Last time, I mentioned that after Emperor Chongzhen took the design drawings of the "treasure ship" and showed it to his brothers and fellow Taoists, he was out of control and decided to build a ship immediately.

Since everyone is the best of the "Jindan real people", their mental strength is strong, and they are far from imagining ordinary people, so after a little scan of the design drawings of these "sea ships", they can understand it in their hearts. In particular, Zhu Youxiao and the girls also silently cast the spells of "penetration" and "penetration" to deal with it.

After in-depth repeated disassembly, analysis, deduction, induction, and summary, everyone unanimously came to the conclusion that these design drawings are not "perfect" works, at least there is still a lot of room for change, and the comprehensive performance and use value of the "sea boat" designed in this way will be greatly improved.

The first thing to improve is the design and structure of the hull, if a large number of large thick iron plates are replaced by the "mortise and tenon structure" of the whole trunk or thick and straight resin, then the size of the "sea ship" can continue to expand ten times or even dozens or hundreds of times!

However, due to the limitations of iron-making technology at the time, this design was difficult to put into practice, unless the "doppelganger spell" was used to vigorously mine and use a large amount of steel! Of course, as far as the steel they obtained from the "Kunlun Ruins" last time they participated in the "Kunlun Trial" is concerned, they can also build several large iron ships together!

Secondly, on the "firepower configuration" of the "sea ship", all "smoothbore guns" can be converted into "rifled guns". In this way, with the advantages of smaller and lighter weight of the "rifled guns", but with longer range and higher accuracy, the number of "gunwales" can be doubled, and the intensity of fire can be greatly increased!

Third, after replacing the "smoothbore guns" with "rifled guns" has solved the problem of effective long-range firepower from "sea vessels," we can try to install two more "mortars" and "Lubanguns" on the bow and stern sides of the ships as medium- and short-range "firepower networks" to provide firepower assistance for the Ming army's beach-rushing landings in the future. At the same time, the soldiers of the naval division on the ship uniformly used "smoothbore guns" to fight, and no longer mixed and matched cold and hot weapons according to the queue of the original "new army" model.

Next, it is necessary to significantly improve the power system of the "sea vessel". In addition to the original use of "sails" propelled by the wind, it is also required to be equipped with a large "steamship mechanism" as a power source, that is, each "sea ship" has two large "propellers" on each side of the bottom under the bow and stern, and each side corresponds to a "steam engine". In addition, the "rudder" should also be divided into "front rudder" and "rear rudder" to control the driving state of the "sea vessel" at the same time, so as to ensure the safety of the "sea vessel" when it is fast against the wind and current!

In the end, after unanimous discussion, it was decided that the new "sea boat" was doubled in the original design size, that is, from the original "44 zhang long, 18 zhang wide, with a total of three layers" to 88 zhang long, 36 zhang wide, and a total of six floors. However, the height of each floor has been changed from nine feet to one zhang high.

At the same time, it is stipulated that the lowest layer is used to transport fuel, fresh water, and steamer organs; The second layer is loaded with guns, gunpowder, swords, bows and crossbows, spears, shields, armor and other ordnance materials; the third layer is filled with military supplies such as grain, clothing, preserved fruits, dried vegetables, and medicines; The fourth floor is the dormitory of the crew, handymen, and soldiers' families; The fifth floor is the dormitory of the "marines" and "firearmsmen" in the sailors; The sixth floor is the commander's office area and bedroom.

In this way, the frame design and functional demonstration of the large "sea vessel" are completed. However, after all, large "sea vessels" are not "steamship machines", and their complexity and material consumption far exceed the latter. Therefore, even if Zhu Youxiao personally went into battle and relied on the "doppelganger spell" to fight with the women, it took a whole day to build a large "sea boat", after all, the inside and outside of the ship board had to be repeatedly painted and oiled to prevent moths and water leakage.

However, according to the reminder of his master "Carpenter", Zhu Youxiao also drew some "special seals" similar to "talismans" at key positions on the hull in time with "magic ink" made of cinnabar, dog blood, hair ash and other materials, such as "water avoidance spell", "wind avoidance spell", "fire avoidance spell" and other supernatural powers.

However, on the "boiler" of the "steamer mechanism", there is usually a "fire sitting charm", and when some spells are cast simultaneously to activate it, the excess heat generated by the "boiler", that is, the "chimney", can be imprisoned for a certain period of time, and only the high-temperature water vapor is allowed to push the piston to do work repeatedly.

The so-called "steamer mechanism" is actually the early "steam engine". The thermal efficiency of the early "steam locomotive" is very low, because only part of the heat generated by the combustion of the fuel in the boiler is converted into the heat energy of steam, and the rest is wasted, so the thermal efficiency is generally 50%~80%.

And when the "steam" works in the "steam turbine", it will be affected by factors such as temperature, pressure, friction, and the tightness of the "steam turbine", so that the mechanical efficiency of the "steam turbine" is generally only 10%~15%, but in the process of transmitting power from the turbine to the wheel circumference, its mechanical efficiency is as high as 80%~95%!

The "steam locomotive" of later generations can be divided into the following categories according to the nature of the work and its utilization: first, the "single expansion locomotive", that is, the high-temperature "steam" expands in the "cylinder", and is directly discharged into the surrounding environment when the "steam turbine" is pushed by the "piston" to do the round-trip movement. The locomotive has a simple structure and a wide range of applications.

Second, the "reexpansion locomotive", that is, the high-temperature "steam" expands in one or a pair of "cylinders", especially the "high-pressure cylinder", and then enters another or a pair of "cylinders", that is, "low-pressure cylinders" for reexpansion to push the "pistons" of the "steam turbine" to work, and finally discharges into the outside atmosphere. Although the thermal efficiency of this "steam turbine" has been greatly improved, the structure is more complex and less used, because its working principle is close to the "cylinder" of the "diesel locomotive".

Third, the "condensing locomotive", that is, the "exhaust gas" that becomes after the "high-temperature steam" pushes the "piston" of the "steam turbine" into work, is condensed into water in the "condenser" installed at the tail of the boiler by a special method, and then pumped into the boiler for reuse, and the lost water is replenished by the water in the boiler.

The structure of this "steam locomotive" is very complex, and it is mostly used in water-scarce areas, such as desert grasslands, Gobi Plateau, snowy ice fields and other environments.

Fourth, "saturated steam locomotives" and "superheated steam locomotives". Since the "locomotive" uses the "superheater" to increase the steam temperature, this greatly improves the thermal efficiency of the "steam engine", and the "saturated steam locomotive" is transformed into a "superheated steam locomotive", which can greatly improve the power and power of the "hot wheel locomotive"!

Therefore, if there is no special technology to "insulate" the "boiler" from the outside world, the maximum thermal efficiency of the "steam locomotive" is only 8%~9%, and the "boiler" is not turned off when the station is stopped, and the "boiler" is not turned off when the locomotive is maintained and stayed, and fuel is still consumed, resulting in the actual thermal efficiency of only 5%~7%.

However, Zhu Youxiao is not a so-called "scientist" in the mortal world in later generations, but a "Jindan real person" among the "cultivators", and it is indeed easy to seal the "boiler" with "talismans" to prevent heat from dissipating heat to the outside world, so the thermal efficiency of the "boiler" is increased to 85%, because the "piston" and "chimney" need to dissipate heat.

In this way, in the process of power transmission from the "steam engine" to the "axle", after deducting the influence of "friction", "gravity", air "resistance" and other factors, the mechanical efficiency of the later "steam locomotive" can also be increased from 6% to more than 60%, which is simply higher than the work efficiency of the "internal combustion engine" in the later generations!

The so-called "internal combustion engine" generally refers to the "piston engine" that was invented in later generations. There are mainly "gasoline engines" and "diesel engines", and there is no "kerosene engine" for the time being, because "kerosene" is inferior to "gasoline" and "diesel" in terms of stability and cost performance, so kerosene is used as power fuel in later generations.

The power of the "internal combustion engine" is large and small, and the ships and aircraft with the highest power have tens of thousands of "horsepower", and the minimum power is only less than one "horsepower". In later international standards, one horsepower was equivalent to 735.5 watts, or 0.7355 kilowatts. But this "concept" did not appear in the late Ming Dynasty.

However, when people in later generations used "steam engines", they usually used "steam turbines" for work, and they were mainly used for large ships and power stations. In general, a "steam engine" of the same power is much larger than an "internal combustion engine". And when the appearance and volume are the same, the power of the "steam engine" is much smaller than that of the "internal combustion engine". However, due to the fact that there was no "petrochemical" in later generations in the late Ming Dynasty, it is of course impossible for there to be an "internal combustion engine"!

However, at this time, there were many improved versions of "steam locomotives" and "steam engine ships" in the Ming Dynasty, which were called "steamboat locomotives" and "steamboat machines", which were referred to as "trains" and "ships" respectively. Although these ingenious "mysterious things" can be called "strange tricks", they all play a pivotal role in solving various transportation problems at home and abroad in the Ming Dynasty, after all, their work efficiency is really subverting people's imagination!
