  • Topics on Archery Mechanics Joe Tapley
    Topics on Archery Mechanics Joe Tapley Topics on Archery Mechanics Introduction The basic physics of archery has in principle been understood for around 80 years. The last topic to be theoretically described was vortex shedding (aerodynamics) in the 1920's related to developments in the aircraft industry. While the principles of archery are understood, in practice the behaviour of the bow/arrow/archer system (termed 'interior ballistics') and the arrow in flight (termed 'exterior ballistics') are somewhat complicated. In order to understand the mechanics of archery computer models are required. Models related to interior ballistics have been developed over the years becoming more realistic (and complex). A few related papers are listed below: Kooi, B.W. 1994. The Design of the Bow. Proc.Kon.Ned.Akad. v. Wetensch , 97(3), 283-309 The design and construction of various bow types is investigated and a mathematical model is used to assess the resulting effects on the (point mass) shot arrow. Kooi, B.W. & Bergman, C.A. 1997. An approach to the study of Ancient Archery using Mathematical Modelling. Antiquity, 71:124-134. Interesting comparison between the characteristics and performance of various historical and current bow designs. Kooi, B.W. & Sparenberg, J. A. 1997. On the Mechanics of the Arrow: Archer's Paradox. Journal of Engineering Mathematics 31(4):285-306 A mathematical model of the behaviour of the arrow when being shot from a bow including the effects of the pressure button and bow torsional rigidity. The string forces applied to the arrow are derived from the bow model referenced above.

Editorial by Morten Wilmann, Chairman Dear Judges, When writing this editorial we are just up front of the Olympics. For judges on duty for that event, it is starting to be a bit thrilling. Some athletes are saying that this “is only one event like other events”, and some may regard it as such (although I doubt if they manage). In spite of recent news about extensive doping in some sports and in some countries, I still think that the Olympics stands out as a very special event, well regarded and connected with “personal glory” for the winners. Archery in the Olympics 2016 – in Rio de Janeiro, Brazil – takes place in the famous street of the Sanbodromo where the carnival regularly takes place, again a rather iconic place for archery. These are surroundings that may add some thrill to the competition, and your committee is confident that our judges will perform at the same top level as the archers – in spite of the possible stress of the moments.

  • Discussing Draw Length
    Discussing Draw Length The "Perfect" Draw Length Your own "perfect draw length" is the draw length setting at which you are the most comfortable and the most accurate. There is no right and wrong, no absolutes. But it is unlikely that a 5'10" guy will be successful with a 30" draw length, and similarly unlikely that a 6'3" guy will shoot well with a 28" draw length.......not impossible - just unlikely. For some, a "perfect draw length" may be ultimately determined by feel (and some trial and error) rather than by calculation. However, we still recommend a common-sense approach here. If you're new to the sport, you'll have better luck if you just play the averages and choose an initial draw length that's similar to others of your same size and stature. Fortunately, on most bows, making a minor draw length change is pretty simple. So it's not quite a life or death decision to start. However, as you become more immersed in the sport and begin to "fine-tune" your game, you may wish to experiment a little with your draw length. Why Draw Length Matters More Draw Length = More Power The longer your draw length, the longer your bow's power stroke will be - and the faster your bow will shoot. As a general rule, 1" of draw length is worth about 10 fps of arrow velocity. Bows are predominantly IBO Speed* rated at 30" draw length. So if your particular bow has an IBO speed of 300 fps, and you intend to shoot the bow at 27" draw length - you should expect an approximate 30 fps loss in speed.

  • Beginners Guide - Selecting Your Own Recurve Equipment
    Beginners Guide - selecting your own recurve equipment. Original Source: Modified from Anchor Bowmen Archery Club, Borrowash Road, Spondon, Derby DE21 7PH, United Kingdom, modified with permission of the Club. Updated December 2016 Introduction Thank you to Anchor Bowmen Archery Club in the UK for allowing me to modify this document for Australian archers. Most of this document is written from the perspective of the original author and is equally applicable to beginning archers all over the world. Some terms, approximate pricing and local references have been added to reflect our part of the world. Regards, Northern Archers of Sydney Inc. After you complete beginners’ classes you wonder, where to now. When you get to the point of considering purchasing your own equipment you will find the range of options quite daunting at first. This guide is has been created off the back of the experience of recent ‘beginners’ who have been through this process and learned a number of valuable lessons along the way. It is not a definitive guide, but it is hopefully helpful in steering you in an appropriate direction. The best way to use the guide is to read it to get a basic understanding of the considerations and options and then seek the advice of some of the more experienced club members. Many club members will be more than happy to show you their bows and other bits and pieces of kit. Often feel is the deciding factor on what best suits you and there is no substitute to looking at the different options, handling them and getting the opinions of people who use them.

    ?WMRK XLI /RKPMWL PSRKFS[ + VGLIVW HY 1IRIZSMW www.toxophilus.org Security when shooting a bow Archery is a potentially dangerous sport which must only be carried out in an appropriate place reserved for such activity with correct supervision. We decline all responsibility for damage and/or accidents which occur as a result of putting any of the activities described in this tutorial into practice. Shooting line When shooting in a group, it is important that all archers remain behind (or astride in the case of a competition) a visible (or imaginary) line while arrows are being shot. Crossing the line towards the targets during shooting is not only dangerous but is sanctioned by immediate disqualification during competitions. Spectators must, under no circumstances, be allowed to stand between the archer and the target even if they are outside the shooting angle. R etrieving arrows from the target The basic rule is to wait for the last archer to shoot his or her last arrow before advancing to collect one’s own arrows from the target. However, if the order “fast” is given, all archers must immediately stop shooting. The signal that indicates that all is clear to cross the shooting line is when a designated person shouts the order: “Arrows” (or a word such as “score” or “pull”). A rm ing a bow Never arm a bow or even place (nock) the arrow onto the bowstring if the bow is not pointed at the target. All archers must be aware that an arrow can be loosed accidentally before it is correctly aimed.
