[My Pimp Mobile] Aerodynamics of an object:in try of reducing air drag with simulating different versions and simulations of a virtual object in air tunnel; improving it's aerodynamics - in purpose of enabling faster traveling but again trying to keep it safe. Air tunnel simulation basically - how would an object react depending on the material used and its shape/structure? How much does air affect its possible movement? And the direction of the 'blowing' and the movement of the object affects the simulation result. The idea started watching F1 'cars' - which try to use lighter materials so the weight doesn't affect speed, but also to improve very crucial factor - the aerodynamics of the vehicle. Must point out that this model would be based on the physics principles-so its that is the science side of it.
- http://en.wikipedia.org/wiki/Aerodynamics - Wikipedia tells it all about the aerodynamics, one should know. Some ideas about modeling could be obtained.
- http://en.wikipedia.org/wiki/Wind_tunnel - At the lower part of the site - it talks about visualizing the results and the whole simulation of the wind tunnel. Interesting.
- http://www.archiseek.com/content/showthread.php?t=5481 - This link provides multiple links (e.g. http://www.ansys.com/products/cfx.asp Ansys - fluid dynamics) of the software which might be used for modeling such situations described. -It is not freeware, but could be perhaps achieved for education purposes.
- I found another link - which contains some free and simple simulators of some stuff related to airplane modeling - its from NASA and it contains some guides also.
- I have downloaded 3 software's out of the all offered - they're the simulators of different flying situations; from the engine throttle to the air flow around the wing. Might be helpful. Those are:
**EngineSim **EngineSimr **FoilSim
When the files are downloaded; after unpacking them, they contain Java based simulations, which we open in our browser.
** "Make your own Wind Tunnel" I went through interesting links - depending on what we want to achieve this might help. http://sln.fi.edu/flights/first/makesimple/index.html
A Link for freeware program (115 MB size) called Alice, which creates airplane models and simulates flights. Also contains guide to create a airplane in 1 hour.
- Also the website from the link, contains some guides into modeling a real life paper plane; in terms of how to make it fly like a real one(folding techniques and similar).
A link that contains further info about Alice - also contains a Video which gives closer look at the software. From first sentence: " Alice is an innovative 3D programming environment that makes it easy to create an animation for telling a story, playing an interactive game, or a video to share on the web. Alice is a freely available teaching tool designed to be a student's first exposure to object-oriented programming. " And so on..

I explored Alice and made the simulation. Possible variations.
Contains simulator links ; explored Google Earth one - still thinking about the whole purpose - but I guess its upcoming. Pretty fine and detailed one. Ready to present.
- http://orbit.medphys.ucl.ac.uk/orbit.html A space flight simulator;could be of some help. Didn't explore it yet.
- Rocket Modeler II
- Rocket Thrust Simulator
- Atmospheric Effects Simulator
The 3 basic simulators of the rocket flight - a rocket model. Besides computer simulation, there could be guides followed up to manufacture a real life water rocket (e.g.) which could fly around; possible lab.
Some of the classroom rocket activities are described on that site;following the links posted there could lead to further guides. It includes the above mentioned Water Rocket, comparing real rockets with the ones we create, and similar experiments.
- Constructing launcher for water rocket:

3D Water Rocket Simulator http://www.grc.nasa.gov/WWW/K-12/rocket/BottleRocket/Install_sim.htm
Free download - possibly very useful(will look into it). - *Update on 3D simulator: Still under development - the link above is for Java 2 and Java 3D download. Could be available at the time we need it, so I will keep the link around.
- Educator section - worth reading.
- I have downloaded this really interesting water rocket simulator - which on first sight gives allot of probably useful information. * http://www.seeds2lrn.com/rocketSoftware.html
- + Edit: The site also contains bunch of information about the water rockets. Very good and detailed.
Ready to present it.
- Second revisit : The site also contains the link the .pdf file; the rocket lab - which I find awesome - free of charge: we can actually use it or make our own out of it. It is download-able at this link:

- Interesting and hits physics, area we want to include
- Computational fluid dynamics
- Very clearly modeling - trying to see how something will behave on a track or something
- Might be difficult to simulate a wind tunnel
- Potentially model paper airplanes
- Can build anything they want, very hands on engineering
- Potentially build car models (little cars)
- Real life application: Pringles chips
- Check out Nasa's Rocket Modeler. They could simulate the rocket in software and then try to replicate the results outside with a real rocket.
- Make sure there's something we can bring it back to the real world, too, with whatever direction we end up going with this.
- Look at what you can find for a model airplane simulation: slightly easier if we're just using paper airplanes.
- Narrow it down to a few possibilities to go forward with.
- Set up Alice and try the software. Also try making the paper airplane, and bring both of those in to show us.
- Also keep looking forward into rockets. The water-based one is probably our best bet and/or the other one without solid fuel.
