The Navy Has No Nuclear Power, So What Does It Have To Do With Our Coast Guard?

“This is the No. 1 ammunition storage of our Coast Guard Ship No. 1601!”

Qin Chuan led several people to the ammunition storage, opened the safety gate and introduced it.

The No. 1 ammunition storage is 40 meters long and about 10 meters wide. It was originally the area where the warship’s transmission shaft was located.

But because Qin Chuan converted the Coast Guard ship into an all-electric propulsion, the 40-meter-long transmission shaft was removed.

So this place was naturally converted into an ammunition storage!

As soon as they entered the door of the ammunition storage, Staff Officer Cheng and others were shocked by its area. With such a large ammunition storage, what the hell does the Coast Guard want to do?

This is a question that keeps appearing in everyone’s heart!

You are enforcing the law!

Not fighting!

Is it necessary to make the ammunition storage so exaggerated?

But then they entered the No. 1 ammunition storage and saw the shells displayed inside. They suddenly understood why the ammunition storage was designed so large.

Because the shells placed here are 4.8 meters long and have a caliber of about 300 mm!

“Is this the shell fired by the electromagnetic railgun outside?”

Captain Liu Hong was a little skeptical of life when he saw such a large shell.

Because the 130mm naval gun only had a 27kg shell, compared to the shell in front of him, it seemed like a toy!

He could hardly imagine that the electromagnetic railgun could fire such a shell 2,000 kilometers away?

“This is a scramjet shell specially designed for the electromagnetic railgun!”

Seeing everyone staring at the shell, Qin Chuan said.

But after Qin Chuan said this, everyone present was obviously more confused.

“I’ve only heard of supersonic ramjets, which are mainly used in hypersonic vehicles!”

“And scramjet shells?”

“If I remember correctly, the prerequisite for the scramjet engine to start is at least Mach 3, right?”

Staff Officer Cheng raised the question again.

“That’s right, if you want a scramjet engine to work, it must be given a speed of Mach 3 or above!”

“But what if we use an electromagnetic railgun to launch a projectile at a speed of Mach 6?”

“When I was developing the electromagnetic railgun, I found it difficult to solve the overload problem of the projectile accelerating beyond Mach 6.”

“Once overloaded, all electronic components used for navigation in the shells will become disabled!”

“So I changed my mindset and designed a large-caliber and heavy-weight shell, using an electromagnetic railgun to accelerate the shell to Mach 6.”

“The rest of the work will be done by the scramjet engine on the shell.……”

Qin Chuan explained.

Through Qin Chuan’s simple and straightforward explanation, Staff Officer Cheng also instantly understood Qin Chuan’s intentions and design principles.

He felt like he had been enlightened, and looked at Qin Chuan in shock.

Because he found that Qin Chuan was really a military design genius!

Although the scramjet engine sounds high-end, it has a simple structure, light weight, and a low price.

It’s just that it requires Mach 3 to start, which is very harsh and difficult to achieve.

But if it is used in the shells of the electromagnetic railgun, coupled with a reasonable design, it may really reach a range of 2,000 kilometers!

“”Chief Engineer Qin, can you explain in more detail the principle of this electromagnetic railgun shell?”

Staff Officer Cheng asked impatiently.

“No problem, Chief!”

“If we want to increase the range of the electromagnetic railgun to 2,000 kilometers, the shells will have to fly outside the atmosphere most of the time, close to a vacuum trajectory!”

“Its peak altitude is about 450 kilometers, and its re-entry speed is about Mach 17!”

“First, we use an electromagnetic railgun to fire the shells, giving them a launch speed of around Mach 6!”

“There are folding wings at the front and back of the shell, which will unfold after launch. The front wing has a Beidou guidance kit to drive the deflection to achieve precise guidance!”

“The projectile head has two conical oblique shock waves, which sweep across the lip of the air inlet. When the Mach 6 incoming flow passes through the shock wave, it is compressed twice and deflected into the air inlet.”

“A small portion of this compressed air will enter the combustion chamber and ignite to form a certain pressure of combustible gas. This combustible gas will come out of the pipeline and mix with the Mach 6 air, and will be detonated like a match in a Category 15 typhoon, forming a shock wave.”

“At this time, the combustion chamber valve increases or decreases the pressure to control the shock wave speed so that it is the same as the Mach number of the inlet airflow. At this time, the flame front is transmitted forward to form a stable deflagration zone!”

“In this way, the scramjet engine can accelerate for a long time after the shell is fired by the electromagnetic railgun, and eventually the speed exceeds Mach 17 before the shell leaves the atmosphere, flying to the apex of the trajectory!”

“……”

Qin Chuan explained the launch principle and process of the electromagnetic railgun.

After listening to Qin Chuan’s story, Staff Officer Cheng was shocked beyond words!

Because this design is absolutely feasible in principle, there is no problem.

In addition, the electromagnetic railgun and the shells are right in front of us, which means that Qin Chuan has really developed an electromagnetic railgun with a range of 2,000 kilometers!

This will be an absolutely shocking weapon!
