Project collision part 4:

Currently, my team and I are trying to make the parachute prototypes, but due to the coronavirus outbreak, school got canceled, causing a lot of difficulties for us. Even though coronavirus is causing us trouble, we, Techincal, will still design and make a parachute that will allow our package to land softly and accurately, and my job is to design and make the best suitable size of the parachute to secure a slow, soft landing. Due to coronavirus, we now have limited materials and also need to create a different texting platform that we can access from home.

Testing procedures:

The image above shows our testing procedures from FA space, but currently, we cannot access that space, so we might have to collect data differently at home.

Data table:

Unlike the procedures, our data table will stay the same.

Prototype 1:

1x plastic parachute canopy

8x red strings

1x spill hole

1x green paper box

Due to a lack of resources, this design is different from our initial design. The box is in different sizes and is lighter than the original box, because of this, the parachute was also made to be smaller. For strings, the material and length of each string is different from the initial design, but the number of strings stays the same.

Project Collision

Have you ever wondered why the package you order still hasn’t arrived? Or why you need to pay shipping and delivery fees? Well, it turns out that your package goes through a lot of processes before it can arrive at your front door, which not only takes a long time, but it also uses up a lot of resources, causing the shipping fee to cost a lot of money. But nowadays, company like zipline or flirty is trying to make this process easier, cheaper and faster with the help of drones, these company is planning to drop the package from the drone at around 8 to 10 meters above ground, and our goal of is to make sure the package delivered from the drone will land safely.

One way to make sure the package can land softly and accurately is to make a parachute, which is what my team and I are trying to design. My job is to find the best suitable size of the parachute to secure a slow, soft landing. And to achieve that goal, I need to decrease the speed of the fall. But to understand this, we first need to talk about how a parachute works. Parachutes can be commonly found in the sports of skydiving; when a person jumps out of a plane at a high altitude and starts falling at high speeds because of gravity. Then, the skydiver would open a parachute that would help the skydiver slow his or her way down and break the fall, allowing him or her to land softly and safely. But what is the parachute doing to stop slow the fall down? The parachute slows the fall by catching air and creating air resistance with its surface area to counteract gravity, this is also known as drag. This means that the larger the parachute, the greater the drag force (according to Scientific America).

But before we start designing our parachute, we tested our box without any design to collect data so we can compare it to our future design. That way, we can tell if the design is effective. These are some of the data we collected on the first drop:

Average speed 2.991725m/s

Slowest speed 0 m/s

Fastest speed 9.5702969m/s

Accuracy of landing 25cm off-target

Accuracy of its final destination 1m off-target

The side it landed on Topside

The side where that it ended up with Right side

With the data we collected, we can now see what we need to improve on. One of my most important goals is to decrees the speed of the fall to at least 2 m/s, or the impact will destroy the package.

Our goal is to protect our package from an 8-meter fall, and my key question is what the perfect size of the parachute is to decrees the package of the speed and reduce the impact before the package hits the ground. And my next step is to design and make the perfect sized parachute.

Story blurb

Dr. Liam and his team are on the hunt for the cure of a new disease which spreads rapidly and damages the human population. Dr. Liam is the last hope of humanity. Will he be able to find the cure?

Flood and disease

Math:

On this exit ticket, we were tested on two simple math equations that we learned a couple mouth ago, I think it was very easy. On the backside of the exit ticket, we were asked to rate our selves on collaboration, I gave my self a 4 out of 5 stars because I think we did a very good job on making the blueprint of our house design. I didn’t give myself 5 stars because we were s bit behind compared to other groups.

Science:

In science class, we were tested about photosynthesis, I think it is very easy because I already learned this topic in my old school. For the backside, I was asked about what I struggled with. I think I struggled with drawing a tree because I wasted too much time on it. Plus, it wasn’t even that important.

Humanities:

In exit ticket for humanities, I was asked to rate my self as a collaborator (again) for our book club, I gave me and my group a pretty good rating because we were constantly asking each other questions and kept the conversation alive. I didn’t give our group the best rating because sometimes, we would argue on some parts of the story.
