Another interesting bit about something called LEVCONs (Leading edge vortex controllers) that one can see in the image in the prev post extending
along the forward edge from the wing root
For the Naval LCA it is defined as follows:
LEVCON ( Leading Edge Vortex CONtroller ) is a deflectable aerodynamic device in wing apex region LEVCON surface is deflected +20 (down) to 30 (up)
from its neutral position.Downward deflection of LEVCON is used for reducing aproach speed for carrier landing.
Not sure if this is present on any existing other operational or soon-to-be operational fighters (incld the IAF version of the LCA) but something
similar (or the very same thing?) is on the T-50 in the form of movable LERXs.
Huh. Its like flaps for the wing-tip vortices. Kind of a cool idea in theory. I wonder how well it works in practice, and if the extra weight and
complexity of the system is really worth the *probably* small decrease in stall speed in a dirty config ( as in landing on a a/c carrier).
