The integrated wind tunnel model of the AMCA Mk1 shows some of the design characters that will be included at least in the Mk1 variant of the jet from the start. The scaled Model showcases a Diverterless Supersonic Inlet (DSI) that will addition of the 3D bump will help in concealing engine blades from radar waves from bouncing back to their source, and serpentine air intake will further improve the stealth and design elements of the aircraft.
AMCA sports an advanced Infrared search and track sensor (IRST) in the traditional position installed atop the aircraft’s nose, near its windscreen, there is chatter that the IRST system is retractable which will make it the first of its kind. Although the placement of the IRST sensor will hurt the radar signature on the forward fuselage section, it could be a stop-gap measure at least for the initial prototypes till DRDO can come up with its own Distributed Aperture System (DAS) style system in Mk1 or Mk2 variants of the jet.
Some of the smaller things seen on the airframe like a turret mounted dorsally behind the cockpit can’t be verified at this point, but it seems it could be a Directional Infrared Counter Measure sensor that could be used to blind incoming IR missiles which usually follows rear engine heat.
What seems to look like an APU intake unit on the midsection of the spine is a combined pre-cooler and heat exchanger, that will also have a brake chute that is part of the rear fuselage. AMCA will also feature a 23mm GSh-23 twin-barrel internal cannon on its left side just behind the cockpit section.
AMCA will feature Internal Weapons Bay from the start that can carry 4 medium to long range air to air missiles internally or two medium range air to air missiles with two 500kg smart bombs in a stealth configuration.
Above all else, the AMCA program will be incorporating innovative concepts like unmanned operational capabilities, Auto take-off, and auto landing features but rest assured low observable design will see further tech infusion to make it far more deadly when it enters service in 2031 onwards.
