Science Buddies: "Ask an Expert"

The purpose of this experiment is to find out which wing design will create the greatest aerodynamic lift. This topic is interesting because it is testing the performance of different wing designs.

I am not sure how to work this.

Which wing design will create the greatest aerodynamic lift? The independent variables are the wing design, the amount of weight, and the wooden supports. The dependant variable is the aerodynamic lift.

Hypothesis: If the wing design is bent at a thirty degree angle then that will create the greatest aerodynamic lift. The researcher hypothesized this because it seemed like this design is

Materials:

Airfoil
Wooden supports
One speed motor
Weights
This is what I have so far, but I am stuck. How will I test this? I am thinking about using a small, lightweight motorized car and attaching the different wings to it.
Can you give me some pointers? Thank you!

Some thoughts. What you can do is create a single model plane to which you can attach different wing designs to. In the fuselage of the place you can change the amount of weights add on to the plane to see the lift capacity. You will need to keep track of weight distribution when adding weights (you will need to experiment to see what works best but I think placing the weights near the wing will work).

With the link I gave you in your other post, you should add something to regulate the flow of the air (the fan air is very un-even). Here's another link to building a wind tunnel.
