What is a crash test dummy ?

A crash test dummy is a life-size model of a human being made to act as much as possible like human in a state of crash. Although people think of car crash when they hear the term, it is also used as an important tool in aircrafts and other vehicle to know how safe they are. It can experience snapped neck, broken limbs and other traumas that might happen to a real person in a crash situation.

As soon as automobiles are invented, it started injuring people; so automakers realized that they need to create some safety features on their cars, which includes testing their vehicles before making it available to the public. Other vehicle manufacturers for boats and aircrafts also realized the importance of crash testing.

The early crash-testing tool used is cadavers; it is a reasonable replacement for a living person however, the use of it fills ethical issues. In addition, they are not uniform, which means, test conducted with cadavers are not repeatable and scientific. Then, researchers started using live animals but issues regarding uniformity occur, leading to the invention of crash test dummies.

Sierra Sam was the first crash test dummy ever created. He was made for aircraft ejection test in 1949. After Sierra Sam, many versions of dummies were created. Now, they come in families, which give researchers chance to check on the safety of men, women, children and even infants.
