Chapter 253: Ke Han picked up the receiver frame and held it in his hand and weighed it. He thought it was interesting, so he looked carefully and saw that the middle of the receiver frame was covered with two pieces of iron, and the two ends of the bracket held the receiver.
The headphones are stuck so they can be placed on the phone case
"At present, the receiver is replaced by headphones, so there are two headphones on one phone. Yes, one is used to answer and the other is used to pass messages." Ding Yan still explained the reason why there is no receiver.
Ke Han said "um" and said that he was listening to his story carefully and had figured out the meaning. Then he smiled and looked at Ding Huan sincerely with consulting eyes.
Ding Wei nodded and signaled that he could try the effect. Ke Han took off his headphones and called out to the headphones. Then, he heard a "sweet" electric current sound.
Ke Han frowned, which reminded him of when he was a child, in the countryside of his grandmother's house, at the rural members' meeting, the old secretary liked to pat the microphone, and then got closer and blew "huh" into the microphone, which was from the big horn.
The deafening "dongdong" sound and the harsh electric current sound came from inside, which made people feel irritated. At this time, the old secretary would smile, expressing a sense of satisfaction and pride in control of power, even though he was also
Knowing that doing this is very annoying, but this is a symbol of his right to express his only ability to scold others in the microphone.
Ke Han smiled at the receiver apologetically. To be precise, it should be called the headphones. He smiled at the headphones, and then said to the person on the other end of the phone: "Oh, sorry, this is not the result I want!"
After hearing Ke Han's words, Ding Yan was a little surprised. He thought his design was not satisfactory enough, so he stayed aside in panic, waiting for Ke Han's interpretation.
"Hey, hello! Is anyone?" Ke Han shouted in the headphones, "I am Shi Ziheng. Anyone who heard it, please reply!"
"Oh, hello, Mr. Shi!" A familiar response came from the headphones. The sound was actually from Master Huairou. His hearty laughter was mixed with the slogans of the team's training, and Dongfang Xiao's
Instruction
"Where is this? Master, have you arrived?" Ke Han asked in surprise and suspicion.
"Haha, this is the highest command center!" Master Huairou laughed teasingly, "Just in my dormitory, do you still remember the place you stayed last time? That's it! How about it? Mr. Shi, Ding Yan and their achievements
Are you still satisfied? It was absolutely shocking to create these things in just a few days!"
Ke Han smiled with satisfaction and replied, "Who said no? Don't forget, I discovered them all, that's a super baby, you give up your fairyland to work for my people, and be enlightened
It's still quite high! Even if I owe you a favor..."
"Forget this, the family you said without saying two families, why did you break your promise by yourself? Haha, that, as long as you still remember the super big tripod you gave me, I'm waiting to use it!
"Daoist Huairou smiled and said cheerfully, "Let's talk later when we meet, oh, by the way! The directional device improved by Master Agui is used on hot air balloons. I don't know what to do? When will I try it
Try it? I tell you that hot air balloons are a good thing. In our complex terrain, it is perfect for you!”
"Oh?" Ke Han was surprised. He visited Ding Yan to discuss his research and development issues, and then neglected Master Agui. He turned around and glanced at Master Agui apologetically, and looked at him with soft heart on the other end of the phone.
The Taoist priest said, "Think about it, you must seize the time to try it over!"
After talking on the phone, Ke Han turned around and smiled with satisfaction, and asked Ding Yan: "You can contact these two places for the time being, right? In the future, can you have more places to call at the same time? I mean, if you need it,
If so, are your existing headphones enough to assemble such a phone?"
"Not enough!" Ding Yan replied affirmatively, and then said, "However, I can try to design some of my own, but it takes time."
"Of course!" Ke Han breathed a sigh of relief and turned to Master Agui, "I know everything. You have a weapon, Master Agui! Take advantage of this skill to try it together?"
Agui was a little embarrassed. After a long time, he finally said something, but for a moment he didn't know what to say, so he just nodded silently, and then walked straight out of the cave.
"Actually, it's really cool to have a hot air balloon flying around in the sky! This is something we dare not even think about. We can see it on the boss's side. Of course, the substantive problem is a matter of course.
Yes, this credit should be attributed to Master Huairou, which can be seen that the airbag seems to have been treated with gum, probably Eucommia ulmoides or konjac galvanis? As for where he got the mysterious fuel, I don't know, well
, It's really shocking to create such a great impact! After all, the master is a master, otherwise he wouldn't have refined a magic pill. So, first of all, he solved the fuel problem required by the heat, so we can
The next improvement issues, boss, you know, it seems that what I said is redundant?" Master Agui modestly introduced Ke Han about the problem that the impossible becomes possible
Ke Han really knows something about hot air balloons
The first manned hot air balloon designed by my country was researched and designed by a mechanical factory in Xiangfan City, Hubei Province in 1985. According to Xinhua News Agency, the balloon has a volume of 2,450 cubic meters, spheres, hanging baskets and The heating system weighs 200 kilograms in total, with a maximum effective load capacity of 400 kilograms. It can ride a six-person hot air balloon at the same time, use petroleum liquefied gas as fuel, and the maximum rise speed is three meters per second, and can fly freely or stay in the air.
The news reports at that time also introduced the main uses of hot air balloons. It was reported that hot air balloons can be widely used in aviation sports, aerial tours, aerial advertising, aerial photography, sea patrols, parachuting training, meteorological detection, air pollution monitoring and high altitudes.
Wait for
Ke Han never expected that in the era when he had traveled through time, an old Taoist priest had developed a hot air balloon that could carry three adults long ago. Ke Han couldn't help but admire him!
"Your weapon lies in freely controlling the most difficult direction problem for hot air balloons, right?" Ke Han was still a little worried. After all, this direction problem that was difficult to control in modern times, where advanced technology was later popular, was a little bit of mechanical knowledge.
The old antiques of technology were easily solved? It was really incredible, so I asked Agui directly, which was the question he cared about the most
"Although hot air balloons are also called aircraft, they cannot fly freely in their own direction, so we can only control the height of the balloon to change the direction. Why? Because if in windless weather, the balloon can only float up and down, and there is no direction.
Word
But the atmosphere is moving all the time. In weather where people can clearly feel windy, the wind speed and direction of high and low altitude will be different.
At a height not far from the ground, affected by terrain, buildings, etc., the wind direction will change and the wind speed will decrease significantly. In weather that we generally believe that there is no wind, local air vertical convection will also affect the proximity
Air movement in different directions on the ground surface
Often in the morning or evening, from the ground to the air, there may be obvious wind direction changes every few meters or ten meters, and some even the opposite wind directions are the same.
The instrument I am studying is actually measured based on the phenomenon of the atmosphere and changes the flight direction of the balloon. Therefore, my weapon should be called a wind direction measuring instrument. Its characteristic is that it is connected to adjust the fuel.
The size of the combustion flame can quickly change the height of the hot air balloon and adjust the running direction of the hot air balloon.
Specifically, we experience different directions of each height layer through the relative movement of the balloon and the ground in the air, and then manipulate the balloon to lift or lower it to the height of the wind direction we need, and keep flying at this level, so that we can
Achieve your goal of flying to a goal
In this way, the balloon can not only be lifted and lowered, but also change directions in the air and fly in a specific direction.
Of course, this requires the speed and direction of the wind
It can also be simply said that the balloon will fly wherever the wind blows, because as far as the hot air balloon itself is concerned, it does not have its own power system, and can only follow the wind as fast as the wind speed and the balloon can fly as fast as the speed.
!”
——Master Agui explained so much seriously and in detail, and finally, he said cautiously——"As for the effect, it still needs to be tested"
"So that's the case? But it's really complicated!" Ke Han sighed with some insight, and then waved his hand happily and invited Agui and Ding Yan, "What are you waiting for? Let's go! Let's go here
Just try it”
The three of them got out of the cave and quickly walked to the small square in front of Master Huairou's dormitory. But seeing that Huairou had already sorted out his hot air balloon, they waited for Ke Han and the others to come and test it.
Huairou saw Ke Han, of course there was a lot of greetings. Although he had just passed the phone and returned to the Xinu border camp, the etiquette was the same.
Shao Chong took some fuel, and soon the airbag was filled with hot air, opened and became bulging. Ke Han, Ding Suang and Master Agui stepped into the bamboo basket one after another, and waited for Agui to connect his wind direction to measure.
As expected, he connected a tube like a catheter to the homemade gas firepower regulating valve
Ke Han looked carefully and secretly admired Agui's intelligence and sighed in his heart: This regulating valve is no worse than the valve on the liquefied gas stove in our house!
"This tube was also given to Ding Yan by the foreigner. Ding Yan has not been used, so I brought it first, but unfortunately there was only one, and it was a little shorter!" Master Agui rushed to Ding, who was much younger than him.
Smile and smiled, she looked so cute, as if she was shy because she had taken someone else's stuff in vain
"I said why is there half a pipe missing? Master Agui, in fact, there are still many in my wooden box, a total of ten. I was packing that day, and I planned to cut a few and put them naked on the cave rocks.
The phone line, I still couldn't bear to use it later. Unexpectedly, you cut it a lot. Oh, I'm so embarrassed to say it's short?" Ding Yan widened his eyes and said in surprise, and then he laughed at Ke
Han said, "If he has rewards, he will have to intercept half of it!"
Master Agui quickly connected his wind direction measuring instrument and fire power adjuster, and in an instant, he flew up.
Dongfang Xiao, the governor of the city guarding the city, led his subordinates, stood in the empty small square, and stared at Ke Han and the others curiously, watching the hot flame "huhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
Blowing the airbag, leading the three people to the sky, suddenly, envious
"A magical artifact! It's extremely magical!" Ouyang Zhendong and his Xinu brothers were all shocked and sighed!
The indigenous savages were also stunned. They came over and approached the Secretary-General of Wang Sanjie, whom they trusted the most, and asked this and that with a gusto, his face full of admiration, and at the same time, he seemed to be their genius king.
