Genius is just the threshold for me!

"hiss--"

Upon seeing the aircraft blueprints, Wang Xingguo exclaimed, "Tailless delta wing + twin vertical tails, this could be used to make a large bomber?"

How do you address the challenges of low-speed takeoff and landing, limited range, and the vibration issues associated with this flight configuration?

As an aircraft expert, Wang Xingguo naturally recognized the layout of the tailless delta wing and immediately saw the defects and problems of this aerodynamic layout.

He originally knew that Lin Dong was going to build a supersonic bomber, and the design would adopt the variable-sweep wing of the Tu-160, since this design was almost the standard choice for all supersonic large bombers.

But I didn't expect it.

Lin Dong ultimately pulled out a tailless delta wing aircraft with twin vertical tails.

Using a tailless delta wing with a high sweep angle to take off a large bomber weighing over two hundred tons is a crazy idea.

"Godfather, this isn't the last century anymore. Electronic control technology is more advanced, and the performance of flight control computers has improved... If we remove the vertical tail, we can make a supersonic large bomber with a large-angle flying wing layout."

Lin Dong smiled and said, "But if structural stealth is too costly, then a flying wing layout is unnecessary. This tailless delta wing with twin vertical tails will suffice."

Lin Dong did not mention that the H-20 design, which was revealed more than a decade later, did not even have a vertical tail; it was a pure flying wing layout that achieved supersonic speed and stealth.

Technology is constantly advancing. Problems that were insurmountable in the last century for tailless delta wing supersonic large bombers have now been solved with corresponding technologies.

"Xiao Dong, the tailless delta wing + twin vertical tail layout, can it be used for stealth design?" At this moment, Lin Weiliang saw this flight layout and asked with some curiosity.

"Not really. Fighter jets are fine, but large bombers are too big. Only a flying wing configuration with the vertical tail removed will work."

Lin Dong shook his head: "However, this method can reduce most of the radar reflection. Combined with electronic stealth, it is actually several levels better than the stealth effect of conventional variable sweep wings."

For fighter jets, due to their small size, the twin vertical tail structure uses a unique outward or inward cantation design to reflect radar waves in other directions, reducing the lateral RCS (radar cross section) and thus achieving radar stealth.

However, large bombers are so large in size and shape that their vertical stabilizers also need to be much larger.

Even if the vertical stabilizer reduces lateral RCS through a unique angle design, the remaining signal can still be detected by radar.

"Because it adopts a tailless delta wing + twin vertical tail design, to solve the problems mentioned by my godfather, the engine uses a large-angle vector design, and with the current electronic control technology and flight control algorithm, it is sufficient to meet the requirements of low-speed take-off and landing."

The approximate parameters of the entire design are as follows: wingspan 35.6 meters, wing area 647 square meters, payload 22.8 to 37.8 tons, empty weight 95.8 tons, maximum takeoff weight 245.7 tons, fuel capacity 112.1 tons, subsonic and supersonic cruise capability, and maximum penetration speed Mach 2.4.

Because it uses a variable bypass engine, the engine's fuel efficiency can perfectly adapt to different speed ranges. At a subsonic speed of Mach 0.9, the cruising range can reach 15800 kilometers, and at a supersonic speed of Mach 1.4, the cruising range can reach approximately 11800 kilometers...

"15800 km/h subsonic cruise, 11800 km/h supersonic cruise..."

Listening to Lin Dong's account, Wang Xingguo was somewhat shocked and said, "Is this variable bypass ratio cycle engine really that amazing? This engine alone increases the range by more than 40%!"

As the chief engineer of Chengdu Aircraft Industry Group (CAC), Wang Xingguo was well aware of how short the range of tailless delta wing aircraft was.

If a conventional engine were used, with this takeoff weight and fuel consumption, the subsonic cruise range would be at most 11000 kilometers, and the supersonic cruise range would be at most 7500 kilometers. It would be impossible for both to exceed 10,000 kilometers like this.

"The usual rate is around 40%."

Lin Dong nodded: "I might be a bit better technically; this solution improved by about 44.7%..."

The variable bypass ratio cycle engine is a different engine structure from the previous variable cycle engine.

A variable cycle engine is a combination of multiple different engines.

With the help of a unique air intake design, the intake air is directed to the engine in the corresponding speed range at different speeds.

The variable bypass ratio cycle engine has only one turbofan engine.

However, through special geometric mechanical structures and unique intake fan blade designs, the airflow of the bypass duct can be changed, and the variable design of the bypass ratio can be adjusted.

For example, Lin Dong's engine design uses a three-speed bypass ratio design, with a mid-range bypass ratio of 1.32, a higher bypass ratio of 6.3, and a lower bypass ratio of 0.48.

This allows for maximum fuel efficiency during takeoff, landing, and subsonic cruise when speeds are relatively low, with a bypass ratio of 6.3.

At transonic speeds, a bypass ratio of 1.32 can achieve better fuel economy.

Once you enter supersonic cruise, using the minimum bypass ratio of 0.43 will still ensure the best fuel economy.

Because it can maintain optimal fuel economy at different speeds, a variable bypass ratio engine can easily increase the range by about 40%.

The previous generation of sixth-generation fighter jets used this engine design, and even with a maximum takeoff weight of 58 tons, the range could still easily exceed 8000 kilometers.

"This Red Ghost bomber, in addition to the basic bomber and missile platforms, also incorporates three additional platform designs, the first of which is a laser interceptor platform..."

After Lin Dong briefly introduced the basic parameters, he took a few documents and handed them to Wang Xingguo and the others, then opened an animated diagram.

A bomber was flying in the sky when suddenly multiple missiles attacked.

But the next second, lasers flashed on the surface of the bomber, and the missile exploded in mid-air when it was still 3 kilometers away from the bomber...

"The laser interception platform uses twelve high-power lasers, distributed in six different locations on the bomber, and six of them can be activated simultaneously for interception."

Equipped with an optical and radar tracking system, it can lock onto targets at a distance of 10 kilometers and destroy them at a distance of 3 kilometers.

Based on the Mach 6 tracking speed of modern air-to-air missiles, this system's interception response speed, depending on the enemy missile's angle of attack, can withstand a simultaneous attack of 6 to 18 missiles.

"Xiao Dong, you mean at the same time?" Xu Ziming noticed Lin Dong's description and couldn't help but exclaim.

"Yes, 6 to 18 missiles simultaneously..."

Lin Dong nodded and calmly said, "This is a static platform, which is the data of a bomber that is not moving."

If combined with electronic jamming of missiles, and the bomber's own maneuvering to evade detection.

Actual interception data is expected to improve by approximately 100% to 200%, but the exact extent of the improvement will only be determined after the aircraft undergoes offline test flights.

"Oh My God--"

Wang Xingguo's eyes widened, his expression filled with ecstatic joy. "What's the point of stealth design then? Just add some interceptor lasers, and wouldn't we be able to bombard enemy missiles right above their heads?"

"...Godfather, don't make any wishes."

Looking at Wang Xingguo's ecstatic expression, Lin Dong said speechlessly, "The current power supply system can only provide enough power for six lasers to intercept the launch at the same time. We can't afford to add any more lasers."

Six doors were activated simultaneously, but twelve laser launchers were deployed to account for scenarios where the enemy could launch multiple missiles simultaneously from the same location.

One group can intercept two missiles, and the other two groups can adjust their angles to intercept four more.

"That makes sense. Such a powerful laser must have a very high power output."

Wang Xingguo took a deep breath and asked seriously, "What about the two new platforms?"

"The second is the drone delivery platform."

As Lin Dong spoke, he opened the next animation, showing bombers flying dozens of kilometers above the enemy's position, and nearly 10,000 drones suddenly dropping down.

The unique aerodynamic structure design allows these drones to glide directly into the sky, tracing a parabolic trajectory according to the aerodynamic layout, and flying towards the position tens of kilometers away.

Once inside the firing range, the cameras and infrared detectors activate periodically, locking onto ground personnel or tanks and adjusting their trajectories.

Once gliding to within 400 meters of the target, the folded wings extend, the motors start, and it swarms towards the pre-locked target like a swarm of bees…

boom--

The entire position was instantly engulfed in explosions, while thousands of drones, having not been assigned targets, landed safely on the ground.

The next moment, enemy reinforcements arrived, and the drone leaped into the air, embracing them once more...

"..."

Upon seeing the entire animation diagram, all three members of Laboratory 78—except for Lin Weiliang, who knew about it beforehand and participated in the design—fell silent.

At last.

Wang Xingguo looked at Lin Weiliang, who seemed to have known all along, and then at Lin Dong, who looked calm and composed like a young man. He opened his mouth but remained speechless.

"Xiao Dong, there's a swarm of drones ahead, as well as combat robotic dogs, and now there's another airdrop drone."

"Does this infantryman... have some kind of grudge against you and your father?"

Modern bombers, in addition to air-launching long-range missiles from the rear, also drop aerial bombs and cluster bombs when they actually go to the front lines.

These bombs are incredibly powerful; each explosion creates a mushroom cloud and covers a vast area.

However, on the modern battlefield, soldiers are spread out over a wide area. These seemingly powerful aerial bombs may not even hit 20 people with a single 3-ton bomb. Even if larger cluster bombs are deployed, in most cases, the number of casualties will not exceed 100.

Therefore, modern bombers primarily target large buildings or fortified positions, rarely directly bombing infantry...

But Lin Dong modified it, turning it into a drone delivery platform that could be deployed directly to feed the infantry.

If such a bomber were to fly over, it's estimated that tens of thousands of infantry within a 20-kilometer radius would be wiped out.

If there aren't enough ground infantry to allocate to drones, the remaining drones can be deployed as close-range landmines, used for siege warfare and attacking reinforcements...

Even more outrageous is this gliding drone, which is clearly not the current swarm drone, but a new type of drone designed specifically for airdrops.

An additional drone was specially designed for airdropping bombs of infantry.

This is definitely a living Yama, the infantryman.
