The start of the An-140 program was announced in June 1993 at the 40th International Aerospace Salon in Le Bourget – General Designer P.V. Balabuev for the first time officially announced the start of work on a new An-140 passenger aircraft.
In April 1994, it was planned that the An-140 would surpass the performance of the An-24 in basic parameters.
The task was extremely clear – the aircraft should be simple, as reliable as possible, comfortable for passengers and crew, convenient to operate, and cheap to manufacture.
In February 1994, the An-140 program received the status of the State.
The regional An-140 was first presented to the international public at the international aerospace exhibition Farnborough International 2002, held in July 2002 in Farnborough, a suburb of London. The new aircraft also successfully passed repeated tests of tough operation. At the end of 2002, at the Air China 2002 exhibition in the Chinese province of Juhai, the An-140 and An-74TK-300 aircraft made their first extra-long flight with a length of 20,635 kilometers in 54 hours, setting a kind of record for regional air transport of its category. The aircraft successfully crossed the route Kharkiv (Ukraine) – Kish Island (Iran) – Bombay (India) – Calcutta (India) – Bangkok (Thailand) – Juhai (China) – Bangkok (Thailand) – Calcutta (India) – Bombay (India) – Ras Al Khaimah (UAE) – Kharkiv.)
The all-metal An-140 is a twin-engine monoplane with a highly located non-swept wing and a three-post wheeled landing gear retractable in flight. The aircraft fuselage has a circular cross-section and is divided into a crew cabin, a passenger (cargo) cabin, designed to carry 46-52 passengers, and a rear luggage compartment with a volume of 6 m3 located in the tail. An underground cargo compartment with a volume of 3 m3 located under the floor of the cargo compartment can also be used for cargo placement.
The aircraft has an off-road chassis with low-pressure pneumatics. In-flight, the front landing gear retracts into the fuselage and the main struts – into the fairings located on both sides of the fuselage.
The engines of the power plant are installed in nacelles under the wing. It is planned to equip the aircraft with two turboprop engines TVZ-117 VMA-SB2M with a capacity of 2500 liters. with. each developed by NPP them. V.Ya. Klimova (Russian Federation) and Motor-Sich (Ukraine) software, or engines of the American company Pratt & Whitney PW-127A, about the same power.
The aircraft also has an auxiliary power unit located in the rear of the fuselage and providing autonomous operation of the aircraft at unequipped airfields.
The design of the aircraft in its structural and technological solutions has a high continuity concerning the design of the aircraft An-72, An-74, and An-24. So, the main range of materials and semi-finished products used in the design of airframes and systems is a traditional and mastered aviation industry.
