The three-meter-5-meter-high aircraft is pitch black all over, with smooth and round lines, like a huge cannonball with wings. The sharp airspeed tube that emerges from the front looks like a swordfish's thorn, flashing with a cold light.

This is simply a work of art that combines many peak achievements such as technology, industry, machinery and chemistry! Although it is almost unique in the world and cannot be mass-produced for many years, it does not prevent a bunch of top aircraft masters from appreciating and admiring!

A wet and cold wind gushed, shaking Wang Zhu and others who were sweating all over, and they woke up from their intoxication. Then they looked at Zhu Bin, climbed up the plane along the ladder, turned over and jumped into the cockpit to start the power supply. The nose and several cold lights on the wings immediately lit up. Under the high-power output of the high-energy battery pack originally used to drive the protective force field of the spacecraft, four small magnetic fluid generator injectors made a surging howling, and the four flat-long hexagonal nozzles emitted a high-temperature flame of more than 2,000 degrees more than four meters long!

Although they stopped just after squirting, Wang Zhu and others suddenly felt a sense of heat coming close to the steelmaking furnace. Their bodies were steaming and their hair was curled. They hurriedly retreated for more than ten meters in panic, and they were all shocked!

Zhu Bin gave them a thumbs up and gestured, and started the three-blade propeller engine. The guy who originally designed to burn gasoline suddenly injected highly gasified and expanded pure methane into the cylinder. The spark plug ignited strongly and exploded. Methane fuel, which was twice the combustion value of gasoline, pushed the eighteen pistons to run wildly, and a roar immediately swept the entire runway!

On the dashboard in front of the cockpit, the pointer representing the engine speed rushed from zero to horsepower! Zhu Bin excitedly waved his fist and continued to increase force, and watched the pointer continue to rotate right until the horsepower had exceeded the red line position. The status display of the sensor projected onto the hologram screen of his helmet was working normally!

The heavy plane could no longer stand still, and slowly glided along the runway. After three or five seconds, it suddenly accelerated. The two-kilometer long runway reached the end and slowly stopped.

The first time it was gliding normally!

Wang Zhu and others caught up in the car, waited for Zhu Bin to turn off the engine, climbed up with all his hands and feet, holding the instrument for a while, and checking and measuring it. After ten minutes, he confirmed that his condition was intact, he turned around and continued to slide!

After three or four hours of struggle, I have experimented with almost every power standard and hybrid propulsion method. The aircraft is surprisingly stable in a stable state, no matter the engine, circuit, oil circuit, compressor, power supply or instrument, there is no problem.

Zhu Bin decided to do his best to end the experiment as soon as possible even if he took the risk. With Wang Zhu and others' repeated instructions, he took a short rest and restarted the plane and slowly slid out about 200 meters. The head of the aircraft suddenly rose up and penetrated into the night sky like a sharp arrow, taking off as

Standing on the ground, Wang Zhu felt that the whole plane was like a festive monkey. The shining flames pushed the body upward at a steep angle of 80 degrees. The climbing speed was so high that it was unbelievable. In the blink of an eye, it was completely invisible! Only a burst of sharp whistlings passing by were heard floating back and forth in the sky, and Zhu Bin's excited cheers kept coming from his headphones!

"Hanchen, come on, take a moment and this is a new plane. At least it takes dozens of tests to ensure overall stability!"

Wang Zhu saw through Zhu Bin's temperament. As long as he was asked to fly into the sky, he would not expect to be obedient. In short, he would not stop without creating the ultimate performance of the plane. He was bold, skilled and experienced. Although he was the best test pilot, this method really tests the design and processing level!

Zhu Bin shouted indifferently on the radio: "Lao Wang, don't worry, don't you know the plane I designed myself? Every part has been tested and there will be no problem. Hahaha! The speed is up to kilometers, it's not bad, come again, come again!"

"760!" Wang Zhu couldn't help but shudder, excited and worried! Good guy, I didn't expect this strange plane to run so well. The speed was simply unimaginable!

Wang Xiaofeng also looked excited and murmured: "I heard what he meant, I haven't reached the limit yet. I really don't know what amazing speed would be if he had all his strength!"

While they were talking, they heard a louder howling from the sky, and a rumbling roar like thunder swept across the shipyard from east to west. It was almost winter. Thunder? No, it was the plane that caused it!

"He has already broken through the sound barrier, right?" Several engineers all know that when the flight speed exceeds the speed of sound 340 meters per second, a sound barrier will be formed at the head of the aircraft, and a sonic boom will be generated at the moment of breakthrough. Generally, the strength of the body cannot be withstand it, and maybe they will all fall apart!

However, in their opinion, that kind of aircraft is still very far away, and propeller aircraft is almost impossible to do it. Zhu Bin told them that if the aircraft increases the cylinders to 24 and the total power reaches more than horsepower, it can reach a flight speed of more than 800 kilometers. They are already very strong in the airframe. But the problem is that when the ground is taxied just now, it has reached horsepower! It has exceeded their known material strength limit! According to the current metal materials used in the aviation industry, the engine will be finished in a short time!

Unless, as Zhu Bin said, the so-called ultra-pure iron-chromium alloy is really that powerful! The working efficiency of the wing surface water cooling system inside is really so high!

Let’s not talk about this, the 3,000-horsepower engine is pushed to a speed of 800 kilometers per hour, plus four injection ports?

They were right. Zhu Bin, who was crazy, really drove the plane to supersonic speed in an instant! The propeller engine had no way to increase its speed again when it reached 880 kilometers. When he turned the power of the four superconducting magnetic fluid injectors to the maximum, a large amount of liquid methane poured into the combustion chamber, just like the terrifying eruption during a violent explosion. It produced violent force. In an instant, the plane was pushed forward like a rocket. Even Zhu Bin's cosmic infantry-level physique was squeezed tightly on the seat in an instant and unable to move.

The data brought by the sensors on the plane made the warning sound sharply, and a dazzling red light shone in the cabin. The pointer-type instrument panel went straight to the bottom. Only his holographic screen showed the data in just a few seconds, 1260 kilometers per hour!

"Whether this is a plane, it's just a rocket!" Zhu Bin laughed loudly, quickly reducing the power of the two engines, and the speed immediately dropped to a speed of 800 kilometers per hour, and rose to a height of 10,000 meters for a short uniform cruise. The groans of the fuselage and the flashing of the alarm lights slowly stopped.

"It's still not strong enough! If all parts are made according to the standards, they will definitely be able to achieve higher speeds!"

After all, most parts are made of three-dimensional printers, and the material accuracy and accuracy are incomparable to machine tool processing. However, in terms of strength, it is not as good as a 10,000-ton hydraulic press and die forging machine. This is still an aluminum alloy frame made by the Germans, otherwise it might have fallen apart just now!

In this state, Zhu Bin was already very satisfied. With this guy, there would be no problem when he went to the Eastern Pacific shipwreck point in the future, and time and concealment would be guaranteed.

Ten minutes later, the plane slowly landed on the runway. Wang Zhu and his group trotted over. Regardless of the propeller behind, they still emitted the heat of roasting people. They first helped Zhu Bin come out of the cockpit, then checked the body while it was hot, recorded various data, asked about the posture and feeling, etc.

Zhu Bin made a general sense and said frankly: "This aircraft is not suitable for air combat. It has insufficient maneuverability and flexibility. If the body material is made of ordinary aluminum alloy, it will easily disintegrate.

Therefore, it is still possible to be used as a high-altitude high-speed reconnaissance or horizontal bombing. It is indeed invincible in terms of speed, but it must not be as good as a mature jet fighter. This can only be used as an experimental reference and has no mass production value."

"That's it." Wang Zhu felt a little regretful, and then he let it go. As traditional aircraft designers, they care more about the guaranteed models with sufficient data support, such as the body of the propeller aircraft and the body of the jet aircraft that Zhu Bin showed them casually, all of which meet the standards of bionics and aerodynamics and are easier to accept. The guy in front of him is worried no matter how he looks at it.

However, Zhu Bin was able to run around and create a short-term supersonic speed, which at least means that this thing is useful.

After towing the plane back to the assembly workshop for further dismantling and inspection, Wang Zhu asked Zhu Bin: "What are you going to name this plane?"

Zhu Bin thought for a while and said, "It's so dark, just call it 'hidden arrows, secret arrows hurt people, hehe, I like it!"

What kind of bad taste is this? Wang Zhu shook his head, waved his pen on the thick summary information cover, wrote the word "secret arrow", and greeted several colleagues who had been tired for several days to go back to rest.

Zhu Bin squatted beside the plane and carefully planned that if the plane was filled with methane, it would fly at the most economical speed, at least a straight-line distance of 4,500 to 5,000 kilometers. This is still the most ideal weather condition. Then, when you reach the South Pacific, you need to have an intermediate buffer refueling platform.

But looking at the map, all the islands were occupied by the great powers, and it would be impossible to openly set up transit stations, but... he suddenly remembered the German Zeppelin.

A hard airship that is several hundred meters long can be suspended in the air for a long time, building a platform for a never-to-ground air fortress. If the shape is appropriately improved and the auxiliary engine is adjusted, it seems to be quite good as an air runway!

"Make this thing! It seems to be of great use!" Zhu Bin rubbed his chin and laughed.

A few days later, the German "Hebulou" company received an accelerated order from Zhu Bin. When he saw the drawings shipped over, Hugo Eckner, who was designated as the manufacturer, was surprised and shouted: "Oh my God! There are actually people who are crazier than me!"
