Hello people!
This is Dimitris from Greece. The device described in the title, annoys me as a recurring dream for a couple weeks now.
Therefore I turn to you for a cure!
What power would a very slow biplane require to sustain level flight ? (single seat)
CALCULATIONS:
The glider + pilot = 120 kg weight ( = 264 lbs)
Wing area of 20 m2 ( = 215 sq feet)
Wing loading = 6 kg / m2 (similar than a hang-glider)
Now if we lay this area with PV (photovoltaic cells), we can get power of about 150 Watt * 20 m2 = 3000 Watts.
Also, with the addition of a small battery, we could utilize a more powerful motor (say 5000 Watts) for limited time.
(e.g. for takeoff needs). But we can not count on such power on the long run. The average must be 3000 Watts.
Are 3000 Watts enough ? Or some other suggestion ? I am interested in a relaxing slow flyer, not the sailplane low-drag
type, which has already been done years ago.
Thanks for reading, waiting for your reply, thanks
