Question

Can someone tell me about elevons used in modern planes?

Answer 1

Elevons are combinations of elevators(the attachement to the horizontal fin found on the tail of the aeroplane which is rotated about a hinge up and down, generally used for pitching motion) and ailerons...(these fundamentally are used for pitching motion)
So an elevon helps in performing both motions: pitching and rolling
And is generally used in delta planes...

Answer 2

Dear ANIKTOM,
Thanks for your beautiful question. Yes, technically, and elevon is an aerodynamical structure which is specifically used to create both roll and pitch. Elevons act as an hybrid of elevators and ailerons which are controlled by movement of the wingspanpit's yoke. Thus it serves both the purpose. However let me also tell you, heavy aircrafts using only elevons as the basic control surface faces maneuverability problems but although it is extremely beneficial for the case of military and civil modern aircraft which operate in high speed conditions due to the high rate of airflow over their wings allow the elevons to work perfectly and also helps specifically stealth military aircrafts to reduce their radar signature. An excellent military aircraft example is the Avro Vulcan, one of the first delta winged subsonic bombers of the Royal Air Force used in the Falklands War.
With regards,
