At this moment, Chen Xuan and Xiao Rumu slowly walked to the small courtyard together amid laughter and conversation.

"I've seen the Steward. The maids and guards saluted one after another, and at the same time, they were extremely curious, wondering what the identity of the young man beside Xiao Rumu was.

Being able to walk side by side with Mr. Xiao and talk and laugh, they wanted to know with their toes that this young man's status was bound to be extremely high!

"Haven't you seen this person? Could it be that the offering has just arrived?"

"Offering? How is this possible! Our Xiao family's offering is at least expected to be achieved by the Super God of War!"

"He's still so young, how can it be an offering!"

............

Several maids and guards kept making eye contact, feeling more and more curious.

As for Chen Xuan and Xiao Rumu, they naturally went all the way to the direction where Xiao Yu was.

After a short time, the two of them had already come to Xiao Yu's side.

"Hmm, Uncle Rumu, why are you here?" Xiao Yu didn't get up, still sitting on the ground fiddling with the rocket model, just casually glanced at Xiao Rumu and Chen Xuan.

"Oh, yes. Xiao Rumu immediately smiled and explained, "This one is the new enshrinement of our Xiao family, Mr. Chen Xuanchen!"

"New Offering?" Xiao Yu's expression was hardly moved, "Even if it's a new Offering, then there's no need to come to me, right?"

"Young family master, Mr. Chen Xuan has already met with the family master. ”

Xiao Rumu followed up and said, "The reason why I will bring him to you now is because he has just taken over the task issued by the head of the family......

"Is that the quest to play with me?"

Xiao Yu suddenly showed displeasure on his face, pouted and said, "Uncle Rumu, I told you that I can't play with those martial artists!"

"So, go tell your father and delete that mission as soon as possible!"

"I don't need a playmate at all, so please let this Mr. Chen Xuan go, I still have to continue my research!"

............

These words made Xiao Rumu speechless, and she could only look at Chen Xuan in embarrassment.

And Chen Xuan, who had expected this situation for a long time, didn't care at all, just smiled slightly, and then took a serious look at the rocket model design drawings beside Xiao Yu.

You must know that Chen Xuanke is a real second-level martial arts equipment master, and his attainments in science and technology surpass Xiao Yu by several levels.

He only needs to glance at the content on the design drawing to quickly judge the shortcomings.

So, after reading it, Chen Xuan took his hand and said particularly casually: "Be reasonable, this research of yours is not very good......

"Hmm, Mr. Chen Xuan, you are extremely powerful and worship my Xiao family, but I'm afraid that you don't understand rocket design at all! So, please don't express your opinions on my works indiscriminately!" Hearing this, Xiao Yu suddenly frowned, and there was a faint anger in his eyes.

Although he deeply understands that his design is far from perfect, it is the "best solution" that he has researched for a while.

So at this moment, after hearing Chen Xuan's comments, Xiao Yu was very unhappy.

"Young master, you are wrong. ”

Chen Xuan shook his head lightly, and then said: "Since I dare to take on this task, I naturally have some involvement in science and technology. ”

"I can still see some ways in your rocket model design. ”

............

As soon as the words fell, Chen Xuan slowly squatted down under the gaze of Xiao Rumu and Xiao Yu in complete disbelief, picked up the rocket design drawing, and then said leisurely to Xiao Yu: "Young master, I will first talk about your wrong choice of nozzle and shell material and some flaws in the design......

"All in all, your model rocket does not make perfect use of aerodynamic forces, and once the ignition starts, it will experience extremely much resistance!"

"And the materials you use are all on the high density, so the quality is a little too heavy. ”

"Under the same thrust, its maximum flight range will be greatly reduced. ”

"Finally, let me focus on your problem with the solid propellant formulation!"

"In fact, although this rocket model of yours has shortcomings in all aspects, as long as it can solve the problem of solid propellant and fly at an altitude of 10,000 meters, it will not be a problem. ”

"The solid composite propellant you use is a sodium borohydride mixed fuel, which is also a high-quality fuel. ”

"It's just that with your current processing methods, it's not enough to fully utilize its burning energy. ”

"In the process of propulsion, more than 80% of its energy is lost in vain, and less than 20% is turned into propulsion power!"

"So, the most important thing to improve your rocket model at the moment is to develop a better solid propellant!"

............

Chen Xuan's words made Xiao Rumu directly stunned.

"Oh my God, isn't it? This Mr. Chen Xuan, how does it sound like he really understands technology?" Swallowing his saliva, Xiao Rumu immediately stared at Chen Xuan with a monster-like look, his eyes full of disbelief.

As for Xiao Yu, after listening to Chen Xuan's narration, his eyes naturally brightened and suddenly brightened.

"Mr. Chen, Mr. Chen Xuan, then you must know what kind of solid propellant is better, right?" At this moment, Xiao Yu looked at Chen Xuan with great anticipation, and there was no anger in his expression.

Yes, it's just recognition and worship of Chen Xuan!

The reason is very simple, what Chen Xuan just said, every sentence is to the point, is a flaw in the design of his rocket model.

It is also the crux of the problem that has plagued him every day for this period of time!

Therefore, in his opinion, since Chen Xuan can see through his design flaws so easily, then Chen Xuan's attainments in this area are bound to far surpass him!

Under such circumstances, Xiao Yu would naturally look at Chen Xuan differently and was very willing to ask for advice!

Even, even if he is now worshipping Chen Xuan as a teacher, there is no problem!

"There are many solutions that are better than your solid propellant. ”

After a while, Chen Xuan replied very calmly: "Well, let me tell you the simplest and easiest way to do it." ”

"As long as you mix T3 type water glue explosives into an existing solid propellant, you can create a flammable gel. ”

"It can produce more than 8 million N of thrust, which is enough to double or more the maximum lifting distance of your rocket model!"
