Roland watched Lyubov's back disappear at the end of the stairs of Geert's Palace, turned around and stopped a cab on the side of the road, gave the coachman five gold coins, and chartered the carriage to serve him all night. Pen, fun, pavilion www. biquge。 info

The Dawn landed at the airship factory for maintenance, and will fly to the sea early tomorrow morning to join the fleet and participate in the battle to capture the Monster Island.

Roland, accompanied by the Edric siblings, visits the arsenal next door to the dockyard and confirms that the new aerial bomb is progressing well. The traditional bomb, which was originally filled with alchemical powder in wooden barrels, is now shelled with pig iron and copper, and the shape is also modeled after Roland's suggestion, modeled after the aerial bombs on Earth, changed to the shape of an olive-shaped with a pointed head and a big belly, and is equipped with a tail fin.

According to the actual needs reflected in the war, Roland put forward the modification requirements for the fuses of aerial bombs. In the past, the blasting barrel thrown by the giant eagle used the thunderstorm stone as the fuse, and immediately expanded and exploded after being impacted, and the shock wave and high temperature and high pressure caused by the explosion ignited the alchemy gunpowder, causing a more intense detonation, and the whole detonation process took a very short time, and the blasting barrel would explode the moment it hit the target.

Such an instantaneous fuse is very effective for striking open-air targets, such as the personnel and superstructure on the deck of the battleship, but the barrel itself lacks penetrating power, coupled with the instantaneous explosion of the fuse, it is difficult to break through the armor protection to kill the hull and the internal facilities of the building, which leads to a general embarrassing situation on the battlefield: after the giant eagle takes turns to bomb, the superstructure of the enemy ship is almost whitewashed, and the fire on the deck seems to be miserable, but the loss of personnel hiding under the main deck is not large, and the ship's guns and engines are also protected by armor. You can still continue to sail or fire back with guns, and a lot of bombs are wasted, but the effect is not as good as it should be.

The same problem is the case when bombing enemy shore forts, especially the stone-stacked, well-defended shore forts, which are unlikely to be destroyed no matter how many bombs you drop.

In order to enhance the damage to the armor and the internal facilities of the building, Roland proposed an idea based on the experience of the development of military science and technology on the earth: to design a delayed detonation fuse, combined with a more penetrating pointed metal shell bomb, after smashing through the armor and buildings, the explosion will occur inside the facility.

He himself lacked sufficient knowledge of science and engineering, nor did he understand any military technology, so he could only draw such a general idea based on the impressions of reading the biography of war history, and put forward such a general idea.

Sukhoi and Morozov did not disappoint him, and soon came up with a design scheme for a "time-delay fuse".

The initiating charge used in the fuse is still thunderstone powder, but the initiating charge is no longer in contact with the alchemical powder, but is loaded into a slender metal tube, the head is connected to the warhead firing pin, and the tail is inserted into the alchemical powder and blocked with a wooden bolt.

When the bomb is thrown, the center of gravity is forward under the influence of the tail and structure, and it automatically keeps falling vertically, the warhead striker hits the target, and the impact force excites the initiating charge, and the initiating charge burns along the copper tube, constantly producing gas, constantly expanding, and the pressure reaches a certain level, it will break open the tail cork, and the high-temperature gas ignites the alchemy gunpowder, and then explodes.

By adjusting the length of the copper tube, the amount of initiating charge, and the number of threads in the stopper, it is possible to change the time of detonation of the bomb, thus creating a time-delay fuse that meets various needs. After the bomb test, you can find an optimal detonation time to ensure that the bomb will detonate as soon as it penetrates the armor - getting up too early will not have the effect of armor piercing, and too late may lead to detonation after penetrating the target, which is no different from throwing a solid iron ball, wasting an expensive bomb in vain.

Different armor and building materials take different times to penetrate the same time, and testing and summarizing a data table requires a lot of repeated experiments, which is the most time-consuming stage of developing a new aerial bomb.

Roland himself didn't know much about experimental science, and he couldn't help much with specific affairs, so he had to engage in spiritual mobilization, encouraged the R&D personnel, and promised to fight for a bonus from Lyubov for them after the project was completed, which won a lot of cheers, and the personnel involved in the project seemed to be full of enthusiasm.

Roland has great respect for these technicians who are on the front line of research and development, and even considered paying bonuses for them out of his own pocket. However, the problem is not money, he can give bonuses to the employees of the airship company, but it is not suitable to do this to the employees of the arsenal, otherwise he will be suspected of overstepping, after all, he is only the majority shareholder of the airship company, but he has never held the shares of the Yangbo family arsenal, and it is not good to say that the name is not right.

The new bombs are divided into four different sizes: 100 pounds, 300 pounds, 500 pounds and 800 pounds.

The 100-pound and 300-pound bombs are designed for the Giant Eagle, and the 500-pound bomb Giant Eagle can also carry one, while the 800-pound heavy bomb is very difficult for the Giant Eagle, and the barely mounted will obviously hinder flexibility, and the weight will consume too much physical strength, and the sailing distance will be shortened accordingly.

Therefore, except for elite soldiers like Aurora who have an extraordinary professional level and are full of energy, Roland does not recommend ordinary Giant Eagles to carry 800-pound aerial bombs.

Since it is not designed for carrier-based aviation, what is the use of these bombshells that were produced overnight?

Of course, it was still used to bomb pirates, but it was not the giant eagle that was responsible for dropping the bomb, but the aerial bomb launch tube installed on the airship was directly ejected to bomb the enemy's important military facilities.

In order to strengthen the air armament, the small airship "Dawn" was also urgently repaired, equipped with a launch device and 60 bombshells, and set sail with the eldest sister "Dawn" early tomorrow morning, and directly took a straight line to take a shortcut over the coastline to the Giant Demon Island, and was scheduled to meet with the White Ou Harbor Fleet at noon, and the air and sea jointly launched a general attack.

After visiting the arsenal, Roland took a horse-drawn carriage to the trading grounds.

At this time, it was almost dusk, and when Roland got out of the car, he saw a dark red patch in front of the steps, and blood stains were like. Glancing up at the rooftop, I couldn't help but sigh.

When passing by a local financial building, he saw a police car blocking the square, dragging away a black body bag, and a dazzling blood mark remained on the tiled floor, which was washed away by the fire faucet. The scene was so similar to what I saw in front of me, reality and memories were reunited in my mind, and my heart was inexplicably blocked.

The trading hall on the second floor, which had been noisy all day, was empty at the moment, and Katya learned that he had arrived at the door and took Antron and Orome downstairs to greet him. They all looked tired, but their spirits were unusually high.

Roland knew that they had just won a difficult victory on that battlefield without gunpowder, and that he had earned him a lot of bloody chips by stepping on the bones of countless speculative losers, so he hid his heart and stepped forward to shake hands and hug the three heroes, congratulating them on a great victory.
