- Hi. In this video we look at why Aircraft's have dihedral or anhedral wings. I made this video based on a request I received from a Subscriber.
The video takes us through the basic classification of wings and why the aircrafts have Dihedral or Anhedral wings. It shows and compares roll stability and roll performance.
Hope you enjoy.

Thank You.
I found this by chance looking up the word "dihedral" and it's very well-explained, thank you!
You are welcome! Do check out my other videos as well!
Clearly articulated, loved it!
Glad you liked it!
the best go to when trying to understand! thank you!
Thank you!! Please do check out my other videos as well!
Doing an amazing job keep it up!
Thank you so much! Do check out my other videos as well!
You earned a sub. Thank you for this video
Thank You!!
Clear and great explanation!
Thank you! Check out my other videos as well!
Thanks
Welcome
Nice video
Thank you!
Very clear sir
Thank you so much sir ... Kindly upload one video about Types of drag please sir ....
thank you. will do a video on drag soon!
Can you explain about antnov aircraft wing?? It is Anhedral wing and also swept back wing.it can carry more load than normal aircraft like b747 etc.
the antonov wings are designed in such a way that they carry more weight, and a high wing makes loading easier!
hi sir i am from nepal pls make videos of all antenna function in aviation aircraft
Yes, Noted!
Ur explanation is so good
Thank You! Do watch my other videos as well :)
2:11 why is the AOA of the lower wing added up, i'm a little confused about that part, everything else is fine
Because of the disturbance the wing is moving downward which seems like an increase in the AOA on that wing.
Oh aerodynamics is amazing, i got it thx man
@@JxJAVIATION But this would also work on an aircraft with no dihedral. The dihedral effect comes from the sideslip movement resulting from an imbalance of forces. Therefore the wings get a sideways airflow with the lower wing at a higher angle of attack.
Engines mounted on wings for better ground clearance? VS. what? Mounted on the tail?
That's one way to look at it!
It should be noted that the thumbnail and summary graphic make an erroneous assumption or indication that the Dash 8-400 aircraft has anhedral wings. It does not. Though anhedral is common on high winged jets, turboprops are commonly designed with dihedral wings. The Q400 is no exception.
Yes. Thank you for your valuable input!
But theres RC High Wing use Dihedral configuration.. why is that
now a new question: why do some aircrafts have low wings and some have high wings
Depends on the stability that is required and the performance requirements!
in the last picture you showed turbo prob Dash 8 . it has high wing with dihedral effect .. its not anhedral !
oh yes. That's a very good observation. My Apologies! Will pay more attention to the pics next time!
The explanation for the increased stability of the high wing regarding the center of gravity doesn't seem plausible to me.
the high wing provides better roll performance because of the distance between center of lift and center of gravity
@@JxJAVIATION Why does this distance result in better roll performance?
Because the resulting force applied along that distance or moment arm produces a moment which induces stability
This video is a series of one error after another.
Kindly explain! I make my videos based on several hours of research so would be good if you mention the errors please
This explanation is completely wrong. First it should be known that a dihedral wing does not change its forward angle of attack directly, but when rolled, this is a result of side slip that changes the relative wind. The high wing aircraft has anhedral to add roll stability, to blank out the fuselage with the wing. Consider aerodynamics of side air pressure on the fuselage, different between high and low wing airplanes. The plural of "aircraft" is "aircraft".
Thank you for the information! The change in AOA is felt by the airflow because of the disturbance causing an increase in lift in the downgoing wing. The plural of Aircraft is a mistake I made and could not change!
Not completely wrong, but the reasoning behind anhedral is not well explained, and while flex does play a small role, most high wing aircraft with anhedral do so to overcome the “dihedral” effect of wing sweep. The body also contributes to “dihedral “ effect adding roll stability when below the wing, and subtracting from ii when above the wing.
Trite and incorrect in places
Elaborate please
Sorry to repeat this frequent "fault-finding impulse". Aircraft is plural and no need to add 'S' like Aircrafts. No offence.
Yes. I learned it after publishing this video!
