when it is sprayed out of the throat of the Laval tube, it may be re-ignited, so that the tail nozzle will emit a frequent tail flame.

After several days of testing, the combustion chamber was about one foot long, the maximum diameter was six inches, the total length of the Laval pipe and the throat was slightly shorter than one foot, the smallest throat diameter was less than one inch, the length of the tail nozzle was about three feet, the maximum diameter was almost three feet, and the longest tail flame was more than one foot long.

In fact, in the manufacture of hot air balloon nozzle equipment, this kind of pressurized nozzle is already relatively mature, and the engineering institute is basically aware of the problems and opportunities. ”

Tu Xi saw it and was very happy:

"It's so powerful, can you put it on the car and breathe to kill the enemy?"

Xingyue Gong shook his head:

"This structure, the reliability is not high, especially the reliability of continuous deflagration is not high, this thing needs oxygen in the air to combustion, but our current structure, the most ingenious direct combustion with natural tempering, so, there is a large part of the combustion is done in the tail nozzle, the main role of the combustion chamber is currently fuel atomization gasification accelerated injection.

It's just that these are not particularly harmful to equipment such as airships, which do not have strict requirements for propulsion, and in the case that the Mengyuan coalition army does not have an air force.

The specific gravity of hydrogen given by today is much smaller than that of air, according to the experimental data of today, per cubic abbot, the weight of cold air is about 21 to 22 catties, the hot air balloon is boiling to steam, that is, 100 °, and the weight of air is about 16 to 17 catties per cubic abbot, so heating the balloon can obtain about 5 to 6 catties of buoyancy per cubic abbot, but if hydrogen is used, each cubic abbot can obtain 16 to 18 catties of buoyancy.

This difference is too tempting, but the only bad thing is that hydrogen is too easy to burn. So the hydrogen balloon inside must not see Mars.

When the Kunpeng airship flies in the air, the hot air from the tail nozzle will be cooled by the air quickly, which is not easy to cause accidents.

But when mounted on a chariot, it is easy to be counterattacked.

The total design lift of the airship is about 200,000 catties, the empty weight without crew and ammunition is about 60,000 catties, and the maximum take-off load is about 140,000 catties.

The airship's pod is three feet long, and can hold five to six soldiers, including a navigator and a communications officer, a captain and steerer, a mechanic, and the remaining two or three attackers.

The airship guide is mainly based on the propeller and rudder surface, and the detonation engine is too fierce, the rudder surface cannot be placed in the back, and it will be burned out, so in terms of layout, this kind of airship is the front traction guide.

In the case of straight-line acceleration, the speed of the airship can reach about 60 miles per hour at the fastest, which means that under low wind speeds, the airship can still have a certain sailing ability.

With two detonation engines for afterburner, the speed of the airship can reach more than 100 miles per hour at the fastest, but in this case, the bamboo structure of the airship is already risky. ”

。。。。。。

On the evening of the 23rd, the storm stopped, the Xuanyi Army raised the Kunpeng airship, carrying 20 cloud burst bombs, and went straight to the headquarters of the Mengyuan Army on the west side of Yashan Island.

Since the Kunpeng airship flew at a much higher altitude than the hot air balloon without power mooring, it rose to a height of four or five hundred steps above the ground, and the bump formed by the cloudburst bomb traveled in this direction, and the impact was far smaller than that on the ground, and the twenty cloudburst bombs did not cause damage to the Kunpeng airship.

Then, with two long tail flames, the airship roamed in the sky, cruising in all directions, and everywhere it went, ghosts cried wolves.

In the early morning of the 24th, the Kunpeng airship took off again, this time, almost all of them needed to carry the fire yaksha, from Hongguanya to the north along the Okura line, the bombing and shouting were endless, all the way to kill the Mengyuan coalition army on Yashan Island, this time there were no rebels, because all the Han people who were not in the Xuanyi Army were identified as the Mengyuan enemy army, and after flying to the North Island, Yashan Island had almost no soldiers to see again, and they were all rushing to the Yashan Mountain West Sea Road, rushing to get on the warship and the lucky ship.

In the evening, when Shen Shi, the Kunpeng airship took off for the third time, along the Yashan West Sea Road, squeezing the warships and sailing ships to the north, except for the defenders of the second layer of the Eagle Beak Rock, the Xuanyi Army marched north in a scattered line, and all the sailors boarded the boat, and the followers of the Kunpeng went forward to harvest.

On this day, the sea was full of floating corpses, the Xuanyi Army's naval army and the Celestial Army burned and destroyed all the resisting ships in their path, and the three submarines were equipped with horizontal knives, surfaced, and were dragged by small loach boats, advancing along the way.

All the warships and ships that surrendered were left behind and driven into the sea to fend for themselves.

On the morning of the 25th, on the Yashan West Sea Road, there was not a single Mengyuan ship except for the ships moored along the way.

Fan Wenhu, the marshal of the Mengyuan coalition army, once again did not know what to do, and was likely to be sniped by the Xuanyi army again.

All the Mengyuan on the dry village scattered and fled.

On the 28th, the whole territory of Xinhui County was recovered.
