For Leng Feng's research, Li Shimin always hesitates to speculate.

With gunpowder in front, even if Leng Feng researched something more powerful, he was mentally prepared.

Lao Liu Tou also sat down, and greeted all the princes and princes with a smile.

After drinking a glass of wine, Leng Feng shrugged: "I wanted to get a plane to try out when I was bored, who would have thought that the old guy who was losing Hui thought it was something important, and actually called the people who undertook it." ”

"Airplanes?"

Seeing that Li Shimin was puzzled, Leng Feng could only roughly explain to him what the plane was.

After listening, Li Shimin clenched his fists: "Gong Yihui is not wrong, and Cheng Qian is not wrong." Hot air balloons are already a militaristic powerhouse, not to mention more agile planes than hot air balloons. All you see is its role as a means of transportation, and in my opinion, as long as this thing is equipped with gunpowder weapons, it is an almost invincible existence. ”

Talking to a military emperor about this plane is the result. As long as people's minds turn around, they know how to turn an airplane into a bomber.

Fang Xuanling was curious about what the Emperor and the Protector were talking about, so he came over to inquire, and Li Shimin stuffed the chicken leg without hesitation: "Eat, why are you asking about these." ”

A wedding feast in which the guests return with a full stomach.

Fang Xuanling and the others returned to the Academy of Literature, and Li Shimin stopped fishing, and followed Leng Feng into Li Tai's laboratory.

The production speed of the public loser is very fast, and with the concerted efforts of more than 100 people, the rough framework has been made.

Patting the shell of the plane, Li Shimin asked, "Can it really fly?" ”

Leng Feng nodded: "Yes, as long as you carry a steam engine, you can still fly at a lower level." However, in principle, it makes sense, but the actual situation is not necessarily the case. You've also seen the green sparrow's generator, and failure is almost common. ”

Two days later, Li Tai was busy with mundane things, and he was very curious to see so many people in the laboratory.

When he knew what Master was going to do, he simply sealed the generator project temporarily, and had to tinker with Master about the plane.

With Li Tai's experimental team joining, the internal structure of the aircraft was quickly drawn. Having experience in the study of steam engines, they are very familiar with the various connection devices, and they make use of each of them as much as possible.

In a month, the most primitive aircraft was made.

Looking at the results in front of him, Li Shimin rubbed his hands excitedly.

Unlike a hot air balloon, the plane can independently decide the direction of flight, which is really exciting.

Seeing that his father had the urge to try, Li Tai hurriedly stopped: "Father, it won't work, this thing is too dangerous, the first result is almost certain to fail, to put it mildly, if you get hurt or what, the imperial brother will definitely peel my skin." ”、

Looking at the plane in front of him, Leng Feng was also very worried. The experiment of the airplane is too dangerous, and if you don't get it right, you will die. Especially the one in front of me, which is made according to the theory, must have more than one fault.

When he was in a dilemma, those guys with gloomy faces came over, and after saluting the three of them, they took the lead and said: "Wu Dayuan, who is lowly and has been sent by His Majesty, since he wants to experiment, he is the best candidate." What's more, although the lowly martial arts are vulgar, it is still difficult to say that they fell to death. The emperor is too high, and he is invited to go up for experiments. ”

Li Shimin said solemnly: "I appreciate a warrior like you, since you recommend yourself, then the opportunity will be given to you." If something happens to you, I will ensure that your family will be happy and prosperous for five generations! ”

Although Li Shimin has abdicated, no one doubts the weight of the words of a supreme emperor.

Parachute, bring on, armor, put on, when all the protection was ready and the operation method was familiar, Wu Dayuan laughed and got on the plane.

The test flight was held in the wasteland where the lightning company was originally addressed, and there was no one in a radius of dozens of miles, which was the safest.

The steam engine, which uses gasoline as the ignition source, is activated, and the linkage drives the propellers in the nose to rotate, and the wheels at the bottom also have a tendency to move.

At first, the propellers were spinning slowly, and the wheels were only symbolically turning. When the power reached a certain level, the plane got rid of its shackles and began to move forward, faintly showing signs of flying.

In the vast field, only Wu Dayuan and the plane were spinning around.

Looking at the plane still on the ground through the telescope, Li Shimin worried: "It won't be impossible to fly." ”

Leng Feng shook his head uncertainly, the principle is fine, but reality is always used to giving people a heavy blow.

"Off the ground! Out of the ground!! ”

Lee Tae, whose eyes had never left the binoculars, jumped on the spot.

Li Shimin hurriedly took the telescope to look at it, and saw that the wheels of the plane had clearly left the ground, and there was a tendency to fly higher and higher.

It's just that after the plane is a few meters high, it can't be any higher, and can only go up and down in a curve.

Leng Feng breathed a sigh of relief: "It seems that there is still a problem, but it is flying anyway." ”

Li Tai is still jumping: "It's good to fly, and if you fly, it's a success." ”

However, the good mood is destined to not last forever, when the plane rose and fell again, it did not get up again, but poked straight to the ground, and the wings and other parts were suddenly broken.

"Go and save someone!"

Leng Feng put down the binoculars and anxiously got on a horse.

A few meters high, Wu Dayuan couldn't fall to death, and at most he was seriously injured. But there was a gasoline canister in the nose, and although it didn't contain much, it could still kill the driver when ignited.

Fortunately, the craftsmanship of Datang's craftsmen is very trustworthy, and the gasoline canisters have not been leaked. Although Wu Dayuan's nose was blue and his face was swollen, there was no further injury.

Looking at the plane that was ignited by the flames, Wu Dayuan was heartbroken and wailed to go up to put out the fire.

"Be quiet, burn it, burn it, and people will be fine. Let's go back and make another one in a while. ”

After listening to Leng Feng's reprimand, Wu Dayuan quieted down.

Several other members of the secret guard carried gasoline canisters with them, and after making sure that the plane could not be saved, they simply set all the parts on fire.

Secrecy!

After Li Chengqian knew what his master and father were doing, he gave him great support.

Good wood is constantly being sent, and in order to confuse the public, a lot of things that I don't know what to call are also sent.

I don't know why they are so afraid of leaking, even if someone steals the drawings, if there is no suitable craftsman, isn't it for nothing? What's more, the steam engine and the internal devices were all tinkered with by Li Taihe's subordinates, and there were no drawings.

After analyzing the reasons for the fall of the first plane, this time the wood was chosen for the production, which was both light and tough. The internal equipment has also been improved by Li Tai.

The driver is still Wu Dayuan, and the place of the experiment is still the field.

This time, Wu Dayuan was broken and almost burped....
