CO2 Dragster Design

Overview

Students will use WhiteBox Learning to design their dragsters. The program is web-based, so it can be accessed anywhere with an internet connection. Students will follow the engineering design process to create the fastest dragster possible while meeting the given specifications. First students will conduct research that will allow them to make a better design. Next they will design their car. Whether or not the car meets the specifications can be checked at any point during the design phase. Once the car is meets the specifications, it can be tested in a virtual race. All four middle schools in Frederick County can race against each other. Once the car has been raced, students can go back and make revisions. This process is repeated until the optimal design has been reached. After the class has completed the design phase, technical drawings will be printed and the class will move to the production lab to make the cars and test them. Cars are raced along a 66 foot track. Depending on the weight limit for the year (which comes from TSA specifications), the cars can run over 60 mph! WhiteBox Learning Link

Resources are available for students starting the project or having difficulties getting cars in spec under "Tutorials".

Dragster Wheel & Axle Calculator

Visit this link for a program that will calculate your best wheel type, axle material, and length to cut each axle. Calculations are based on the options we stock in class (LX/PX/Nitro wheels and aluminum/steel axles) and it is set for laminated tube bearings. Click "Run" at the top of the screen and fill in the requested information and the program will do the rest.
