Chapter 286: Cannon Test

    But now, 4,000 rounds per minute is an order of magnitude higher. If it hits the target, it will directly smash the target into a sieve.

    "My dear, how much ammunition is wasted?" Li Yunlong couldn't help but said.  Before the development of the Eighth Route Army's military industry, the Eighth Route Army's ammunition was extremely scarce.  A fighter often only has three bullets, so it is called three guns and eight roads.  Now as Qin Baoshan continues to promote the development of the Eighth Route Army's military industry, there is no shortage of bullets. Troops like Li Yunlong can also be equipped with some automatic weapons to increase the firepower density, but even so, they will never imagine a cannon  It can be fired so quickly, which is definitely a waste of shells.

    Qin Baoshan smiled: "Old Li, we can't afford this thing. It's too wasteful to use it on the ground. If it's used in the air, it will be enjoyable."

    When the planes in the air carry out machine gun strikes on the ground, the effect is not good, because the speed of the plane is very fast, and the bullets cannot be fired much during the flight, so if there is such a weapon as now, then it can be used  A large number of bullets were fired.

    Of course Li Yunlong knew what Qin Baoshan meant.  Although he was a little reconciled in his heart, if his troops were to be equipped with this kind of weapon, he would really be reluctant to waste shells.  Only Americans can use it.

    "If the caliber of this gun is larger, will it be more powerful?" Li Yunlong raised his second question.

    Qin Baoshan nodded: "Of course there is no problem, but if the caliber is larger, the weight of this gun will increase, making it inconvenient to carry. Therefore, the caliber of 20mm should be more suitable for airborne. If the caliber is larger  If not, then it can only be equipped on warships.¡±

    When watching a movie, you can often see the protagonist raise this kind of cannon with a revolving tube and shoot at the enemy. The scene is very bloody and very eye-catching, but it is actually all nonsense.  A revolving cannon is definitely not something that one person can lift, even one like Rambo is no exception.

    "Qin, are we going to start test firing now?" Cochran stood aside and couldn't bear it anymore.

    Qin Baoshan nodded: "That's right, we can start the test shooting. You all stay away. This weapon has just been manufactured, and there may be problems. If it explodes or something flies out,  It will hurt you."

    As Qin Baoshan said, he planned to operate the revolving cannon, but before he touched it, Li Yunlong took the lead.  Li Yunlong stood directly behind the revolving cannon, holding the operating handle on the tail of the cannon with both hands, and said to Qin Baoshan, "Are you going to fire? Let Lao Li do this kind of work. We haven't found the trigger yet."  , how should it be activated? Is it by pressing the button here?"

    There was a black line on Qin Baoshan's face. This was the first Gatling cannon on board.  Before I had a taste of it, Li Yunlong took the lead.  But now he couldn't say anything to protest, because he was too slow to start.  At this time, Li Yunlong had found the operating mechanism and pressed the button on it.

    If you want to activate the cannon, you have to let it rotate.  Qin Baoshan adopts the simplest electric drive method.  This button is the firing switch of the cannon. As Li Yunlong pressed the button, Weng humming sounded. Stimulated by the current, the motor started to rotate, driving the entire gun barrel to rotate.

    At this moment, Li Yunlong felt that his hands were starting to go numb, the vibration was so strong.  The barrel starts to rotate, and when each barrel turns to the top, it will shoot the shell forward.  Then the gun barrel continues to rotate to complete the ejection action.  The second gun barrel rotated up and continued to shoot, so that the six gun barrels kept rotating and the shooting continued.

    In fact, there are two ways of this machine gun, one is to rotate the barrel, and the other is to rotate the barrel.  If the barrel is rotated, the structure of this gun will be greatly simplified.  With only one gun barrel, the launching work of all sub-cannonballs can be completed.  But in fact, there is no such mechanism used in any rapid-fire gun.  Although it is said that the number of barrels is saved, only one barrel is used, and the barrel wears out quite quickly.  Thousands of shells per minute are fired, and it may only be fired for one minute before the barrel is scrapped. Therefore, in order to increase the life of this gun, it is necessary to use the method of rotating the barrel.  Although the rate of fire is very fast in this way, the workload is not too much when it is assigned to each barrel.  When the barrel is rotating, it is also easy to cool down, which is the most suitable layout scheme for machine guns.

    At this time, the barrel was rotating and the muzzle was firing.  The shells flew forward. Generally speaking, when firing a gun of this caliber, there should be a booming sound.  But because the rate of fire is too fast, all the sound sets?Together.  That changes.  People who are a little farther away feel more obvious. First, there is a buzzing sound, which is the sound of an external motor driving the barrel to rotate.  Then there was a bang, and all the firing sounds came together to form such a special sound, as if a large-caliber cannon was firing.  It is also like the sound of a large number of artillery firing and overlapping.

    Li Yunlong only felt his hands shaking with the cannon, and before he knew it, his fingers loosened from the button.  The gun also stopped firing at this time, the barrel turned slowly, and then stopped.  The whole process only lasted a few seconds, and Li Yunlong already felt that his hands, arms, and even his whole body were numb.

    The shells were flying forward, and at the target 500 meters ahead, a steel plate serving as the target was undergoing a severe test at this time, and the rumbling sounds merged together to form an even louder rumbling sound.  It's like a symphony.  After the roar passed, the target had been smashed to pieces.

    "His grandma's, it's really fun." Li Yunlong said, and wanted to press his finger up again. Seeing this situation, Qin Baoshan pushed him away: "Old Li, it's just fun. You still want to operate,  Take a look below."

    Li Yunlong looked down, only to find that the ammunition box below was empty.  Since only the gun body has been successfully developed, the most common way of feeding ammunition with a belt is still used.  Below is a large box with 100 rounds of shells inside.  But with Li Yunlong's bombardment just now, all the ammunition of the 100 rounds of shells has been shot out.  Isn't this too fast?  (Remember the site URL: www.hlnovel.com
