I have been trying to get this design out of my mind and onto paper for some time and have finally managed to get my head around Google Sketchup to make it reality over the weekend.
I have been looking for a frame that is:
1. Light weight
2. Protects the blades
3. Provides enough space for accesories within the frame.
4. Has a flat unibody design.
5. Will become a universal "air platform" with enough space on top.
6. Has a future being stacked for added lift.
Feel free explore to explore sketchup model provided! I wil be detailing the model further before moving to production.
While I'm not sure how much use stacking is beyond a certain level (manoeuvrability would be impacted, surely?, what would you make it out of that's strong enough to prevent damage, light enough to not add excessive weight, and cheaper than merely replacing blades occasionally?
Also, you may as well complete the casing around the propellor and make them into a ducted fan for more lift, I would've thought? Assuming you can get a tight enough fit.
Hi. You are not alone with such a design. I personally do not like the appearence of popular crossbar q-copter frames. Having the benefits in minimal weight, it looks far from what i would like to end up with. So i came up to something similar to your spatial frame. I cnc'd two layers of thin plywood to see what it will look like IRL and connected with foamed PVC rings to have some king of impellers. The height is too much however.
For the final frame i'm going to use an aluminium composite panel as i have a lot of il lying around, but i suspect it would be nice to make it out of carbon or fiberglass sheet. Can't tell anything about the weight yet. Will keep you informated as far as the progress will go.
very cool idea!! keep on keepin on!!
indeed, keep going
you know you could always 3d print the plates and reinforce with CF rod to see how it responds. I personally really like this design and would be interested in flying it myself providing it flies true. I would suggest that if you are planning on doing this frame as a for profit, that you remove the technical diagrams or else one of the other manufacturers can beat you to the punch using your own diagrams and designs for their machines. Or are you planning on giving open licence.
I tell ya what I would really like to see in a quad, A servo hole to mount a pan tilt bracket but one could always cut their own.
Hmmmm now ya got me thinking that I could just use my prop rings to be the frame all together. Stick a X of square stock for rigidity and motor mounting.
