March is here!!

Hi readers of this blog!
JD here updating the blog this week!
The month of March is finally here and the quadcopter team was busy writing up our Interim report for our supervisors last week!

Here are the progress of what our team has done this week besides writing up our interim report,

Progress 1: Crash protection cage

Shown above is the crash protection cage concept that has been made by our group mate Bing Zhi. It's concept look like an inverted ice cream with a cone, the one in white it's actually just a stand for it to be able to showcase it to our lecturers.
Even though it is just a rough concept, it can work well on different surfaces!

Like seen above it works on a flat surface and even grass!!

Progress 2: Test thrust rig

For Angus and me we've actually done a few experiments where we took down data on the propellers, motor and the ESC of the system. Basically it's a continuation of what we've trying to achieve since 2 weeks ago.

Like seen on the picture above, we've actually added the tachometer which is used to measure the RPM of the blades, and see how fast it spins.
Another thing that we've added is the multimeter to see how much a motor with an ESC takes the power from the battery. It is certainly surprising that this small motor on it's maximum RPM actually takes around 10 Amp of current with the supply of 11.1 V, which makes it's power consumption to be about 110W!!!

We've actually compared the datas we've calculated with the supposed theoretical calculations of the motor max RPM without the blades.

The datas can be seen on this link
Experiment 25.02.14 data

And the picture above shows me and angus testing the motor with the protection walls and the cool protective glasses that we wear.


There are still a lot more stuffs to be done on our part, and school is getting busier each week, but keep tuning on this channel!! We will update the blog every week and you will see it fly soon!!!!!!!

Take care!!!
