Gliders normally have negative angle of incidence. The angle of attack is always neutral to positive glider or plane. Angle of attack in a fluid...
Spot on with almost everything. But a glider must maintain some pitch below the horizon or it will lose air speed. No matter if in lift or sink...
Tie a rope to a glider in enough wind and you can. It's the same as putting an engine on. It doesn't depend on wind. You are replacing thrust Do...
But I didn't say they could only move towards a depression. Similarly a glider does not always need to move towards gravity. This is not what we...
For a sailboat. You can change the angle of the sail in relation to the centerline. But for a given heading there is a correct setting . Oversheet...
I reccon that cl is quite high. It was only a guestimation based on another guess of the foil having 4.5° aoa. But after doing 0 experiments on...
Don't fear. I know perfectly well how they work as a paraglider and rc glider pilot. Then you should also know that a sailboat cant go either in...
No. A glider gains forward speed from the forewarned component of lift. It stays aloft because of the upward component of lift. Gravity does not...
The media in which they travel has no bearing on the dynamic interactions of the vehicle. Its gravity vs air or water vs wind.I understand that if...
So right on que the remote control and servos arrived and I had to throw something together to get a feel for it. And this was the result.
Bravo. I literally couldn't have put it better myself (No matter how hard I clearly tried.). Good learning experience, brilliant exchange of...
Yes that is correct. Using this point to further the conversation, it really does not matter which way you decide to set the x,y,z axis. It really...
I think we are all in agreement now. Does sailor al want to pick apart any of the points made.?
Poetic.
I'll be sailing my one on fountainstown back strand. Ireland.
What do you mean solid wing sails don't have visual clues for guidance. ? Like backing the leading edge of the sail when undersheeted or tell...
And again i apologise for awful formatting my posts are taking. I still haven't figured out how to post on the forum. What I'm saying keeps...
And are gathering and accumulating not the same thing. You said I was wrong and should go read the physics again and then say the same thing I...
In the scenario you've given, what is the "useful" form of energy you are referring to that isn't wind. Gravity is not a force. Being held...
That's ok . I agree "gathering energy"is a misnomer. I think the underlying assumption is that the discussion is about boat or planes moving in...
