This is version one of my Trajectory calculator. Here I was playing with some functions to calculate values such as the horizontal range, the apex, as well as others. Simple, lightning fast and elegant are the features version one has, but it is fairly visually poor. Below you can see how i added graphinf capabilities which on the fly calculate and plot the arc of the trajectory. Keep in mind that in the first and second version of this program, the air resistance and drag due to wind is negligable and therefore, unaccounted for. In Wind Plot (see below), however, i do take these factors into account.

The calculations in this demo are unchanged, but it provides a visually stimulating real-time plotting system. You can plot many graphs on a single chart, or you can clear and plot new coordinates. The relatively simple theta velocity calculations allow for fast and correct calculations scaled to the Twip. For more information, contact me.

This is a screenshot of another new program which gives you the capability to plot the path of a ballistic object under the effects of both its own wind, and external wind. The wind settings are variable in this program. You have the ability to change the speed at which the wind blows, in meters per second, as well as the angle in which it blows. I was unable to find a set series of equation for the plotting so until I do, i will be using formulas that i wrote to calculate winds effect on the missile. So far, testing of this program has concluded that, minus air friction and atmosphereic friction as well as pressure induced friction, this program is accurate enough to calculate any number of 2 dimensional scenarios. Furthermore, this program allows graphing of both a situation where wind is a facotr, and a situation where wind stress on the missile is negligable. All this together allows for accurate and detailed analysis of ballistics.

Another custom option for this program is the new Plot lines. The plot lines allow you to see the plot with some sure accuracy. You can accurately measure the approximate distance without having to use your fingers as a guide. The scaling is setup in an intuitive manner so as to take the guess work out of plotting. The Vertical and Horizontal plot lines are placed precisely 500 twips from eachother, each twip representing an entire meter. Thus, you can quick and easily count the effects of wind.

A new version released with the all new directional indicator. This little meter will draw a tiny image pointing in the degree of both the wind as well as the launch angle. Very handy for seeing if the plot will graph at all. Hope this is useful. New ideas and updates are coming soon, so check in often.
