Yuan Fang continued: "Later, Damei carefully investigated, and also asked the dark night to help, and finally found that there may be someone scattered a large number of purchases, although the mastermind behind the scenes was not found, but the dark night found a lot of traces of the Liusang Empire, it is estimated that those fog stones were taken away by the Liusang Empire, with the light stone, the searchlight is not easy to get?" ”

Guan Xiaoyun said with an indignant face: "These brutes are really shameless, first they imitated our airship, and now they are here to steal the light stone, dean, the gunpowder formula must be preserved, and they must not be allowed to go." ”

Yuan Fang sneered and said, "Don't worry, the Liusang Empire is about to be removed." ”

Returning to the studio, sorting out his mood, and devoting himself to research work again, this time the task is to solve the problem of depression angle shooting, for this reason, Yuan Fang also deliberately returned an artillery gun to verify at any time.

Air combat is mainly based on scattered bullets as the main weapon, the composition and launch of the scattered bomb is the thrust generated by the burning of gunpowder, the butt and the upper scattered bullet net out of the gun chamber, when the elevation angle, the scattered bomb bag and the cartridge butt will fit together due to gravity, but if it is changed to a depression angle, the scattered bomb bag or the shell will also be separated because of gravity, and even roll out of the gun chamber, if you want to solve this problem, you must find a way to connect the scattered bullet net and the cartridge butt as a whole, this is very simple, as long as the wire mesh wrapped in the scattered bullet adds a few silk threads to trap the two togetherThe rest of how to keep the whole in its original position without being affected by downward gravity is the key and even more difficult.

First of all, Ye Qingru said his thoughts: "Brother-in-law, why don't we drill a few thin holes in the cannon body, and then use silk threads to fix the butt and shell?" ”

Yuan Fang shook his head and said negatively after a little consideration: "No, drilling holes in the gun body will affect the overall structure of the gun body, greatly reduce the pressure bearing capacity of the gun body, and it is easy to burst." For example, this stick, you can't break it easily, but if you make an opening somewhere, it's different, and the same force will break back at the opening. ”

After being silent for a long time, Xia Yi said his thoughts: "What if you tie a silk thread to the tail end, that is, behind the butt, like a crossbow arrow, and then tie the silk thread through the mouth of the fuse?" ”

This time, without Yuan Fang opening his mouth, Hongyi shook his head and said: "No, the fuse will burn the silk thread when ignition, and it will take some time for the fuse to ignite the gunpowder in the barrel, during this time, the shell will still slide, even if this time is short enough The shell is still in the breech, but this distance will consume a lot of kinetic energy and greatly affect the range of the shell." ”

Time passed little by little, Yuan Fang and the others had no clue, at this time, a tragic battle was going on in the air a hundred miles south of Changhuan Island.

Xueqin took over the command and led a battle formation composed of seventy combat boats from the Naval Air Force and the Provisional Air Force of the Air Force Academy to the South China Sea to meet the enemy, and met in the air hundreds of miles away.

The speed of the small boat of the Dongsheng Empire has a slight advantage, Xueqin took this as the core of the battle, and immediately ordered the formation to disperse, a group of three, a long plane to pilot the selection of targets, two wingmen to escort the left and right, and cooperate with the long plane to fight, this is the main tactic of the Dongsheng Imperial Air Force, and the effect is very good.

Compared with the Dongsheng Empire, which is close to mature flight technology and tactics, these novice pilots of the Liusang Empire seem to be a little more like stragglers, rushing over in a swarm, a face, and being pulled up in the dive Dongsheng Air Force to break the bloodstream, the first round of fighting, the Dongsheng Empire was unscathed, and the Liusang Empire was shot down by almost ten airships, and then, the two sides fell into a struggle, the heavy crossbow of the Liusang Empire and the heavy crossbow of the Dongsheng Empire had the same range, and the power was similar, and the two sides did not distinguish between advantages and disadvantages.

During the struggle, the speed advantage was greatly reduced, and it was difficult to distinguish for a while, and the two sides continued to have airships or boats falling with arrows, and some seriously damaged airships could still insist on flying, or rising or descending to get out of the battlefield, but the fuselage was damaged, the power was greatly affected, and the speed was reduced to the lowest they were live targets, no one could succeed, and all of them were shot down by the other side without exception.

As the last rays of sunlight disappeared and night fell, the two sides turned on the searchlights, but in such a vast sky, the light of the searchlights was as insignificant as fireflies, and instead gave each other a lock mark.

The Dongsheng Empire's dinghy is equipped with five searchlights, two aimed at the front, one at the back and below, and the other two are aimed at illuminating the fuselage to facilitate the identification of your own boat, while the Liusang Empire only installed a searchlight in front and added a not-so-bright marker light at the tail, which is more hidden in comparison.

Seeing that the opponent's boat was like a beacon, the commander of the Liusang Empire didn't know what to think, so he ordered his own side to turn off the searchlight, and as a result, the boat of the Dongsheng Empire suddenly lost its target, and spun around in this airspace like a headless fly, becoming a target for the enemy hidden in the dark, and was shot down ten planes in successive waves of attacks.

The form took a sharp turn, Xueqin became unfazed, and calmly gave the order to shrink the battle space, with Ding Bu as the shoulder, forming a goose-shaped formation, circling and turning to the north.

At this time, the speed advantage of the Dongsheng Empire's small boat played a huge role, and the opponent could still attack and intercept at the beginning, and then the distance between the two sides became farther and farther, and after getting out of range, the airship of the Liusang Empire could only grit its teeth and chase closely.

Xueqin took over the position of the arrow, and took all the dinghy to do irregular circling forward, and the Liusang airship that followed behind of course wanted to catch up at the closest distance in a straight line, but as a result, it was pulled by such a pull, and the originally scattered airship was unconsciously pulled into one place, as a result, there was no lighting positioning, and there were continuous collisions, and the speed at that time was not slow, and most of the airships that collided with the Liusang Empire were seriously damaged and had to withdraw from the battlefield or crash directly.

After a long turn, the erh reconnaissance boat under the formation continued to report the number of enemy aircraft crashed with the help of the moonlight in the sky from an upward perspective, until this time, everyone had a new understanding of the delicate and moving Xueqin, calm and calm, not alarmed, with a sharp and flexible mind, clear and clear thinking, definitely not a vase that relies on beauty to have today's status, this point, the cadets of the Air Force Academy have long understood, and the pilots of the naval air combat unit do not know until today.

The airships of the Liusang Empire collided frequently, and the commander hurriedly ordered to turn on the searchlight, but it was too late, after counting, there were less than twenty airships left on the Liusang Empire's side that could still fight, and the other party, there were nearly fifty airships, the number was so disparity, the commander of the Liusang Empire had to give up this operation and ordered a retreat.
