Has this ever happened to you? You order a package and when it gets delivered you are asleep or away on holiday and someone comes and takes your package from outside your house then when you get home it is gone. When we have a solution to your problem. A drone, you may ask, why a drone?  well, first we are talking about the last mile of the delivery. Well know the real last mile it means from the post office or factory. The person that takes your package to your house or your workplace. this is the most expensive part. So people are coming up with ways to cut costs and CO2 damnation from the vehicles. They came up with drones. So the aim of our studies is to find out what kind of pressure will be the best for a slow descent, accurate landing and a soft landing.

our investigation will study: How the shape and size of the spill hole will affect the acracy and sot ness of the landing? There always constraint and criterion for this type of project. These are some of ours:

    • The velocity of the drop (m/s): Lands with a speed of 1m/s to 2m/s
    • Accuracy of the drop: It must land 50cm within the target.
    • Force when landing: A force of 1 newton? (If we could calculate this)

the variable of my testing is how many spill holes will make the best landing according to my research question. The aim of this study is to find the best shape, size, spill hole, materials and size of the strings. To get the best parachute to drop our package.

We had to do a Drop 0; this was the drop that we tested how much damage would the drop without anything to slow down the speed of the package

The box fell to fast and so it doesn’t meet the criteria because it bounces too far out. According to the data on drop 0 (A) the box fell 75cm away from the centre. this is out of our 50 cm from the middle criteria. On the drop 0 (B) it dropped 100cm from the middle. 2x more than the criteria. Then on the final drop 0 (C), it dropped 50 cm from the middle, Due to the criteria, it was a little too close. as you can see most of the time the box drops too fast it bounces out of the 50 cm radius that we have set up. so, this is a thing that we need to change when we put a parachute to slow the speed so, so this project is about creating a parachute that will slow the speed of a box falling. But I am working on how the shape and size of the spill hole will affect the acracy and sot ness of the landing? I and my team’s criteria are very simple but can put some pressure on how we make this parachute. like the landing force of one newton, how are we supposed to measure this? ` But on the other side having a 50cm from the middle is very use full to the project. The next step to meet the design criteria will be to make the box fall slower.
