The following features are planned for the future:
A spring calculator to estimate spring stiffness and mass.
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. Whether this would help accuracy would need to be determined first. In a normal gun, the gas velocity at the breech is zero, creating a significant pressure gradient, but that’s not true in the compressed gas guns BlasterSim models. The differences in velocity between the projectile and breech may be too small for the pressure gradient to matter except in particularly long barrels. The gas velocity will be zero at the end of a pressure chamber, however, and that may make the pressure gradient model important for longer pressure chambers.
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.
