kallend 2,174 #1 January 19, 2004 See Sunday's quiz. www.dropzone.com/cgi-bin/forum/gforum.cgi?post=864480#864480 One of the balls is a Vladiball which deploys its parachute at 1500ft. where the wind is 40kt. Do the following balls hit it? Edited to say: Don't know what a Vladiball is? Check www.vladiball.com... The only sure way to survive a canopy collision is not to have one.

velo90 0 #3 January 19, 2004 As I said in the other thread, you can setup the parameters to cancel out ground speed , or you can set them up to cancel out air speed. If you want to educate people, give them the whole story. Dave Quote Share this post Link to post Share on other sites
velo90 0 #4 January 19, 2004 Sorry, I forgot to answer the quiz Each Vladi ball would deploy in the same spot. After deployment, they have 8 seconds to fly away on their parachutes before the next one deploys. Dave Edited to add: No they won't collide. Quote Share this post Link to post Share on other sites

And no, they won't collide, showing that even with groundspeed=zero you don't necessarily get no separation in the air. The moral of all this is that there's no simple rule that works in all situations. You just have to understand the problem at a fundamental level....

rehmwa 2 #7 January 19, 2004 You have to split the altitude up into the airspeed layers, calculate the time each object spends in each layer, use that to calculate drift. add it all up to get total movement. It's just accounting...... anyway, aren't you supposed to wait until the ball is at a 45 degree angle from the plane before letting the next one go? (I'm kidding, I'm kidding) ...
