KAI KC-100-naraon-"2011"

The KAI KC-100 Naraon is a South Korean four-seat, low-wing, single-engine light aircraft developed and manufactured by Korea Aerospace Industries (KAI). The name Naraon was chosen based on public input. It has the distinction of being the first civil-orientated aircraft to be developed in South Korea.[2]

Keen to break into the civilian market, KAI formally launched development of the KC-100 during 2008. While largely conventional in its basic configuration, use of composite materials and the adoption of cutting-edge technologies were intended to allow the new aircraft to be 10% more fuel efficient than existing rivals. On 15 July 2011, the prototype KC-100 performed the type’s maiden flight. The flight test programme was completed successfully on 22 March 2013, shortly after which the aircraft received type certification, permitting its use by civil operators


The Korean Aerospace Industries KC-100 is a four-seat light aircraft intended for general aviation purposes, such as small-scale commercial and commuting activities, flight training, and leisure and private flights.[1][2] It possesses an all-composite airframe, being constructed primarily from carbon fibre. The use of such materials reduces overall weight, simplifies manufacture and reduces maintenance costs. The spacious cabin has been designed to appeal to both leisure and business customers. Access to the cabin is via gull-wing doors on both sides of the fuselage.[1][9]

Significant attention was paid during development to the KC-100’s aerodynamics; for example, the wing employs a laminar flow airfoil and has winglets, while the flight controls incorporate an aileron-rudder interconnection (ARI) system, the latter being aimed at augmenting the aircraft’s lateral stability.

During May 2014, the South Korean Air Force (SKAF) academy entered a memorandum of understanding to obtain a military trainer variant of the KC-100, designated KT-100; this was the first mass production contract to be received for the aircraft. Once delivered, the KT-100 fleet will replace the 20 Ilyushin Il-103 aircraft currently stationed at the academy, where they shall be used to familiarize students with flying.[15] On 5 October 2015, the first KT-100 conducted its maiden flight; at that point, all aircraft were expected to have been delivered by the end of 2016.
