Chapter 253: Bionic Bird Flying Machine

Spies are characteristic, and in some ways very obvious.

First of all, the appearance of this kind of person is often very ordinary, the kind of person who will forget it at a glance in the crowd, because they don't want to attract anyone's attention, and even many people have always played the image of a good person and an honest person.

Of course, it is also possible that it is really the same as in the movie, he is a handsome man, and then in the process of messing around with flowers and grass, he completed the special task assigned to him by the organization.

No one can guarantee that when people think that spies are low-key, they will do the opposite and strengthen some of their "labels", which will not attract the attention of others.

Even if it catches the eye, it will be thrown into the "exclusions".

After all, in people's consciousness, spies must be low-key.

"Oh, did you say that handsome man? It's impossible, the spy can't be so flamboyant, it's just like in the movie. ”

Then, these people often have very free working hours, so to speak, they are basically not seen working, but they are hanging around, and they have always appeared in important places.

They're basically people who work in a vague way, wear multiple titles, and have a lot of money.

However, if the mission has a clear goal at the beginning, they will also be fixed in one place, such as going to work in a certain place, etc.

They need to get useful intelligence from all over the place.

Last but not least, many of these people are international students who have studied abroad in multiple countries, or who have studied abroad in a way that does not match their age.

They have a lot of experience and knowledge, and they always talk to attract the attention of others, and they must be very good in a certain field, so that they can reach out to more people at the top and try their best to find out some of the information they want.

They often participate in various academic seminars and business conferences, often throw out reactionary remarks, exaggerate the benefits of foreign countries, and take the initiative to talk to and make friends with others.

They also like to throw up controversial topics in public gatherings, cause arguments, and then spy on the crowd.

He also often cares about and asks sensitive questions about the people around him, not only in the political, military, public opinion, business and other areas.

How's that, does it feel familiar?

Where have you seen it?

That's right, on the web.

Sand sculpture netizens are more or less in line with the characteristics of this aspect.

Their chats can often span multiple industries, and they can be so content that you don't know what to call 666.

On the National Security Education Day, the TV station said that everyone should pay attention to counter-espionage, and then said these characteristics, which made everyone on the Internet sand sculpture netizens feel at risk, and at the same time a little happy.

Because everyone looks like 500,000.

Of course, he is also like 500,000 in the eyes of others.

This meme comes from the "Measures for Rewarding Citizens for Reporting Clues on Espionage Behavior".

According to the reward measures, where citizens report espionage acts that play an important role in the detection of espionage cases, the state security organs will reward them based on the actual situation.

The reward is divided into three grades, 10,000 to 50,000 yuan, 50,000 to 100,000 yuan, and more than 100,000 yuan, with a maximum of 500,000 yuan.

Of course, false accusations against others will also be punishable by law.

This situation is not very clear inland, but coastal fishermen have been able to participate solidly and win awards.

For example, after Merriken's warships came to the surrounding ocean area of Tianxia, in addition to the warships of the Tianxia Navy followed, a large number of fishing boats followed along.

However, this is probably better distinguished from the hidden spy on the Merriken's warship, after all, the national flag is hung on the warship, and the spy does not have "spy" written on the door of his head.

Although those characteristics are written, professional spies only show them in subtle ways, and even the characteristics are fleeting.

After all, no matter how strictly trained agents are, they are human beings in nature, and some human "problems" cannot be changed.

Ordinary people can't see the difference at all, they will only think that the other party is a sand sculpture netizen who is on the line with them, or bragging.

Only some "old agents" who do the same job, and who have to work for decades, can find some clues in the crowd and say, "I smell my peers, they're here, we're busy." ”

And now Tang Chao used the power of science and technology, and even a little sign of black technology, and soon found a lurking spy in the crowd.

"BOSS, please look at the bald head five meters in front of you, he is a typical agent performance, although he is looking around like everyone else, but his purpose is 60% higher than that of ordinary people, and in the process of looking around, there is a 47% chance that he will look at the door of the press conference......"

Tang Chao walked in the crowd, and the butler's voice prompted him in the headphones, asking him to pay attention to the marked spies.

He came down the staircase where he could see the whole situation, because there were two spies on the stairs, and his purpose was not just to come here to see, but to find little Armstrong and talk to him.

Now little Armstrong is definitely no longer here, as can be seen from the previous video, he is well protected, and he is treated with the "hero" who exposed the Prism Project before, and it is Merrican that is guarded.

However, from the perspective of observation provided by smart glasses, and the technical support and analysis carried out by the housekeeper, Tang Chao found a lot of details.

He wanted to meet the little Armstrong, but he didn't know where the other party was, but fortunately he was not the only one who was looking for someone, and he could find a way to use the intelligence network of those spies.

After identifying a few marked personnel as spies, he returned to the hotel, returned to his room, and immediately went to the bathroom.

An hour later, he came out with two large boxes, and when he opened one of them, it was not a grenadier or a bazooka, but a black crow.

They weren't real crows, they were all mechanical crows, ten in all.

From the outside, they don't look mechanical at all, they look like a common crow, but in fact they are ornithopters.

Ornithopter refers to a heavier-than-air aircraft whose wings can flutter up and down like the wings of birds and insects, also known as thopters.

A flapping wing creates not only lift, but also forward thrust.

For a long time, people thought about imitating birds to fly into the sky, and in the spring and autumn of Tianxia, there were attempts to create flying wooden birds, da Vinci also sketched ornithopters, and many more ornithopter designs that people didn't know about.

However, due to the problems of control technology, materials and construction, the ornithopter remained at the stage of model making and conception for a long time.

Technology has advanced to the point where it has been possible to create ornithopters that are close to practical.

In principle, these aircraft can be divided into imitation bird flapping wings and imitation insect flapping wings, mainly micro-small unmanned flapping wings, and there are also large manned ornithopter test flights.

The flapping frequency of imitation bird flapping wings is low, the wing area is large, similar to bird flight, and it is relatively easy to manufacture.

The frequency of imitation insect flapping wing is high, the wing area is small, and the manufacturing difficulty is high, but it can be easily hovered.

Although modern flapping wings have been able to achieve better flight and control, there is still a certain gap from practicality, and it still cannot be widely used, and can only be used in some tasks with special requirements, such as small space reconnaissance in urban anti-terrorism.

The main problems that need to be solved in flapping wings are low aerodynamic efficiency, high power and mechanism requirements, high material requirements, and small payload.

Taking the aerodynamic problem as an example, the micro-flapping wing is a low-Reynolds number and unsteady process, and it is still impossible to fully understand the flow model and accurate aerodynamic changes in the flapping wing flapping process, and there is no perfect analysis method that can be used for the calculation of the flapping wing aerodynamics, and the related research mainly relies on experiments.

Today's ornithopters are already very good, and many companies and individuals can easily make them, but they are basically toy-level, and there is still a big gap compared with real birds.

Not to mention surpassing the birds.

They can be shaped like all kinds of birds, but they are not as agile as birds, their wings flapping at a stiff angle, and they need to be thrown by human or mechanical force to take off, and they cannot land like birds.

Some bionic birds don't even have claws, and they can't stand or restrain their wings, so they can only spread their wings and stand up.

The crows that Tang Chao is holding now do not have these problems, and it can imitate birds almost perfectly.

It can imitate birds taking off, landing, standing, walking, and bunkering their wings, although a little stiff, not as dexterous as real birds, but as long as they stand in a corner, occasionally move a few steps, twist their heads, no one can notice that they are different from real birds.

In addition to these, it is inherently powerful, and its flight speed far exceeds that of crows, reaching 100 kilometers per hour, which is close to the fastest bird in the world.

Its size allows it to carry a heavy battery, allowing it to be active for more than 10 hours, which is why Tang Chao is not suitable for insect spies.

Although the artificial insects are smaller and less easy to spot, their size limits the size of the battery, and they can fly for a few minutes before taking a break.

As for the concealment of crows, there is no need to worry at all.

As the number of visitors increases, the food left behind by the tourists or the food they are specially fed attracts a large number of crows, and the acids in the crow droppings can cause damage to the various golden domes in the city of a thousand peaks, as well as leave marks on the clothes of the guards and tourists, which is very uncomfortable.

For this reason, Maozi has set up a special unit to train eagles to drive away these annoying crows.

Tang Chao's bionic crows flew around in this situation, no one would care at all, and even if they were targeted by eagles, they could also emit special sound wave frequencies to expel these eagles in reverse.

This kind of powerful and useful thing, which can't even be detected by radar, is definitely the most compatible thing with spies, but the earth's technology limits the scope of its use, so that it can only be majestic in spy movies.

Now, Tang Chao is going to use them to deal with spies, and he has become a "super agent" in the movie.

It just so happens that decades ago, the male agents of the White Bear Alliance were called "Crows", and the female agents were the famous "Swallows".

He opened the window of the room and looked outside, there were not many people on the street, and no one noticed that someone upstairs had opened the window, so he put the bionic crows on the windowsill one by one and let them fly away on their own.

"Fly, fly, under the guidance of the satellite, go find the target I have marked for you."

After the ten simulated crows flew out in turn, Tang Chao closed the window again.

There was a "housekeeper" behind to direct the ten bionic crows through the satellite, asking them to find their respective targets, Tang Chao was very relieved, and after looking at the flight status of the ten crows with only glasses, he went downstairs to eat.

It's 6 p.m., it's almost dinner time, and the crows are 10 hours old, so from now until 4 a.m. tomorrow, it's their activity time.

Tang Chao was not in a hurry at all.

There are activities in the evening, so he has to eat a little more for dinner, but fortunately, their accommodation costs include three meals, and they are all buffet, so he can eat openly.

In November, the temperature in the city of a thousand peaks has entered below zero during the day, and it is even colder at night, so Maozi's three meals are very high in calories, all kinds of meat, jam, caviar, desserts, and indispensable wine, which create their physical state.

According to scientific research, the higher the latitude, the stronger the creature, and Maozi is precisely in the high latitude area, and it is not surprising that people are generally tall and big.

Because of this, they need high-calorie food more than us to maintain their body functions.

Of course, the ingredients are also different, often a sheep, half a cow, with simple onions, potatoes for roasting, meat and vegetarian matching, roasted and eaten, these "extremely high-calorie" food, is simply a typical representative of the Maozi diet.

"Meat and vegetables" are eaten together, which is also considered to be the level of "folk meal" in the local area, although not every family is so "arrogant", but meat is also an indispensable food on their table.

The reason why you can eat meat so "unscrupulously" is because the yield of Maozi's "bean grain" crops is very high, and these crops can be used as feed, and the cost of the farm is naturally low, such as pigs, sheep, cattle, chickens and other meats, which will be much cheaper than in China.

Of course, don't think that a meal with big fish and meat is happiness.

This extreme living environment and unbalanced eating habits often bring greater disadvantages.

The only vegetables that can be grown locally on a large scale are potatoes, tomatoes, cucumbers and so on, and more fruits and vegetables are mainly imported, and the price will be several times more expensive than in China.

This also follows the rules of biological evolution, the temperature is low, and if you still eat vegetables as the staple food, it is estimated that it will be very difficult to survive the winter, so you can only eat more meat to supplement calories.

This is also why many Mao girls have a good figure when they are young, but after getting married or having children, and then not managing their bodies well, they will quickly become strong Maozi aunts.

When Tang Chao came to the restaurant, there were already many people here, and he could also see all kinds of sumptuous food on the table.

Unlike the cold outside, the atmosphere here is quite warm.

"Hey, Tang Chao, come on, can you eat meat, this is simply a paradise for carnivores!"

"Come on, come on, it's all big pieces of meat, especially this barbecue is quite delicious, very in line with the taste of our Tianxia people."

"This red sausage is also good, not bad as what we eat in the Northeast."

"Let's try this caviar, this is really delicious, so delicious!"
