Wing Shape Change Question?

Postby Chris McKeon » Tue Oct 04, 2022 9:44 pm

I have had thoughts regarding My Predator. So When I Fly along while easung the bar out. As I approach The point where I am in Mush Mode,I am kissing the point where My Predator will Stall. I then will pull the Bar in so as to initiate the Entergy dive. So after accelerating. at the bottom of my Energy dive i will apply a small amount of Roll then i will enter the climb of my Maneuver. Well as We all know when We do a Wing over, part of what happens is that We apply positive G-Loads to our Gliders. What I would like to know is; When My Glider is pulling more G's, does the Wing's shape change thus either increasing or decreasing the Wings ability to create lift?

Yes. The Wing has a distinct shape at each wing loading. At zero loading there is a resultant shape. Let x be a variable real number greater or equal to zero. At loading xG, there is a distinct shape of the Wing corresponding to any specific x. Let us symbolize the distinct shape at x as Sx As a spring within limits of actions, a Wing may go to higher x and be able to experience lesser x choices; but at some higher x experiences, the Wing will experience such shape changes that will not permit returning to earlier shapes with earlier or lower x values. At some value of x, the shape will become called "drastically broken shape" whereupon erratic motions may occur and fun may end. :o

Well it is Wednesday at One O'clock Noon i just got off the Phone from Talking with John. I told Him that when I get back to flying My Predator. I want to do make the effort to do an Loop on My One Fifty Eight Predator, to do an Over the Top One Hundred and Eighty Degree Wing-Over, as in a Loop. We talked about how I have gone over the top as in I don't know? Maybe I have gone as steep as 170 degrees or so. I always maintained tension in the Hang-Strap. Well john and I talkede about how close i was to doing a Loop. But Close is no Cigar. I intend on doing a loop safely.

I have flown HG's for about twenty Years. It has been, and it might be a long time Yet to come for when i loop My One Fifty Eight.
