Chapter 918 Ironwood
Although Captain Bacca's ships and crew sailors used for combat were all killed by the Spanish Caribbean fleet. However, the small industrial foundation of his hiding place was still there. Now, after the alliance with Zhang Fan's team, Katerina and Captain Hook's pirate regiment, it should be restored quickly. Moreover, the alliance is now sufficient funds, and the business activity plan is also being launched under the plans of Shu Yao and Captain Stoke.
In order to conceal those Carac large sailboats, Captain Bacca's hiding dock drove enough horsepower to transform the six sailboats. All the complicated decorations related to Spain on the ship were removed, as well as the useless tail building for navigation and transportation loading, repainted, and replaced the ship's head. These seized large Spanish sailboats will be renovated in the next month or two and set sail again.
The most important thing for Akan was to immediately remove the two spiral propulsion systems of the "Sunset". Although the two sets of dark green prop props were still very primitive, they were immediately merged by the "Shengren's Paddle Rod" paddle boat.

At this time, the "Saint Sword" also changed a lot. The four masts turned into three, and the mast at the front fell into a short bow short splint, as if the bow was like a mighty one-horned horn. Between the foremast and the splint, there were two diagonal spinnakers hanging on the rear mast, and the longitudinal inclined sails were also hung on the rear mast.
Interestingly, these sailing tools, including the spinnaker on the bow, have changed and returned to the Chinese pine sail style. The main mast and the main mast have become integrated trapezoidal sails with wide upper and narrow lower bottoms. The windward surface is very large, just like a piece of dorsal fin picked from the back of a dragon. The spinnaker on the foremast and the longitudinal inclined pine sails of the rear mast are like open arc fins, with bone spurs diagonally extending from the sail surface. It is also like an open Chinese folding fan, which looks simple and ostentatious.
Such a sail is hung on the mast, and the sail surface is reinforced by a horizontal bamboo pole. It is not only firm and solid, but also uses few cables, unlike the cable pulley system that is as dense as a spider web on a European sailboat. It is also easy to collect sails. As long as you loosen the cable with a winch, it is like closing a folding fan, and you can easily put the sail away.
The hull of the ‘Saint-Sacred Vase’ has also undergone some changes, forming a smooth streamlined structure. The widest position is at the back of the middle, forming a long water droplet shape from the sharp and narrow bow. Such a streamlined hull is very different from the shape of the European hull, and is more rich in the characteristics of an ancient Chinese ship. In terms of ship shape design, although China and Europe use bionic principles to design the hull as streamlined, but the object of imitation is different. Europeans imitate fish, while China imitates water birds.
In this way, the widest part of the European hull is in the front of the middle, while the widest part of the Chinese hull is in the back of the middle. Later fluid mechanics research proved that China's practice was more scientific, because ordinary ships are not submarines, and do not swim underwater like fish, but like water birds, such as ducks and geese, rowing between water and air. After realizing this, Western ships later placed the widest part behind the middle like Chinese ships.
After replacing the propeller propulsion system, although it was still man-powered, the speed and load of the "Saint Vane" were greatly improved, and the hull weight was greatly reduced. This also allowed Captain Baka to see the hope of his new flagship. Moreover, Akan also promised to help him build a fleet of ten new 300-ton armored ships that were no less than ten years! Of course, he must also be loyal to Baron Shifan for ten years, and Baron Shifan owns half of the fleet's shares and command power.
Captain Stoke's work was a little harder to do. He originally planned to lead Zhang Fan's team. After finding Hawkins and Drake's fleet, he left everyone and returned to Africa to live in seclusion. However, after Zhang Fan and the Book Fairy, and the "Caribbean Alliance" seemed to have lit up his ambition to travel to the Atlantic Ocean, Stoke decided to join the Baron's fleet. But he was only willing to engage in some commercial activities and non-grafting naval battles. Perhaps he was no longer willing to stain the blood of innocent people on his hands. This was exactly in line with Zhang Fan's requirements, a loyal, upright and trustworthy leader of a commercial fleet.
Zhang Fan's team handed over the management rights of six Carac sailboats, several escort three-masted sailboats, as well as the management rights of the Port of St. Nicholas. In terms of commercial operations, he and Captain Baccar are both good players. And now the entire Caribbean knows that Captain Baccar's pirate group was defeated by the Spanish fleet, so he happened to take this opportunity to switch to business and transportation, and no one would doubt it.
The Book Fairy provided information on the very useful propeller transmission mechanism for Captain Akan and Baka. There are detailed drawings of sealed water lubricated bearings made of ironwood at the connection of the hull. The ironwood wood is very hard and corrosion-resistant, and can produce a kind of mucus in the presence of water, which greatly reduces the friction coefficient of the friction surface and realizes the role of self-lubricating. Therefore, ironwood is of great use in shipbuilding.
The stern shaft pipe part of the ship connects different environments inside and outside the ship, and titanium wood is suitable for installation in the part that contacts seawater. While supporting the stern shaft well, it reduces the requirements for the sealing of the shaft on one side of the seawater. You should know that even modern ships still use sealed bearings made of titanium wood. This kind of tree is everywhere on Haiti Island with high mountains and dense forests.
Ironwood bearings are not made of a complete piece of material, but are composed of upper and lower bearing pads made of ironwood strips. Several relatively thin copper strips will be installed between the wooden strips, which are fixed by the clamping of the copper strips to prevent the iron pear strips from moving. The texture of the upper bearing pad is parallel to the tail axis. The texture of the lower bearing pad is perpendicular to the tail axis and points to the center of the shaft.
Such manufacturing technology requirements are not very high, but this kind of sealed bearing was not invented in this era. Once you know the key to this technology, you can do it with the technology technology of this era. Shu Yao and Akan only promote this later civilization technology in advance. Just like Shu Yao taught ancient Chinese people that iron smelting and papermaking, the difficulty was even lower than teaching iron smelting and papermaking technology.
