Managed to run a mast mount 6 blade ring rotor test today.
Ran well for just over 10 mins before I was careless with braking and crushed the shaft.
Kinda lucky I did, there was a powercut here just after and data which was saved just in time would otherwise have been lost.
The data will be run through thoroughly by @Ollie before publishing.
Control algorithm ramped up the current really well. Chuffed with that…
Just wish I’d used it better for slowing the rotor down…doh.
The ring took a crash spectacularly well (all blades and fuselages fine after ground strike at ~85+rpm) as I had left the fuselages loos-ish on the ring.
Highlights of the data were… Peak power 624W at peak rpm 146 @~7.5m/s 8m/s
Looks like it had 100kg line pull …although the mechanism that sensor is on …don’t trust it… bodgy.
The really exciting thing today was the use of GOLD Duck Tape
Aye Aye POSH
And if you see the video…yes I should have had a helmet. A mini mohawk hairdo, although it looks hardy, isn’t going to be enough in a worst case.
Fun day out (in lockdown on the croft)
