WHAT IF: You put a heli on a turntable and it kept the same speed as the rotor blades but in the opposite direction would still be able to take off ?

What if the table turned in the same direction ?

If the turntable moved at the same RPM, but opposite direction, the blades would have zero speed through the air, therefore no lift.

If the turntable spun the same speed and direction, then you would not need to power the heli, but you would need to be very good at controlling the heli in a 2000 RPM pirouette. Wait, if it's strapped to the turntable it couldn't lift off. If it wasn't strapped down to the turntable, as soon as it started to lift off it would lose power. Wait.... My head hurts.

Morog, you've gotta cut Blade_Master1 a break. At this time of year Canadians tend to go a little crazy -- cabin fever I think. And people wonder why I moved from the Ottawa valley to Florida.

No, I'm not retired. Why do you ask?

Thanks WAFlowers
Yes we go nuts in the winter, Can't fly heli's much in the snow when it's -15 C

(as violins play in background)
My Heli's are also sad and lonely, they just want to fly
I caught one of them trying to sneak out late at night but then he noticed his blades weren't on

I left our dog -- a toy poodle (muscular guy, not one of those wimpy furballs) -- out in -30C once for a few hours. I let him out, got busy and he never barked to come in.

When I remembered I was expecting to see a pupscicle. Instead when I called he dug himself out of a snowdrift on the back deck.

At this time of year I used to get into heated discussions on the best way to cross thin ice (move fast or slow and cautious) and other great Canadian philosophical debates.
