Ballistic Calculations
We developed a mathematical model of bullet flight in air. This model outperforms leading ballistic calculators in the field. Currently we implemented an iOS and Android calculators using this novel model, we also have an implementation working on ARM Cortex M4+ and Cortex M7 microcontrollers, as well as a version for web pages. An FPGA implementation of this model is currently in development.
We use sophisticated statistical analysis of actual shooting data to build custom aerodynamic profiles for specific bullets from leading manufacturers. We also use a custom atmospheric model to predict air density in different weather conditions.
In the picture you can see the air drag coefficient values calculated for .30 caliber Lapua Scenar bullet in 155gr. Shooting data derived profile is closer to the Doppler radar data than either standard G7 or G1 ballistic profiles. In fact, default G1 profile suggested by the manufacturer is completely inadequate for accurate predictions. Shooting data derived profiles provide better prediction accuracy when Doppler radar data are not available. Range of velocities between Mach 1 and Mach 3 is the most critical for long range shooting.
Our model accounts for wind deflection of the bullets, gyroscopic drift and Magnus forces.
We intentionally discount Coriolis forces, as they do not have a significant effect on small arms projectiles. However, if any of our clients desire to model artillery fire, we can easily modify our models.
At the moment we provide our expertise in modelling ballistic performance of small arms bullets as a service to commercial product manufacturers. Our model is currently employed in ballistic scopes and rangefinders offered by two big scope brands.
We will be happy to consider your requirements for ballistic predictions, and come up with a solution that can be easily integrated in your product line. Please, drop up an email at developer@nuwaste.com
