Parachute Investgation

presented by: Hailey, Leah, and Megan

Engineering Design Process!

For the first step we defined the problem (shone above). In the second step researched the problem using links that Mrs. Stafslien sent us. Next we brainstormed the possible solutions, we drew possible ideas for the final parachute. After that we chose the best design for our parachute. Then we built our deign. For this step we tested the parachute. Finally we are demonstrating the commutation piece.

The Problem!

We needed to come up with a solution to the parachute malfunction that the Red Cross was experiences.

Averages.

Drop height in meters- 2 meters

Drop time in seconds- 1.87 seconds

Velocity- 1.09

Distance landed from target in centimeters- 25.75 centimeters

Materials that we would of wanted!

We would of asked for a better, more durable material for the canopy so are rate of decent would be slower.

Did we succeed?

The answer, no, for the most part. We don't think we succeeded because we kept on having to redesign using the same materials, which caused us to loose things and it also caused us to create holes in the canopy, this caused the parachute to land far from the target and making our rate of decent pretty fast.

Do engineers have to adapt?

Yes engineers have to adapt to their original plans because certain things fail and others succeed.

If we had to do it over again!

If we had to do it over again form the original design we would pay more attention to our measurements, make the vent a little smaller, and try to use less materials to hold the fright, if any at all.

Did we redesign?

Of course!!!! We redesigned multiple times. We also asked for and receive extra materials after we had our first design but we didn't end up using it for the final product. We decided to redesign for two reasons. First we did it to try and improve it but that failed (and created holes in the canopy) , second our first parachute didn't meet the criteria. Finally no we didn't have to negotiate with other groups.
