Chapter 1332 How can we make hypersonic weapons with such a group of insects?
Jabolensky was already in the middle of a battle between reason and conscience, and the moment he took the initiative to talk to Collinger, he was already feeling dizzy.
Now that I was interrupted like this, it was impossible to directly admit that I had found something fishy in the testing process of the solid rocket booster after I regained my consciousness.
And as Dr. Hurst said before, the scramjet engine was successfully started and worked normally for a period of time. They should not have been found.
After such a self -evasion, the original sense of guilt in Jiablynsky's heart finally disappeared.
Don't ask, just ask if someone else did it too.
"Daniel?"
Of course, Collinjie didn't know a series of ideas that flashed quickly in his mind in front of him. He just watched Joberzuski, who seemed to be caught in the gods after he heard his answer, and re -called the other person's name.
Only then did the latter regain consciousness:
"Oh..."
Jabolensky quickly made an appearance of racking his brains:
"I was thinking, in the next stage of the research and development process, there is nothing we need to do."
This technical issue really attracted Collinger’s attention:
"Strictly speaking, we have only implemented the fault tree analysis and have not yet formed a complete conclusion report, so the new research task is not urgent..."
While signing Jobornsky to keep up with his own footsteps, he answered:
"But if you really want to start working quickly, then I suggest that you can focus on the parameter accuracy of further improve the solid rocket engine."
"Precision?"
Jobernisky is a bit strange to this adjective.
Compared with liquid propellants, the working characteristics of solid propellants are explosive, that is, the maximum performance of the propellant is exerted as much as possible.
If there is excess energy, it can be consumed by letting the flying body maneuver itself, or simply set up a flight condition detection gate to jettison the booster in advance once triggered.
Therefore, there is no need to consider too complicated control issues.
"Yes."
Collinger nodded:
"In order to further improve the work stability of the inhale engine, we may partially adjust the compressed air intake system of the 2nd and No. 3 test bombs ..."
"You should know that the scramjet engine relies on the pre-ignition-shock wave system to achieve air compression, and the working window of this system is relatively narrow. As a result, different air intake systems must correspond to different starting conditions. If the shock wave train affects The air inlet may break the balance between the air inlet pressure and the combustion chamber back pressure..."
"In short, you should frequently adjust the working curve of the rocket booster section later. If you can improve the design accuracy, you can save a lot of trouble of repeated testing."
A seemingly ordinary request suddenly set off alarm bells in Jablonski's head.
This is the content that I didn't mention it at all at all.
Logically speaking, if the heat sealing is not tight, you can just improve the sealing technology, or even more fundamentally, redesign the interface part and you will be done.
There is no need to involve the transformation of the compressed inlet system.
In other words, this little old man who seemed to be completely in the dark probably did not put everything he knew into the preliminary conclusion report.
Even if the other party is not clear about the specific problem, at least it has skeptical SJX61-1 ultra-burning stamping engine and inclusive company.
In this case, will it have been stared at myself, but because there is no evidence ...
Jobrenji suddenly had a cold back, and he was a little too dare to continue talking to Collinjie.
Instantly, I want to laugh again-
From this point of view, the major subsystems of the entire project are probably Wolongs and Phoenix. It is likely that others have done the same thing as themselves, but it is just hidden.
With such a group of worms, how can you do a good job of hypersonic weapons?
Oh, so I am also a worm?
That's okay.
At this time, the two just walked to a split intersection in the test center.
One side leads to the living area, and the other side leads to the park gate.
So, Jobrenzki quickly found a reason and said goodbye to the other party after saying goodbye to the other party ...
……
In fact, Collinje did not pay much attention to the problem of helping the machine.
Although the working time was not as expected and the flight body could not be advanced to the planned separation speed, the difference of only a single-digit percentage was still within the acceptable range, and there is still a further optimization range in the future.
What really makes him doubt is the conclusion of the two accident tree analysis-
Even if the actual heating situation is not accurately estimated during the design stage, the flight body variable variable exceeds the pre -pre -estimate, the problem should first be in the two positions of the airway and the burning room.
The analysis conclusion is that the installation mouth between the rear of the engine and the bomb body is not tightly sealed.
This is a bit outrageous.
And during the test, the data of the bullet -load signal sensor disappeared all in an instant. According to his experience, this is more like a flying body directly disintegrated after a flight body has an unknown structure or load problem.
If it is the reason for the slow knife cutting meat as high temperature gas, then the sensor data should first abnormal, and then the abnormal data gradually expands and finally disappear. And such an analysis conclusion is given by the two independent analysis teams.
Therefore, someone within the R&D team is definitely up to something.
As for who exactly...
He might find out soon enough.
Collinger watched Jabolenski's retreating figure, raised his hand to check the time, then turned around and walked straight towards the parking lot at the door.
As a project director and senior engineer, his actions are basically not limited.
Even if you leave the test center, you don’t need to declare it to anyone in advance.
About an hour and a half later, Collinger's Dodge pickup truck was parked in the underground parking lot of a hotel in downtown Wilmington.
Soon, a man from a suit and leather was quickly walked. After confirming the license plate number, he opened the door of the co -pilot and sat up.
"Karl, long time no see."
While Collin Jie grew up the volume of car music.
There is no mistake in every song, one post, one content, one 6 one, one book, one book, take a look!
Karl Heinz Brinkmann is a professor at RWTH Aachen University and director of the Fluid Mechanics and Aerodynamics Laboratory.
It was also the "foreign aid" specially found by Collingie.
The two attended the same university thirty years ago. Although Collinger chose to enter the corporate world after graduation, while Brinkmann continued to stay in academia, they have always maintained a close relationship.
At least to the former, his friend is far more reliable than most colleagues.
"Why choose to meet in this kind of place ... Don't you go up to drink a cup of coffee?"
Brillman frowned, obviously he didn't like the depressed environment of the underground parking lot.
Collinje didn't explain too much, just shook his head:
"Sorry, I really don't have time recently... When you finish the work at hand, I will invite you to sit on my farm."
"Okay."
The Blingman next to him obviously also understood his character, but shrugged, and took out a U disk from the briefcase he carried:
"The test data you want is all here."
After seeing the U disk, Collin Jie's eyes lighted up instantly, and he went to the back seat and took the laptop that had already been prepared.
However, Brillman did not immediately give the USB flash drive to him, but hesitated, and then said:
"I have to remind you first. Although the TH-D wind tunnel is already in the category of the high-lying wind cave, it is still unable to fully reproduce the flight conditions in the high supersonic state, especially the total temperature of the air flow, and is limited by a single test. The limitation of the cycle will also have some distortion for the measurement of some cumulative parameters. If you want to use it as an engineering needs, it is best to only be used as a reference ... "
Collinger couldn't help but curled his lips:
"It's not my first day in this line of work, don't worry..."
As an experienced engineer, he certainly could not make such a stupid mistake.
In fact, he was just going to compare the data given by the TH-D wind tunnel with the design data given by Pratt & Whitney. It only needed to be six to seven times the actual total temperature, which was enough.
Brinkmann hesitated for a moment, but after all, he came here and finally took the initiative to insert the USB flash drive into the USB interface...
Kelingjie did not choose to copy the data, but opened the report document directly on the USB flash drive, then clicked on another origin data file on the desktop, and exported several PNG-formatted lines to the report document. Background vector curves.
This was a rather barbaric way of comparing data, but he didn't need a detailed analysis report this time anyway, so he didn't care about these minutiae.
"What is this?"
Brockman looked at the computer screen in doubt.
Collinje is dragging a few curves into the same chart at the moment. Because there is only a touchpad, the operation is quite awkward and the head is not lifted:
"The SJX61-1 engine design curve provided by Intelligence ..."
Just as he finished speaking, the starting points of the two curves were accurately overlapped.
It can be clearly seen that the entire curve has obvious differences after the abscissa axis ln (T9/T3) is greater than 0.3.
When reaching the critical point of 1, the corresponding Machi number had a gap of nearly 25%.
Brinkmann had just recovered from the shock of seeing such confidential data when he noticed the ridiculously large gap in results on the screen.
"You see, I have said it long ago, the measurement of cumulative parameters will be distorted ..."
Obviously, he hadn't realized where the problem was, and subconsciously thought that his wind cave data was not accurate enough.
"There is indeed some distortion..."
Collinger took a deep breath:
"But it's not that your data is distorted..."
"..."
At this moment, the same voice as Jabolensky echoed in his mind——
How can we make hypersonic weapons with such a group of insects?
