Crosman starts deliveries of a powerful sports and hunting pneumatic crossbow Pioneer Airbow. The product is based on the mechanism of the already existing and proven time of the Benjamin Pre-Charged Pneumatic pneumatic rifle, which includes a system for pre-injection of air.
The developer reports that the hybrid model is made in the style of Bullpap and is the first in the line of such devices. It is intended for use during the hunting on large and medium wild animals, such as moose, deer, boars. Another characteristic feature is the product does not require complex maintenance.
The initial speed of the rapidly stabilized boom is up to 140 meters per second. One injection of air is enough for 8 shots. In the standard set of delivery there are 3 arrows. All of them have a lot of 375 grams and are equipped with a special coating of Victory ICE based on nanocheramic.
Crosman Pioneer Airbow is equipped with a regular optical sight of a CENTERPOINT 6 × 40 mm with a MTAG measuring mesh. The user is available to the definition of aiming points at a distance of 75 meters. The total length of the product is 85.1 cm with a weight of 3.15 kg. The cost of the crossbow is 900 USD.

Hello everybody. I hurry more often in pneumatics sections. Luke / Crossbow is not my passion. Therefore, the request for the terminology is not cling.
In general, there was a reason to think: and not to buy crowns to me?
Patient Baska immediately began to kim: And is it possible to do it?
Of course, thinkers were used to see how and what, and how it is there on the bow / crossbow everything works ...
As a result, a scheme of a polyspasy crossbow on the GP was born.
Idea in the picture, nothing sly, everyone will understand.
However, an instrument and a bit of the theory, which is on the scheme and brought me.
I came to the conclusion that in order to obtain the missile for an Efmplic crossbow, it is necessary to strive for 2 conditions:
- the scope of "wings" needs to be done as little as possible;
- Spring Elenty must have as little as possible, the efforts of the effort is crushed / unfinished.
The theory picture is attached.
I think I did not first come to this conclusion. The principles work the Polyspaces.
And I simply, the conditions are suitable for Polyspas on the GP.
With an effort of a good crossbow in the cocked state of 80-100kg, the "platoon" in 40-50cm and with the presence of 2 winches of the polyspa, our GP should ensure the effort of 320-400kg in the course of 10-13 cm.
Make such a GP is quite real. Moreover, with the difference of effort less than 10%, which was hardly able to other springs onions and crossbows.
It turns out that "quitting" the wingspan of the wings to 8-10 cm and constructing the GP with a difference in efforts of less than 10%, it is possible to build an arbelt that will not be equal in the world.
(here is so modest 😊)
By the way, in the picture with the theory, the difference in the effort of the effort is crushed / near the "boom point" to the roller of the polyspa, I laid 20%. GP can be done with a smaller difference, but the "springs" will believe much worse (even for the best samples).
So in practice, the effectiveness of the GP-Polyasp will be much more than in the picture.
However, this scheme is quite molded and on the usual linear twisted spring instead of GP. But the difference of effort, seating ...
I did not do the construction of the prototype because it was not yet decided on the question: do I need an arbalet at all?
But I decided to throw the icekee in the masses - maybe someone will be useful.
brother 12.03.2014 - 12:51
Ran through the first 40 pages, looked pictures ...
I'm afraid I offered something fundamentally new.
Something that, with the same suspension, will shoot an arrow at least 2 times more than any of the options seen there.
Yes, and it will be much easier than most of the designs seen there.
Storm 03/12/2014 - 12:52
IMHO The second picture is wrong! Will there be a win in strength! Blocks must be movable !!! And so there is a direct transmission of effort.
brother 12.03.2014 - 12:57
I accept.
But this is even better - the GP should be at less effort.
brother 12.03.2014 - 13:01
Effectiveness comes from a very small scope of "Luke" and the corresponding corners of the application for forces to arrows during acceleration.
And also from a very small difference of the efforts of the spring, the springs of the springs / non-invisive, which GP provides.
And there will be an effort to intensify on the rollers or not not fundamentally.
PS: get the effort 100-150kg on the GP in general a piety.
PS2: And yes - the narrowing of the scope of the bow and "distance of overclocking" on which the overlay is applied to the arrows. Another factor for.
ADF 03/12/2014 - 13:11
A piece of polyspast in it is necessary. Otherwise, in the shown schemes, the spring will turn out to be mainly, and not the body.
ADF 03/12/2014 - 13:23
0. Arbents based on springs, including gas, not new among self-dealers. And they are all with blocks;
1. There is no such question where to take the refrigera on the bow. Because normal onions and crossbows are not made from the spring (because of the danger when they split, due to the large moving mass). Shoulders on any (!) Luke and Crossbows are easily bought, and to whom are not too lazy - pasted from composites with any desired characteristics;
2. Nonlinearity (although, according to the law of the throat, the spring force is just close to exactly the linear in the entire operating range) - never a problem or stumbling block.
brother 12.03.2014 - 13:29
bows and crossbows - from the springs do not doI asked for the terminology not to cling to: polycarbonate springs, remains spring in its form and the principle of action.
Nonlinearity (although, according to the law of a throat, the spring force is just close to it linear in the entire operating range) - never the problem or stumbling block.GP is also linear, there is no talk here. We are a small difference effort.
So that on the usual spring to get the difference of effort in 10% it is necessary to "compress" pre-90% of its ability to use only a range from 90 to 100%. For GP is not a problem.
brother 12.03.2014 - 13:47
1 Linear spring instead of 2 nonlinear "springs".Then I meant the nonlinear trajectory of the motion of the point of the application effort. (at the springs)
PS: In the classic onion, the scope is narrowed upon platform and, accordingly, increases with a shot. Accordingly, changing the angles of the application of the forces and reducing the effectiveness of the overclocking of the boom.
PS2: I believe that the unequal characteristic of the deformation / force of two different halves of the bow is also a factor of shooting accuracy.
brother 12.03.2014 - 14:05
I also knew 😀
The truth is difficult as !!!
I think the crossbow will be easier, and it is possible to minimize the scope. In the scheme about the theory, it is clear how much across the acceleration effect on the effectiveness of overclocking.
PS: I suppose that onions were designed for compactness considerations, and not the effectiveness of overclocking and simply subconsciously went the right way.
Ps2: By the way, I considered the closer pictures of that bows. There is a standard GP from the rack without a stock in volume. The difference of efforts 25% will be. Conclusion: Designers did not think about Effectiveness at all.

If there is a head and hands, and the impregnation of the pneuma, try without threads, immediately so that the piston pushing the arrow, reach 200 m per second, there will be happiness.
brother 12.03.2014 - 15:09
And here is the rights of the colleague:
spring will overclocate basically, and not a moisthamthe rod is heavy - the arrow is light ...
The presence of a working winch increases the effort on the spring by half, but twice the speed of the rusty. 2 Winches - 4 times ...
Polyspass not in vain invented ...
True, the transfer of speed from the guards to the Arret is a separate topic (picture with theory).
I agree that at the very first picture of the winch I did not succeed. And I wanted already 2 pairs 😊
ADF 03/12/2014 - 15:09
gunslk.
... immediately so that the arrow piston pushed
And there will be a piston to fly out after the arrow ... 😊
"The rope" (missed through the cunning blocks) in the onions and crossbows is not needed. It converts the movement of a slow and massive spring - into the rapid movement of a much easier boom.
In pneumatics, where gas springs are used, the link between the spring and the small poet is air. Spring and there does not push the bug directly - guess why! 😊
bratushka
... the difference of efforts with her 25% will be. Conclusion: Designers did not think about Effectiveness at all.
I say again: it is not (more uniform) effort throughout the work course - critical for crossbows and bows. At the end of the working stroke, the whole design (except arrows) should already be slowed down, overclocking - late and useless, no effort is needed. A group of accelerating force on the working part of the movement movement is perfectly configured by the Eccentric Blocks, especially since there are blocks and soyak, as the coeff increases. Transmission of energy from shoulders to the projectile. On top crossbows (type so-15), the ends of the shoulders are literally a few centimeters, with the course of the lameter and even more. And it starts the arrows with NSP 120-140 m / s.

ADF.Fat, does not go to the trunk?
Spring and there does not push the bug directly - guess why! 😊
gunsLK 12.03.2014 - 15:36
Well I did not write so that the spring pushed the bulk body, I wrote a piston.
Why does the spring can't push a thick piston? Why this thick piston, pushing air in a thin channel, can not convert slow motion into fast?
Why is the last piston can not be easy?
Why would the last piston not fly with a bolt and disconnect?
Why would this be a piston even not to pull out, but in the end of the trunk? (Such schemes have long been applied in a hasslement fireman)
Threads and shoulders limit the departure rate, since the speed increase comes to a single shots. Reducing the scope of the shoulders - loss of cuminess.
ADF 03/12/2014 - 15:50
Piston under the ass arrows - classic underwater guns, however. 😛
brother 12.03.2014 - 15:59
Under water, however ...
May and sound for you a paradox, but under water a slow and heavy arrow of much effergeful and with great initial speed.
gunslk 03/12/2014 - 16:07
Piston under the ass fraction, under the ass of the bullet, ... Container ...
Yes, ... probably more underwater theme ....
brother 12.03.2014 - 16:10
Threads and shoulders limit the departure rate, since the speed increase comes to a single shots.And we first increase the speed of 4 times, and then we lose a bit on the threads and shoulders 😊
Reducing the scope of the shoulders - loss of cuminess.If the shoulders 2 (as 2 independent springs / springs) and on them a different curve of effort - then yes.
And at one, and at 2 shoulders, much will depend on the quality of the rollers (their eccentricity, knocking in the bears ...) ... but this is a separate topic ...

In the fact that there are no propellers in Russian technical language. Ask any pilot - he will immediately explain that propeller - Karlson on the crap. 😀

And we first increase the speed of 4 times, and then we lose a little on threads and shoulders
..
It is enough to increase the speed at least 1.4 times, so that threads and shoulders scattered at different angles. They restrict them differently. 😀
brother 03/14/2014 - 10:13
Ento mustken ...
On the promotion of the rollers, too, Energia is required, the rope is longer and heavier (and it will also have to overclock it). The higher the speed of the rope - the larger the angular velocity of the rollers (the load on the bearings, which also slow down. It is not by chance that the driver is more serious - the greater the diameter of his rollers ...).
But Ento mustache shared diseases of all polyspars and the topic of a separate conversation.
brother 03/14/2014 - 10:29
By the way:
It is enough to increase the speed at least 1.4 times, so that threads and shoulders scattered at different angles.1.4 times about what?
I got to the video here, about tactical polyspas ...

The ratio of wings to the long platoon rushed into the eyes ...
ADF 03/14/2014 - 12:58
TAC-15 is a fairly well-known top cross, by virtue of its aggressive advertising.
But the main thing in it is that the left and right shoulder move when a shot in opposite directions and synchronized so as not to prevent unnecessary returns and unnecessary fluctuations in the system. Although this is not the only block, where the shoulders perpendicular to the direction of the shot are tight.
brother 03/14/2014 - 15:06
Yes, I'm talking about the speed that he gave gives ...
1.4 times to compare with it? Or with what other?
In terms of
so that threads and shoulders scattered at different angles

The ratio of wings to the long platoon rushed into the eyes ...We will demonstrate in pictures:
Cheap polyspas
Scope almost twice the platoon.
TAC15:
The platoon is clearly more scope.
Well, the diameter of the rollers ...

Many top blocks bully 120..140 m / s, Kak. But above 140 have not heard. Can 200 m / s do? 😊
brother 03/14/2014 - 16:42
120 - conventional arbal archers. Name the exact mass will not risk, so as not to lie ...
gunsLK 03/14/2014 - 22:03
bratushka
I met the usual arbal arrows in nete many: wooden, aluminum, on 14 ", 17", 20 ", with different tips ...
Not to mention the short for arbulent pistols ...
Everything is visible very different masses ...If they are all shitted with approximately the same speed - it may be fundamentally important for understanding the principle of work of the Cross.
So I ask the regulars - is it?

brother 17.03.2014 - 10:28
There is no answer to my question in the article.
Only confirmation of my assumption that arrows are very different masses: from 15 to 40 grams, the difference of masses is greater than 2 times.
The outer ballistics of arrows and how much the speed they "break off from the aunt" of the same crossbow / onions are not at all the same.
Apparently chronographs from the crossbars not in honor 😞

The peculiarities of the pistol type products should be primarily a very large external similarity with a gun. The design of a pistol type allows you to make shots with one hand, and is more compact sizes, unlike other types of crossbows. Powerful pistol crossbows have a light weight and small sizes. For this you have to pay the range of aiming shooting - in different models it can be from 10 to 18 meters. You can buy a powerful pistol brush for hunting. Our store provides a fairly wide choice. However, note that buying a pistol crossbow is a good idea for entertainment shooting, or for a gift for both an adult person and a child, however, you can hardly take a serious crossing with such an arbulence.
Pistol Crossets is an excellent light and unusual browse version. If you decide to buy a crossbow in Moscow, and do not know where to buy a crossbow inexpensive - you can explore our range and find for yourself the best crossbow. If you have any questions - you can always contact the shops of the store - crossbow many, they have different characteristics, and it is always easier to clarify the necessary information on the bristle-type crossbows from the manager! The Arbals of the AIR-GUN store (for example, the MK crossbow) is a wide selection of various types and designs, as well as various price categories. From the most inexpensive crossbows, to powerful and impressive hunting crossbows, whose price will be fully justified with the capacity of accuracy and a set of additional functions and "add-ons", which can be equipped with your crossbow. In our assortment there are different types of crossbows and a brush gun, and a pistol crossbow for hunting is a powerful pistol crossbow, darts for the bristle brush.
You can buy a Powerful Cross Pistol in our Armory Store Air-Gun in Moscow at a bargain price.
Also, here you will find darts for the brush type crossbow.
In this section of our online store, pistol crossbows are presented to your attention - a compact weapon intended for entertainment shooting. For you, we have collected the models of the most famous manufacturers: Interloper, Man Kung, Yarrow, etc. In the main mass of the bristy crossbow, these are recursive models of compact sizes with an effort of tension tension up to 40 kg.
As an ammunition, both darts or harpuna and metal balls can be used. Aiming range of shooting of some models reaches a distance of 30 meters. Pistol Crossbows - a great acquisition for any person, respecting active types of recreation. You can use this type of "weapons" in the room, and outdoors.
Many models are equipped with open sightseeing adaptations: entirely foam. The ability to adjust the sight will allow you to optimally adjust the crossbow under your characteristics. In addition, some pistol crossbones are equipped with Weaver Guide Plankers (Vaver), which can be installed collimator, optics or tactical lamp.
The small weight of the products does not strain the hand, it is possible to make a shooting arbitrarily for a long time. For secure use on all models there are fuses that exclude the possibility of an uncontrolled shot. If you want to quickly find the desired model, then with the help of a special filter system, you can sort all crossbows, for example, by the name of the manufacturer, rating or popularity.
Key features of Arbaletov
- Target purpose - entertainment types of shooting;
- Recursive type crossbows with tension force up to 40 kg;
- Ammunition: 6.5 "darts long", balls, harpuna;
- The range of aiming shooting up to 30 meters;
- The initial speed of the boom 50 m / s;
- The products are equipped with sighting devices of an open type (culk and fly);
- On some models there are Weaver Planks to install additional equipment;
- All products are equipped with locks, fuses;
- Materials: aluminum, composite, plastic;
- Compact sizes, low weight.
Constructive features of pistol crossbows
Among the design features of pistol crossbows, you can allocate the limiting ease of design and high reliability. The production uses only modern materials that can make all the charms of active operation.
The shoulders are made of superproof and flexible fiberglas, which does not lose its properties even after many years of use. The handles and trunks are made of aluminum alloys, and platoon-trigger mechanisms made of steel. It should be noted that for bringing weapons to the charged state, special levers are used, significantly facilitating the procedure itself. I am sure to use the crossbow even a child.
Composite shoulders provide a tension force of a tension of up to 40 kilograms, which in turn gives an arrow or dart to the initial speed of up to 50 meters per second. Such parameters are enough to ensure the targeted range of firing from 15 to 30 meters. The archery of the bristle-type crossbow is an excellent opportunity to get acquainted both with the wearage of the weapon, and to acquire the primary skills of the appeal, to learn such concepts as the ballistics of the ammunition and so on.
When using the Crossome, the necessary precautions should always be observed, one should not direct the weapon towards a person. Also look into other popular categories with weapons, among which you can choose certain armaments, accessories and additional equipment to it.
Why is it profitable to acquire bristle-type crossbows in the online store PNevmat24?

Team online store pneumat24
Pneumatic may be not only a gun or a gun, but also a crossbow. The simplest model of the pneumatic crossbow we will be with you today. Naturally, the fact that we will coordinate with you can not be considered a full weapon, and rather this pneumatic crossing will be only a model, on the basis of which the sleeve crafts will be able to make more powerful and functional weapons. So, proceed.
For the manufacture of a pneumatic crossbow you will need a wooden bar length about seventy centimeters. From the bar you need to spill the corner. This part will be designed for handling a pneumatic crossbow.
Further, we need to purchase syringe in a pharmacy by 60 ml (milliliters). Actually this syringe and will be our pneumatic crossbow system. In Broz, hesitically drink a small slot in order to insert the protrusion for the fingers of the syringe. The syringe to the bar can be closed with conventional adhesive tape (tape, tape).
We make the trigger mechanism of the pneumatic crossbow
Next, pull the piston of the syringe to 40 ml and put the label on the bar on the end of the stubborn plate of the rod.Near this mark on Bruke (now it can already be called a lie of a pneumatic crossbow), we will be screwed onto two screws a small piece of a wooden plate.
Next, you need to find a metal rod (rod) and under its diameter drill through a hole through the plate and. For the rod, you can use long bolts, which have a thread at the very end, which is then scolded. However, if you have a bolt with a solid thread along the entire length, they can be drowning on the sandpaper.
Now you need from the same wooden bar to cut the trigger arm of the pneumatic crossbow. At the edge of the trigger lever, we drill a hole under the diameter of the rod.On the bottom of the pneumatic crossbow bed, make focus for the trigger lever.
As a stop, you can fasten the same screws a narrow wooden bar or glue a piece of the same bolt to good glue, which we used for the manufacture of the rod. It remains to collect a pneumatic crossbow, consolidating its rubber.
We make a tutor for a pneumatic crossbow
Now we will need a medical harness as a taiga (traction). We measure the length as follows: I put it to the end of the bodice bed and stretch to the rod of the trigger, cut off and fold in half. Now the medical harness is twisted into the tube and grind the tape in the edges and in two-three places along the entire length. The edges of the harness we combine a solid cord (thick flush thread) ten centimeters long. The cord is tightened to the edge of the harness with the help of a node called in the spacious "removal".
We make a trunk of a pneumatic crossbow
Cut off a piece of dropper (it can also be purchased at the pharmacy, if of course you do not have familiar health workers who stumbled in such good for many years ahead) and insert it into the tip of the syringe. Compound Sealing with glue. Now we need to choose a tube for the trunk. The tube can be used any, if only there would be a bullet from pneumatics. The plastic tube from the blinds is ideal, but you can pick up your options.
Insert the second end of the dropper into the tube and we rush with glue again. The trunk tube is screwed to the lodge of the pneumatic crossbow, too, using adhesive tape.
There are two triangular groove on the stubborn plate of the Syringe (drink) so that they are one opposite another with their peaks. It is necessary in order that when a shot is not able to slip from the rod. For better slip, the piston of the syringe is lubricated with oil.
Principle of operation of a pneumatic crossbow
So, finally produce the assembly of our pneumatic crossbow. The thrust dresses on the end of the bodily of the crossbow (I think you guessed that for her there, too, it was necessary to cut a small groove) and starts the cord for the syringe, dressing it on the slots of the stubborn plate of the rod of the syringe.
Now the pneumatic crossbow can be charged. To do this, we pull the rod of the piston of the syringe and cling it for the rod of the trigger. Insert the pneumatic crossing in the barrel. Aim and click on the trigger lever. The trigger levets the rod down, the string is released, and the harness with force presses the piston into the syringe case. Under the pressure of the air charge flies into the goal.
Of course, if you do not have a pool for pneumatics, you can use homemade arbal darts instead.
Making darts for pneumatic crossbow
For the manufacture of darts of a pneumatic crossing, ordinary ears are excellent. You probably saw such: plastic tubes at both ends, which woven tamponchiks are wound. We remove cotton with one end of the tube and insert there a thick hollow needle. Needle's ear, despite the fact that it is tightly entering the tube better to lubricate glue. Frozen glue will not give the needle, do not fall further into the tube when shooting, nor jump out of it when delivered from the target.
The dart insert the end on which a cotton swab remains in the trunk, and we produce a shot. Of course, after a few wool shots, it will come into disrepair, so I would advise something to come up with a more durable thickening instead of cotton, but suitable for the diameter of the pneumatic crossbow barrel. You can offer your options. Good luck!
