41burhan has just replied to a thread you have subscribed to entitled - Dynamic Soaring of Air masses Video - in the Classical Physics forum of Physics ForumsNew reply? I talked to Taras K on the phone. He said since all thermals are bumpy that some dynamic soaring takes place within any...

Well youll have to get out your slide ruler and do some math. What does physics say would be the greater vertical boost- falling thru the lift and pulling up in lift, or falling thru still or slightly sinking air just before entering and pulling up in soaring lift. l meant soaring lift in each...

My point is that some have said that pumping is possible within lift and its just one air mass. Is that true? Do you really need the horizontal wind when pumping on a slope? Think of a skydivers vertical wind tunnel. They can open and close their suits and get higher and lower so...same?

This isn't a slope (confined/contained/limited). So flying in only one air mass would be impossible. Flying aerobatics which makes flying even wider than small circling would make dynamic soaring take place by default. Looks like I answered my own question.

Someone lied to me. Dynamic just means not static. It has nothing to do with the arena of having 2 of anything. rcgldr did you only watch the first 10 seconds of the video?

Rcglr you don't understand what I mean.

http://www.icarusengineering.com/Dynamic-Soaring-and-SE.htm I am trying to validate dynamic soaring versus normal thermal soaring, but both are using thermals as the power source. Dynamic soaring would mean using 2 types of air masses. One in the thermal and the second one is the inflow to...

I think the word is hysteresis.

Looking for a description of low efficiency in Rubber band or Tubing I am looking for a description of power loss in that you don't get out the work you put into pulling latex tubing. I have some new latex tubing that is treated with UV protection and is super hard to pull from the very...
