Bogdan Khmelnytsky AGE: 37 OCCUPATION: MILLING WORKER HOBBIES: ARCHERY, WEAPON INVENTION
The inventor explains his exotic hobby as a banal coincidence. As a child, like all boys, he ran around the yard with an elastic band tied to a stick. Gradually got carried away sports shooting, which he has been doing for over 20 years. He shot from various bows, including the classic “Olympic”, simultaneously improving his professional metalworking skills. Bogdan was lucky with his job: during his lunch break he was allowed to do archery. However, the room was cramped, and it was impossible to turn around with the Olympic.
Then the idea of making a compact sports equipment. The first prototypes used rubber bands as tensioners. The result was not bad, but the rubber stretched and cracked in the cold. The “Phantom” bow (“PM”, No. 5 "2011) stored energy in a coiled spring from air gun and showed himself to be excellent. A year ago, Khmelnitsky came up with the idea of testing a gas spring - lighter and not requiring preload. The result is in front of you.
The envy of the industry
The Cobra frame is made of high quality steel using argon welding and is adapted to high loads. Without a sight and shelf, the bow weighs about 2 kg. The quality of weapons manufacturing is firmly associated with the highest industrial technologies.
The bow guide rollers are made on a lathe from aluminum alloy D-16T. The block is also made by turning, and then windows are made into it on a milling machine to reduce weight and fungi for attaching the bowstring. The module is molded from epoxy resin and fiberglass.
The arrow rack and scope are the only parts purchased for the Cobra. The hunting scope reminds us that a compact bow can be used not only for sport, but also for hunting. Three different-sized front sights in the sight are designed for shooting from different distances.
Force control
The Cobra has two bowstrings: the main one - the one that accelerates the arrow, and the power one - the one that connects the block to the gas spring.
The bow is built using a single block design - both ends of the main string fit into the wide groove of a single block. When the shooter pulls the bowstring, the block rotates 360 degrees (versus 180-200 for most sporting bows). This allows you to reduce the diameter of the block.
The module also rotates 360 degrees - a complex part with a spiral groove and a stop on which the power string rests. The eccentric-shaped module determines the nature of the bowstring tension. At the beginning of tension, its radius (read: lever arm) is large, and the force on the main string is maximum. As you tighten, the force decreases. Thanks to the spiral groove, the power string intersects with itself and rests on the stop. At this moment, the force drops by 2 kg and the bow is securely fixed in the cocked state, but this is not the main thing. What is more important is that after the shot, the force on the bowstring constantly increases and the arrow accelerates over a long period of time. This is why, at the same tension, compound bows give b? higher arrow speed than classic ones.
Energy transfer
It is not difficult to trace the path of the power string on the Cobra: it passes through two guide rollers (on the gas spring rod and on its body), one end of it is fixed to the spring body, and the other to a block near the module.
But figuring out where the main string lives is a puzzle worse than a Rubik’s cube. The solution is simple: both of its ends are attached to one fungus of the block, wound around it in one direction and lie side by side in a wide groove, like a lace folded in half. Together they pass through two guide rollers, and only then their paths diverge: one immediately goes to the upper roller through a fluoroplastic outlet (an inconspicuous white part that takes the bowstring away from the aiming line), and the second, obeying the archer’s steady hand, directs the arrow at target.
Source of power
Shoulders classic bow obey the same physical principle as a regular spring: the more they are bent, the greater the force they develop. This means that the tighter the bowstring is, the greater the force on it. The unevenness of the force is fraught not so much with the difficulty of aiming, but with the low speed of the arrow's flight: after all, the arrow receives energy in the form of a short impulse at the moment of the shot, and then the force on the string rapidly drops.
In the struggle for uniform draw, the Japanese built their 2.5-meter yumi bows with minimal bend in very stiff limbs. And Bogdan Khmelnitsky chose a gas spring as a tensioner for his Cobra, which already develops 75% of the force at the very beginning of the stroke. The maximum spring force is 50 kg, the minimum is about 40. Using a variable radius module, the inventor brings the already good characteristics of the spring to ideal: at the very beginning of the tension (after a small initial stroke of a few centimeters), the force on the string reaches 22 kg, and by at the end of the stroke it drops to 20 kg. After the shot, the arrow constantly accelerates, eventually reaching a speed of 85 km/h - decent result for a sports “blocker”.
Hello, in this article I will talk about the solutions to tasks and their passwords, which are available only to premium players (description of unlocking under spoilers)
To begin with, if you have Premium status, you need to unlock the completion of these tasks.
How to unlock
To unlock, you need to go to the leaderboards, then look for the shard on the bottom left and click on it.
You need to wait until the line stops running and enter a password to open the task, however, each phantom task has different passwords. ATTENTION - if you did not activate the password for the previous task, you will not be able to open the next one
[collapse]
1.Phantom object
How the password was found
Each of these figurines has Chinese numbers that can be converted into letters of the English alphabet and a password for this task can be created by guessing.
[collapse]
Password: bumpinthenight
After completing everything necessary, you receive a new token
2.Cadet-Phantom
How the password was found
Everything here is much more interesting than the previous phantom. The password consists of 3 words. And so, about the first word: On the “Islands” map from the Naval Strike add-on, you can find this locker with “kevinsimpson1942” written on it, but this is not a password, but a clue that is necessary on the way to the solution
By typing this phrase into a search engine, you can come across the site kevinsimpson1942.com. On the site, we hear some noise in the background. You can record it and present this track in the form of a spectrogram in a special program. Looking through this track, you can come across the word Epic, which is part of the task password
As you remember, we went to the website kevinsimpson1942.com and noise was heard there. But in addition to the noise, there was also a picture on the site in which the letters of the second word were encrypted
The first letter is the letter - D
It is encrypted in the bottle, which is located below and slightly to the right. The number 500 is written on the bottle - writing it using Roman numerals, we see this very letter D
Next letter is R
It can be found on the top left of the wooden door, which is in the distance in the picture. But we see it a little differently. Here it is provided using Morse code. Dot-dash-dot is the letter R
It can be found on a bright sticker on top of the picture. But it is also encrypted. The thing is, if you write the letter in Word e in the wingdings font, we will get the same letter that is drawn on the sticker
It is extremely easy to find. It is in the very foreground. It is formed from a roll of paper and a ladder
And the last letter is M
On the stairs you can find a scratched sign that is the letter M in the Viking alphabet
And so, our word is Dream
The last word we have left can be found on kevinsimpson1942's battlelog page. It is encrypted in his emblem, which depicts planets, or rather worlds, which, in English, would be worlds - the third word from the password.
[collapse]
Password: epic dream worlds
Now, having activated the password, you can start performing a new task.
And get a new coloring for completing it
3.Summon a phantom
How the password was found
Once again, we have a number of difficulties that led to a solution. Here, knowledge of mathematics will be very useful to us. To begin with, on the cards from the add-on we found such strange symbols - hexagrams and trigrams. To solve the solution, we had to pay attention only to the hexagrams (indicated in yellow numbers) 
Further, in July 23, they hired 2 new employees at DICE LA. And, as some guessed, they were connected with solving the password. Their avatar was of the great philosopher, writer and mathematician - Rene Descartes. Also, players paid more attention to employee with nickname jjju.Tk. on the boxes from which you can take the KVDR control panel, you could see his nickname. A little later, on the avatar of one of the new employees with the nickname jjju, a barcode was seen. Thanks to him, we learned that it is necessary to convert hexagrams into Unicode and this is what This happened - 0x4dc0, 0x4dc0, 0x4dc1, 0x4dc2, 0x4dc4, 0x4dc7, 0x4dcc, 0x4dd4.
Later they tried to reconcile this with the Fibonacci series and got this - 1 1 2 3 5 8 13 21. But this gave little, without knowing the sequence that was necessary. Later, thanks to the console where the password is entered, the “MAX” function was noticed, thanks which made it clear that it was necessary to write down in descending order.
Soon, the updated avatar jjju comes to the rescue once again. The formula indicated that we need to find a polynomial. But there was too little information and we had to wait for hints.
And here is our hint - the updated avatar of jjju.
From the graph you can see that this shows a function that tends to -? with the value -? and strives for? at value?, that is, the highest power of X is odd
X does not intersect the reference point. And if we look at the graph, the value of the function within the reference point will be between 19000 and 20000. This is exactly within the Unicode character range. This also tells us that the limit of the polynomial is x^0. We have 8 Unicode values labeled x^0 to x^7
Which in turn led the researchers to the console, where it was written “CHI = 7.25154120937236.” It is at this point that the function should be evaluated. The console also mentions the "floor" function, which indicates that we should ignore the decimal part of the result.
As a result:
f = 19924 * x^0 + 19916 * x^1 + 19911 * x^2 + 19908 * x^3 + 19906 * x^4 + 19905 * x^5 + 19904 * x^6 + 19904 * x^7
f(7.25154120937236) = 24344241893.00018
Round up and get the long-awaited password
[collapse]
Password - 24344241893
For completing the task you will receive a new camouflage for the infantry
4. Phantom operative
How the password was found
The solution to this task began with the console, which is in the battlelog
As people immediately noticed, you can’t enter a password here. But there is a phrase at the end that means that physical contact with something is necessary. But with what exactly is not clear. But soon 5 sound files were found, thanks to which a lot will become clear
1. "The elevator control is functioning"
2. "Access check in progress"
3. “Anomaly detected”
4. "Access granted"
5. “Hello operatives, welcome to the Phantom program!”
So, based on all these phrases (in the original they are indeed in Russian), it became clear that we need to find some kind of elevator and the very last phrase tells us that more than 1 person is needed. Soon that same elevator was found. It is located on the Hangar 21 map, at the end of a long tunnel in the hangar near point A. But, having entered this elevator, nothing happened. All we had to do was wait for clues. And so, on all 4 maps from the new addition, small boxes began to be found, breaking which with a knife you can get a token. About this mini guide
The next step was to activate the elevator. It turned out that in order to do this, a number of requirements must be met: 1. Gather a group of at least 4 people 2. Everyone must be wearing a token from the same box (the tokens must be different for everyone) and a token , which could be obtained for the first task of the phantom (token with a shard)
3.The phantom camouflage must be on the fighter and on the parachute
4.There should also be phantom camouflage on the main and secondary weapons
After this entire group entered the elevator, the light in the elevator came on and it became possible to press the button to descend. But an unpleasant surprise awaited them at the bottom. Between them and the bow (which is the reward for all searches) there was a force field and a button next to it to enter password.
But the password was already known a little earlier. Again, one more feature was found on all 4 maps. On each of the maps there are places where you can see or hear messages transmitted via Morse code. On each map there is one such place.
So, by making a combination of the numbers of these messages, we get the long-awaited password.
Once in this room we find the same bow
BUT! To activate the task itself, you still need to receive the combat orders for this task. They can be found in the same room, on the cabinet. 
P.S. If you find an error, please write in the comments
The Phantom program is one of the most complex tasks invented by game developers. It took a lot of effort to solve it large quantity players. This section describes how this puzzle was solved.
Note: Premium membership is required to unlock this challenge.
Object-Phantom
The story began with the addition "", in which the task "Phantom Object" was added, but as we know, this task does not have requirements. Players began searching for a solution to this puzzle, and eventually they found strange figures on the maps of this expansion.

Each figurine had Chinese numeral symbols on its leg with dots; the players matched these digits with the letters of the English alphabet and received a set of letters. Through trial and error, they came up with the phrase " BUMPINTHENIGHT". But where should I enter this password? The search led to the leaderboard page in Battlelog where a phantom symbol was seen in the corner.
By clicking on it, the console was launched, where the given password matched and the “Phantom Cadet” task was successfully unlocked.
In the next addition "" another task from the phantom series was added, "Cadet-Phantom". The players immediately set off in search of a solution to the next riddle. The search led them to a locker on the “Island” map, which had the inscription “kevinsimpson1942” on it; using a search engine, they went to the website kevinsimpson1942.com, which had a strange image and an equally strange background sound.

Opening it in the editor and switching the view to the spectrogram, they found the word “epic”, but this was only part of the password. The next search led to the profile of kevinsimpson1942 in battlelog, in whose profile poems appeared daily, in addition to the poems on the emblem of this fighter, each time a planet was added. The final verse said the following (translation):
Phantoms. It was my duty. Now my road is coming to an end
Our paths are unlikely to cross again, but I know you will break through.
The world must know our reasons, and you must take back what is yours.
Your key can be found in the information
Don't go into the battlefield, it's not safe there. Let the key lead you to the prize
xxxx xxxxx xxxxx
###End of transmission
As is clear, the set of X’s is actually the password, the first word consists of four letters, here the players remembered the very word “epic”, the next word was led to the very same poems that talked about a dream, i.e. in English “dream”. The last word was hinted at by the emblem of this fighter, on which the planets were updated daily, which prompted the word “worlds”, i.e. “worlds”. And as a result, we have the password “epic dream worlds”, entering this password activated the task “Phantom Cadet”

"Phantom"In the next addition, namely “”, the next task of the phantom “call the phantom” was added. Searching the maps for this expansion led to strange signs. As it turned out, these are hexagrams and Chinese trigrams IChing. A little later, a barcode was seen on the avatar of one of the new employees with the nickname jjju. Thanks to him, we learned that we need to convert hexagrams to Unicode. After which we received - 0x4dc0, 0x4dc0, 0x4dc1, 0x4dc2, 0x4dc4, 0x4dc7, 0x4dcc, 0x4dd4.
Soon the avatar of jjju was updated. The formula on the avatar indicated that we needed to find a polynomial. But there was too little information and we had to wait for clues.
And now, a new update of the jjju avatar.
The graph shows that this shows a function that tends to -∞ when the value is -∞ and tends to ∞ when the value is ∞, that is, the highest power of X is odd
X does not intersect the reference point. And if you look at the graph, the value of the function within the reference point will be between 19000 and 20000. This is exactly within the Unicode character range. This also tells us that the limit of the polynomial is x^0. We have 8 Unicode values labeled x^0 to x^7
Which in turn led players to the console, where it was written “CHI = 7.25154120937236.” It is at this point that the function should be evaluated. The console also mentions the "floor" function, which indicates that we should ignore the decimal part of the result.
As a result:
f = 19924 * x^0 + 19916 * x^1 + 19911 * x^2 + 19908 * x^3 + 19906 * x^4 + 19905 * x^5 + 19904 * x^6 + 19904 * x^7
f(7.25154120937236) = 24344241893.00018
By rounding they received the long-awaited password

The final part of the font tasks was added in the "" add-on. But now the console did not require a password, it said that physical contact with something was required. But with what and where it was not clear. Skilled players dug out a five-sound file in the game files that said something in Russian (in the original they are really in Russian).
- "Elevator control is operational"
- "Access check in progress"
- "Anomaly detected"
- "Access granted"
- "Hello operatives"
The search for this elevator immediately began on the new expansion maps; the search led to a non-working elevator on the “Hangar 21” map. But how to activate this elevator?
 |
|
 |  |
With a recent expansion, new tokens were added to Battlelog, but they have been closed. The next search led to cardboard boxes scattered across new cards, hitting them with a knife revealed these tokens. Now everything is clear, we put on the tokens and head into the elevator, but it didn’t work. As we remember, those sound files say “.. operatives,” which means the player must not be alone. Through trial and error, players found out that in order to activate the elevator, there must be four soldiers in it wearing “Phantom” camouflage (on weapons too) and with “Phantom” tokens. Taking the elevator down, the players discovered another barrier, a force field and a panel to deactivate it, and again they needed a password. Having studied the map again, the players found blinking dots and simply places with strange sounds transmitting a signal in Morse code, by translating them they received the following messages:
"1290" EVERYTHING IS NORMAL...THE TRANSMISSION STARTS...PROGRAM CONTROL COMPLETED...
"429" WE WILL DEPARTURE TOMORROW MORNING... WE START PREPARATIONS FOR A NEW EXPIDITION...
"397648" WE NEED REINFORCEMENT...WAITING FOR YOUR REPLY..
"970" FACTORY SQUAD EVERYTHING IS OKAY...WALKER SQUAD IS NOT READY...THEY DID NOT SUSPECT ANYTHING..LET'LL WAIT...
The password was successful and the players received the long-awaited reward, but the task was not activated; to activate it, they needed to climb onto the cabinet in the room with the bow and pick up the document from there.
How to get the Phantom bow without having to look for tokens, beg friends and go down to the secret room on the Hangar 21 map? The answer is in the video from LevelCap, translated and voiced EAshooters.ru
Text version
Hello guys. LevelCap is with you and today I’ll tell you how to unlock the Phantom bow in just a few seconds by playing on the “Operation Riot” map. All you have to do is enter it in the “Grand Capture” mode on an empty server, land in the center of the map and go towards this cave. I'm not sure that this is really a cave, but it looks like it. Walk up to this box and stab it with the knife. At first you will be blinded, and when this passes, you will see that there is a Phantom bow inside. All you have to do is come up and pick it up - now your bow is unlocked. This is permanent, the bow can be used on any map. In addition, it comes with a new arrow with a poisonous tip. If you're wondering what this poisonous tip can do, let's take a look right now.
First, it deals a small burst of damage, and then the enemy continues to receive damage for some time. In this way, you can inflict 50 damage to the enemy - first with an explosion, then, little by little, with poison. But the truth is that poison cannot kill anyone. You can eliminate an enemy who has, say, 30 percent health with an explosion. If you hit him with an arrow, then after all the effects are applied, the enemy will have one or two percent of his health left.
Let's be honest - the Phantom bow was never even close to the title good weapons. I can only add that poison arrows are one of the worst options I've tried. I used it in Team Showdown and tried to get kills, but it was very, very weak. Most often, I was awarded “assist in killing” at 20 or 23 points, and I was able to kill very rarely. Most often - by detonating some kind of explosive near the enemy. You have to shoot so many arrows at the enemy to eliminate him. Well, or he should have 20 percent of his health left when my arrow arrives.
I suspect it's possible to successfully remove half an enemy's health by using poison arrows and then finishing them off with a pistol or something. But I think it takes away from the fun of using the bow. You probably want to kill with a bow - and this is incredibly difficult to do with a poison arrow.
Just to give an example - this is how long it takes if you shoot arrows directly at the enemy with maximum speed. Hitting the head does not provide any advantage. So yeah, good luck with the shooting. Of course, a bow is more of a trolling weapon than anything effective. But now it is very easy to get it. Enjoy the Phantom bow on the Operation Riot map!
And, as always, thanks for watching. See you next time. LevelCap was with you. End of connection
