Why Kites...
- Thread starter Thumper2
- Start date
Hey Winnie.If Your really bored try driving down the road really fast and sticking your hand out the window.You can vary the angle of attack or is that the angle of incidence and with varing the speed you can see what happens.Just like your kite or airplane wings.If your s300 is fast enough you could try sticking your hand out the window of that as well

But there is only one thing, the kite is not nose down, it is nose up, thus shouln''t the lift vector point up and back, not up and forward? Anyways, seems like people woke up, to answer, even though the others were about RDM''s new car.
But the string is only a minor part isn''t it, and I also noted that if you pull ont hte string, that also make it accelerate, suppose that has to do with lift/weigh/load factor as well.
Guess I was trying to think too hard about it!
Well, one thing is for sure, my kite won''t even make it to 200 feet above the aerodrome, but it sure is fun!!
407D:
They won''t even let me look at the MEK bottle, let alone sniff it!

I though everybody down in YYT drove minivans, not cars, atleast that is what it seemed like when I visited in my Giant Scweizer a few weeks ago
RDM, I guess we have a test coming up in wekk and a half, as the maintenance will only take 3-4 days, and goes in on monday morning. Will give you a call today or tomorrow.

It works as a wing. The result forces are: One exactly opposed to the direction of the string and another is along the longitudinal axis of the Kite. The lift is the combined result force.

RDM is driving a new car you say ....oh my gad, here we go again...A1 Towing, 772-3425....Nfld. Constabulary, 772-8976......ambulance 772-4445. It''s no bloody wonder Insurance rates are so high in Atlantic Canada!!

Has everyone forgotten about the center of pressure? RP is right that the lift increases, but it must be designed so that, with the increase in lift, the CofP moves forward, imparting a forward vector to the line of lift, thus accelerating the kite forward, nu?

When the wind speed increases, the kite produces more lift like a wing. It can''t go further away from you, it is held by a string, so it accelerates up along the arc of the string until the force vectors all balance again. Going up on the strings arc decreases the angle of attack, but the higher wind speed leaves the total lift about the same. The kite is just trying to keep its force vectors even. (lift, drag, g, thrust)
