"Why can't you see the paddle wheel on this boat?" Polina looked around and asked.

"Paddle wheel? How could we use such a backward design?" Joseph said disdainfully.

"If there is no paddle wheel, how do you pull the water? Do you use reciprocating levers to paddle?" Polina said, "If this is the case, it seems to be very beautiful."

"This...Paulina, maybe you should also receive a little education in mathematics and physics." Joseph shook his head, "Our boat uses a propeller. This is a kind of underwater propulsion equipment. It is much higher than the paddle wheel, and ordinary wind and waves will not let it get out of the water, and the enemy's artillery can't hit it—British's stupid paddle wheel, I don't know where to go!"

"Professor Bonaparte's propeller is indeed a great design." Fulton said sincerely on the side, "I really did not expect that there would be such a way of propulsion, and the efficiency is indeed much higher than that of the paddle wheel. "

"In fact, it is very simple to think of." Joseph immediately installed the big tail wolf. "In fact, this design was first derived from the water turbine in the Zeus plan. The design of the water turbine was actually developed from the windmill. Fu. Mr. Dunn, you know that many processes in physics are reversible. Since a windmill can be blown by the wind, the windmill that rotates in the opposite direction can blow out the wind; the water turbine can be impacted and rotated by water, then it rotates in the opposite direction. The water turbine can push the water flow. So you see, this is not a particularly difficult design. On the contrary, the problem of water seepage in the propeller shaft is more complicated to solve."

A triumphant smile suddenly appeared on Fulton's face. This problem was solved with the joint efforts of him and several other engineers. Of course, it has not been completely solved. The water seepage still needs to be water seepage, but the speed of the water seepage has been controlled to a certain extent, and a small pump can completely solve the problem.

Fulton took a few people to the flat deck at the bow. There are seats and parasols. Champagne is still on the table.

"Professor, as long as you give an order, the sea trial can begin." Fulton said.

"Okay." Joseph stood at the bow of the boat with great spirits, waved his hand, "Go forward! Go forward! Our goal is the stars and the sea!"

So the boat shook slightly, and then slowly left the dock. It first sailed westward along the current for a while, and quickly passed several other ships encountered on the road, then turned around and sailed eastward against the current.

"How fast can this boat go?" Polina asked.

"The'Stupid' can theoretically run to around thirteen quarters." Fulton replied.

"What? How could this ship have such a strange name?" Polina was surprised.

Fulton glanced at Joseph, and Joseph was expressionless. He would not say that he took the name of this strange flower, and he took this name entirely because he mentioned Fulton's steamship in a text he learned in his previous life, and that ship was called by people. As "Fulton's fool", but it was a huge success.

Considering that some of the traditional cultures learned in the great eastern countries in the previous life mentioned that it is easy for children to take a low name to raise them, and considering that "Fulton's Stupid" is not the first steamship, it has become The first steamship that was a huge success, Joseph felt that this traditional superstition might still be true... so he gave the ship the weird name "Stupid".

But Joseph would never admit that he had decided on this name. So when Polina asked this question, he said nothing.

"Ah, on this question, it's... that's the case... We kept arguing when we were naming it, and in the end... we decided to go through the dictionary to make a decision, and then we came up with the word. But everyone has already It’s decided. No matter what you dig out, you can use whatever you want. For men, you should speak credibly, and use whatever word you dig out. Then use this word, so it’s settled." Fulton The reason for the present editor explained that at first he was stumbling, but the more he said later, he almost believed it himself, um, that’s how it was.

At this time, the ship had turned around and started to accelerate against the current. In a countercurrent state, the advantages of this ship become more obvious. It spit thick smoke, quickly left one after another sailing boats behind, and soon returned to the place of departure.

"This boat is so fast. Is this their highest speed?" Polina asked again.

"No, today is a formal trial. As for the high-speed sailing experiment, it is not going on today." Joseph replied.

In fact, in the "informal sea trial", high-speed sailing tests have been carried out. However, high-speed testing needs to increase the boiler pressure, and increasing the boiler pressure will increase the risk of boiler explosion. Therefore, of course such an experiment cannot be carried out today.

This successful experiment came very timely, because Ireland has reached the most critical moment.

Recently the Irish Independence Army has just repelled a new round of sweeps by the British. And in the anti-sweeping campaign, he has achieved great success. In this counter-attack, the Irish Independence Army demonstrated its strong attack capability for the first time. They used a special explosive projectile in the battle, which made almost all the defense facilities equipped by the British for those military stations become effective. The furnishings.

This so-called "explosive ejector" is actually the "flying thunder cannon" used by a certain Eastern army in later generations.

Use a large iron tube with propellant inside, and then stuff it into an explosive bag about the same diameter as the caliber, and then ignite it to project the explosive bag nearly two hundred meters.

The explosive package of about ten kilograms fired by this thing is powerful, and the wall of the British military station is like paper in front of it. Of course, the range of this thing is limited. If it is daytime, the defender can effectively prevent the installation of the Irish Independence Army’s "explosive projectile" through a salvo of rifles. (This thing needs to dig a hole in the soil, then set up the launch tube inside and adjust the angle.)

But the cunning Irish would use the cover of the night to quietly place and disguise the "explosive projectile" near the wall of the British military station at night. At dawn, it made an offensive appearance, attracted the British defenders to the wall here, and then ignited the "dynamite projectile" to let the rushing British troops fly into the sky with the wall.

Relying on this thing, the Irishman who turned over quickly seized several vital military stations at a speed exceeding the British estimate, and even approached Dublin for a while. But the British still maintained a very strong mobile force in the rear, so the British army immediately mobilized the reserve team to launch a counterattack.

The First Division of the Irish Independence Army had an encounter with a thousand British troops who came to rescue near a military station more than 60 kilometers away from Dublin. The battle ended with the retreat of the Irish Independence Army, which had a strength of about 1,000 troops, but the casualties of the two sides in this battle were not much different. The British army suffered more than 200 casualties, while the Irish casualties were probably higher than this, but it would not exceed 400. This result naturally shocked the British.

Although the British troops who fought with the Irish in this battle were mainly recruits, they were regular troops after all, and various weapons were more suitable for frontal combat. And they also have cavalry. When the Irish retreat, these cavalry should be able to bring huge damage to the Irish. But even so, they didn't get much advantage in encounters with similar numbers. Especially the cavalry. When they were pursuing the Irish, they fell into the ambush of the Irish broadsword mine. One guy lost almost a hundred people. This result made the British truly feel the growth of the Irish rebels.

In the base area, the Irish Independence Army, with the cooperation of the rebels, constantly attacked the "security forces", and the British army, who accidentally kept the distance from the friendly army, constantly used black guns to lure the British army to pursue. , And then used broad swords to ambush their tricks to bully the British and the black dogs. As a result, although there were no large-scale battles on the base area, the daily losses of the British army and the "security forces" were not small.

If it was before, the British should retreat at this time. But this time, the British just gritted their teeth and continued to support. Because the British discovered that the weapons and ammunition in the hands of the Irish rebels began to gradually become unavailable. Especially in recent days ~lightnovelpub.net~ there have been few reports of troops being attacked by broadsword mines. There are also fewer reports of the use of flying thunder cannons by the Irish Independence Army. This shows that there are not many French goods in their hands.

"I know that no matter whether it is in the non-security zone or in the public security zone, our army has lost a lot. But this time, we have to grit our teeth and persevere. Now the strength of the enemy army is obviously fading as long as we persist. In a while, they will be over. Now it depends on who is more able to persevere. And the tougher side can win the whole of Ireland." The Duke of Norfolk treated his subordinates in the beautifully decorated conference room of the Government House. Say.

"Now, our struggle has reached a critical moment. We must persevere. Perseverance is victory. We have a shortage of materials, especially weapons. This is indeed a problem, but there is no new weapon sent by French comrades. We can’t fight the enemy, can we not defend our base areas and the people in the base areas? Now, we must save weapons on the one hand, and improve the efficiency of the use of weapons on the other, so that every bullet can destroy an enemy On the other hand, we must use captured weapons as much as possible and use self-made weapons to attack the enemy.

Now we are difficult, but the enemy is equally difficult. As long as we hold on, we can see the dawn of victory..." In the swamp camp, Russell was holding his trousers and barefoot, saying this to the Independence Army soldiers surrounding him.
