We get this in every high wind thread. Risk adverse guys who stop kiting above a certain wind speed cant fathom others kiting in wind speeds they cant. Toby is the ring leader advocating not kiting in high winds. Then he takes a 18m kite and kites in a jam packed lagoon in 25 knots providing more risk to himself and others than I guy kiting in high wind with on an isolated beach with the right equipment.
This is the only realistic post in the entire thread. People desire to maximize adrenaline factor is understandable, but the reality is brutal. For god sake, people have difficulty walking straight in puny 30 knots (level 7 on Beaufort scale)
Wind power is cubic not quadratic with windspeed. 40^3/20^3 = 8 times more powerful.tegirinenashi wrote: It is quadratic (not linear). For instance, the forces involved in 40 knots conditions are 4 times stronger that those at 20 knots.
Have you flown in these winds with kites of these size?tegirinenashi wrote: Power is cubic indeed. Lift is velocity squared. This brings up one interesting corollary: don't get your kite moving under the high wind, otherwise all this power might unleash.
BTW, this square/cubic dependencies bring up another consequence: power vanishes rather abruptly at low end. If a kite falls down from the sky at 5 knots, its redesign with 10% weight reduction is not going to make any noticeable impact.
