new NLCA MK2 has Vortex flaps.
I am surprised to see no one has pointed it our so far.
I did not not point it out because the LEVCons are used currently in the same manner. But, there is something wrong in that diagram or that flap is really oddly shaped. Are they going to have a flap which stands up like a spoiler at the LE?
While Levcons are used at 30deg angle, vortex flap will be kept at much higher angle, may be even 90deg just like a spoiler. But spoilers are perpendicular to airflow, these will be along LE. Cant say with surety about final config for landing as of now. We dont have sufficient info.
When I was looking for Levcon in literature like 4yrs ago, I hit a lot of papers on Vortex flaps. Functionally Levcons in Landing config of 30deg up are same as vortex flaps. But Levcons can be used as LE slats as well with downward deflection.
