Chapter 290 Artillery Range Finding

"What? Surveying the surveying and mapping operation, let's return to Huxin Town?"

The students were stunned, and the news came too suddenly.

Jos helplessly spread his hand to them: "This is the order above, and we just received it."

He secretly complained in his heart, why did he let me convey this unpleasant news.

"Tomorrow or the day after tomorrow we will go to the south to fight with the enemy. Only the necessary defense forces are left here.

The leading student reacted first and whispered, "Mr. Jos ... Maybe we can ..."

Before he finished speaking, Jos shook his head like a wave drum: "I am just a soldier, I can't decide anything. What do you think can go to Bryce or Joyce. "You stay" "

The leader nodded: "Thank you for your reminder, let's discuss it here ..."

Jos said good night, leaving the room, leaving a low -voice discussion student.

"Can't just leave, only a small part of the surveying and mapping work."

"If we go back so smoothly, our group's results must be at the bottom."

"Really unlucky, the lottery was drawn to such a place."

"Tomorrow to discuss with Lord Brass and Lord Joyce."

Nympho

Early the next morning, Bryce and Joyce were discussing things south. They were originally scheduled to start today, but later found that they still need to prepare for many plans.

The guards standing outside came to report, saying that the students of the Vese College asked to see them.

Bryce thought a little, "That group of students? Let them come in."

"What? No!"

When the students came in, they made a request that surprised Bryce -they even wanted to stay here to complete the surveying and mapping operation.

"Huxin Town has repeatedly asked us to ensure your safety. I can't let you run around without guards."

The leading student -the team leader of the group, named Nick, shows anxiety on his face, and asked again: "Lord Bryce, thank you for your safety of our safety, but drawing a map is very important. The work of work is not enough. Alida is developing the mining industry. Exploration of mineral production is inseparable from maps. The map can also provide business people with convenience and promote business development. The map, the formation of troops and formulating the combat plan will be much more convenient.

Bryce only shook his head: "Even if you have 10,000 reasons, I can't run around by you."

The two sides have been deadlocked for a while, but no one has persuaded anyone.

A student suddenly proposed: "Since we can't leave us alone, we will follow you to the south! Anyway, the geographical situation there must be surveyed sooner or later."

"Hey? This idea is good! Please let us follow you!"

Nick supported this idea, and other students nodded.

"Still be troubled! We go to fight? Do you think going to the mountains and water?"

Bryce frowned and continued to oppose. Although he had 100 % confidence in his troops and was attacking, he was changing rapidly on the battlefield, and he could not guarantee that one person and two would not have any bad son.

Seeing that I couldn't persuade Bryce, Nick patted his head and thought of a good idea.

"Lord Bryce, what do you think of this? If you take us, we will teach your artillery to a simple ranging method. You can accurately stand on the artillery position ... uh ... it's relatively accurate Test the distance from the target. "" "."

"oh?"

Bryce and Joyce raised their ears at the same time, and Nick's suggestion poked their pain points.

The Artillers forces of the Alda Army rely on the naked eye estimation of the target distance when they aim, which requires high experience in artillery. Some artillers who are very experienced and the "talents" are extremely high, and you can estimate that you can take a look at the eyes with your eyes. First try a shot, and then slightly adjust the pitch angle or the amount of medicine. gun. However, there are very few talents. Most of the gunners -especially the newly enlisted rookie -have to shift the bounce near the target.

If there is really a method that can be relatively accurate in the cannon position, it can make the artillery play a higher level.

Nick smiled proudly, and the two officers were lifted by his appetite.

Bryce asked: "What are you talking about?"

Nick shook his head: "Then you have to promise us, you can go south with the troops."

Bryce was a little angry. Bastard, Mao did not dare to talk to me. It was an important skill like artillery ranging. I directly buckled your lord's adult.

However, think about a joke of a Chinese school and a group of half -sizes, so I have a joke, so I put down the unhappy emotions.

He looked at Joyce, and the three battalions that were not much bigger than these students were full of [Agreement].

"Oh!" Bryce cleared his throat: "Okay, I agree with you to act with the troops."

"What is the truth of the Lieutenant Colonel?"

There is no mistake, one, one, one, one, one, one, one, one 619, one book, one, one, one, one, one, one, a book!

Bryce puffed his beard and glared: "Will my dignified commander of the First Battalion still lie to you kids? But you, please tell me how to measure distance first!"

"yeah!"

A group of students cheered and their surveying and mapping homework could continue.

Although Joyce is now the battalion commander, as Schroeder's former knight retinue, he was also very young. Seeing the cheers of these students who were a few years younger than him, he was very touched in his heart.

He took a pen and paper and put it on the table. He smiled and said to Nick: "Congratulations, our Commander Bryce is not easy to talk to on weekdays. But don't be too busy celebrating. Tell us first. If I If your guess is correct, it’s probably using the so-called [mathematics], right?”

"Pah!" Nick snapped his fingers, nodded and said, "That's true!"

He picked up the paper and started drawing on it, "This is a method we often use when surveying and mapping..."

Everyone leaned over and saw that Nick had drawn a triangle on the paper, but this triangle was a bit special. Two of its sides intersected perpendicularly. One of the two sides was very long and the other was very short.

As students will recognize, this is called a right triangle.

"Suppose your artillery is deployed here!" Nick drew a circle at the right angle.

Then he controlled the pen tip to move slowly from the right angle along the longer right-angled side (strand) to the smaller acute angle, and finally stopped at the tip of the corner, "This is your bombing target."

"This line segment," Nick thickened the long right-angled edge (strand) that the pen tip passed through, "is the distance between the artillery and the target."

"And this line segment," Nick thickened the short right-angled side (hook line), "is a known fixed distance directly to the side of the gun. To facilitate calculation, it can be an integer, such as one meter or Two meters, you can call it [the baseline].”

"Now, just measure the size of this angle," Nick circled the larger acute angle, "and combine it with the known fixed distance of one meter or two meters..."

"You can measure the straight-line distance between the artillery and the target."

He heavily stroked the long right-angled edge (strand line) several times.

"That's the line!"
