Generate Quadcopter Frame Ultra - 7,73g

Last crawled date: 1 year, 10 months ago

This is my third entry to The Generate Quadcopter Challenge ( https://grabcad.com/challenges/the-generate-quadcopter-challenge ).

Max. mass reduction of the frame - 7,73g (the greater weight reduction - simualtion failed).

To optimize the shape of the frame i assumed the following:
1. Forces:
- Elecrtonics 42g = 0,41202N
- Motor thrust 120g = 1,1772N (per motor)
- Wires 25g = 0,24525N
- Battery 47g = 0,46107N
- Payload 250g = 2,4525N
- Motors 26g = 0,25506N

In this entry (as in the second entry) I divided wires weight between electronics and motors (two parts to electronics and one to motors).
- 0,24525N/3 = 0,08175N

And the forces i used in this simulation was:

- Electronics (with 4 pcs. Speed Controlers) = 0,41202N + 2x0,08175N = 0.57552N
- Motors (4 pcs.) = 0,25506N + 0,08175N = 0,33681N
- Motor thrust = 1,1772N (per motor)
- Battery = 0,46107N
- Payload = 2,4525N

2. Stand - no payload (250g) and without thrust. On the surface of thrust i had to accept the minimum foce (0,01N), because when i put a zero (0N) simulation failed.
3. Fly1 - surfaces of payload mounting - fixed - the wieght of components and the full thrust (it's more than just a payload)
4. Fly2 - area of the thrust - fixed (only the wieght of the components)

I've decided to do two load cases of fly because none separately does not reflect well the reality.

Mounting electronics, battery, payload with adhesive-backed Velcro. Using zip ties is also possible.

And once more: great software, a lot of new experience with shape optimizing and great fun!

Thanks Frustum!
