Chapter 746 Guidance is one thing, but a firm stance is still necessary.
Just as Lao Wang and Company Commander Tang went out to uphold justice...
Jiang Xia also suppressed Tianjiao in that small dormitory at the research institute.
However, the atmosphere here is quite different from that place called a small restaurant, which is actually the size of a basketball court.
There was coldness and despair there, but this small dormitory room of less than ten square meters was filled with a passionate, focused, and even somewhat excited atmosphere!
The desk in the dormitory was small, but it was piled high with blueprints. There were original structural drawings of the Il-28, as well as several sketches filled with new lines and annotations.
Jiang Xia and several young researchers sat together, their eyes shining, their faces showing the fatigue of staying up all night, but unable to hide their excited glow.
Through a series of questions and answers about their "secrecy rules," these young men miraculously established a connection.
That's how men are; after going through certain things together, they can quickly become closer.
However, this strange connection took a subtle turn when Jiang Xia pulled out the blueprints for the Il-28 improvement plan, which had been reviewed by Professor Guo.
In the sketch, the original Il-28's somewhat bulky high-mounted straight wing was significantly modified. The wing position was lowered, the sweep angle was increased, and the airfoil was also optimized. More importantly, four hardpoint pylons were added under the wings, and the original internal bomb bay under the fuselage was sealed off and replaced with newly added reinforced external pylons.
"You drew these blueprints? That's truly an unprecedented idea!"
"Unprecedented?" Jiang Xia looked up at the question, a playful smile playing on his lips. He pointed to the aerodynamic layout diagram of the Dongfeng-113 missile hanging on the wall. "Isn't that thing also 'unprecedented'? Isn't what we tech people do all about turning the 'unprecedented' into the 'right before our eyes'?"
“That’s true…” The burly foreman next to him frowned, pointing to a mark on the sketch, “Engineer Jiang, you’ve increased the wing sweep angle to 15 degrees and changed the airfoil to this type. According to the numbers, low-altitude high-speed performance will be improved, but what about low-speed takeoff and landing performance and stability? The 'Il-28' already has a long takeoff and landing distance. With this change, I’m afraid…”
Engineer Huang chimed in, with the meticulousness of a technician: "Yes! This design is too much of a change! The Il-28 was originally designed for high-altitude bombing. You've changed it to a low-wing monoplane, which may improve low-altitude stability, but what about the risk of flutter during high-speed flight? And this swept-wing design... for aircraft of this size, we lack wind tunnel data to support it!"
Jiang Xia shrugged: "Isn't that obvious? If I had any, would I have come all this way to eat dried radish here?"
"Oh, right!" Xiao Guan didn't mind being teased, he just scratched his head and chuckled.
These words stirred up Gu's competitive spirit. He stared at the blueprints for a long time, and then suddenly took out a "treasure" from his faded canvas tool bag: a bamboo slide rule about one foot long and three inches wide.
"Okay, you're good with words, let's let the data speak for itself!"
Have you ever seen a slide rule?
No? Great, that means I can swim again.
The slide rule is covered with densely packed, hair-thin logarithmic graduations on both the front and back, consisting of a main scale and a sliding scale. The main scale is fixed in place and is marked with graduations for different functions, such as A, B, C, and D. The sliding scale is embedded in a groove in the main scale and can slide left and right, also marked with corresponding graduations. At the top is a transparent vernier with a thin red line, which can move along the scale for precise readings.
Later slide rules were mostly made of plastic, but the one Xiao Gu used was clearly hand-carved.
Xiao Gu skillfully pinched both ends of the slide ruler with his thumb and forefinger, and with a gentle push, the slide ruler made a slight "rustling" sound in the groove of the main scale. After aligning the red line of the vernier with a starting point on the main scale, he began to carefully slide the slide ruler while silently reciting the parameters, and at the same time moved the vernier to position and read the value.
“Sweep angle 15 degrees… aspect ratio… relative thickness… angle of attack 15 degrees…” Xiao Gu muttered to himself, his fingers moving precisely between the scales.
"Check the lift coefficient CL... First, check the baseline value for this airfoil... then multiply by the sweep angle correction factor... then multiply by..."
The foreman next to him immediately got to work, taking out a small notebook and a pencil, ready to record the intermediate values and final results reported by Engineer Gu.
While watching Engineer Gu operate the system, he couldn't help but remind him, "Pay attention to the airfoil reference value. It was proposed by Engineer Jiang, but it's not in our database. We need to start the initial calculation again!"
Engineer Huang also came over to help check the position of Engineer Gu's sliding ruler and the reading of the vernier, afraid of misreading even one division.
Jiang Xia stood aside, watching with great interest as they operated this 1960s-era "human computer".
Looking at Engineer Gu's focused expression, as if he were having a spiritual conversation with the scale, and at the intermediate values that needed to be repeatedly verified by Engineer Guan, and then thinking about the series of problems they just mentioned, such as low-speed performance, stability, and flutter, that needed to be verified one by one... If this were done by using a slide rule to figure it out bit by bit, it would probably take forever!
Oh dear, how pitiful, not even one of Big Yellow's clones came to play.
So, the guy slowly pulled out the "Red Dragon's Eye" from his military green satchel. This "magical tool," originally made for project review, hadn't been put to use yet thanks to Yang Youning and his team's outstanding performance.
"Ahem!" Jiang Xia cleared his throat, successfully attracting the attention of several researchers. He shook the "square box" in his hand, his tone slightly smug: "Comrades, you've been working hard on these calculations, haven't you? How about... trying this?"
The four people opposite him looked up at the same time, their eyes all focused on the "iron lump" in Jiang Xia's hand.
"What...what is this?" The foreman stared wide-eyed at the box that gleamed with a metallic sheen.
"Calculator!" Jiang Xia said succinctly, his fingers rapidly tapping the keys. With a few soft "click-click-click" sounds, a string of numbers instantly appeared on the screen. "Look, addition, subtraction, multiplication, division, square roots, trigonometric functions... okay, it can do everything except trigonometric functions! As for the speed... it's a tiny bit faster than a hand-cranked calculator!"
"Faster than a hand-cranked calculator?!" Engineer Gu put down the slide rule in his hand, pushed up his glasses, and leaned closer to examine it carefully. "This... how do you use this? Can it calculate the lift coefficient?"
“Of course!” Jiang Xia handed the calculator to Engineer Gu. “Enter those parameters you were just talking about! Although it has to be done step by step, and it’s not quite as fast as Da Huang’s, but…”
The foreman took the calculator from Jiang Xia with some skepticism, but to him it looked more like an oversized brick.
It felt heavy in my hand, with a cool metallic feel. I carefully pressed the button, just like Jiang Xia did.
"1.25?!"
He abruptly grabbed the slide rule and the intermediate values he had just recorded on the table, and quickly readjusted, slid, looked up the table, and mentally calculated... A few seconds later, he looked up, his eyes wide, his voice trembling:
"It really is around 1.25! I... I haven't even finished calculating the correction factor yet! How... how can it be so fast?!"
"Things based on logic circuits are naturally fast... Uh, you guys haven't encountered Big Yellow's clone before?" Jiang Xia looked at the surprised expressions on their faces, which didn't seem fake. So he asked with a hint of doubt.
"I've heard of it! But never used it!" The three young men shook their heads rapidly.
“I’ve seen it, and I applied to the project department once, but I haven’t received a response!” Teacher Shunshou obediently raised his hand to answer.
Huh? Even the equipment factory that produces thermos bottles has been equipped with them, and your important unit hasn't even touched one yet?
It seems that the project team has really serious problems...
Thinking of this, Jiang Xia left the calculator to the poor students in the Seventh Institute to fiddle with on their own, walked out of the dormitory, and waved to summon Class Monitor Ru.
"Old squad leader, any news about Lao Wang and the others?"
"Not yet! Don't worry, those two won't get into any trouble. Let them wander around the border; who knows, they might bring you back a bear to eat..."
"You used a very good pun..."
It turned out that shortly after Jiang Xia and the researchers finished questioning each other about the confidentiality rules, Li Huaide called to report.
Over the phone, Li Huaide vividly described their experience of "playing a double act" in the project team, especially the decision not to rush to the warehouse for inspection.
Jiang Xia wholeheartedly agrees: With a different status, one must act with integrity and follow the "right path to crush all obstacles"! Auditing is something that must never be done in a crooked or unorthodox way.
After hanging up the phone, Jiang Xia went through the scenes from the anti-corruption drama several times in his mind, and decided to send Lao Wang and Company Commander Tang to "wander" around the small restaurant with the sound wave receiver.
What if we can record something? Art imitates life, and maybe we'll actually stumble upon a "classic scene" from a TV series.
"Let's wait a little longer." Squad Leader Ru patted him on the shoulder. "Those two are smart; they'll give a signal if something happens. Just do your work and don't let those parasites delay the important matters."
Jiang Xia sighed. Only after arriving at the scene did he realize how much pressure his motherland was under.
Although he is still some distance from the border, every few minutes, he can see several thick beams of searchlight piercing the night sky.
Each sweep felt like the malevolent gaze of a bear, lingering along the border, sending chills down one's spine.
We really need to speed things up and move beyond that overly ambitious "surpassing Britain and catching up with the US" approach. Let's build an "economical and practical" attack aircraft based on our existing capabilities.
In fact, before asking Teacher Guo to take a look at Jiangxia's set of drawings, it was already the result of him running through the "fault scanner" countless times.
Although it cannot simulate complex full-state flight parameters, it can quickly exhaustively search and screen the feasibility of countless modification combinations under the limited conditions it sets, eliminating those options that would lead to structural disintegration, insufficient power, or aerodynamic disasters, and ultimately retaining the solution that has the highest "cost-effectiveness" and is most likely to succeed under the current technological conditions.
To put it bluntly, he used his cheat code to take a shortcut, quickly finding the closest answer to the correct one from countless wrong answers.
My interaction with the colleagues at this research institute was merely an attempt to broaden their perspectives through this activity.
But time waits for no one.
Jiang Xia was prepared to force them to implement this improvement plan.
Let's leave the brainstorming to the "Qiang-5" (Qiang-5). The improvement plan for the Il-28 is settled!
(To be honest, there really weren't any searchlights in sight, and the address didn't match. But it's still necessary to obscure the geographical context.)
