This is the history of the rise and fall of the variable sweep wing. Although it declined twenty years ago, its influence and value have not really disappeared.
Extremely high range flight envelope,
It perfectly balances high-altitude, high-speed and low-altitude subsonic maneuvers.
Effectively improve comprehensive flight performance.
This is the main advantage and value of variable sweep wings.
"1.35 and 0.94..." Kadar's eyes suddenly lit up, and he silently recited this set of extremely dazzling thrust-to-weight ratio data. After half a second, he quickly reacted, staring at the CF-26 'Panda' fighter jet on the big screen, and finally understood. Where does the so-called familiarity appear?
This concept aircraft plan uses a combination of variable sweep wings and canards, which is like a combination of the F-14 'Panda' fighter jet and the J-20 fighter jet.
Familiar yet strange!
No wonder, when Kadar saw the CF-26 'Panda' model pattern, he always felt that there was something similar, but he couldn't find the key point.
The reason is precisely here.
"It looks like the child of a panda and a Veyron. Great Huda, forgive me for this comment, but it is indeed too similar." Saleh, the top pilot of the Iranian Air Force sitting next to him, looked at the Panda concept aircraft plan and give an evaluation.
"As long as it's advanced enough, that's enough." Another top pilot stared straight at the big screen, as if he was looking at a peerless beauty and couldn't take his eyes away for a moment, almost drooling.
So beautiful.
This fighter jet immediately touched his heart. It has the beauty of the F-14 Panda and the charm of the J-20 Veyron.
Alberts remained silent, silently watching Cao Pingan and the CF-26 'Panda' on the big screen, and sighed in his heart: "It's incredible. There are so many excellent fourth-generation aircraft designed by the Chinese, one after another."
"Through effective aerodynamic processing, the Panda concept aircraft plan takes into account stealth performance while ensuring maneuverability. The design concept is to parallel stealth and maneuverability. The stealth performance is benchmarked against the F-22, and the maneuverability is on par with the J-20. It has excellent Compared with the F-35 and Su-57, it ranks first in overall performance, both are better than the four mainstream stealth fighters currently in service, and meets the design specifications of the fourth-generation stealth fighter. This is a real Panda fighter, and the Panda is honored as a national treasure of China. Fighter plane.”
After the Iraqi friends gradually digested the comprehensive performance and other contents of the CF-26'Panda', Cao Ping'an, the chief designer of the structure department, smiled slightly, and then threw out the core performance index to measure the quality of the concept machine-the design concept.
Ranked first in overall performance!
Relying on the advantage of being a latecomer, and drawing on the excellence of two famous aircraft, the F-14 'Panda' and the J-20 'Vyron', the CF-26 'Panda' Panda Concept Plane achieves a true comprehensive overtake.
Surpassing the J-20, punching the F-22, kicking the Su-57, suppressing the F-35, ranking first.
Well, although the Panda fighter is still on the drawing board.
"Bah bang bang!"
Suddenly, a round of loud and warm applause suddenly sounded, interrupting Cao Ping'an who was about to continue speaking. Looking around, he saw that the source of the applause was none other than the entire Iranian Air Force delegation.
applaud.
The warmest applause is given to Cao Ping'an and the CF-26 'Panda' concept aircraft plan.
Kadar and the messenger Alberts were completely moved. They couldn't stop applauding with their hands, and their eyes could hardly be separated from the noble and proud Chinese panda. There were blazing flames burning in the depths of their eyes, exuding heat and desire.
Sincere desire!
The Dark Halberd makes people excited, and the Rain Dragon makes people fearful. Now, this Chinese Panda makes them long for it, and they can't wait to have it right away.
Great Huda, this has comprehensive performance that surpasses the F-22 and J-20!
As long as they choose the Chinese Panda at this moment, then it won't be long before the remaining American Panda fighters in Iran will be replaced by real Panda fighters.
panda.
Chinese panda!
What an exciting title.
In the whole world, only China’s pandas are genuine pandas!
Kadar admitted that he, who was already in a state of excitement, could no longer hold back his excitement at this moment.
There is a desire deep in the body, coming from the instinct of a top pilot, which is telling a strong message - he wants this fighter plane and needs this fighter plane!
"Thank you all, thank you all my friends from Iraq."
There was a wave of applause. Looking at this group of excited Iranians, Cao Ping'an smiled politely. After a few seconds, the applause gradually weakened. He thanked him softly and started explaining again: "Next, we will explain the basic performance of CF-26'Panda' Design indicators - maximum range of 4,500 kilometers, combat radius conversion ratio of 0.44, combat radius of 1,980 kilometers, maximum flight altitude of 25,000 meters, maximum flight speed of Mach 2.5..."
The rich and gentle voice echoed in the huge conference hall, and the basic performance design indicators and parameters of the CF-26 'Panda' concept aircraft entered the ears of everyone participating in the meeting.
The little-known ultra-high combat radius conversion ratio of 0.44, the stable and realistic combat radius of 1980 kilometers, and various basic performance parameters are presented one by one.
The group leader Kadar, the envoy Alberts, the accompanying pilots and the aviation technical team were as attentive as students, listening carefully and not daring to do anything offensive.
Comprehensively understanding and mastering the performance of the CF-26 'Panda' concept aircraft plan and selecting a truly outstanding fighter aircraft for the motherland are the mission and responsibility carried on the shoulders of every Iranian present.
Academician Yang Wei is elegant and easy-going, adding a few words from time to time to explain the doubts to the other party.
Our own air force generals and Lin Jian and others listened with interest. The Air Force had long known about the three fourth-generation aircraft plans in the Chengdu Aircraft Concept Model Reserve. In this aircraft model review meeting, the three fourth-generation aircraft plans passed the Air Force's strict Participation is only allowed after evaluation and review.
The three fourth-generation aircraft plans each have their own merits. If we want to judge the strengths and weaknesses, the third Panda is the strongest, followed by the Yulong and Dark Halberd. As for the Z-1 concept aircraft plan that has not yet been launched, we will not comment on it for the time being.
In the entire conference hall, the atmosphere of the review meeting was extremely harmonious.
Fifteen minutes later.
"The CF-26 'Panda' is currently in the theoretical design improvement stage. It has run through the Mach 1 supersonic wind tunnel and the experiment was successful, verifying the feasibility of the aerodynamic layout of canard + variable sweep wing. However, we are not sure about the variable sweep wing. The mastery and understanding are not deep enough. If our Iranian friends choose this concept aircraft, we hope to be able to contact and study the F-14’s wing box receiver in the field.”
After comprehensively explaining the CF-26 'Panda' concept aircraft plan, Cao Pingan, who completed the task, turned his head to look at the Chinese panda that he was extremely obsessed with, glanced at it affectionately, then turned to face the Iranian delegation seat, and said in a serious voice:
"To sum up, I think this concept aircraft is a fourth-generation stealth fighter with excellent performance, which fully meets your needs. It is expected to have a development cycle of 20 years and enter mass production in 2040."
"My report is complete, thank you all."
After finishing his words, he bowed slightly according to etiquette to express his courtesy, and then Cao Pingan went to the seat.
"Bah, bang, bang!" Applause rang out, followed closely by Cao Pingan, who was walking steadily, and both China and Iran applauded.
"It's my turn." Seeing Cao Pingan, who was high-spirited and exuding the temperament of an aviation person, Zuo Xue clapped with both hands and gave applause to Cao Pingan, chief designer of the structural department, with a gleam in his eyes, revealing a sense of expectation.
