1. These are called dihedral Angles

2. Anhedrals and dihedrals: aerodynamics Martin (Blake14) First Officer

3. Anhedral is an antonym of dihedral

4. Whereas, dihedrals (wing angled upwards) are more stable than Anhedrals

5. Angle of geometric visibility (dihedral with horizontal edge)"

6. Angle of geometric visibility (dihedral with horizontal edge)

7. As adjectives the difference between Anhedral and dihedral

8. The same goes for tailplanes, canards or Anhedrals/dihedrals if they are folded.

9. Anhedral fins (sometimes incorrectly called dihedral fins) Yeah, I absolutely agree that they should be called Anhedrals, but they are definitely labeled "dihedral planes" on the drawings.

10. Working on dihedrals and Anhedrals can make you change the flight of your boomerang

11. In contextaeronauticslang=en terms the difference between Anhedral and dihedral is that Anhedral is (aeronautics) the downward slope of an aircraft’s wing while dihedral is (aeronautics) the upward slope of an aircraft's wing

12. Values of 3JCC are found to be influenced by both dihedral angle and valence angle.

13. 19 The complete design team photographed before modification to give greater dihedral on the outriggers.

14. If too much, negative dihedral (Anhedral a down-sloping wing angle) may be needed to counter their effects

15. The opposite of dihedral is called Anhedral, and, of course, refers to a wing that is angled down

16. Click on the picture below to see how the energy of the Conformations vary with dihedral angle

17. Dihedral/Anhedrals seem like they would be much easier to analyze than curved surfaces for their effects

18. Main Anhedrals: 7 1/2% Walchner 'C' section, chord 30" Main Dihedrals: 7% Walchner 'C' section, chord 18" to 30"

19. Anhedral was used to offset the dihedral effect and other stability factors of its highly swept wing and tail.

20. Sorry for going off topic, but I would appreciate some more aerodynamics posts: the one on Anhedral and dihedral was especially good

21. The curve is sinusoidal and represents the alternation of the dihedral angles at which the alkane Conformations are the most stable and least stable

22. Dihedrals and Anhedrals angles If you observe your boomerang, you see that it is tuned like an air wing with a flat side and a tuned side

23. : the angle between a downwardly inclined aircraft wing and a horizontal transverse line The bottom wing had pronounced Anhedral; the upper wing, dihedral

24. Aperiodic tilings On the previous page we introduced nonperiodic tilings and we gave examples of a monohedral nonperiodic tiling and a dihedral nonperiodic tiling

25. Upward angled wings of low wing Aircraft are known as dihedral wings & Downward angled wings of high wing aircraft are known as Anhedral wings

26. This analysis supports the model used by previous MD studies that measured dihedral and opening angles of Actins [ 4 , 13 , 32 ], and provides a verified metric

27. I couldn’t really be bothered with the Anhedrals and Dihedrals because I still operate on an older version and the finetune doesnt accound for angles on wings when mirroring.

28. High wing => adds roll stability (and the opposite) Dihedral => adds roll stability (and the opposite) So: you can have a high wing Anhedral plane still roll stable

29. Bow Anhedrals: 7 1/2% NACA 16-40 section, chord 16" Lower Bow Dihedrals: 7% Walchner 'C' section, chord 8" to 16", changed to Tulin-Burkart two-term loweer surface, super-ventilating

30. Anhedral - the tips are lower than the root, as on the Ilyushin Il-76; the opposite of dihedral. Used to reduce stability where some other feature results in too much stability.

31. "Anhedral angle" is the name given to negative dihedral angle, that is, when there is a downward angle from horizontal of the wings or tailplane of a fixed-wing aircraft

32. Dihedral is where the wing slopes in a positive (upward) degree in relation to the wing base, whereas Anhedral wings have a negative (downward) slope from the wing base. Let’s explore a little further on why designers chose one over the other.

33. A catamaran or V-bottom hull (20) is modified with chine mounted aerofoils (32, 33, 28, 28A), flexible dihedral cambered foils positioned beneath the water line and on either side of the bow (30, 31) so as to create turbulence in the forward end of a tunnel(s) (26).
