"This ......"

He Yongyan didn't know how to answer.

I have to admit that what Li Changfeng said is very reasonable and has convinced him.

But that's not something he can decide.

Gao Dali also wanted to persuade Li Changfeng, but he couldn't intervene on this occasion, so he could only look at Li Changfeng frantically and signal him not to risk his life.

But Li Changfeng ignored it.

In the end, everyone set their sights on Emperor Qianwu.

Emperor Qianwu pondered for a moment and asked, "Is it really okay?" ”

Li Changfeng smiled and said, "Father, do you think your son will risk his own life?" ”

Emperor Qianwu was also a decisive person, and when he heard Li Changfeng say this, he immediately made a decision.

"Okay, then it's up to you to test the flight."

After speaking, Li Changfeng walked towards the plane.

In terms of appearance, Li Changfeng's favorite aircraft in his previous life was the MiG series, as well as the B2 bomber full of science fiction, and the plane in front of him can only be described as ugly.

Of course, this is a propeller plane, which is not comparable to a jet aircraft in the first place.

Moreover, limited by technology, it would be nice for the first prototype to fly.

Li Changfeng first walked around the prototype plane to check the wings and landing gear.

He Yongyan explained on the side.

"The wings are designed according to the sketches drawn by Your Highness, as well as with reference to the wings of birds, the internal frame is made of the best steel, and the outer iron sheet is also good steel, but the surface treatment is not good, not smooth enough."

"There is no problem with the landing gear supporting the entire fuselage, but it cannot be retracted at present, what kind of hydraulic transmission structure did you say, Your Highness, has not yet been developed, mainly because the sealing requirements cannot be met."

"Theoretically, there is no problem with a load of six tons, but in fact it has not been verified, this test flight is empty, mainly to verify the handling of the aircraft, whether it can take off and land!"

“……”

Under He Yongyan's babbling explanation, Li Changfeng completed the inspection and found no potential safety hazards.

It's all primitive technology and doesn't have any electronic devices, which is easy to confirm.

"Okay, got it, good job."

Li Changfeng praised and climbed the ladder into the cockpit.

Emperor Qianwu hurriedly climbed the ladder and advised: "Be careful, pay attention to An An!" ”

Li Changfeng said with a smile: "Father, you can rest assured, there will be no problems." ”

Emperor Qianwu retreated, the ladder was pulled away, everyone retreated, and Li Changfeng started the plane.

Thundered!

The engine roared louder and louder, and the plane began to slowly accelerate.

The runway in front of him is about three kilometers long, which was built by Li Changfeng after He Yongyan began to develop the aircraft, and it is made of high-grade concrete, which is very strong and smooth.

Li Changfeng clenched the joystick tightly with both hands, and his mood was also a little excited.

In his previous life, he had been on a plane many times, but he had never been to the cockpit, let alone flown one.

In this life, I finally have such an opportunity!

Moreover, he was the first person in the world to fly an airplane.

With excitement, Li Changfeng stepped on the accelerator to the maximum, the propeller rotated faster and faster, and the plane sped up on the runway.

On the ground, everyone's nerves tensed.

Especially He Yongyan, who was even more trembling with excitement.

He followed Li Changfeng and worked in scientific research for more than ten years under the leadership of Liang Dafu, and almost all mechanical equipment has a lot of hard work.

He was thrilled after each study was completed.

But none of them can compare to this one.

In addition to the fact that he has invested too much time and energy, the most important thing is that if the plane can take off smoothly, then the dream of human beings to fly for thousands of years will truly come true.

Compared with the slow speed of the hot air balloon, subject to the weather, short endurance time, poor maneuverability and other shortcomings, the aircraft can be said to be a perfect existence, completely avoiding these shortcomings.

And its even more amazing load capacity is sure to change the world.

Theoretically, as long as the thrust of the engine is large enough, it can fly as much weight as it wants.

Emperor Qianwu was also very nervous, his fists clenched, and he asked, "Dean He, can you fly?" ”

He Yongyan said firmly: "This plane was designed by His Highness himself, I am just completing his design, I believe that Your Highness will definitely be able to fly!" ”

The light in Li Jianye's eyes was almost about to become substance, staring at the plane and muttering, "You must fly!" Be sure to fly! If an airplane is made, what is a hot air balloon? This prince wants to build a real air force that can fly to the whole world! ”

Feng Quji's cloudy old eyes were shining, staring at the plane, his withered yellow face full of old age spots became ruddy at this time, and his hand on crutches trembled slightly.

Ye Qingcang helped Feng Quji, the muscles on his face were tense, and his eyes widened, for fear of missing any details.

Under everyone's gaze, the speed of the plane reached the critical value of takeoff, and the tires on the landing gear left the ground from time to time, and Li Changfeng clearly felt that the plane was jolting one by one.

He knew it was time to take off.

Take a deep breath, grasp the joystick tightly with both hands, and slowly pull it inward.

The plane suddenly tilted its head, and the scenery on both sides began to descend rapidly.

Li Changfeng until, the plane took off smoothly.

Suddenly, a burst of cheers erupted from the test flight site.

"Fly! Fly! It's really flying! ”

He Yongyan pulled the staff behind him to dance clumsily, like a child, and even tears flowed down with excitement.

Emperor Qianwu also looked excited, and muttered to himself: "It's flying!" It really flew! This will be a historic moment, destined to go down in history, and people's dream of flying has truly been plugged into the wings of take-off! ”

Li Jianye shouted excitedly: "This prince wants to build a great air force!" A real Air Force! Whoever dares to be disrespectful to me, this prince will fly a plane to blow up his mother! ”

At this time, no one cared about his vulgar language, Feng Quji and Ye Qing were in tears, staring at the plane that was already soaring in the air.

"What a blessing to be born in this world!"

"The old man just wants to take this plane once before he dies and overlook the great rivers and mountains from a high altitude!"

Gao Dali looked at the plane tremblingly, and his heart was in his throat.

Theoretically speaking, with Li Changfeng's strength, even if something unexpected happens, it will be fine.

But that's theoretical, after all.

Yu Gong, if something happened, he knew that Emperor Qianwu would definitely not be able to withstand such a blow, and it would undoubtedly be a huge loss for Da Qian.

Yu privately, he likes Li Changfeng very much and doesn't want Li Changfeng to have anything to do.

Whatever you want.

Just when everyone was cheering, I saw the plane suddenly raise its head, and then suddenly lost control and fell straight to the ground.

Emperor Qianwu's face instantly turned pale as paper.

"Long Wind!"

Emperor Qianwu screamed in surprise and ran over in a panic.
