[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.

  • 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.

Airplane modelling

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.

Rocket Modeling

  • 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.

Rocket Activities

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.

3D Water Rocket Simulator

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. *

  • + 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

To Do

  • 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.
