View Full Version : Sweepback effects on a flying wing

I have done a search on this and have found a few answers

more sweep:

1) produces more effective dihedral
2) reduces loop ability
3) increases roll rate
4) increases drag
5) increases bleeding off speed in turns
6) decreases sensitivity to exact CG

Are these correct?

What effect does aspect ratio have on a swept wing?
Higher = better glide but less stability at close to stall speeds?
Lower = better aerobatics and more stability at close to stall?

How much does sweepback affect the ability to loop? Is it dramatic with small changes or the opposite? If I have a wing barely able to loop from level at say 55 degrees SB would changing the SB to 110 cause it to no longer loop?

I think that the reduced ability to loop has to do with the added drag at higher angles of attack ("increases bleeding off speed in turns").
