Chapter 611
Just when many researchers were getting impatient.
Xu Hao suddenly raised his head from the encrypted computer and breathed a sigh of relief.
Seeing this, everyone looked at him at the same time.
Everyone wanted to know, facing such a problem.
As the chief engineer of the cross-media aircraft project, what kind of reaction and choice would Xu Hao make.
Feeling the earnest attention of many researchers.
Xu Hao stood up and put the new plan designed by the old professor on the big screen with ease.
Without too much nonsense, he started to explain directly.
"The new scheme adopts a step-by-step low-speed vertical water entry method for guidance, in simple terms."
"This method is mainly based on trajectory tracking guidance in the vertical direction and horizontal direction."
"That is, a medium-crossing trajectory is pre-designed according to combat requirements, and then the trajectory is tracked using relevant control methods."
"In this regard, commonly used control methods include proportional-integral-differential control, robust switching control, etc."
"In addition, we are based on..."
At first, the researchers were a little confused.
Everyone thought that Xu Hao would give the conclusion and reason for which scheme to adopt after analysis and deduction.
But now, why did he suddenly start to introduce the technical methods in the new scheme?
Although most people were a little confused.
But with Xu Hao's explanation, many people gradually abandoned complex thoughts and emotions.
Instead, they chose to listen carefully to the explanation.
Among them, the old professor who proposed the new cross-medium aircraft guidance method sat in the front.
Looking carefully at the blackboard and calculation formulas listed by Xu Hao through reading glasses.
From time to time, he would compare it with his own notes.
He nodded thoughtfully from time to time.
He obviously listened very seriously and carefully.
As the designer of the new scheme, he was naturally different from other researchers.
He could understand and analyze anything Xu Hao taught in a simple and easy-to-understand way.
And he could expand and extend it to a certain extent.
Xu Hao's explanation continued.
After a relatively comprehensive introduction to the step-by-step low-speed vertical water entry guidance method designed by the old professor.
He casually listed the old scheme he designed on the big screen.
And began to compare the differences between the two.
"From this, we can clearly see that the step-by-step low-speed vertical water entry guidance method has relatively low structural requirements for the aircraft."
"But I don't know if you have noticed that its transition process takes a long time and the take-off and landing distance is also relatively long."
"Overall, it can only be applied to scenarios where time requirements are not high and the take-off and landing waters are relatively open."
"This is its limitation. It is difficult to adapt to mission scenarios such as emergency military operations where the transition waters are narrow and the entry position requires relatively precise missions."
"So, the new plan has certain limitations..."
Hearing this, the scene was silent.
The old professor unconsciously exerted force on the palm of his hand holding the cane, and his eyes widened a little.
Feeling extremely shocked!
He designed the step-by-step low-speed vertical water entry guidance method.
But he didn't find its limitations directly and clearly like Xu Hao!
If so, his guidance method is indeed not suitable for many mission scenarios.
It can even be said that he designed such a plan under ideal environmental conditions.
But in the real combat environment, such an ideal scenario often does not exist!
Not only the old professor, soon.
Several sounds of gasping for air were heard at the scene.
Many researchers were shocked and surprised!
Originally, most of them chose to adopt the new solution.
They felt that after testing, there was no problem with this solution and it could perfectly adapt to the performance of the cross-media aircraft.
But now, Xu Hao only spent half an hour.
He immediately discovered its almost fatal limitations!
If this problem was not discovered, if they really adopted the new solution for the next research and development work.
I am afraid that they will have to wait until the test phase of the cross-media aircraft to find the problem!
And at that time.
Only by overturning everything and re-studying!
Thinking of this, the researchers swallowed hard.
Taking a deep breath, they all felt a little chill on their backs.
Xu Hao's proposal and analysis of this problem are too critical!
Hearing the commotion below, Zeng Xinghua and Wang Defa looked at each other and couldn't help but feel frightened.
Even they, after two days of studying the new plan without sleep or food, still didn't find this problem!
Or, was itPreconceived ideas blinded their eyes.
Instead, they ignored the more obvious practical needs.
However, in this way, hasn't it been determined which plan to choose?
The problem is...
The two looked at Xu Hao with doubts.
He looked calm and indifferent, and was still seriously comparing the differences between the new plan and the old plan.
Soon, more and more people realized that something was wrong.
They all felt a little puzzled for a while.
However, out of respect for knowledge, they chose to listen quietly.
Xu Hao continued to explain.
"In my design, a direct and fast oblique entry and exit method is adopted."
"This method can be well adapted to the emergency military action scenario I just described, because it has advantages in entry time and take-off and landing distance."
After a slight pause, Xu Hao tapped the table with his fingers.
The researchers who often listened to his lectures all realized that this was the key point.
Everyone was more focused and looked forward attentively.
Seeing this, Xu Hao smiled and continued to explain.
"However, this solution has high requirements for the structural strength of our cross-medium aircraft and the impact resistance of sensitive components."
"Although the water entry speed can be reduced through ballistic design, or the water-facing area can be reduced through variant design to reduce its impact force."
"But overall, it can only be said to be unsatisfactory, with certain limitations, and cannot perfectly bring out the advantages of the cross-medium aircraft."
As soon as this was said, everyone present.
Whether it was Zeng Xinghua, Wang Defa, or the old professor.
All dumbfounded!
After all, how did it become that both solutions have limitations? !
Then which solution is used for the guidance of this cross-medium aircraft?
How can the project work continue? !
The researchers were completely confused, looking at each other, with question marks all over their heads.
? ? ?
Originally thought that Xu Hao came, the problem of which solution to adopt could be solved.
Even the project work that had been stagnant for several days could continue.
As a result, Xu Hao came.
He perfectly solved the problem of which of the two solutions to adopt.
But how could he reject both solutions while talking so eloquently? ?
I don’t understand, but I am shocked!
