Airframe of AMCA

Today we will discuss about airframe of AMCA 

———————————————————————–

AMCA is envisioned to use carbon-fibre composites (C-FC), and titanium alloy steels for airframe construction. C-FC materials will be used in 80%  of  airframe by weight. It will also be used in the fuselage (skins and doors ), wings (ribs , skin, and spars), tailfin, elevons, rudder, air brakes and landing gear doors. The advantage of using composite materials is that it makes an airframe lighter and stronger at the same time compared to an all-metal design. AMCA is supposed to employ the highest percentage of composite materials for any other aircraft. Employment of composite materials helps in the fact that there are fewer joints and rivets, which increases the aircraft’s reliability and lowers its susceptibility to ural fatigue cracks in its structure with the majority of these being  bismaleimide (BMI) and composite epoxy material. AMCA will also use structural nanocomposites, namely carbon nanotube reinforced epoxy. Stressed ducts in S-shape are rivetted with airframe with the loaded bulkheads constructed off composite materials spanning the aircraft from air intake to engine shafts.
