After nearly a week of assembly and testing, Roland and Anna completed the development of the bomb touch fuse.
Compared with the fuse of the shell, it does not need to withstand high temperature and pressure, nor does it have high G overload when it is out of the bore, so the structure is extremely simple.
But it was such a thing made of a striker and a spring that the two of them had tested many times before they succeeded.
The main problem is that no one knows how much elastic the spring needs to avoid fire when it falls unexpectedly, and when throwing normally, it is necessary to ensure that the striker can stably trigger the bottom fire.
He and Anna can only test a little bit by changing the thickness and hardness of the spring.
Fortunately, the latter and Lucia did a lot of preliminary work on weekdays, so Roland could use more and more high-quality materials.
The last test was the No. 1365 alloy steel, which has high hardness and low toughness. Even if the bomb lands from a height of one meter, it will not be compressed to the end.
The appropriate spring is selected and the rest is natural.Even if Roland has never seen a real fuse look, he can design one by himself based on its working principle.
Being behind is definitely behind, but for the stupid, big, black and thick bombs, it is useful enough.
The touch fuze of the finished version is like a cylinder, twelve centimeters long and about five centimeters in diameter, with threads below, and can be screwed into the opening at the top of the bomb.
It has a lower convex groove inside, and the striker looks similar, and can be embedded in the groove.
Under normal conditions, its upper part is pushed at the notch by a spring, and the firing needle falls into the groove, just one finger from the bottom fire.
To be on the safe side, Roland also made an extra hole in the head of the firing needle and fixed it to the shell with a bolt. Before dropping the bomb, the firing needle must be pulled out before moving up and down.
The simulation trial was conducted on a sunny afternoon.
Since the bomb was nearly the weight of five nightingales after being filled with sand and gravel and black gunpowder, Roland did not board the hot air balloon, but watched with a look glass at the bomb dropping site 300 meters away.
In addition to him, the first army commander Iron Axe and chief knight Catlanis were also visiting the trial bid.
Are you planning to throw a giant explosive bag into the palace with a hot air balloon?After listening to Roland's combat plan, Carter couldn't believe his ears.
Attacks from a height of two thousand meters and ignoring the city walls and garrison forces completely subverted his previous combat philosophy. Of course, he has been subverted many times in Bianfeng Town this year.
As long as the control is properly, this is not impossible. Roland nodded, Tifeco is forcing a new militia. If he cannot be stopped, the Western Front will inevitably be attacked by the drug-taking army again.Even if you win, it won't bring us a slight benefit.
The secret letter sent by Tassa shows that Tifeko still wants to use the usual old routine to consume his strength, and he doesn't know if the team of messengers sent by Barov can win over more people to the border town before the other party.
If you could really throw the thunderous anger on Tifeko's head, he would definitely be scared and overwhelmed!Iron Axe said excitedly, this is simply an irresistible punishment!
I hope so, Roland smiled.
Although Tasa mentioned in the letter that Tifeko may have figured out the formula of black gunpowder and opened a workshop in the inner city to try to produce such dangerous goods in large quantities, he considered it again and again and again and still selected his target above the palace.
The reason is simple, because the palace is eye-catching enough.
Looking down from a height of 2,000 meters, even the magnificent city of Graycastle is only half a palm-sized size, so you must find a landing point in advance when dropping the bomb.
The palace is in the center of the inner city, with red tiles surrounding it. The top of the palace is paved with pure white stone slabs. It looks particularly eye-catching during the fall, and it is almost impossible to recognize the wrong target.
But the workshop is different.
He did not have a floor plan for the royal capital and no one was guided on the ground, so it was difficult to describe the location of the target clearly with language alone.
In addition, the workshop itself is not large, and once the bomb falls into the residential house, this plan will not be worth the cost.
Suddenly, a white shadow fell straight to the ground, causing a smoke column to rise in the test site, and the dull sound of landing came.
It seems that the bomb has landed. Roland put away his look glass and went to see the results.
After a week of training, Lightning's bomb drop skills have made great progress. The bomb fell less than five meters away from the center of the target. The blasting body was completely trapped in the soil, and the shell was deformed significantly under the impact.
When the Yaowang landed and Anna cut the bomb with a black fire, everyone saw that the soil near the fuse had become charred. This proved that the high-temperature gas from the bottom fire ignited the black gunpowder sprinkled on the surface of the soil, and the fuse itself worked normally.
If the inside of the bullet is filled with nitrified starch, it can easily create a deep pit of four to six meters and kill unobstructed personnel within a range of fifty meters nearby.
Since the bomb development has been completed, the next step is to arrange a combat plan.
Roland glanced at everyone in turn and said slowly, "The plan to attack the capital is scheduled to be implemented next Monday."First of all, the Iron Axe, which leads a team of fifty-man muskets to escort the witch to the outskirts of Silver Light City.There is a mountainous area there that can block the view, which is suitable for setting up camps or releasing balloons.
Obey your order, Your Highness!The iron axe responded.
Don’t we fly directly from the border town?Wendy asked.
No, that was too far. Roland shook his head. It would take at least one week to go from the Western Frontier to the King Capital. It would take about three days to fly directly with the Yaowang. The journey back would take six days.
After the hanging basket was equipped with a throwing rack, he could only carry two people. Nightingale could not go with them. Among the four witches, except Anna, did not have the ability to fight. Spending six nights in the wild was too risky, and he couldn't feel at ease.
If you set out from Silver Light City, you can only take one day to drop the bomb and return before the sun sets.
Next is the Witch, this time the mission staff are Anna, Wendy, Lightning, Maisie, Nightingale and Sylvie.The latter two were responsible for monitoring the surrounding situation of the camp, and the attack process was carried out by the first four people according to the training method, especially the lightning. He looked at the little girl, and it depends on you whether she could succeed.
Leave it to me.The latter patted his chest and said.
Then the last thing I want to say is to be safe, Roland said word by word, I'll wait for you to come back in Bianfeng Town.
Four days later, the first bomb, Dongfeng 1, was loaded by a carriage, and under the escort of the First Army, boarded the cargo ship to Yinguang City.
