recurve and bow
A recurve crossbow is a bow that has tips curving away from the archer.
The recurve bow's bent limbs have a longer draw length than an equivalent straight-limbed bow, giving more acceleration to the projectile and less hand shock.
Multiple bow systems have a special system of pulling the sinew via several bows ( which can be recurve bows ).
The limbs of a compound bow are much stiffer than those of a recurve bow or longbow.
This effectively makes the bow function very similar to a recurve, with the draw length determined by the shooter's preferred anchor point, but it also removes the necessity to adjust the draw length or purchase a new bow as the shooter grows up.
A traditional recurve bow has a very linear draw weight curve-meaning that as the bow is drawn back, the draw force becomes increasingly heavier with each inch of draw ( and most difficult at full draw ).
This manipulation of the peak weight throughout the draw ( accomplished by the elliptical shape of the cams that change leverage and mechanical advantage ) is why compound bows store more energy and shoot faster than an equivalent peak weight recurve bow or longbow.
* When a compound bow is drawn, the limbs are pulled in toward each other, by the buss cables, unlike a longbow or recurve where the limbs flex in the direction of the bow string.
* Unlike most recurve bows, replacing the string or making adjustments to let-off or draw length often requires a bow press or a trip to an archery pro shop that has one.
* The relatively low holding weight of a compound bow compared to a recurve bow makes the compound more sensitive to certain shooting form faults when the archer is at full draw.
The only notable difference is that the spine of the arrow, which is a measure of its stiffness, is not as great for a compound bow as it would be for a recurve bow of the same draw weight ( power ).
This is due to the fact that a compound bow will accelerate an arrow more gently and linearly as the cam unwinds so flexing the arrow less, as compared to the explosive acceleration of an arrow from a recurve bow where the full power of the limbs is applied to the arrow as soon as the string is released.
Both the Huns ' and Magyars ' historically attested skill with the recurve bow and arrow are attributed to Nimród.
However, as the bow is drawn, the recurve ' unwinds ', the limb becomes effectively longer, and the mechanical advantage of the archer increases.
A recurve bow has tips that curve away from the archer when the bow is strung.
By definition, the difference between recurve and other bows is that the string touches a section of the limb when the bow is strung.
