Chapter 1352 Mobile Trajectory
After admiring it with bated breath for a long while, Liang Yan just recovered from the shock of seeing the hypersonic aircraft for the first time.

As a commander of the Second Artillery Corps, he was naturally aware of the "partially successful" test flight of the X51A at the beginning of the year, as well as the recently hyped HTV2 "Falcon".

Even in the office of the brigade commander of the 810th Brigade, there are a lot of foreign reports and technical information collected through various channels.

It is to ensure that we know ourselves and our enemies.

After working so hard, I found out that there was a problem with "knowing myself".

Although Liang Yangang does not understand any particularly advanced technology, from any angle, the "Xuanniao" verification platform in front of him is very similar to the HTV2 design previously announced by Lockheed Martin.

Or strictly speaking, it should be the other way around this time.

HTV2 is very similar to Xuanniao.

After all, the former is still at the conceptual PPT stage, or at most the design drawing stage.

The full-size model of the latter is already on display here, and judging from the operations of superiors, even the test launch mission has begun preparations.

Therefore, the first sentence that came to his mind was——

I didn’t expect that the development of our country’s weapons has already developed to this point?

But when there was another designer standing right next to you, it seemed a bit ignorant to say such things.

Although Liang Yangang has now admitted in his heart that he really has no knowledge, he still cannot show his weakness on the surface.

So he swallowed the words that were on the tip of his tongue and asked another more specific question:
"So... the power section of the DF-16 is designed to be very short, just to leave enough space for the warhead in front... well, this hypersonic verification platform?"

The entire hypersonic project was kept top secret until it was officially equipped to the troops, and even within the Second Artillery Corps, only a very small number of people knew the full situation.

However, since Liang Yangang has already arrived at the Dingxin Base, there is nothing to hide about these situations.

"Yes."

Xing Muchun nodded:
"In addition to the consideration of volume, a gliding hypersonic missile needs to reach a very high initial velocity in a relatively short working time, so the requirements are somewhat different from those of conventional ballistic missiles... Of course, the more specific content involves ballistic planning and calculation. If you want to listen, I can..."

Liang Yangang had just graduated from the military academy and was somewhat confident in his math skills. Upon hearing this, he quickly interrupted the other party with a new question:

"Then the Dongfeng 16 medium- and short-range missile can have such a large volume, is it also because of the ballistic design problem?"

This is what he has been thinking about since he first received the test bomb a few months ago.

"We are mainly responsible for the waverider vehicle part. The missile itself is developed by our sister unit, so I can't be particularly sure."

Xing Muchun first came up with a disclaimer:

"But logically speaking, if a slightly smaller warhead is chosen, the missile can be stuffed into the Taian TAS15 chassis, which is the same as the Dongfeng 5450. As for the appearance you see now... it is because the design team went against all odds and made a warhead with 4.5 tons of explosives..."

Liang Yangang had been operating simulated bullets before, which only had the same size and center of gravity distribution as real bullets, but did not have a more detailed internal structure. Now when he heard this number, he couldn't help but gasp.

"hiss--"

He subconsciously touched the back of his head:

"4.5 tons... If this thing is put into service, will it be the largest non-nuclear warhead our army has ever equipped?"

Xing Muchun came from the aerospace industry, so he was not very sure about these questions involving the history of the development of weapons and equipment, and seemed a little hesitant.

"If we just talk about the equivalent, then it is definitely the case."

At this time, another technician nearby answered very confidently:
“3000-2型自由落体航弹的总重只有2.8吨，装药更是才1.5吨左右，东风16的标准弹头一枚顶它三个……”

Xing Muchun looked over with some surprise:

"How do you know so well?"

"I have quite a few acquaintances at the Second Academy... It is said that when the chief designer of the model finally decided on the design plan, although on the surface he said that he wanted to make the total length of the missile as consistent as possible in order to achieve subsystem commonality with us, in fact, it was purely to satisfy his desire to build a big bomb..."

Hearing this answer, the corners of Xing Muchun's mouth twitched a few times. Liang Yangang understood this mentality a little.

Due to the limitations of the army and navy in terms of firepower projection, the Second Artillery Force's main competitor within the military has always been the Air Force.

Originally, the Second Artillery was ahead by several positions without a doubt, thanks to its advantages of being difficult to intercept and able to strike acupoints from a distance.

But in recent years, with the gradual deployment of various advanced fighter jets and new types of ammunition, the situation seems to be reversed.

After all, the Air Force still has an insurmountable advantage in terms of ammunition delivery density.

So when Liang Yangang heard "one Dongfeng 16 can withstand three 3000-2 bombs", he also felt secretly happy...

……

After all, Liang Yangang was not a R&D personnel, so the discussion about the missile itself ended quickly and the topic returned to the subsequent test work.

"So... during the entire testing process, what are the areas that we need to pay special attention to?"

He asked cautiously.

The training level of the 810th Brigade is undoubtedly excellent, but as the unit with the least experience in equipment replacement in the entire army, it does not have much experience in participating in finalization tests.

Xing Muchun did not answer immediately, but took Liang Yangang into an inconspicuous small door nearby.

It was only then that the latter discovered that this place that looked like a warehouse actually contained a meeting room with complete facilities.

As if seeing his confusion, Xing Muchun introduced:
"In the early days of preparation for war, the Air Force planned to build a base here with the main part running underground, leaving only a part of the runway above, to take off the Q-5A and drop hydrogen bombs on the enemies heading south... Of course, the Hurricane I later completed a nuclear trigger, and the Q-5A was abandoned halfway through, so the base was abandoned halfway through construction until it was recently used by us."

Liang Yangang doesn't know much about the Air Force, but he knows that the J-5 is a small plane with a short range:
"Isn't the base a bit too far back for this function?"

The superiors' idea for the invasion from the north was to attack from the northeast and northwest wings, but the location of Dingxin was quite a distance away from either side.

"That's not clear... maybe our predecessors didn't even consider the return fuel issue."

As he spoke, Xing Muchun had already turned on a large LCD monitor at the end of the small room.

Compared with the combination of a projector and a screen, the new device's display is much clearer.

The above is the relationship curve between ballistic parameters and a series of indicators such as fuel consumption, lift-to-drag ratio, load, dynamic pressure, rudder angle, etc.

Liang Yangang had seen similar data charts in the past, but never so detailed.

The flight trajectory of a traditional ballistic missile is relatively rigid and is completely determined once the launch coordinates and target location are determined, so there is no need to analyze such complex problems.

His heart moved, and he thought of the control surfaces at the back of the "Xuanniao" aircraft, and made a bold guess:

"This missile can also change its trajectory during flight?"

Then, he saw Xing Muchun's surprised look.

Liang Yangang suddenly recalled the time when he was in middle school. The naughty boy performed exceptionally well in an exam and came first in the class, and his head teacher gave him a similar look.

The meaning is probably "So you are not stupid, aren't you?"

Fortunately, Xing Muchun only glanced at him and turned his attention back to the screen:

"All parameters for the first launch have been calculated by us and set before the aircraft leaves the factory. It is no different from the Dongfeng-16 launch process you trained before... Even the process of inputting target location information can be omitted. All you need to do is avoid the reconnaissance of a few key satellites and move to the preset coordinates, then press the ignition button."

"But in subsequent tests, you will set the trajectory according to tactical needs... This process is assisted by computer software, but it is still more complicated than previous models. In addition, to a certain extent, the more perfect the preset functions are, the lower the tactical flexibility of the weapon is, just like..."

At this point, he paused and thought for a few seconds:
“It’s like assembly language and high-level languages ​​for computers.”

This description was of little value to Liang Yangang, but Xing Muchun himself looked very satisfied and quickly continued:

“So we need to know what the upper and lower limits of acceptance of these settings are for users… that is, you, so as to determine the development plan for the UI interaction interface.”
