Shocking.

Excited.

This is a set of effective and extremely useful fourth-generation aircraft offensive tactics, with extremely high reference value.

As Kadal thought before, no one can intercept a ghostly stealth fighter jet at an ultra-low altitude penetration of Mach 1.8.

Kadar's heart was ups and downs, as did two top fighter pilots affiliated with the Iranian Air Force.

"This tactic is very effective." Alberts nodded in agreement, remembering this high-value offensive tactic in his heart, and subconsciously glanced at the major general of the Chinese Air Force sitting on Yang Wei's left.

He didn't know why the Chinese Air Force revealed the high-value offensive tactics of this fourth-generation aircraft.

However, he knew one thing that he had to seize this opportunity and remember it with his heart.

"The CF-24 'Yulong' concept machine solution has completed theoretical design, improved aerodynamic layout, and blown through the Mach 1.5 supersonic wind tunnel that simulates low-altitude and ultra-low-altitude environments. The experiment is very successful and the design is verified. The overall lift coefficient index is 1.6."

After talking about the basic offensive process content disclosed by the Air Force authorization and permission, the entire CF-24 "Rain Dragon" concept aircraft plan was basically explained. Xu Yun, the chief designer of the pneumatic department, paused, and subconsciously pushed his glasses with his right hand. His face was confident and serious, and a hint of love appeared in his words, saying to the members of the Iranian delegation:

"Dear friends in the Iran, I believe that the CF-24 'Yulong' is an excellent fourth-generation fighter. If you choose 'Yulong', we are confident that we will complete all development work within 20 years and are expected to be put into mass production in 2040."

"My report is over, thank you everyone."

After the words came, Xu Yun bowed slightly to everyone and returned to the seat.

"Smack!"

In the conference hall, warm applause sounded like a tide. All 20 participants from our side and the Iranian Air Force delegation sent the warmest applause to Xu Yun, the main promoter of the CF-24 "Rain Dragon" concept aircraft plan.

Xu Yun returned to the seat and sat down again, and was full of energy. He glanced at Han Cheng, the deputy chief of the General Department sitting beside him, and smiled and looked particularly confident.

Compared with the CF-22 "Dark Halberd" with mobility as the core design concept, the CF-24 "Rain Dragon" is slightly bulky and has a relatively average mobility. The unique design concept of "Rain Dragon" makes the CF-24 "Rain Dragon" look extremely aggressive and has extraordinary competitiveness.

The ink-gray stealth fighter on the digital large screen outlines the fuselage lines that conform to the aesthetics of industrial design, exuding its own charm and temperament.

This is the rain dragon that Xu Yun likes and is obsessed with, the extremely unique and extremely aggressive rain dragon.

Looking at Xu Yun who was quite content, Han Cheng also smiled. He was not anxious to lose his composure, but calmly and calmly applauded with both hands.

"This Yulong design concept works, but it is still eclipsed in front of the J-20, and does not meet mainstream needs. It is suitable for regional powers and medium-sized countries, but also meets Iran's needs."

Sitting upright in the seat, Zuo Xue listened to the overall report of the Yulong Concept Machine, clapped her hands and gave Xu Yun an applause, while thinking about it, learning the valuable design concepts and angles in it, and giving her a sense of recognition.

A good scholar should use his strengths to make up for his weaknesses.

Zuo Xue learned valuable design ideas from this CF-24 ‘Rain Dragon’ concept machine solution. When the overall technology does not meet the standards, it is a trump card to adopt the idea of ​​taking a different approach.

First solve the problem of none, and then solve the problem of performance lagging.

Before this, you can use tactics to make up for it.

After a few seconds, the applause gradually fell.

"Please explain the third concept machine plan." Lin Jian's voice sounded again and spread throughout the conference hall.

After experiencing the profound physical and mental baptism of two four-generation concept aircraft solutions, the commanders of the Iranian Air Force delegation, Kadal and Alberts, were in their moods like riding a roller coaster, looking at each other and silently without saying a word.

The two of them calmed down their somewhat turbulent and surging emotions, returned to calmness, adjusted their collars, tidyed up their body shapes, adjusted their postures, and looked at them again in the big screen.

A group of aviation technicians and Iranian top pilots woke up from the aftertaste of the CF-24'Rain Dragon' concept aircraft solution, Mach 1.8 ultra-low-altitude penetration performance, with bright eyes and breathing in their breath. They were extremely looking forward to the last two mysterious concept aircraft solutions.

On the digital large screen, the CF-24 "Rain Dragon" concept aircraft scheme disappeared and became another new stealth fighter with black and gray cut stealth coating.

The round and short head has a smooth and streamlined fuselage, the iconic close-coupled canard, the slender edge wing, the medium-delta wing surface extending from the special thick part of the back of the fuselage, and the ends are inclined vertical tail and movable horizontal tail.

This is a stealth fighter that feels familiar but unfamiliar.

"Hello everyone, Hello, Iranian friends. My name is Cao Ping'an, the chief designer of the structural department. I am responsible for explaining to you the third concept machine plan, internal engineering number CF-26, code-named Panda."

On the right side of his seat, Cao Ping'an, the chief designer of the structural department wearing gold-framed glasses, stood up and came to the digital screen. He was tall and burly, with a look of about 38 or 39 years old. He briefly introduced himself according to the standard process, immediately tested the design and explained to the Iranian Air Force delegation:

"The Panda concept aircraft originated in 2000 and is also a backup design model of J-20, with a comprehensive performance enhanced version, single-seat and double-engine, and the power system is two WS-15 ‘Emei’ vector turbofan engines, with a total thrust of 362 kiloni, the whole machine's thrust ratio is 1.35, and the full load thrust ratio is 0.94. It adopts a canard wing + front wing of the fuselage + variable swept wing + tilted vertical tail + movable horizontal tail aerodynamic layout, with an overall lift coefficient of 2.0, and the DSI air intake design is adopted on both sides of the fuselage."

Unlike the copywriting that mainly emphasizes design concepts for the first two concept machines, as the main promoter of the CF-26 ‘Panda’ fourth-generation concept machine solution, Cao Ping'an prefers to talk about the comprehensive performance and power system of the body, as well as the thrust-to-weight ratio of the fighter most.

A thrust-to-weight ratio of the entire machine up to 1.35!

Full load thrust-to-weight ratio of 0.94!

This is the thrust-weight comparison data that several mainstream fourth-generation aircraft currently need to look up to. It easily surpasses the F-22 and J-20 and ranks first in the paper thrust-weight comparison data void.

As the spare tire behind the J-20's main palace, the comprehensive performance of the Panda concept aircraft is stronger than that of the J-20. The main scoring point is the legendary wing design that has undergone many twists and turns in history - variable swept wings.

The variable swept wings emerged in the 1960s and were initially ignored. Later, they experienced the trough of the F-111 fighter bomber known as the "widow-making aircraft", and the F-14 "Panda" and the Tu-160 "White Swan" strategic bomber, and finally fell into the popular stealth design concept at the end of the 20th century.
