Qin Tianmin looked like he wanted to speak and stopped, pulled Lu Hong to the side, and said in a heartfelt tone: "Tang Wenjin of the water master is coming to you again, if you make up your mind to follow Huang Gong, and then you have too close contacts with people from the Huai family, I am afraid that it will affect the future, Brother Lu, this kind of thing is not sloppy!" ”

Lu Hong looked at this guy, if he wanted to mix in the officialdom, this is really good, above the officialdom, this kind of wall-to-wall behavior is the most taboo...... However, I can't always follow along, I have already foreseen a naval battle, and there is no harm in being familiar with the navy!

So after thinking about it, he smiled and said: "Brother Qin, thank you for reminding, there is another reason for this matter, I have already planned, the future development of you and me, if my plan can be successful, it is really quite related to this Beiyang Naval Division...... In that case, it wouldn't hurt to get to know more people from the water master! ”

Qin Tianmin was stunned for a moment, his idea of being promoted to an official and making a fortune was still on the routine of donating officials, and he was a little surprised to hear Lu Hong say that he had a plan, but he had seen Lu Hong's ability, and he had heard him say that he had a plan, but he didn't say more, and the two of them came to the door to see Tang Wenjin together.

When he arrived at the door, Lu Hong found that Tang Wenjin was obviously not the only one who came, there was also a young officer who was slightly older than him and had a well-fashioned mustache beside him, and he observed at a glance that the sleeve of this officer's blue five-cloud suit was a two-day wide gold bar, according to the information he learned on the Pingyuan ship for two days on the ship, this should be from the fourth grade, or the fourth grade of the martial arts, compared to the Pingyuan ship with Li He, there is also a difference of one level, and this young officer also has two low-level officers with a gold bar behind him, Looks like a cronie.

Seeing Lu Hong come out, Tang Wenjin had already walked over happily, pointing to the young officer with the two medium-wide gold bars and said with a smile: "Brother Lu, let me introduce you, this is the secretary of our Beiyang European and American Scholars Association, Du Si Cai Tinggan, he is a torpedo expert, he just arrived in Tianjin Wei yesterday, and mentioned the Howell torpedo you mentioned in the morning chat, but he didn't believe it at all, so I pulled him to confront you face to face!" ”

Cai Tinggan...... Lu Hong remembered this name all of a sudden, and listened to Tang Wenjin's introduction to this position, the fourth-rank Dusi, which was already in the ranks of senior officers, and this current position, Tang Wenjin did not introduce it, and Lu Hong also knew that the Fulong torpedo boat that he had laughed at earlier and was used to deliver lychees to the old woman of the Empress Dowager Cixi, isn't this the pipe belt! Thinking of this, he couldn't help but think of it with a bad taste, this person who appeared in Tianjin Wei couldn't be the Shenma Guangdong fruit again......

However, he didn't intend to ask such a gossip question, and immediately showed a hospitable face, "Lord Cai, I have been looking up for a long time, Brother Tang is too persistent in this matter, this Howell torpedo is a weapon produced by the United States, if it is this power, and the black-headed torpedo used by my Daqing Dynasty, it should also have a strength!" ”

Cai Tinggan is a child in the United States, especially good at English, and even can translate Chinese ancient books in English grammar, if he has the opportunity to read domestic English newspapers from time to time, but he has never heard of the Howell torpedo that Lu Hong said, so when he had dinner with Tang Wen earlier, he heard this guy mention three or two sentences, saying that the combat effectiveness of this torpedo is better than that of the German black-headed torpedo that the Beiyang Naval Division is familiar with. I can't help but have the urge to come and get to know one or two.

Cai Tinggan was obviously not satisfied with this simple explanation, Tang Wenjin only cared about artillery, so the words he heard during the chat were not at all the point, so he immediately asked: "Lu Gongzi, listen to Tang Wenjin, you have traveled to Europe, you must have seen this type of torpedo, can you explain to us what are the advantages of Howell torpedoes!" ”

This Cai Tinggan's question obviously meant not to believe, Lu Hong was slightly older than Tang Wenjin at this age, even if he was a study tour of Taixi, how many opportunities could he have to learn about this kind of confidential news, at most, he had heard a little bit of fur, so he took it out to show off, so he threw out a very difficult question at once, in his opinion, if he was not a professional, he would definitely not be able to answer it easily!

Looking at this guy's slightly smiling face and the two elegant mustaches, Lu Hong secretly raised his middle finger, as for Tang Wenjin, who was watching the excitement next to him, Lu Hong really wanted to kick this guy's ass, but these two guys seem to have some use value, so we might as well show our knowledge......

However, this speech is very skillful, you ask us like a teacher, how can this be, obviously I am teaching you, he smiled in his belly, and asked: "Cai Dusi, I think you are good at torpedo launch, I don't know, do you feel that the best launch distance of 100 meters for black-headed torpedoes is too short?" If a black-headed torpedo is fired at a limit distance of 500 meters, can you be sure where the damn torpedo will go? ”

Lu Hong's words pointed directly to the shortcomings of torpedoes in this era, which immediately made Cai Tinggan's expression, who was interested in testing him just now, immediately become serious, and after pondering for a moment, he immediately shook his head, "Lu Gongzi seems to be really familiar with this torpedo tactic...... But I don't know if you can solve the two fatal problems of black-headed torpedoes! ”

Lu Hong naturally understands the technical problems of torpedoes in this era, torpedoes appeared for almost 30 years, until the emergence of white-headed torpedoes and black-headed torpedoes, which made this kind of underwater weapon really combat, but the weapons of war are always the mutual upgrade of spear and shield, and now, with the emergence of machine guns and rapid-fire guns, it is necessary to approach to a distance of 120 meters to have a reliable and accurate torpedo, which makes the combat effectiveness worse and worse.

A big part of this is due to the difficulty of torpedo linear navigation and the difficulty of stable operation of the depth machine, the 14-inch black-headed torpedo equipped by the Beiyang Navy has some improvement compared with the most white-headed torpedoes purchased by the British Royal Navy, however, the black-headed and white-headed torpedoes of this era are powered by compressed air driven engines, and the air is discharged from the compression cylinder barrel to generate kinetic energy.

The obvious problem, that is, the compressed air tank will quickly become lighter, so, this has led to a serious problem of torpedoes in this era, the problem of top-heavy after launch will be obvious after launch, although there is a depth of machine control, but inevitably, a slightly longer range of launches, this powerful weapon has a completely unpredictable assault trajectory!

Therefore, the maximum range of 500 meters of black-headed torpedoes, the recommended launch distance is only 100 meters, to achieve a good hit, it has to be close to within 50 meters, and in this era of the Royal Navy for rapid-fire guns and machine guns hit calculation, 1500 meters of artillery hit rate of 10%, and close to 500 meters, the hit has been as high as 80%, below the distance of 400 meters, the battleship has reached 100% of each round of fire, in this case, To attack the enemy at a distance of 100 meters in a wooden unprotected torpedo boat is almost like sending you to death!

In terms of torpedo navigation, the Howell torpedo made by the Americans has a very simple device, and a flywheel shaft is transversely placed in the torpedo, which can transmit the deflection torque to the mine body, so that the torpedo course is deflected, and the other transverse pendulum detects this deflection and directly drives the rudder to deflect to produce a proper correcting moment to correct the deflection of the torpedo.

But for the era when gyroscopes never appeared, the Howell torpedo, which has this advantage, has been unable to enter the American market for the past 20 years, mainly because the Howell torpedo has a straight-line navigation distance of more than 600 meters, which is close to the maximum range of the torpedo......

However, Cai Tinggan asked Lu Hong to solve this problem, although Lu Hong understood the basic principle of the gyroscope and could even draw the intention, but to modify the black-headed torpedo, this is really a very challenging problem.
