The optimisations continue and they spit out
Rotor radius 2.22m
Blade length 1.4m
TRPT radius 0.5m
TRPT section lengths 1.25m
Elevation angle 18.5
TRPT total length 190m
Tip speed ratio 3.5
This results in an operating altitude of 60m, far beyond the operating height of a HAWT with a power
output of a few kW.
