"Look, look, little white and white!" Qi Linlin grabbed Wu Pan's arm with both hands and shouted excitedly.

Although Sun Yan next to her was not so excited, the expression on her face was obviously full of joy.

Wu Pan and Shen Mo glanced at each other helplessly, and also looked up at the sky, where a cute white flying machine seemed to be slowly and quickly crossing the sky and disappearing behind the building.

This thing is also what they are here for.

Different from what Shen Mo Sun Yan saw at school, these "air buses" have two rows of four seats inside, and the fuselage is naturally much wider than the little Pegasus that Atletico was riding at that time, plus as a low-speed aircraft, it does not need a pointed and long needle body, and can be made more wide and sleek, so these Pegasus intelligent aircraft are all round white fat people. The white egg-shaped cabin is topped with four large white circles placed horizontally, and the inside is a propeller, which looks quite simple and cute, and it is very cute at first glance.

In fact, these guys gained countless female fans as soon as they appeared, and they received the nickname "Xiaobai" It is said that the original version of the nickname was "Xiaobaihua", because it looked like a four-petaled small white flower from above, but the information drifted in the process of transmission, and the result became the current name. As for the original name of Pegasus unmanned intelligent aerial vehicle, no one has mentioned it, and even the small Pegasus that is one size smaller has been given a "little white" name by everyone's love house and Wudi, although the latter is not mellow enough to be much worse in cuteness.

Speaking of which, Shen Mo and the others have to thank these local specialties for their cute things, it is with the help of these cute and soft fat people that he and Wu Pan were able to successfully convince their respective girlfriends and let them achieve the achievement of "bringing their girlfriends home". When the "Big Yellow Duck" was exhibited around the world, many people made a special trip to visit and take a group photo, and now they have the opportunity to get close to Xiaobai, and they can sit in it and fly into the sky, naturally no one can refuse.

And now it's time for the two of them to make good on their promise.

The "Sky City" experimental system built by bees on the roof of their bee garden uses hundreds of Pegasus intelligent aerial vehicles to form the world's first rooftop bus system. These white fat people who fly around in the sky every day have long become a hot topic in the city, and there are many fans and followers across the country and even around the world.

However, it is a pity that in the past, this system had to be tested while being built, and only the staff could go up, and ordinary people could only watch from afar. Later, with the gradual improvement of the system, more people began to have the privilege of sitting in it, not only the management of the bees could take them to and from work, but even ordinary employees could occasionally enjoy the fun of flying to work if they could make an appointment in advance.

There is naturally no shortage of "superior dogs" and "selfie dogs" in this gang of people, and more and more photos and videos of sitting in "Xiaobai" overlooking the city and buildings began to appear on the Internet.

In fact, whether it is taking the cableway gondola, or taking the Ferris wheel gondola, in fact, we do not lack this opportunity to overlook all beings from the sky, but the psychological feeling is different after all, although the people who sit in the "Xiaobai" are only passengers, can only fly on a fixed route, and there is not much freedom and pleasure in flying the plane into the blue sky, but it is better than sitting in the gondola with a more rigid route, especially the psychological feeling is much worse.

Then before Shen Mo and their summer vacation, Bee brought everyone good news, saying that after long-term safety testing, their "Sky City No. 1 Network" has finally obtained the trial operation permission of the relevant departments, and some tourists can be accepted to experience this new product, which is why Wu Pan and they came today.

In fact, the four of them are not without the experience of intimate contact with intelligent aerial vehicles, Shen Mo Sun Yan has seen the "Xiaoxiaobai" ridden by Atletico Madrid, Wu Pan and his girlfriend Qi Linlin have already come to the bee garden to see "Xiaobai", and they are fortunate to sit in it and take a group photo, but at that time the machines have been locked, and they can only see but not fly.

Although it is a "rooftop bus network", it is not without "stations" on the ground.

Not long after entering the bee garden, the four of them followed the prompts on the map on their mobile phones and quickly found a fenced flying station, which was actually a clearing on the square with a landing symbol for positioning, and a shed next to it as a waiting area or waiting area.

According to the instructions that suddenly appeared on the mobile phone, they need to weigh and sign up first, and then they need to sit on the bench in the waiting area next to them for a while, and if the system has a vacant seat, they will be sent a ticket to buy a ticket before they can buy a ticket to board.

Then the two pairs of students and couples were depressed, and it was basically impossible for them to get on the same plane.

And the fact is also the same, the two girls and the other two girls with similar sizes boarded the plane and flew away together, leaving only Shen Mo and Wu Pan, the two good friends, sitting next to each other, watching the cute flying machines fly over and slowly descend in four large circles, and then fly away again after a while, slowly disappearing out of the sight of the two.

However, it gave them enough time to observe the white fat men more closely.

For example, the landing symbol on the ground is not directly drawn on the floor tiles of the square, but on the ground of the square is laid with several take-off and landing platforms the size of double beds, with two parallel shallow grooves in the middle, and when Pegasus lands, the two skids will slide to the bottom of the shallow groove under the action of gravity, one to fix the aircraft, and then you can use the metal contacts at the bottom of the groove to charge it.

This is also the biggest difference between Pegasus, which uses a traditional lithium-ion battery pack for power, while the former uses supercapacitors.

A supercapacitor is a kind of capacitor like a battery, which has the advantages of short charge and discharge time and greater power output, and was once considered a strong competitor for the future super battery. However, the energy density of the supercapacitors actually produced, i.e., the wattage of usable energy per kilogram of weight, is hardly comparable to that of lithium-ion batteries, as well as the fuel cells under study. However, as a fixed-point bus system, supercapacitors are the best choice for Pegasus, because the former can complete the charging operation in tens of seconds, while the charging speed of lithium-ion batteries is measured in hours.

The energy density is significantly smaller than that of aviation fuel, which has been an obstacle that has limited the electric motor from becoming the mainstream of aero engines.

During the Cold War, in addition to studying ultra-long-endurance ships such as nuclear-powered submarines and nuclear-powered aircraft carriers, the United States and the Soviet Union also had plans to put reactors on airplanes and build ultra-long-endurance nuclear-powered aircraft, but the plans were eventually shelved due to radiation protection issues and possible nuclear contamination from plane crashes.

So, to this day, with the exception of a few experimental solar-powered aircraft, the vast majority of electric aircraft still only use batteries as an energy source. And the battery has a very cheating attribute, that is, the weight is still there after the power is discharged, resulting in the same weight during the whole flight, and the more natural the battery capacity means more weight and smaller usable load capacity, in order to reduce the weight of the battery, Pony naturally thought of a small amount of fast charging solutions.

This is precisely the strength of supercapacitors, and in the tens of seconds that passengers enter the aircraft and are busy fastening their seat belts, the machine they sit on has heard that the two legs have gained enough energy to fly for a while.

Of course, these materials are sent to their mobile phones, one is to let everyone pass the waiting time, and the other is also popularized, but the bee obviously hid a hand, and did not disclose the specific battery life honey. Wu Pan's observation should not be long, because he saw that not every Pegasus that landed would open the door and drop off passengers, they obviously came down to recharge.

"Xiao Mo!" Wu Pan stabbed Shen Mo, "Have you noticed that these Xiaobai are actually very similar to tadpoles, they should actually be called 'flying tadpoles', flying tadpoles!"

"What about the tadpole's tail? the tadpole only has two legs?" Shen Mo said, pointing to the two legs of the pegasus that had just stopped not far away, which were two fixed skids.

"How come tadpoles don't have two legs? Tadpoles grow their hind legs first and then their front legs, so naturally there are tadpoles with two legs. ”

"Well, there are not only two-legged tadpoles, but also mutated tadpoles with two legs that have been exposed to nuclear radiation and have deformed front and back legs on the same side!"

Wu Pan also understood that his statement was a little far-fetched, so he had to explain: "I mean that their streamlined shape is very similar to tadpole heads, and the fat ones are a little flat, just understand the general meaning, don't pick out the details." ”

"Roughly speaking, the designer of the bee maliciously sells cuteness, and deliberately makes it look so soft and cute to cheat money!" Shen Mo said as he shook the little white plush toy in his hand.

Large and small Pegasus are sought after, of course, bees can't let go of the business opportunities, and soon launched their own model toys, and the variety is very rich, from small keyhole mobile phone stickers to small drones that can fly into the sky simulation scale models, everything, and even more popular plush toys for girls, Shen Mo and Wu Pan held the white fat man in their hands That's how they came.

The waiting time was not too long, and soon the two of them were notified by the system that they could buy tickets, and the two of them looked at each other's mobile phone fares, Shen Mo 63 yuan, Wu Pan 72 yuan, the two brothers should be separated for a while.

"Hehe, it's really selling tickets by the pound!" Shen Mo sneered.

Although he knew that the purpose of weighing and matching passengers was to facilitate the balancing, the bee's practice of selling tickets by the pound still made him feel full of slots.

All aircraft, from civil aircraft and large transport aircraft to mosquitoes and fruit flies, need to be trimmed to make the flight attitude more stable.

Some passengers who have flown on small and medium-sized aircraft may have encountered a "human matching" in which a flight attendant manually assigns a seat after boarding. Large aircraft generally use software to balance, after everyone buys a ticket, before receiving the boarding pass by the computer automatically completes the balancing, the program will automatically change the boarding pass and plan to board the passengers and their luggage scattered arrangement, to avoid excessive piling up caused by the trim is destroyed, so as to achieve the purpose of safety and fuel saving.

Of course, because large aircraft seats have more and greater weight, many airlines now begin to allow passengers to choose their preferred seat position, but only passengers who buy tickets first can choose, and sometimes they will charge additional seat selection fees, as for later passengers, they will still be arranged by the system "see the seams" of the seat number. Of course, this trim is actually more relaxed, after all, the airline does not have everyone's weight data.

So far, Samoa Airways seems to be the only regional airline that requires passengers to provide weight data at the time of ticket purchase and has to be checked before boarding.

Samoa has one of the highest rates of obese people in the world, with a global obesity rate of more than 80% among Samoans aged 15 and above, ranking sixth in the world, according to the World Health Organization. The world's "fattest" is Nauru, also an island nation in the South Pacific, which quickly became famous among wealthy countries after selling off the phosphate rock formed from guano fossils, and is now known for its high obesity and unemployment rates.

In fact, large airlines in other countries have also had cases of letting fat people buy two tickets, but because of suspected discrimination and breach of contract, most of them have failed, and only Samoa Airlines, which has suffered from "fat damage", can not bear it anymore and is the first to engage in "ticket sales". To be sure, with the rise of low-cost airlines, there will certainly be more and more similar situations.

Of course, the main purpose of bee weighing and boarding is to facilitate the trim, and the Pegasus, which has only four seats, obviously does not have much margin, so they use a simple and crude trim method, that is, let the four passengers with close weight go up together, so that it is naturally easy to maintain the trim state. The queuing system at the rooftop station automatically groups the queuing users according to their weight, and sends them ticket purchase permits when there are enough four people, and the next Pegasus is theirs after all payments are made, otherwise they have to wait.

It is conceivable that those who "do not have a standard weight" are unlucky, and the thin people and children are better, they only need to wait a little longer, and it would be good to get together four thin people to board the plane together, but the fat people will be in the cup and will be directly denied boarding. Although Pegasus has more payload than the little Pegasus, it still can't hold the four fat men, even if the price increases.

Speaking of prices, the "Sky City" that targets the air bus system should definitely be regarded as a low-cost airline, but compared to the low-cost air tickets of low-cost airlines that cost more than 100 yuan or even one yuan in seconds, the ticket of dozens of yuan like Bee is much more expensive, so it is no wonder that Shen Mo has a lot of grievances as a fan of Bee.

But when he passed through the open screen door and the cabin door, and sat in the little white belly, his resentment began to fall down because he had taken off. The route design of the bee is very conscientious, several main buildings, the famous big jelly are on the route, and the scenery is still very good.
