"Everyone, be unimpatient, and listen to me one by one. Pen "Fun" Pavilion www.biquge.info" Li Hongfei interrupted everyone's discussion.

Knowing that the researchers present must have been incomprehensible when they heard this decision, Li Hongfei could only explain patiently.........

A hot air balloon is a vehicle that heats the air with a burner to make the air less dense, thus generating buoyancy, and relies on the external wind to control the speed and direction of the flight.

As for the choice of gas, hot air balloons can not only use air, but also can choose to use hydrogen or helium, and hot air balloon air bags are also divided into two types: unsealed and sealed.

The airship is a sealed hot air balloon filled with less dense hydrogen or helium to create greater buoyancy, and an additional thruster is added to control the airship's forward and backward movements.

It can be said that the flight principle of a hot air balloon is not much different from that of an airship, the only difference is that the airship is equipped with thrusters.

With the current level of craftsmanship in the Ming Dynasty, it is not difficult to manufacture sealed airbags, and the only problem that needs to be overcome is the collection of thrusters and hydrogen, as for the safer and more stable helium....... Not under consideration for the time being.

"The collection of hydrogen, through the research of the past few years, has made some progress, but this propeller ........ As expected by the old decay, it should be related to machinery, not the old decay. After listening to Li Hongfei's explanation, Song Yingxing took the lead in speaking.

A few years ago, when Li Hongfei proposed the research and development plan of hot air balloons, he mentioned the use of hydrogen instead of air, because the time of hydrogen in the air is much longer than that of air.

When making a hot air balloon, a double-layer airbag is sewn, and the outer wall to the middle airbag is filled with enough hydrogen to ensure balance, and then only the innermost air needs to be heated to ensure the heat required for lifting, which can greatly save fuel and increase the time spent in the air.

This method is not much different from the principle of hot air balloons in later generations, but it is difficult to collect hydrogen, even top scientists like Song Yingxing are difficult to collect enough hydrogen in a short time.

As early as the 16th century, the famous Swiss physician Parases described the production of a "flammable gas" when iron filings come into contact with acid.

In the 17th century, the famous Belgian scholar of medical chemistry, Helmont van Helmont J (1579-1644), came into contact with this gas by chance, but did not separate and collect it.

Although these two scientists only discovered the existence of hydrogen and failed to collect it effectively, the personnel sent to Europe by the Ming Dynasty also obtained the method of hydrogen production.

When the crew brought this discovery back to Daming, Song Yingxing began research on the production of hydrogen.

He first used iron, zinc, etc., combined with dilute sulfuric acid and dilute hydrochloric acid to produce "flammable air", that is, hydrogen, and collected it with the drainage gas collection method mentioned by Li Hongfei at the beginning.

The collection of hydrogen by the drainage gas collection method is actually a water electrolysis experiment done by Li Hongfei in junior high school chemistry.

Li Hongfei only knows that oxygen and hydrogen can be obtained by electrolysis of water, and when the current passes through water (H2O), hydrogen (H2) is formed through reduced water at the cathode, and oxygen (O2) is formed by oxidizing water at the anode, and the amount of hydrogen produced is about twice that of oxygen.

But the problem lies in this electrolytic water, where does the electricity come from in today's Daming?

If it weren't for the new hydrogen generation scheme from Europe, Song Yingxing would have to go crazy in order to make "electricity".

Although the electrolysis of water is not practical, fortunately, the drainage gas collection method is still practical, and the problem that Europeans can produce hydrogen but cannot collect it has finally been solved in the hands of Song Yingxing.

Hydrogen is manufactured and collected, but the production of hydrogen balloons using metal and acid production methods cannot meet the huge demand for hydrogen balloons, and the current storage technology is not up to standard, making it difficult to mass produce and store.

That is, it is almost impossible to produce at full capacity, to meet the needs of a hydrogen balloon to lift into the air, to store it in large quantities for military use.

So Song Yingxing and his team began a year-long research, and their research direction gradually evolved from how to store hydrogen at the beginning to how to use other substances to produce hydrogen.

After continuous research, Song Yingxing finally invented a new hydrogen production method - strong alkali and aluminum or silicon hydrogen production method.

Strong alkalis and aluminum or silicon can directly produce hydrogen, and only hydrogen is a single gas.

That is to say, there is no longer a need to use the so-called drainage method, just put strong alkali and aluminum on the hot air balloon, and then design an inflatable device, you can directly flush hydrogen into the air bag (later generations generally inflate civilian hydrogen balloons, this method is used).

When Li Hongfei proposed the airship plan, the biggest problem Song Yingxing raised was not how to collect hydrogen, but how to build his own propeller.

"Thrusters are a real problem, but you should think about it from a different perspective, for example, is the sky not much different from the ocean? How different is a hot air balloon that uses the wind to propel forward and a warship in the water and uses sails as power? Li Hongfei provided an idea.

Indeed, in the past, warships could gallop in the water, in addition to relying on the current, more relied on sails as power, of course, these are all forces in the same direction, if you want to change direction, you need to rely entirely on oars.

"You mean, we put oars on hot air balloons?" Some people reacted quickly.

"It seems to work, everyone fans on weekdays can also create wind, and the bigger point of the fan may not be able to urge the hot air balloon to change direction."

"If possible, we can also put a steam engine on a hot air balloon and install oars on the hot air balloon, just like a steam engine would drive a paddle wheel, so that even if it goes against the wind, it's not impossible."

“.............”

Well, once the idea is opened, these researchers immediately think like a spring, some people are quite reliable, such as making large fans, and the propellers on airplanes in later generations are not "large fans".

But some people are a little whimsical, such as installing a steam engine in a hot air balloon.......... Not to mention the power of today's steam engine, the volume of the steam engine and the weight of the whole set of equipment alone are not something that a hot air balloon can bear.

Li Hongfei couldn't dampen everyone's enthusiasm, so he could only say with a smile: "Everyone has a good idea, but we must not be too ambitious, we can start with the simplest first, such as finding a way to control the direction of flight first, and then find a way to increase the speed." Of course, the premise is to ensure the load capacity of the airship, don't give me the whole guy who is lower than the carrying capacity of a hot air balloon at that time, that kind of thing, don't talk about me, even the brothers of the Air Force, will not buy it. ”

So far, Li Hongfei has made a clear positioning for the airship, first of all, it must exceed the existing hot air balloon in terms of carrying capacity.

The second is the sense of direction of the airship, which must not be like a hot air balloon, with an error of more than ten miles.

The last is speed, because the airship is the same as the hot air balloon, it can rely on the wind to fly, speed is not the most important thing for the airship, only the load capacity and accurate sense of direction are the foundation of the airship to achieve military use.

"Yo! It's really lively here, Zuo Xiang, the generals of the Feitian Army (another name for the Air Force) are here, I heard that yesterday Guo Zi flew from Majiazhuang to the military capital in less than two hours, it is majestic! ”

Just as everyone was discussing, a crisp voice suddenly came from outside the hall.

"What are you doing?" Li Hongfei looked at the person who came and asked subconsciously.

"Isn't this the place where the instructor will be stationed in the future? As a teacher, why can't I come? The visitor retorted.

The person who came was none other than Qi Hongying, the instructor and division commander who was just appointed by the Ministry of National Defense yesterday.

"Uh.......... You're here, what about Chen Yuanyuan? Li Hongfei asked.

During this time, Qi Hongying has been with Chen Yuanyuan, and now that Qi Hongying has come to Majiazhuang, Li Hongfei's first thought is that Chen Yuanyuan has also come over.

"Master Li, when did this place become the residence of the tutor?" Guo Sheng suddenly asked.

He didn't think as far as Li Hongfei thought, but he felt bad at the first time, isn't this the station of the Air Force and special forces?

Originally, this area was also empty, and it didn't matter if there were 10,000 or 20,000 troops, but Guo Sheng was reluctant to give up the good things of the weapons research institute, and suddenly stationed a mentor, which meant that someone was competing with him for equipment.

The key is that the one who grabbed the equipment was still the previous boss, and Guo Sheng could grab it?

"This........ The old man still has something to do, so I'll go back to the institute first. Song Yingxing saw that the atmosphere was not right, and decisively led the team to flash people.

It is inconvenient for him to be involved in the affairs of the military.

After Song Yingxing and other scientific researchers left, Li Hongfei said to Guo Sheng: "The matter of the relocation of the air force station was only recently decided, and after the backbone of the instructors and instructors are stationed in Majiazhuang, except for the special forces to assist in stationing in Majiazhuang, all members of the air force will be moved to the new base for training. ”

"Why? Do you think that our Air Force is not capable of guarding the Weapons Research Institute? Guo Sheng also lost his temper.

I thought it was just one more benefit, but I didn't expect it to replace myself, the dignified Air Force, being thrown around like a rag, and anyone would have a temper.

"The Air Force is a new type of troops, and it must ensure sufficient secrecy, it is too close to the capital, and your training often has to fly in the sky, and under the crowd of people, it is difficult to guarantee that it will not be discovered by enemy spies, for the sake of secrecy, you can only change a new training ground." Li Hongfei explained.

Hot air balloons have been applied to artillery units, even if they are discovered by spies, there is not much loss, after all, wherever there are garrisons with heavy artillery units, there are hot air balloon troops, but if even the airship is discovered by the spies, in order to obtain the secret of the airship, it is difficult to guarantee that no one will take risks.

For the sake of the security of the weapons research institute, Li Hongfei will not let the air force units stay here for a long time.

"Xiao Guozi, don't be discouraged, once this weapon research institute comes out with good equipment, my sister will definitely notify you as soon as possible to come and have a good time." Qi Hongying said with a smile.

In the past, Guo Sheng was Li Hongfei's descendant troops, and any new weapons that appeared in Suzhou Heavy Industry were delivered to Guo Sheng's troops as soon as possible, and even grenades were the first to be installed by Guo Sheng's army.

Qi Hongying still remembers that in order to get a batch of grenades, she ran from Chongming Island to Baoshan, and then from Baoshan to Suzhou, and finally took Chen Yuanyuan as a lobbyist, so she finally took 5,000 grenades in Zhenjiang.

Now that the instructor has squeezed Guo Sheng's troops away and monopolized the resources of the Weapons Research Institute, Qi Hongying can not be surprised.

"That's right! You haven't answered my question yet! Did Chen Yuanyuan also come along? "Li Hongfei didn't have a good airway.

The woman in front of her is simply the owner of the dyeing workshop when she gives some color, and every time she meets her, it will not be a good thing, in one sentence, that is: I owe her in my previous life.

"Why, you haven't been home all night, and you haven't even sent someone to carry a letter, so Sister Yuanyuan shouldn't worry about you?" Qi Hongying responded.

In the past, although Li Hongfei often worked late at night, at least he could go home, even if he had something to do, he would send someone to bring a letter to his family, but now it is good, the work is not as busy as before, but people can't find it directly.

"You....... I won't tell you this, I'll ask you, as a Ming soldier, don't you know that this is a military powerhouse, how can you casually bring ordinary people here? Li Hongfei said angrily.

"Who said I brought someone here? Knowing that even if Sister Yuanyuan comes, she can only wait near the dock, will I do such a thankless job? Qi Hongying didn't have a good air.

"Forehead........ You really didn't bring it in? Then you ........ just now" Li Hongfei looked embarrassed with a capital letter.

"What happened just now? As soon as you saw me, you thought of Sister Yuanyuan, what does it matter to me? Qi Hongying said.

"Adults don't want to be their daughter-in-law, don't you still want you to be successful?" Guo Sheng's resentment has not dissipated at this moment, and his mouth is a full-screen mockery.

"Shut up!"

"Shut up........."

Sure enough, Li Hongfei and Qi Hongying scolded Guo Sheng at the same time.

"Okay, you talk, I'll go with my brothers to pack our bags and prepare for the change of guard." Guo Sheng got up and left with his subordinates.

As soon as Guo Sheng left, only Li Hongfei and Qi Hongying were left in the entire hall.

"That.......... I'm sorry, maybe I'm too tired during this time, so I'm a little irritable. Li Hongfei was the first to admit his mistake.

Even Li Hongfei himself didn't know why he said this to Qi Hongying, perhaps to explain the other party's previous sentence of not being home all night.

"I don't know how you are, but Sister Yuanyuan has been a lot haggard because of your deliberate avoidance in the past two days. If that's the price to pay for supreme power, then I want to ask you, is it worth it? Qi Hongying asked.

"What is this! This is my private matter, what does it have to do with the power in my hands? Li Hongfei said.

"Does it really matter? I don't think you even knew it! Now you give me the same feeling as when the Holy Lord summoned us after the victory of the Western Expedition. Qi Hongying said frankly.

Whether it is a lonely person, or the holy will is unpredictable, or the companion is like a tiger, it is all about the indifference and ruthlessness of those in power.

The supreme power makes them lose themselves, and while controlling power, they are also controlled by power, and they cannot have family affection, love, or even any weakness.

Because in the subconscious of these people, once their weaknesses are exposed, they will become the opponent's means of attack.

This is the self-defense mechanism of those in power, and today's Li Hongfei has also subconsciously opened this defense mechanism............
