The ballistic pendulum was invented in 1742 by English mathematician Benjamin Robins (1707–1751), and published in his book New Principles of Gunnery, which revolutionized the science of ballistics, as it provided the first way to accurately measure the velocity of a bullet.
A ballistic chronograph or gun chronograph is a measuring instrument used to measure the velocity of a projectile in flight, typically fired from a gun or other firearm. The instrument is often useful for tasks such as gauging the utility of a firearm or safety of non-lethal projectiles fired from items such as a paintball gun or BB gun .
The ballistic pendulum was invented in 1742 by English mathematician Benjamin Robins, and published in his book New Principles of Gunnery, which revolutionized the science of ballistics, as it provided the first way to accurately measure the velocity of a bullet. [7] [8] Robins used the ballistic pendulum to measure projectile velocity in two ways.
Benjamin Robins was born in Bath. [1] His parents were Quakers in poor circumstances, and as a result, he received very little formal education. [1] Having come to London on the advice of Dr. Henry Pemberton (1694–1771), who had recognised Robins's talents, [1] for a time he maintained himself by teaching mathematics, but soon devoted himself to engineering and the study of fortification.
In 1742, Benjamin Robins invented the ballistic pendulum. This was a simple mechanical device that could measure a projectile's velocity. Robins reported muzzle velocities ranging from 1,400 ft/s (427 m/s) to 1,700 ft/s (518 m/s).
External ballistics is the part of the science of ballistics that deals with the behaviour of a non-powered projectile in flight. External ballistics is frequently associated with firearms , and deals with the unpowered free-flight phase of the bullet after it exits the gun barrel and before it hits the target, so it lies between transitional ...
And then to properly design recoil buffering systems to safely dissipate that momentum and energy. To confirm analytical calculations and estimates, once a prototype gun is manufactured, the projectile and gun recoil energy and momentum can be directly measured using a ballistic pendulum and ballistic chronograph.
However, subsequent work on ballistic pendulums by Benjamin Robins (1707–1751), a British mathematician and engineer, suggests that he independently repeated many of the same results. [4] Regardless of the extent of Cassini's original contributions, his work on the ballistic pendulum was significant in its time and helped to advance the field ...
