"Five, four, three, two, one! Explode!"

"Bang~~boom~~!" With the commander's order, a slight explosion sounded in the center of the test site, and then a small cloud of mushrooms with dazzling lights rose...

Seeing the bright mushroom cloud gradually expanding, growing bigger and dissipating with the wind, Lu Jiadong, who was standing in the safety area, put down the telescope in his hand and smiled at Hu Qinghua behind him:

"Following the shape of this explosion, it should be said that the general direction of the agent formula developed this time is not wrong, but..." Lu Jiadong said, unable to help but pick up the preliminary test data and looked at it. Then a trace of doubt flashed in his eyes, and then his brows frowned slightly:

"However, judging from the data of these proportional tests, this temperature and pressure potion is not stable enough, and the power level does not have a constant value!"

After hearing Lu Jiadong's words, Hu Qinghua's brows couldn't help but frowned into the word "chuan", and a hint of fatigue flashed in his thin cheeks. In order to find a suitable warm-pressure potion, Hu Qinghua can also conduct data calculations and drug tests day and night for these days, and the entire development team and the test site ran on both ends.

In the long run, his body was originally quite medium, but now he has become thinner, but even so, he still put his whole mind on the development of the warm-pressure bomb. Although he has achieved certain research results, his views are just like Lu Jiadong, and he is still a little dissatisfied with this potion:

"I explored and tested nearly a thousand kinds of agents before finally determining this formula. From theoretical calculations, the viscous explosive shape of this set of ammonium nitrate-containing aluminum powder is the most reasonable value that meets the current technical and tactical indicators!"

But as he spoke, Hu Qinghua showed a faint helplessness on his face: "With the proportional explosion test, although this potion can achieve the effect of a temperature-pressure bomb, it is still a certain gap from the power value specified by our technical and tactical indicators. Not only that, the stability of this potion is not enough..."

"But no matter what, we have touched the general direction right!" Before Hu Qinghua finished speaking, Guo Qingshan, who was standing next to Lu Jiadong, also lowered the telescope in his hand. Although his face was filled with the joy of the first trial, he encouraged Lu Jiadong and Hu Qinghua beside him:

"This few trials have had some preliminary successful experience. Although I don't know much about technology, according to my perspective, this ammunition has high tactical value and application prospects. If it can stabilize its performance and increase its power, it would be better. If not, even if this set of temperature and pressure potion is applied to the front line, it will be enough for a monkey to drink a pot!"

Guo Qingshan is right. Judging from the tactical application, although this potion lacks stability and power, it does not affect its ammunition power exceeding the same quality and level, nor does it affect its application on the battlefield. From this point of view, the warm-pressure warhead potion developed by Hu Qinghua is considered successful.

But even so, Lu Jiadong was still a little dissatisfied with the power of this potion. There was no other reason, just because the Vietnamese troops who did not learn from monkeys and groundhogs on the Sino-Vietnam border. Thinking of this, Lu Jiadong leaned against the middle a few times:

"Use this warm pressure potion to deal with the Yue army's shallow tunnels and civil fortifications, and the observation posts are naturally indescribable, but the lethality of the Vietnamese army deep in the tunnel is somewhat insufficient. In other words, the high temperature and high pressure formed by the explosion cannot reach the deepest part of the tunnel, and it is even more impossible to use up all oxygen, and it is not achieved in the end our goal of attack!"

"This..." Although Guo Qingshan didn't know the principle of it very well, he also knew that what Lu Jiadong said was not just talking nonsense. One of the ultimate goals of the infantry tactical weapon system developed at present is to attack the Vietnamese army deep in the tunnel.

If this purpose is not achieved, then this portable rocket weapon system will not be considered successful at all. Because of this, Guo Qingshan's originally happy smile instantly sank after listening to Lu Jiadong's words, and Lu Jiadong turned his head to Hu Qinghua's side, flipped through the test report and continued:

"Qinghua! I think your thinking is still a bit wrong!" After hearing Lu Jiadong's words, Hu Qinghua's fair and thin face was stunned, but Lu Jiadong ignored these things and continued:

"From these values, you have indeed touched the path of the temperature-pressure bomb, both thermal killing and combustion are ideal. However, Qinghua, while you focus on thermal killing and consuming oxygen, you ignore another killing effect!"

"Chief Commander Lu, are you talking about shock waves?" Hu Qinghua deserves to be an expert in ammunition. After Lu Jiadong said this, he immediately answered. After hearing Hu Qinghua's words, Lu Jiadong couldn't help but nodded:

"Yes, it's shock wave! There are three basic characteristics of a thermocompression bomb. The initial anaerobic explosion reaction determines its high-pressure performance and its ability to penetrate solid targets; the anaerobic winding reaction after the explosion determines its pressure performance and its ability to penetrate walls and fortifications; the aerobic combustion reaction after the explosion determines its high-pressure impact and thermal performance, as well as its ability to damage personnel and equipment.

Judging from the characteristics of the above temperature-pressure bomb, the killing effect of the temperature-pressure bomb is mainly reflected in the high-pressure shock wave and thermal killing effect. This time, the fragments generated when the shock wave interacts with the building, as well as the suffocation caused by toxic gases and smoke. Among these killing effects, the most deadly thing for personnel is shock wave!"

"Shockwave?" After hearing Lu Jiadong's words, Guo Qingshan, who was standing next to him, couldn't help but frown in confusion, and then his eyes lit up:

"I remembered this. During the Liangshan Battle, our artillery fire was extremely fierce. Our division accompanied the artillery fire to attack the Vietnamese army. There was a very dangerous castle blocking our attack route. After several rounds of artillery fire were covered.

The castle was still intact. We were preparing to attack at that time, but when the soldiers who went up rushed over, they saw that the Vietnamese troops inside had already died. What's even more strange was that they had no external injuries at all. I was also very curious about this incident, so I went over and checked it out.

Unexpectedly, like the soldiers reported, the Vietnamese army's corpses were not only very complete, but they didn't even have any external injuries on their bodies. At that time, we only knew that these Vietnamese army were killed by our fierce artillery fire. It was not until after the victory that we told the artillery that we knew that the substance that shocked them was called shock wave!"

Although Guo Qingshan is not very proficient in technology, as the head of the army, he has rich battlefield experience. In his combat career, he has seen many such things as being stunned by explosions and being killed by artillery shells, so he has a more intuitive understanding of the killing effect of shock waves than ordinary people:

"If we can increase the impact wave efficiency of the thermopress bomb, I think that even deeper the tunnel will be like the dark castle I have seen before, and they will be killed by all the remaining ones!"

"Chief Guo is right!" As soon as Guo Qingshan finished speaking, Lu Jiadong nodded in agreement: "What's more, the killing effect of the thermopress bomb in open space and closed space is very different. Although the thermopress bomb can also be used as high-power ammunition in open space, compared with the enclosed space, the overall efficiency is much inferior to that in closed space..."

"Chief Teacher Lu, what do you mean..." Before Lu Jiadong finished speaking, Hu Qinghua, who was standing beside him, seemed to have figured out something, and the gloomy face on his face also showed a little smile:

"The fireballs and shock waves after the explosion of the thermostatic bomb spread along the tunnel and into places that ordinary bomb fragments cannot reach. The fragments of ordinary bombs may be blocked by tunnel bunkers, sandbags, walls or other protective devices, while the shock waves will be strengthened by reflections from the walls and other surfaces of the tunnel."

As he spoke, Hu Qinghua couldn't help but show an excitement on his face, and his tone gradually became excited: "In this way, at the same distance, people in the enclosed space will suffer much more intense shock waves than open spaces, thereby completely eliminating the enemies hidden deep in the tunnel!"

Hu Qinghua is worthy of being a military technical genius. Lu Jiadong and Guo Qingshan only pointed out the shock wave and its killing effect. Hu Qinghua immediately understood the importance and basic principles of shock waves in temperature-pressure bombs. This strong understanding and comprehension ability of ordinary people, even Lu Jiadong, who traveled through time in later generations, could not help but throw praise to Hu Qinghua:

"That's right! This is the core of the temperature-pressure bomb! Qinghua, in fact, among the many drug tests you have done, there are also many ratios that can increase the temperature-pressure effect!"

"As he said that, Lu Jiadong picked up the stack of heat-pressure bomb technical information next to him again, looked through it twice, found a drug ratio table, and then followed Hu Qinghua and continued:

"For example, this one, you used explosives based on Black Sorkin and combined with polystyrene as solid fuel. In fact, this is a good idea. However, Black Sorkin's explosive properties are slightly less intense and chemically unstable. If it were Okto, and then added polystyrene with powders of metal aluminum and magnesium..."

"Okto, mix aluminum magnesium powder?" Before Lu Jiadong finished speaking, Hu Qinghua felt as if he had discovered a new continent. He was full of energy, his eyes widened, and his murmured inexplicably excited, and he couldn't help but slapped his thighs hard:

"Yes! Octor, mix aluminum magnesium powder! Why didn't I expect this idea to be so powerful..." As he said that, Hu Qinghua patted his head with an excited and regretful look:

"Oh, look at my head! I can't even think of such a good potion, Oops..."

But before Hu Qinghua finished speaking, he hurriedly ran to the temporary office in the test yard. Guo Qingshan was very confused when he saw this. He was about to ask, but was stopped by Lu Jiadong beside him. His tone was even more confident:
Chapter completed!
