Chapter 054 is low-key

Because of seeing the black technology, Boss Dong has more confidence in Boss Wang's real room, and it seems that Boss Wang is not an ordinary boss, and he is more confident in his skating, flying and plane.

When he had time, he came to see the progress of Boss Wang's various products. This day is a good day for the trial flight of the gliding drone, and Boss Dong also came to observe.

After doing it for so long, the three pattern youths in charge of this project were very excited, and they came out with more than a dozen curious friends to watch.

The urban-rural junction is good, and not far away is the field of hope, empty and spacious enough.

The first step is to test gliding at an altitude of 100 meters, which is expected to fly 5 kilometers and, of course, hover over the starting point.

There is a board hanging under the hydrogen balloon, which is the place where the glide, glider, and plane are parked, and the plane is fixed with a shelf, and then released when it is in the air, and the board with a slope will slide the plane out, and the structure is simple and reliable.

A young man with many years of experience in playing drones controls gliding, gliding and airplanes, Wang Zhan does not have this skill, and hopes to land on a road near them without using the low-forcing technique of popping out a parachute.

"100 meters." Wang Bang heard a clanging sound, and the set rope was stuck.

With a cheer, the glider slipped out of the skateboard and drew a straight line in the sky.

There is a program in the flight control zhì to rotate according to the gyroscope, and it is tested well in the real room, but I don't know how the table is in the real scene.

Turned, but it doesn't seem to be very reliable, it's too big, it's normal, the program is learning, after a few turns, the glide and the plane will master the heat, this is the power of Wang Fang's evolutionary algorithm, in the opinion of Boss Dong, I thought the test was a bit a failure.

In the first test, he fell 80 meters away. Everyone rushed over to pick it up and check the injury.

In the second test, the landing site ran within 10 meters, and the progress was amazing.

Third, the height of the test was put to 500 meters, which made people wait for a while.

At this altitude, the turbulence was finally encountered, and Wang Fang saw abnormal fluctuations on the sensor number, and the person in charge of observation saw a violent shaking in the telescope and almost stalled.

The automatic control system is stable and the fuselage is stabilized! It was a great victory, and Wang Bang rejoiced.

After a long wait, about 20 minutes later, the glide plane landed safely, 30 meters away from the release point, and the error was completely acceptable.

Why is it important to circle around? Because it is impossible to arrive at the customer's designated place just when the delivery is made, the other party is waiting there, and it is necessary to go around in circles.

The next test item is a 180-degree U-turn, which is also completely self-learning from the gyroscope, and automatically corrects the preset parameters.

Of course, this is also an important project, and it is a turning point for returning home after delivery.

The circle is done, the U-turn is not a problem, the first U-turn is successful, the deviation is 5 meters, and the course correction has not been started.

It is very difficult to develop a channel correction, because it needs to be accurate, and GPS is not very good, and if you put gliding, gliding, and aircraft into the actual scene now, the estimation deviation will be very large, and GPS is very unreliable. Now Wang's team's plan is to use crude black-and-white photography to quickly make temporary images, and to determine their position through before and after comparison, to put it bluntly, they use aerial photography to navigate in the sky, which is similar to the principle of Tomahawk missiles.

Three days later, the course correction system was initially completed, and the lads couldn't wait to come out to test it again, this time, they had to fly 10 kilometers and come back, in order to be reliable, they would set the take-off altitude to 1000 meters, theoretically they could fly 50 kilometers without wind, and it was more than enough to turn back 10 kilometers away.

The first long-distance flight encountered a thrilling scene, encountering a strong crosswind at a distance of 8 kilometers, and the guide zhì glided, soared, and fell like a plane in free fall. After falling a few hundred meters, the automatic control system that adjusted the position miraculously stabilized the plane, and the young men who held their breath breathed a sigh of relief.

Everyone looked at Boss Wang, and Wang Bang smiled slightly: "It doesn't matter, there is an updraft at a distance of 5 kilometers, hovering there to regain altitude." ”

In the midst of all the attention, everyone found that the updraft that had just been recorded was still there, and aerial photography of Guò found that there was a power station there. Interesting.

The stall self-rescue system actually worked, and this test was really rewarding, when the glide plane regained altitude, the guys shouted in unison, feeling as happy as if SpaceX had successfully recovered a first-stage rocket for the first time.

A very witty young man said: "I found that the updraft has one every few kilometers, is this a coincidence or a pattern?" ”

Sure enough, it was a little friend without culture, Wang Bang said with a smile: "This is called LeeWave, leeward air waves, well, the Chinese name is tentatively set for this, the wind forms an updraft when climbing, presses down the air flow on the back, and the air that is pressed down lifts up the air several kilometers away, forming wave after wave of air waves, and this air wave effect may also be formed near the power station just now." ”

Everyone bowed down. "The boss is erudite!"

All in all, the Glide, Fly, Plane Crossing is back! The boys at the origin cheered again. Deviation: more than ten meters!

Wang Bang smiled: "I was almost about to pop out of the parachute just now, for fear of hitting someone else's head." ”

A guy smiled: "It's a vegetable field there, no one should be so unlucky, right?" ”

Wang Fang: "That's not necessarily, maybe the vegetable farmers are working in the fields." ”

The diameter of the urban area of Recheng is only about 10 kilometers, and their gliding drones can reach any point in Recheng smoothly, which seems to be very powerful.

Similar tests will continue, but they are already imagining how they will deliver packages in the future.

Wang Fang had already thought about it, and said: "We use plastic bags to make parachutes, tie them to the package, and when the package is dropped, it will automatically inflate and unfold, and it will see if the airdrop can be accurate." ”

It's hard, it's hundreds of meters high. And, what if the parachute is not deployed? Isn't the probability of knocking people down in the city soaring? The outlook for large-scale adoption is bleak.

But because it was so fun, these heartless boys happily went to study the ballistic curve of the bomb, which had to take into account inertia, wind resistance, wind speed, weight, etc., which was complicated.

Wang Bang thought, I'm afraid that only airdropping weightless things like "bitcoin banknotes" is reliable, and it is impossible to cause an accident.

An idea is brewing in my heart, I am afraid that airdropping in the city is not good, only the development of the rural market, which is just the current express industry shortcomings.

And, suddenly, it feels like it's time to take a good look at the distribution of power plants? In particular, thermal power plants basically have updrafts, so if a nationwide updraft map can be established, wouldn't it be a glide, glider, and plane traffic map?

You know, there are tens of thousands of large-scale thermal power stations in China!

As soon as Boss Wang gave the order, the young men began to work to collect the number of power plants.

There are only a few thermal power stations around, and the next day, Boss Wang tried to let the glide, glider and plane do a tour flight in several thermal power stations near this to see if it is reliable.

If the circuit flight of the nearby thermal power station is reliable, it can basically be asserted that the national tour flight is also reliable, and the extremely subversive drone program is so high that it is higher than the quadcopter or something.

No one knew about Boss Wang's ambitions, and a few bear children didn't find out, they just thought it was fun. After all, the airdrop package is unreliable no matter how you look at it.

The young man in charge of developing the wrapped parachute is giggling and making his own parachute out of nylon fabric, and he is very familiar with the embroidery needle.

These crooked parachutes don't look like they are extremely reliable, and if you are a big living person, you will never dare to use them for parachuting.

Looking for a dedicated supplier? No way, it's too expensive.

These young men have not yet made a parachute, Boss Wang personally designed, with a dozen air bags strung together a rotary parachute has been launched, after testing, a kilogram of boxes can land lightly, because the air bag combined into a turntable can be a large area of the wind and rotate, so the air attitude is particularly stable.

The boys were dumbfounded, the cost of a dozen air bags was only a few cents, and it was particularly easy to make, and chimpanzees could learn it.

Boss Wang also set a special positioning method: use the LED light on the back of the mobile phone to irradiate the drone, cooperate with the app, and the drone will be airdropped at the place where the LED emits a strong light, and the deviation is less than 10 meters in the absence of wind. Basically, it can be used in one place.

On this day, Boss Dong brought several partners to observe, full of interest in this novelty.

Several of them gave the project a maximum valuation of 10 million, and Boss Wang smiled silently.

At this time, a young man sent a WeChat message and said, "Boss! Our glide, glider and plane have flown more than 3,000 kilometers, which is about to break the world record! ”

Boss Wang pretended to be calm: "It's good, keep flying, you can switch to automatic cruising if you are sleepy." ”

When several investors heard the news from WeChat, they were shocked, Boss Dong: "What 3,000 kilometers?" How can it be so far? ”

Boss Wang smiled: "It's nothing unusual, I encountered an updraft." ”

A Mao boss surnamed Mao: "Have you ever dropped your plane?" ”

Boss Wang: "No, it's really lucky, I almost fell off once, but I actually recovered again." ”

Boss Mao: "It seems that the flight control system is very good." ”

Boss Wang: "Ours is a glider, glider, and aircraft, basically there will be no motor maintenance, which can save a lot of money and maintenance energy, and ordinary drones will be wasted after flying 3,000 kilometers." ”

Boss Dong was excited: ", yes, 3,000 kilometers, it's too awesome, it's awesome!" You should let the media hype it up, do you want me to arrange it for you? ”

Boss Wang waved his hand again and again: "No, no, no, low-key, low-key!" This is just a joke, not a practical thing. ”

Boss Mao: "Also, gliding and flying planes are no different than ordinary drones, and they can't land to deliver packages, which is always not a problem." ”
