hi!
so i did tests
and my discoveries are sad
1. pure turbine has to be placed in some kind of tunnel but not exactly
funnel
the tunnel has to be as a part of ball (sphere) without hats :)) at the
upper and the lower side
because the stream of air has to compact and air cannot escape near the
blade of rotor or turbine
2. lego motor http://peeron.com/inv/parts/2838c01 is the only one useful
because the new motor has no enough speed
3. propeler has to be non-lego beacause of weight and shape and stability
4. turbine can be weighty so motor can rotate it and keep the speed
(flywheel)
5. good turbine is cd-disc :)) cut on chords and bent termicaly (it's heavy
enough) (you need some tools to do it)
6. for me it's impossible to do lego frame light enough (in fact lego parts
are heavy especialy axles)
7. making skirt is very important (i did it from plastic bag) it's a little
bit hard to do it
so this is 7 sad observations
now i'm not really suprised to hear taht even small planes has very big and
powerfull engines
(those ones which haven't big engine have big wings)
but i'll keep trying
and i hope all of you guys too
