The following features are planned for the future:
An exterior ballistics calculator to estimate range and precision.
Uncertainty quantification. (For example, could be used to find standard deviation of muzzle velocity or precision.)
Design optimization including constraints.
A pressure gradient model to improve accuracy for long barrels.
A transonic correction model to account for potential shock waves in front of the projectile.
Humidity as a factor.
Propellant gases other than dry air for pneumatics.
BlasterSim model features are taking priority to this at the moment, however, the following are planned once the model is feature-complete:
A graphical user interface for computers.
A web-based interface for informal use and use on mobile devices.
