In the evening, Prince Heinrich returned to the hotel where he was staying and carefully watched the drawings given to him by Qin Zheng. Prince Heinrich served in the German Navy, so he is not unfamiliar with warships. First look at the parameters of the warship: the length of the ship is 128 meters, width: 16 meters, draft: 6 meters, standard displacement is 6,000-6,500 tons, power output is 18,000-20,000 horsepower, estimated speed is 25-26 knots, ship-based weapons are 6 double-mounted 155 mm caliber 45 times the distance naval gun, 8 double-mounted 100 mm caliber 45 times the distance naval gun, 12 double-mounted 50 mm caliber machine guns, two-mounted 3-mounted launchers, and crew members are 400-500.

Judging from the performance data, it generally meets the standards of a large protective cruiser of 6,000 tons, and the ship-based weapons are divided into three levels, which are very obvious. This not only ensures the firepower of the entire ship, but also simplifies the composition of weapons and reduces the difficulty of logistics and replenishment. However, the expected speed is 25-26 knots, which scares Prince Heinrich. In this era, several types of protective cruisers with fast speeds, Prince Heinrich knows that Japan's Yoshino is 23 knots; the Qing court's Haitian and Haizhe are 24 knots; Russia purchased the Varyag from the United States with 24 knots. Germany also built several large protective cruisers, one is Queen Oxta-class protective cruiser with a speed of 21 knots; the other is Queen Louise-class protective cruiser with a speed of 20 knots, which is not considered a fast protective cruiser.

Prince Heinrich certainly knew that ship speed, firepower and defense are the three major elements of warships, and these three elements are mutually restricted. They can only be different based on the uses of various warships. The main function of protecting cruisers is fleet escort, breaking, and counter-breaking, etc., rather than being used for decisive battles at sea, so they pay more attention to speed rather than firepower and defense. The two types of German Queen-class protective cruisers are not fast, which means that they pay too much attention to protection, which affects the speed.

If the speed of this type of protective cruiser designed by overseas Chinese can really reach more than 25 knots, it will be the fastest warship at present, and it will have a great advantage in maritime battles. Compared with the German Queen Oksta-class protective cruiser, if the two ships have their own strengths, they can only be said to have their own strengths, and the winner is 55, but if the battles are carried out, then the Queen Oksta-class protective cruiser will definitely be worse than that.

Moreover, Prince Heinrich did not suspect that overseas Chinese were deliberately exaggerating their performance, because last time he saw several warships of overseas Chinese could travel at high speeds of more than 25 knots.

Then Prince Heinrich went to look through the drawings again. Because it was a primary design, the drawings were very simple, with only one floor plan, one elevation plan, and two sectional plans. However, when you look at the drawings, Prince Heinrich could see that it was very different from the warship design of this era, with a very typical warship style of overseas Chinese.

First of all, from the overall structure of the warship, it adopts a long forecastle structure. The bow of the ship adopts a large oblique flying scissor-shaped bow, which is as sharp as a front, and the cross-section of the hull shows a clear "v" shape of floating structure, while the planar structure adopts a pointed end round tail shape. These structural designs are very obvious from the warships of this era. The bow of the warships of this era is generally vertical or inclined drilling wave shape, while the cross-section of the hull is either a "u" shape or an inclined shape, while the planar arrangement is a spindle-shaped design with both tips.

However, these designs can be found in the warships of overseas Chinese, which also shows that such designs as overseas Chinese are not deliberately innovative, but rather the ship-style design style that overseas Chinese are used to.

But what Prince Heinrich didn't understand is that there is a hemispherical structure protruding forward below the waterline of the ship, which is somewhat like the impact angle of a warship. However, if it is a collision angle, it should be pointed-shaped rather than hemispherical. Moreover, the length of the impact angle should be protruding from the bow of the ship, so that it can impact the enemy ship. However, this warship adopts a large oblique flying scissor-shaped bow. Therefore, although the structure under the waterline protruding forward, it does not protrude beyond the bow of the ship, so of course it will not be a collision angle.

In fact, the warship hull designed by the time traveler is the hull appearance that has been proven to be optimized by the fluid dynamics theory and practice in the old time and space. The large angle flying scissor head and the "V"-shaped outer floating structure hull can all increase the stability and seaworthiness of the hull and resist storm; the plane shape of the pointed and round tail is more conducive to reducing the water flow resistance during high-speed navigation.

The protruding hemispherical structure under the waterline of the ship is called a bulbous bow or a bulbous bow. Its main function is to make the peaks and troughs of the waves formed by the hull and the bulbs meet each other and offset each other, and to improve the line shape of the ship's head, the curvature of the hull part of the waterline is to reduce the vortex resistance and increase the speed. According to the experience of old time and space, ships using a bulbous bow can reduce the seawater resistance of about 10-15%. It is precisely because of so many designs of de-resistance, increase speed and stabilizer that the crosser dares to set the navigation to 25-26 knots. Moreover, according to computer simulation calculations, the theoretical maximum speed can reach 26.7 knots.

The arrangement of ship-based weapons is a standard. Six dual-mounted 155mm caliber main guns are placed at the tail of the ship, respectively, in an inverted "quality" shape of two fronts and one back. However, the position of the latter main gun is higher than the first two main guns, so the barrel of the rear main gun is above the first two main guns, which can save deck space. This kind of artillery arrangement method was called a back-loaded structure in the old time and space, and it was also the most mature artillery arrangement method in the era of heavy ships and giant guns. The 8 dual-mounted 100mm caliber secondary guns and 12 dual-mounted 50mm caliber machine guns are all arranged on both sides of the decks.

When Prince Heinrich saw this, he couldn't help but praise the ingenious conception of overseas Chinese. The Brandenburg-class battleship built by Germany designed to arrange three double-mounted artillery along the central axis of the hull. However, due to the limited space on the deck, the main guns on the first and second diameters of the ship were all 40 times the distance, while the two main guns in the middle could only use 35 times the distance. Although 6 main guns were forced to be blocked, they could not use unified shooting parameters. Instead, they had to install two sets of sighting equipment. Therefore, the battleships built by Germany later were changed to only install two main guns on the first and second diameters of the ship. However, if the Brandenburg-class battleship adopts a back-type structure, the problem can be perfectly solved.

Although in this way, only 8 main guns can be concentrated on the sidewalk fire. On the contrary, 6 main guns can be concentrated on the front and back, and the firepower is extremely powerful. However, the protective cruiser is not used for maritime operations. Therefore, there is no need to deliberately pursue the maximization of the sidewalk firepower. On the contrary, in the execution of a broken battle, the front and back firepower is more important. This also shows that overseas Chinese have a clear and clear idea of ​​designing this type of warship, which avoids the desire to cover everything, but ultimately mediocre.

The sectional diagram also specifically stated that the thickness of the dome armor is 80-120 mm, and a 2.1-meter-high side armor defense belt was installed near the waterline, with a total length of about 50 meters and a thickness of 80-100 mm. Although from a standard point of view, protective cruisers do not have side armor, a small number of thin armor defense belts are sometimes designed on large protective cruisers to strengthen defense.

After reading the drawings, Prince Heinrich also had a general understanding of the warships to be built by overseas Chinese. Although there are many structures that cannot be understood, Prince Heinrich is still very optimistic about the warship design capabilities of overseas Chinese. After all, overseas Chinese have the record. If the warship design capabilities and German shipbuilding capabilities can be combined, it would be of course better. If Germany can win this contract, it will be a great opportunity to test the warship design capabilities of overseas Chinese. If the results prove the warship design capabilities of overseas Chinese, then it should really deepen cooperation with overseas Chinese.

Of course, Prince Heinrich had no objection to participating in the bidding. This is a very common behavior in European commercial activities and reflects the principle of fair and notarized competition. However, absolute fairness does not exist, even if it is a bid. Most biddings have certain understatement operations. Prince Heinrich is very clear about this, because he is a member of the German royal family and has a large number of projects that require bidding every year, and of course he has seen a large number of understatement operations.

Judging from the current situation, at least Qin Zheng is inclined to Germany, and giving the drawings to Prince Heinrich is a very obvious behavior. Although other manufacturers will definitely get the drawings after registering, Germany is one step ahead after all. Of course, Prince Heinrich is not a child, and Qin Zheng's behavior is too bold and obvious. Therefore, it is not ruled out that overseas Chinese have already tended to Germany, and holding this bid is just a way to reduce prices, which is also very common in Europe.

The specific bidding quotation is the manufacturer's business, and it has nothing to do with Prince Heinrich. His responsibility is to pass the news back to the country and provide some relevant reference materials to the country. Therefore, Prince Heinrich put down the drawings, took out paper and pen, and carefully drafted a large telegram manuscript, wrote down the detailed situation and his own ideas, and then sent them back to the country overnight.

On the next day, the Navy Command officially submitted the shipbuilding plan for 1902-1903 to the Senate Parliament. After discussions by the House of Commons, the Navy Command finally passed the proposal. The shipbuilding funds for 1902 were withdrawn from the reserve fund, and the follow-up funds for 1903 were made in the financial plan of that year.

Although the cost of building a ship is huge, more than 40% of the veteran members are soldiers, and they are from the navy. Naturally, they will fully support the navy's shipbuilding plan. In addition, the construction of warships is also to protect the security of the East China government. To a certain extent, it can also promote the industrial development of the East China government. Moreover, with the current financial resources of the East China government, it is still affordable, so the adoption of the proposal is not surprising.
