Maximum energy storage bow

Do compound bows store the most energy?

Clearly there are many factors, bow design being dominant, but surely this value can be calculated. It appears that compound bows store the most energy, but how much is actually stored? You can draw the bow with force meter, noting the force at set intervals of distance.

How much energy is stored in a bow?

It is more usual and convenient to express the stored energy in foot-pounds rather than inch-pounds, so we divide by 12 to convert: 518.72 in.-lbs. / 12 = 43.23 ft.-lbs. (Result is rounded to two decimal places.) Thus, when the bow is drawn to 28 inches it has stored 43.23 ft.-lbs. of energy. We will call this value stored energy (Es).

How much energy does a recurve bow store?

Thus, when the bow is drawn to 28 inches it has stored 43.23 ft.-lbs. of energy. We will call this value stored energy (Es). Since this is a conventional recurve bow, not a compound, the highest draw force obtained (peak draw force) was measured at the highest draw length (28 inches).

What is the kinetic energy of a bow?

While the kinetic energy of the arrow is an interesting value in itself, the principal use is in the computation of overall efficiency of the bow. The overall efficiency of the bow is defined as the ratio of the kinetic energy of the arrow as it leaves the bow to the energy used to draw the bow, expressed as a percentage.

What are the characteristics of a bow?

The second, and probably the most important, characteristic we want to evaluate in a bow is shooting performance. A bow can store energy quite efficiently and yet not deliver an arrow very well. Not all of the energy stored in thee drawn bow is imparted to the arrow when the shot is made.

How do you calculate the launching efficiency of a bow?

Calculate the draw :Calculate the velocity, v, of the arrow at every midpo each bow te the launching efficiency of the bow and arrow system, ξ = ( mv 2f /2 ) /W for(iv)(v)each bow.Interpolate v2 /2 as a function of the arrowhead position x ith 5th order polynomial, and take a derivative to get the acceleration as a function culate th
