The Ship Research Institute mainly studies stronger, more suitable for ocean-going ships, and at the same time, will also make some adjustments to the Spanish galleon itself, for example, how to save manpower the most, and at the same time, under the premise of the same tonnage, so that the utilization rate of sails is higher, and people's efficiency will be higher, these are a systematic engineering, which needs to be studied for a long time.

At present, intermittent results have been achieved, for example, the application of some power tools on ships, the current generators of the Dinghai Navy, are large-scale, the smallest is the size of three or four houses, such a huge motor, can be installed on the ship, but has occupied most of the space on the ship, so it is not desirable.

However, in addition to generators, there are batteries, Zhao Xin may not know more advanced batteries, for example, nickel-cadmium batteries, lithium batteries, but the simplest, lead-acid batteries, or understand, this kind of most basic battery, in fact, appeared as early as BC, but the utilization rate is not so high.

Knowing the positive and negative electrodes of the battery, the electrolyte, the rest is to try step by step to find out the highest power, with the help of the card system and researchers, simple lead-acid batteries have appeared, and at the same time, they have begun to gradually improve, and some battery packs similar to the batteries of later generations have begun to appear, and electricity can be widely used even without generators.

Spanish sailing ships have sails that are larger than the hull, and it is with the help of these sails that the wind that can be seen everywhere in nature can be converted into power, propelling the sailboat to move forward without stopping, with a speed of more than 12 knots.

Cheng also sailing ship, defeat also sailing ship, the force surface of the sailboat is huge, when the storm comes, or when the wind is too strong, it is not easy to adjust, the sailors on the sailboat, most of them require Kong Wu to be powerful, the reason is that when the wind comes, can flexibly use the sail.

Manpower always has an end, a person's strength, even if it is as strong as Sun Ji, that is, the power of a thousand catties, in the face of the great power of nature, they can do quite limited, in the storm, the captain can only choose the most suitable, but also the most labor-saving, often waste a lot of things.

It's not the same with electricity, as long as it's still there, you can work endlessly, maybe it's impossible to replace sailors for a long time, but at critical moments, it can be a killer feature.

With this prerequisite, it has become inevitable that electricity will be carried on Spanish sailboats, and in the same way, all places that require labor, such as pumping systems, control systems, and even auxiliary oars, can use electricity, even if the auxiliary system is quite slight, and can only push a very small propeller, and at some critical moments, these extra power may turn a ship in danger into safety.

In the institute, there is a big project, that is, the use of various labor-saving electrical appliances on the sailboat, after the system and integration, the manpower on the sailboat can be reduced by more than 60%, which is a huge benefit for the sailboat.

The most lacking thing in the Dinghai Navy is qualified sailors, even if the Dinghai Navy is now, it has spent a lot of effort to continuously train all kinds of sailors, but in the face of the continuous expansion of the ocean-going transportation force of the entire Dinghai Navy, such manpower is still too far behind, there are many ships, after they have been built, in the dock, waiting for people to maneuver, some ships that have just been launched for a year or two, because of the cost, have been mothballed, or even concentrated.

If a fully loaded ship reduces 40% of the personnel, then it means that the manpower of a ship can open two ships, which is almost a doubling of the capacity.

As for the production efficiency, the popularization of various advanced machinery, the standardization of various production steps, and even the assembly line has been introduced into the process of ship production, and there is no problem at all with the simple explosion of output, if there are enough personnel to operate, the Dinghai Navy can more than double the number of the current ocean-going fleet at any time.

However, people are the most lacking, the use of all kinds of electrical appliances, the use of some labor-saving equipment, and even in some research institutes, how to reduce the size of the steam engine, the small steam engine, the application of the ship's plan, if these are fully implemented, not only the personnel on the ship will be reduced a lot, and even the speed of the ship will be increased.

However, in terms of how to change, the development of the Spanish galleon has reached the extreme, this is a very suitable ship as a warship, and as a ship for ocean transportation, but it is not suitable for exploration, not suitable for charting.

Even if you have a certain understanding of the shape of the Pacific Ocean and the location of the North American continent and the Asian continent, you can even find the Bering Strait if you let the ships go north along the coastline, and there is no doubt how wide the Bering Strait is, and after crossing it, it will be the American continent.

It is a pity that the harsh climate in the high latitude area is the biggest constraint, Zhao Xin can't, and it is impossible to choose such a road, then, in Hokkaido, gradually to the north, in these island-dense places, to search, step by step using island hopping tactics to search, after stabilizing an area, continue to go down, after the chart is perfected, and then relay, it has become an inevitable method.

In this case, the Spanish sailing ship was a little insufficient, and his speed was relatively slow.

With the exhaustive method, with the method of island hopping, step by step, efficiency is the first, with the island as a circular motion, it is almost certain that you can explore the nautical chart around the island, and find the way forward, but this method is too slow.

If you still use a Spanish sailboat, it is too inefficient, and the difference in speed is a key problem, although it carries a lot of cargo.

When it comes to ocean exploration, cargo capacity is the least of a concern, as long as there is enough speed.

In the world, among the non-powered ships, which ship is the fastest, Zhao Xin can answer this unmistakably, that is, the clipper.

Hollow bows, more and larger sails, less superstructure for increased stability, a more narrow arrangement, and some of the hulls under the water allow the ship to chisel the water like a knife and axe, and the title of clipper also benefits from such a nautical state.

In Spain, the average speed can only be 6 to 8 knots, when sailing on most of the sea, the clipper, can sail at an average speed of 12 to 14 knots, almost twice as fast, after the middle of the 19th century, through the Atlantic race, the clipper is the undisputed champion, an average of 13 days across the Atlantic, which was not possible before, but the clipper, can be easily achieved.

Although Zhao Xin has never seen a flying clipper, he has heard the name of the flying clipper countless times, and on the Internet, because of his military hobby, he has also seen many pictures, and he has also browsed the key points about the flying clipper.

After memories and enhanced memories, Zhao Xin drew a lot of drawings, and also put forward a few things to say about the clipping boat, a high proportion of the hull, reducing the superstructure, sailing as close to the water as possible, and most importantly, a hollow bow.

This is the key, only hollow, can make the specific gravity relatively low, under the telling, the bow will go up, not only can break the waves, but also reduce the force surface, reduce the resistance, this is the key to the clipping boat. The clipper, which is known as the strongest sailing ship in the sail era, and even in the power era of later generations, sailing around the world is basically a clipper boat. Even in the 21st century, under the premise that computer-aided design has reached its limit, with the help of human creativity and the help of computers, there is still no ship type that can surpass this kind of ship.

According to his memory, Zhao Xin drew some drawings on the drawings, which were seen in later generations and sailed around the world, because of the problem of memory and attention, these have been relatively blurred, but these have given researchers great inspiration, especially some key places, proportional hulls, superstructures, hollow bows, etc., which are the easiest to achieve and can be achieved after simple experiments.

Some simple techniques were applied, the problem of the center of gravity, the problem of resistance and propulsion in the water, and after these were perfectly solved, it was the current clipper. The first one can maintain a maximum speed of about 21 knots, and the average speed of a non-powered ship can also reach more than 14 knots, which is very scary for ocean-going vessels.

Even if it is the most terrible war weapon built in the power era, a large warship, although it can guarantee a limit speed of 33 knots or even 40 knots, but such a limit speed, how much can it last, in a long voyage, the average speed will not exceed 20 knots.

A completely unpowered vessel can achieve this, and it has to be said that it is very good, and such a classic boat is the most suitable in this era of chart-searching.

However, the formation of a technology, the finalization of a ship, it takes time, not overnight, the same is true of the clipper ship, even if Zhao Xin has drawn the scale in the drawings, and even marked some key parts, it is not easy to realize.

Fortunately, starting from the Spanish sailing ship, the Dinghai Navy has formed a system, a system that is converted from the drawings into the real thing, even if the first, second, and third ships are not so powerful, they can continue to study in the whole direction until the final realization.

The various sub-projects of the clipper ship have been basically completed, and even the sample ship is better than the other, the most recent one, if you really want to say, is already a clipper ship, with a maximum speed of 19 knots, an average of about 11 knots, this speed, perhaps not as good as the complete body of the clipper, but also much stronger than the Spanish sailboat.

Speed is the key to exploration, but this ship is a little worse in terms of stability, and more than a dozen ships built in advance began to carry out experimental navigation in the sea area controlled by the Ding Navy.

The purpose of this voyage is also to improve the chart, all the islands of China, all the latitude and longitude lines from Hainan Island to Vladivostok, all the drawing has been completed, this chart will also become the basis of the future voyage, through this basically determined point, one by one comparison, for the use of the sextant is very critical.

In the middle, there is another convenient condition, Zhao Xin, drew a brief figure, this figure is of course according to the future, the world map, and the Pacific map, maybe the scale or something, not very perfect, the same, the location of some islands is also wrong, but the general above graphics are correct.

From the nautical point of view, it is enough to be generally correct, even if there is some directional knowing, for future nautical expeditions, at least, 90 percent, or even more possibilities are avoided, and there is only one way to success.

At the beginning of China's Age of Discovery, there was only one way, from Japan in the north to the north, an island chain, all the way to the Aleutian Islands, the relative distance between this island chain is not very far.

If the ability to sail at one time is not enough, you can use a relay method to slowly jump over the island chain one by one, and this time will be extended a lot.

However, the Navy is not short of production capacity, and it is not to build some permanent bases, but to build some permanent fortifications, station some personnel, and deliver some supplies on some islands with fresh water, and then it can support long-distance navigation, so as not to gradually lose its way in the long deep-sea voyage.

However, in the early stage, it will be very difficult for the personnel stationed on the island chain to transport all kinds of materials and building materials from a poor and white island, from thousands of miles apart, or even more distances, and successfully build it, initially as a supply port, and then as a base, repair shop, and even a shipyard.

Only the construction of perfect ancillary facilities can make these islands play a greater and more outstanding effect, and will produce great benefits for the whole nautical exploration, but for those who land on the islands in the early stage, in the degree of poverty and nothingness, it will be a nightmare.

Harsh environment, very strict requirements, efficient work, these are difficult to gather together, but have to persevere, their persistence, is good for the whole navigation, but any little problem or deviation, bring, light is a huge accident, the worst, is the price of death.

At present, Zhao Xin's extent, there is no such kind of woman's benevolence, in a country with a population of more than 30 million, in vassals, thousands of miles, the things produced every day, under the premise of countless things, these pioneers can be sacrificed, as long as the effect is achieved.
