Talk:Thrust vectoring: Difference between revisions

 

If you go to wikipedia's website for "aircraft pricipal axes" <ref>http://en.wikipedia.org/wiki/Aircraft_principal_axe</ref>, it will give you a good idea of the difference between 2D and 3D thrust vectoring (TV). I think there is a mistake on this site, 2D TV from my understanding should refer to aircrafts that can move along two of the three axes (pitch, roll, yaw). For example, aircrafts that have two engines that can go up and down, if both engines point in the same direction, the aircraft will "rotate" along the pitch axis. If the engines move in opposite directions (one points up, the other points down), the aircraft will "roll" along the roll axis, hence the 2D naming. Twin engines that can also move "sideways" will enable the aircraft to rotate along the yaw axis. The problem I have is that the F-16 VISTA and Rockwell X-31 being single engined aircraft, no matter how their respective engines move, the aircraft will only rotate along 2 axis (if you only use the engines, i.e. without the help of ailerons, they will be able to move along the pitch and yaw axes, but cannot rotate along the roll axis), so in my humble opinion these two aircrafts should still be considered as 2D TV aircrafts (pitch and yaw axis) <small><span class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:Hschantang|Hschantang]] ([[User talk:Hschantang|talk]] • [[Special:Contributions/Hschantang|contribs]]) 01:02, 12 January 2012 (UTC)</span></small><!-- Template:Unsigned --> <!--Autosigned by SineBot-->
