Parametrization the flight trajectory of blood drops in an experimental model with the use of a firearm
2017
Abstract
Blood marks analysis is a common technique used in forensics. However, current methods used have their limitations and deviations.
The most commonly used trigonometric model is based on the linear movement of a blood drop, which disregards air resistance and gravitational force which affects all mass points in an area of space. Specific physical characteristics of a blood drop after its separation from a larger blood formation determine its spherical shape and typical patterns after impact.
The main goal of this paper is to map the flight trajectory of blood drops in an experimental model with the use of a firearm. These trajectories will be compared with mathematically definable functions and a mutual relation will be established.
