Lift and Drag Measurement: Post 2

Fellow Basement Scientists,

The last installment brought about the development of the lift and draft measurement mechanism. However, we still needed to build the device hold it.

Before designing our anchor contraption, we must understand all of what it is meant to do. It must let the anchor screw rotate but not move, and anchor the springs while allowing their length to be adjusted. The first is easy, just drill a hole and stick the screw through it. The second is more difficult. My idea was to have instead of a hold, a slot. The spring would then be attached to a long screw which could more back and forth through the slot and tightened in place. Ok, lets build it.

On to the Next!

In order to conduct science you need measurements. For our Wind Tunnel tests investigating fluid mechanics and aeronautics we need to measure lift and drag. There are a lot of ways to measure lift and drag, but with all basement science we need to ask, “What’s available?” As usual, my what’s available is wood. This time I have a box of old balsa hobby wood. This wood was my grandfathers and was used to make little glider airplanes.

When the Going Gets Tough

Dear Fellow Basement Scientists,
Having built our wind tunnel and realized that construction takes a lot of patience, time, and effort, do not be discouraged! Completing meaningful work is often difficult and at times frustrating. When you reach this point you must ask yourself, “Why in the world am I doing this?!”

Project: Wind Tunnel

One night laying in bed, I often can’t fall asleep because I am thinking about mechanical things, I was thinking about wing designs. Many PhDs, professors, and companies are trying to think of innovative aircraft design for increased performance. I had some interesting ideas which I had never seen before and wondered if they had any merit.  I decided I wanted to throw my hat in the ring. The only way to determine if they are any good is simulations in a computer program or a wind tunnel, for me then, wind tunnel it is.
