WARPS - Water Rocket Prediction Software
Version 1.0.0 - December 11, 2002
WARPS is a program which calculates almost every aspect of your water rocket and of it's flight. Since in the field of predicting a flight of a rocket there are too many variables to be calculated, there is a clear need to use a computer program to perform those calculations.
There are other water rocket simulators (look on the links page) but I wrote this one because not only there seems to be a lack of a really good computer programs. Except WARPS, there's just one really good that I am aware of and it's written by Paul Grosse and can be found here.
For other people wanting to write a simulator, I have compiled the equations I used for calculating the thrust phase performance and the flight by itself here.
Also, if you want a practical example of the implementation of those equations in a computer program, I wrote a simple console program for calculating just the thrust phase and I released it together with the source code (QuickBasic) here.
Current features:
Currently, it's main features are:
- Calculates all three phases of the flight
- Parachute support
- Rocket CP calculation based on Barrowman equations
- Angled flight support
- Downrange calculation
- Plots flight and engine data
- Air impulse calculation based on Bruce Berggren formula
- Flight optimizer. Optimizes the rocket parameters for maximum performance
- And many others
Known issues
- Doesn't has support for launch tube, or two stage rocket. Will be added in the upcoming releases.
Disclaimer
WARPS is freeware. It means you can distribute it freely as long as don't charge anyone for that.
