Release that Witch Chapter 303: Air Strike Preparation

After nearly a week of assembly and testing, Roland and Anna have completed the development of the bomb touch fuze.

Compared to the fuze of the projectile, it does not need to withstand high temperatures and pressures, and it does not have a high g overload when discharged, so the structure is extremely simple. But it was such a thing consisting of a firing pin and a spring that the two also tested many times before it was successful.

The main problem is that no one knows how much spring force is required to prevent the fire from falling when accidentally dropped, and the normal firing must ensure that the striker can 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 have done a lot of preliminary work on weekdays, so Roland has more and more high-quality materials available at hand. The last test passed was 1365 alloy steel, which has high hardness and low toughness. Even if the bomb falls from a height of one meter, it will not be compressed to the end.

A suitable spring is selected, and the rest is in place. Even if Roland has never seen a real fuze, it can design one by itself based on its working principle.

Behind is definitely behind, but it's enough for a silly and thick missile.

The completed touch fuze is like a cylinder, twelve centimeters long and about five centimeters in diameter, with a thread below it that can be screwed into the opening at the top of the bomb.

Its interior is a downward convex groove, and the striker has a similar appearance, and can fit into the groove exactly. Under normal conditions, its upper part is pushed against the notch by a spring, and the striker falls into the groove, just a finger away from the bottom fire. For the sake of insurance, Roland also made a hole in the head of the striker pin, and fixed it to the ammunition case with a bolt. Before the bomb is dropped, this iron rod must be pulled out before the striker can move up and down.

Simulation trials were conducted in a windy and sunny afternoon.

Since the bomb has been filled with gravel and black gunpowder, the weight of the bomb is close to five Nightingale, so Roland did not board the hot air balloon, but watched with telescope three hundred meters away from the bombing site.

Apart from him, there were First Army command Iron Axe and Chief Knight Carter Lannis in the trial investment.

"Are you going to throw a giant dynamite into the palace with a hot air balloon?" After listening to the Roland battle plan, Carter couldn't believe his ears. Launching an attack from a height of two kilometers, ignoring the city walls and defensive forces, completely overturned his previous operational philosophy. Of course, in the year of Border Town, he has been subverted many times.

"As long as it is properly controlled, this is not an impossible implementation," Roland nodded. "Timothy is forcing a new militia team. If it cannot stop him, Western Region will inevitably be attacked by the Shaoyao Army. Even if it wins, It will not bring us the slightest benefit. "

The secret letter sent by Tasa indicates that Timothy still wants to use the same old routine to consume its strength. It is also unknown whether the envoy team sent by Barov can draw more people to Border Town before the other party.

"If you can really cast Sky Thunder's Wrath on Timothy's head, he will be frightened and overwhelmed!" Iron Axe said excitedly, "This is the heavenly punishment that is irresistible!"

"I hope so," Roland smiled.

Although Tasa mentioned in the letter, Timothy is likely to have figured out the formula of black gunpowder and opened a workshop in the inner city to try to mass produce such dangerous goods. However, after considering it, he still chose the target. Above the palace.

The reason is simple, because the palace is striking enough.

From a height of two kilometers, even the most magnificent city in Greycastle is only half a slap in size, so you must find a landing point in advance when you drop a bomb. The royal palace is located in the center of the inner city, surrounded by red tile walls. The top of the palace is paved with pure white stone slab. It looks particularly eye-catching during the fall, and almost impossible mistakenly identified the target.

But the workshop is different.

He doesn't have the floor plan of Kingdom Capital on his hands, and the ground is not guided by anyone. It is difficult to describe the location of the target by words alone. Coupled with the small size of the workshop itself, once the bomb fell into the dwellings, the plan was worth more.

Suddenly, a white shadow plummeted to the ground, causing a plume of smoke to rise in the test field, and then a dull sound of floor sounding came.

"It seems the bomb has landed," Roland put away telescope, "Go and see the results."

After a week of training, the Lightning's bombardment skills have made great progress. The missile landed less than five meters away from the center of the target. The body of the bomb fell into the soil, and the shell was greatly deformed under the impact.

When the Vision 21 landed and Anna cut the bomb with black fire, everyone saw that the soil near the fuze had become black. This proved that the high-temperature gas of the bottom fire ignited the black gunpowder scattered on the soil surface. The fuze itself works fine. If the inside of the bomb is filled with nitro starch, it can easily produce a chasm of four to six meters and kill unobstructed personnel within 50 meters of nearby.

Now that the bombs have been developed, the next step is to arrange a battle plan.

Roland glanced at everyone in turn and slowly said, "The surprise Kingdom Capital plan is scheduled to be executed next Monday. The first is Iron Axe. You will lead a fifty-person firearms team to **** witch to the outskirts of Silver Light City. There is a piece there The mountain ridge zone can block the field of vision, whether it is setting up a camp or flying balloons. "

"As you bid, Your Highness!" Iron Axe responded.

"Are we not flying directly from Border Town?" Wendy asked.

"No, that's too far away," Roland shook his head. It took at least a week to travel from Western Region to Kingdom Capital, and it took about three days to switch to the direct flight, and it took six days to count the return journey. After installing a throwing rack in the gondola, he can only carry two people. Nightingale cannot go with them. None of the four witch except Anna has the ability to fight. It is too risky to spend six nights in the wild, and he cannot rest assured. "From Silver Light City set off, you can complete the bombing in one day and return to the sea before the sun sets."

"Next is witch. This time, the mission personnel are Anna, Wendy, Lightning, Macy, Nightingale and Silvie. The last two are responsible for monitoring the situation surrounding the camp. The attack process was implemented by the first four according to training methods, especially Lightning, "he looked at the little girl," it depends on you if you can succeed. "

"Leave it to me." The latter patted his chest.

"The last thing I want to say is, pay attention to safety," Roland said, "I'll wait for you back at Border Town."

Four days later, the first bomb, Dongfeng-1, was loaded by a horse-drawn carriage, and escorted by the First Army team, boarded a cargo ship bound for Silver Light City. (To be continued., Your support is my greatest motivation.)
