The Antonov An-178 (Ukrainian: Антонов Ан-178) is a short-range medium-airlift military transport aircraft designed by the Ukrainian Antonov company and based on the Antonov An-158 (An-148-200). It was announced on 5 February 2010, rolled out on 16 April 2015 and the first flight was on 7 May 2015.
The An-178 is proposed to replace outdated aircraft like the Antonov An-12, Antonov An-26 and Antonov An-32. The aircraft will have avionics suite similar to the An-148, and will use Progress D-436-148FM engines.
The An-178 is a potential competitor for the Alenia C-27J Spartan from Italy, EADS CASA C-295 from Spain, Lockheed Martin C-130J from the United States, Embraer KC-390 from Brazil and the Ilyushin Il-214 from the Russian Federation.
The company plans to build more than 200 of the aircraft.
Design and development
An-178 is a high-wing transport aircraft with moderately swept wing, winglets and a T-tail. The airframe is made of aluminium alloys and composite materials. The fuselage is semi-monocoque with a circular cross-section.
The retractable landing gear consists of two main wheel bogies and a single nose wheel. The flight control system is dual duplex fly-by-wire system, consisting of two parts: FCS-A and FCS-B, each of which is responsible for two control channels.
The flight control surfaces include ailerons near the wing tips, four control spoilers, six lift-dump/speed-brake spoilers, rudder and elevators, with an emergency mechanical cable back-up system. The powerplant consists of two Progress D-436-148FM turbofan engines, mounted on pylons under the wings and an auxiliary power unit. It can shift 18 tonnes over 1,000 km, or 10 tonnes over 4,000 km.
The wing outer panels (including winglets), front fuselage with cockpit and nose wheel leg come from the An-158. The cargo hold is slightly enlarged, and there is an extra pair of main-wheels on each side. The aircraft made its Western debut at the 2015 Paris Air Show.
