It's no different than a glider. The rotor blades are just glider wings turning in a REAL tight circle. As the device drops, air rushes over the rotor, causing it to spin (you do have to tilt the blades a little). As it spins, air goes over the airfoil shaped blades creating lift to offset the weight of the device. As the weight is offset the acceleration down drops. As you accelerate, lift force increases. At some point lift and weight are equal and you descend at a steady velocity. IF you do your part right that velocity will be low and the egg will survive.Thanks, but I'm still not seeing how this would decrease times in any noticeable way, considering the weight of the egg. It would seem to me that you would need power to spin the blades fast enough to slow the descent.
We tried this at Wright State this year.I would also like to say, in the rules it says that "a" roter may be used, this means that there can only be one rotor on the device correct?
First place team was a little under 6 seconds. Only 2 teams got a better time (approx +.1 & +.6 sec) & both of their eggs broke.Any national times?
