These are the first official DRDO images of fabrication of compact advanced serpentine air-intakes, intended for preliminary studies on performance. The DRDO plans serpentine air intakes on its Advanced Medium Combat Aircraft (AMCA) and the
IUSAV stealth UCAV. Recently posted a
new cutaway image of the impression airframe, throwing new light on the aircraft's stealth and design elements. Much more about the AMCA's stealth elements
here.
