G'day all
I'm about to kick off a concerted design effort for a ~5m 'perpetual' electric glider. There's a few of these getting around but in a nutshell, charge the batteries from PVs all over the 'top' during daylight, then run off the accumulated charge overnight - do it all over again for a long as the weather allows. I'll go into more depth as the ideas condense into thoughts but for the moment, I aiming for a big, slow monster
So... I need a nice, high lift, thick (low RE), slow speed (cruise around 15km/h) airfoil. There is a staggering array of options! I'd very much appreciate any thoughts, suggestions and input on selection criteria. Currently thinking something along the lines of a Rhode St Genese 34 or maybe the remarkably similar GOE 398?
I accept that I might not achieve perfection first time around But before I actually start cutting I thought I'd solicit the sage council of the hive mind
I'll probably end up building a few test wing spans (~1m) to test construction ideas and evaluate rigidity. Torsion and weight will be the enemies!
Current idea is that I'll be getting a flight controller (Cube-esque) to do most of the automated flying. This should allow me to follow the current thinking of 'let the software worry about the stability etc'. Yes, I'm sure a lot of you are shuddering at the thought However, from that I can (potentially) build the monster wing without any dihedral.
Cheers
