Chapter 221: Get It Done Within a Month

This is no simple set of data; it is clearly a technical treasure trove so complete it's monstrous!

In his mind, he not only had clear blueprints, but even the material composition, heat treatment methods, and surface processing techniques for every single component were perfectly clear.

He suddenly pulled out a stack of white paper and began drawing frantically.

The pencil in his hand was almost smoking; blueprint after blueprint was born under his hand, from the contour of the engine's compressor blade to the aerodynamic shape of the wings, and then to the ammunition feed mechanism of the autocannon—every stroke was precise to the point of near-paranoia.

Time slipped away unnoticed; when the sky outside the window turned from deep blue to gray-white, Li Mingyuan finally put down his pen and rubbed his wrist, which was on the verge of cramping. On the table lay a dense pile of blueprints; a rough count showed at least a hundred.

He picked up the first blueprint, which was the general structural diagram of the WP-5 Turbojet Engine.

This engine is the heart of the J-6, with a maximum thrust of 2,700 kilograms; although it is practically a primitive stone axe compared to the turbofan engines of later generations, it is top-tier technology for this era.

It has a 7-stage compressor, a combustion chamber with an annular structure, a single-stage turbine, and a thrust-to-weight ratio of about 4.1, making its performance comparable to the Polar Bear's VK-1 engine, but with an advantage in reliability.

Li Mingyuan gently stroked the blueprint, recalling the data he had seen in his previous life.

Although the J-6 was a copy of the Polar Bear's MiG-19, it had undergone independent improvements by the Dragon Country aviation industry, especially with significant enhancements in high-altitude performance and weapon systems.

After entering service, it remained the main fighter of the Dragon Country Air Force until it was gradually retired much later.

During the war, the J-6 engaged the enemy's F-4 Phantom fighters many times; although there was a clear generational gap in overall technology, it still achieved many results thanks to its excellent maneuverability and the bravery of the Dragon Country pilots.

He picked up the fuselage structure diagram again.

The J-6 adopts an all-metal semi-monocoque structure, a mid-wing design, a sweep angle of 45 degrees, a wingspan of just over 9 meters, and a fuselage length of about 14.5 meters.

This design has excellent stability during supersonic flight while maintaining good maneuverability.

Looking at the weapon system, what excited Li Mingyuan the most was the 30mm autocannon system.

This large-caliber autocannon has astonishing power, capable of firing 550-650 rounds per minute, with a muzzle velocity of 850 meters/second and an effective range of nearly 2000 meters.

This is absolutely a sharp weapon in air combat, especially when dealing with the enemy's Bomber, where it is almost a one-hit kill.

The PL-2 Air-to-Air Missile is another technical highlight.

Although in his previous life this missile would not be successfully developed until more than a decade later, with the technical data provided by the system, Li Mingyuan believed that a prototype could be launched ahead of schedule after significant simplification.

Although the PL-2 is only a simple infrared-guided short-range dogfight missile with an effective range of only 7-8 kilometers, it is absolutely an epoch-making weapon for this era.

"Chief Engineer? Are you alright?" The laboratory door was pushed open, and the assistant Xiao Wang poked his head in with a worried look, "You haven't come out all night, everyone is worried..."

His words came to an abrupt halt because he saw the table full of blueprints and Li Mingyuan's face, which was exhausted from staying up all night yet abnormally excited.

"Xiao Wang, go quickly and call everyone from the Hexin team," Li Mingyuan's voice trembled slightly with excitement, "Tell them I have a major discovery! Immediately! Right now!"

Xiao Wang was stunned for a moment, then nodded quickly and ran out.

In less than half an hour, a group of sleepy-eyed but spirited engineers gathered outside the laboratory door.

"Come in, all of you come in!" Li Mingyuan opened the door, his excitement hard to hide, "I want to show everyone something good!"

The engineers filed in, and when they saw the pile of blueprints on the table, everyone was stunned.

"This is..." Engineer Lao Liu cautiously picked up a blueprint and pushed up his reading glasses, "Turbo... Turbojet engine?" His voice rose suddenly, "Holy crap, this is a complete design drawing for a turbojet engine!"

"Not only that," Li Mingyuan smiled and picked up a stack of blueprints, unfolding them in front of everyone like a magic trick, "This is the entire set of technical data for a supersonic fighter; I've named it the 'J-6'!"

The laboratory immediately erupted.

"This is impossible... this is too complex... how did you... alone... overnight..." Zhang Gong stammered, unable to piece a few words into a complete sentence.

"Chief Engineer, the precision of these blueprints is simply mind-boggling!" Wang Gong carefully touched a cross-section diagram, "Every detail is so perfect, even the tolerance markings are so precise..."

"Is it theoretically feasible?" Li Mingyuan asked directly; he knew that although these veteran engineers had never seen a complete design for a jet fighter, their basic theoretical knowledge was absolutely solid.

Lao Liu held the intake design diagram of the WP-5 Engine, calculated it carefully for a moment, then looked up, his eyes flashing with a near-fanatical light:

"Not only feasible, but... but this is simply a genius design! The angle of these blades, the design of the pressure ratio, the structure of the combustion chamber... every part has been precisely calculated; I have never seen such a perfect design!"

The other engineers nodded one after another; although they could not understand how Li Mingyuan had completed this complex design overnight, as experienced professionals, they could judge the professionalism and feasibility of these blueprints.

"What is the performance of this fighter?" Zhang Gong asked, his eyes flashing with anticipation.

Li Mingyuan cleared his throat and began to introduce it in detail: "The J-6 has a maximum flight speed of 1150 kilometers per hour, approaching the speed of sound, a service ceiling of 【missing value】 meters, and a range of 1400 kilometers. The weapon system includes three 30mm caliber Vulcan autocannons, each capable of firing 550 to 650 rounds per minute. Additionally, it can carry the PL-2 Air-to-Air Missile that we are about to develop, which is an infrared-guided short-range dogfight missile, or it can carry conventional bombs for ground attacks."

"Meters?" Zhao Gong gasped, "Doesn't that mean it can easily intercept the enemy's U-2 Reconnaissance Plane?"

"That's right," Li Mingyuan revealed a mysterious smile, "And not just intercept; the J-6's firepower is enough to tear a U-2 to shreds in seconds. Its avionics system includes a simplified version of a Search Radar that can detect targets from 30 kilometers away, so even if enemy planes hide in the clouds, they have nowhere to hide."

The laboratory fell into a shocked silence once again.

"This... this is too revolutionary!" Wang Gong finally found his voice, "With this kind of fighter, we can not only defend the airspace of Taiyang, but even form an aerial deterrent against Di Guo!"

Li Mingyuan nodded: "But I must remind everyone that although the design drawings are finished, there is still a long engineering process between the blueprints and an actual flying prototype. Especially the engine; this is the most core and complex part, and it will require overcoming countless technical difficulties."

He paused and looked around at everyone: "I plan to divide the project into several stages: the first stage will focus on tackling the WP-5 Engine, which is the key to the entire project; at the same time, we will carry out the fuselage structural design and material preparation. The second stage will begin the assembly of the prototype and ground testing. The third stage will involve test flights and performance adjustments. If everything goes smoothly, within 1 month we will be able to see the first J-6 soaring in the blue sky!"
