SCREEN SHOTS

And other information...

Screen Shot 1: The Rocket Design Page

On this, the Rocket Design page, you will be able to set many of the initial physical parameters of your rocket, such as the type of bottle being used, the drag coefficient and fluid density of the fuel to be used. Notice on the screen shot that you are able to specify these parameters in a variety of English and Metric units. You'll always have a choice of units for any data in the program.

Screen Shot 2: The Launch Page

This is where you will launch your rocket. Set the initial water volume and pressure, then hit the Launch! button. Watch as the graph plots your rocket's skyward progress. Then, examine other aspects of the flight. Pictured above is the Velocity vs. Time graph during the Thrust phase. You can view height, velocity, acceleration, thrust, pressure or water volume vs time graphs for any of the phases: Water, Air, Thrust (Water + Air), Coast, or All phases. You can also look at, copy or save the raw data from the flight:

Screen Shot 3: View/Save Raw Data:

This data can be imported into Excel or other data analysis programs for further analysis or printing.

Screen Shot 4: The Experiment Page

On the Experiment page, you will be able to run many launches at the touch of a button. Select which variable you want to vary in the experiment (i.e. water volume, pressure, bottle diameter) and then select which flight characteristic you want to watch change (i.e. maximum velocity, total impulse, etc...) So, you could plot the maximum height of a rocket as a function of the initial water volume! Pictured above is Total Height vs. nozzle diameter.
