Looking at the crude airplane in the sky, Zhu Jingyuan let out a sigh of relief, and sure enough, it took off immediately.

Because the wing shape of early aircraft was incorrect, the lift they obtained was very limited, so the wings could only be enlarged as much as possible.

Zhu Jingyuan directly gave the correct wing shape, and modified it from the existing wing size, so the lift was very abundant.

In addition, the engine is relatively powerful and the control structure is relatively reasonable.

Therefore, for the first flight test in the world, it was able to fly stably.

At least it has achieved the effect of the third test machine of the Lite brothers, and it will actually be even better if we simply calculate the hard parameters.

The aircraft invention patent has basically been obtained.

These officials from the Ministry of Industry should be embarrassed and have no guts to plagiarize the ideas of their own imperial grandson.

Zhu Jingyuan was slightly excited for a few seconds, then looked at the plane getting higher and higher, and began to feel a little worried.

A successful test is originally a comedy. Don't let it turn into a tragedy just because everyone is too excited.

So Zhu Jingyuan patted Li Rui, who was in a daze:

"Be careful, use the loudspeaker and shout quickly, don't let him fly too high!"

Li Rui was in a trance, but he was more excited and excited. When he heard Zhu Jingyuan's cry, he woke up slightly and asked subconsciously:

"Why?"

Zhu Jingyuan explained:

"After all, this is the first test. If the operator fails to control it, the person who falls down may be killed. Let's test it at a low altitude first to familiarize ourselves with the aircraft control."

Li Rui understood immediately and immediately raised his horn and shouted to the sky, asking the world's first pilot to fly carefully and not to continue to rise.

Zhu Jingyuan was still nearby reminding:

"Don't be too anxious to land, just float slowly and try to adjust the direction slightly to adapt to the control method..."

Li Rui nodded and continued to shout reminders.

In fact, both of them were a little too cautious.

Early aircraft were slow enough, much slower than later generations of cars. The first military aircraft had a speed of only 60 kilometers per hour.

With a total engine power of more than 30 horsepower, how fast does it want to fly?

At the same time, the wings are huge and regular in shape. It is a standard hang glider. As long as it does not encounter a sudden large whirlwind, there will be no problems.

The craftsman responsible for operating the aircraft has also flown hundreds or thousands of hang gliders. Although he is very excited now, his body instinctively knows what to do.

Coupled with the reminders from Zhu Jingyuan and Li Rui, there were no major problems during the flight.

The aircraft slowly lowered its altitude, stabilized at about three stories high, and slowly circled several large circles over the test site.

Then at Li Rui's request, he began to lower the altitude carefully, and according to Zhu Jingyuan's reminder, he landed slowly at one end of the runway.

The plane swayed a bit as it approached the ground, but eventually it landed normally and slid along the runway for dozens of meters before stopping.

The craftsmen who had been watching for a long time immediately swarmed up and surrounded the plane that had just landed.

The pilot who was testing the plane was obviously very excited. He squatted in the middle of the plane for a while before standing up. He was still swaying on the way down.

The two assistants on the anti-roll handlebar saw this situation and immediately ran over to support the pilot.

The pilot was held up by his companions. After he stood firm, he finally couldn't hold back his emotions. He suddenly raised his hands and shouted:

"We made it!"

When this voice was shouted out, the surrounding crowd, which had just become quiet, immediately became noisy again, and it lasted for a long time before it subsided slightly.

Finally, Li Rui brought the test pilot and two anti-rocker assistants to Zhu Jingyuan.

As the host of the test, Li Rui still reported with a bit of excitement, a complex and excited expression:

"Your Highness, the fixed-wing flying machine has been successfully tested. The flight time exceeds twenty minutes, the flight height exceeds ten meters, and it can hover stably at about ten meters."

"Thank you, Mr. Li, and all the craftsmen for your cooperation."

Zhu Jingyuan took a deep breath and expressed his gratitude solemnly, while not forgetting to remind himself:

"Now that the experiment is successful, I would like to ask Director Li and everyone to sign, and we will apply for the aircraft patent!"

Li Rui didn't think about the patent, but he immediately realized that this patent could indeed be applied for, and it was indeed important enough, so he immediately agreed with all his strength:

"No problem, I will prepare the confirmation documents right now. All the craftsmen on site are certifiers. You are the inventor of the aircraft!"

Zhu Jingyuan nodded solemnly:

"Sorry to trouble you all."

Just as Li Rui was about to leave, Zhu Jianyan next to Zhu Jingyuan seemed to finally react and reminded him quickly:

"Remember to inform Zou Shangshu...I also need to tell His Majesty that I will make a phone call. There should be a phone here, right?"

Some of the superiors, Li Rui, reacted again and quickly expressed their gratitude to Zhu Jianyan:

"Thank you, Your Highness, for reminding me that there is a telephone number at the testing site. Please follow me."

Both of them knew that at this time, Zou Shangshu and the emperor should have started eating, but the success of the plane was definitely worth disturbing their meal.

Zou Shangshu is indeed eating.

In the morning, Zhu Jianyan and Zhu Jingyuan and his son left together. Master Zou finally breathed a sigh of relief and immediately returned to the office to continue his work.

I answered more than 30 phone calls and signed dozens of documents all morning, but the work still has no end in sight.

During lunch time, Zou Shangshu did not leave the office at all. He had a lunch box delivered to him and continued to read documents while eating.

When Li Rui's call was transferred by the operator, Zou Shangshu reluctantly put down Kuaizi.

"Why is there still someone working at this time?"

Zou Shangshu muttered something, wiped his mouth with a tissue, and picked up the microphone on the table.

Li Rui's excited voice immediately came out.

"Da Sikong, I am Li Rui. This is the outdoor testing ground in the west of the city. His Highness Jingyuan's fixed-wing aircraft has been successfully tested!"

"What?"

Zou Shangshu was obviously stunned for a moment, and he did not immediately realize what Li Rui meant.

Li Rui repeated his report again and briefly explained the situation of the flight test.

Zou Shangshu finally stopped coming at all, and then suddenly stood up, and the kuaizi in his hand fell directly to the ground:

"Succeeded? Really succeeded? How is this possible? You are not lying to me, are you? Do you have any photos?"

Li Rui was also stunned when asked:

"I didn't take any photos. Everyone was so excited at the time that I forgot to take photos. But I can fly again at any time. I'll just take photos when I fly again."

Zou Shangshu finally reluctantly accepted the reality and slowly sat back with the microphone in both hands:

"I...I'll be there in a moment. You can ask the craftsmen to continue checking and prepare for testing again. We will continue testing in the afternoon."

Zou Shangshu hung up the phone and didn't eat the rest of the meal. He took the phone and continued dialing, asking for the phone number of the General Affairs Department, preparing to contact the emperor.

As a result, the General Affairs Department responded that the emperor was on the phone and asked Zou Shangshu to wait for a while.

Zou Shangshu was stunned for a moment, and soon understood that it was Zhu Jianyan and his son who had reported directly to the emperor.

However, Zhu Jianyan and his son's report was their business, and they still had to fulfill their responsibilities and report through their own channels.

Zou Bingtai waited patiently for a few minutes. The Secretary of General Affairs called directly and then connected to the emperor.

After a brief greeting, Zou Bingtai directly explained the situation. The official below reported that the aircraft had been successfully tested and he was going to go and verify it himself.

As expected, the old emperor Zhu Zhongliang smiled very happily and said:

"I already know. Jian Yan just told me that I am about to go there. Let's go together. I will ask the driver to pick you up."

"Thank you, Your Majesty..."

Zou Bingtai agreed subconsciously, feeling helpless in his heart.

Being able to ride in the car with the emperor is certainly a symbol of trust.

But the old emperor is different from other old people. He likes to take a car wherever he goes. I wonder if he is promoting the Royal Automobile Factory.

The young ministers are fine and think it's quite fresh and fashionable, but the old people are a little uncomfortable with it and can't just shirk it.
