Ilyushin IL-114

IL-114 – a regional turboprop passenger aircraft, created in the Design Bureau Ilyushin in the late 1980s. It was produced in a small series in the 1990s. It is planned to resume serial production at the UAC facilities in the early 2020s.

History

The early 1980s marked a milestone in the history of regional air travel. Almost simultaneously, a new generation of aircraft was created in Europe, the Americas. Aircraft of the ATR, Q-series, Fokker 50 family was reliable, economical and cheap. All of these aircraft were turboprops. This was characteristic: the days when everyone was obsessed with jet engines and went after speeds passed – the speed at short distances is not so important, and the reliability and efficiency of a turboprop engine gave a huge advantage in conditions of constantly rising fuel.

In the USSR, it was also decided to create a new generation aircraft. In the conditions of a huge country with a large number of remote inhabited and industrial zones, a jet plane was necessary, and the An-24s flying at that time no longer met the requirements of the time, and most of the fleet was on the verge of running out of resources.

Already in 1982, the Ilyushin Design Bureau began to consider the creation of such an aircraft. It was also decided to make the aircraft turboprop. Although the bureau at that time was actively engaged in the IL-96 project, the importance of a small regional plane was high and the IL-114 project was approved in 1986.

Unlike analogs, the IL-114 was created as a platform for many modifications. Also, he was calculated to work in rather severe conditions of short, unpaved strips, glaciers, both high and low temperatures, and so on.

The first flight of the prototype IL-114 made in 1990. Flight tests were carried out in various conditions in Tashkent, Yakutsk, and Arkhanshelsk. The aircraft was actively shown at air shows in the 1990s, however, the loss of interest on the part of both Russian and foreign airlines led to a budget deficit in the project and delayed trials. The aircraft was certified only by 1997.

Production was established at the Tashkent Aircraft Plant, but production volumes were minimal. In the end, the assembly of new machines was curtailed after the creation of about 20 pieces.

Presumably, the new aircraft will be delivered to Russian airlines and government agencies, as well as exported.

In 2017, the United Aircraft Corporation (UAC) and the United Engine Corporation (UEC) officially launched work to modernize the aircraft and power plant.

Features

IL-114 is a twin-engine turboprop low-wing with a direct wing and a single-tail tail.

On the wing, there are two turbo-propeller engines TV7-117C, developed at the Plant named after Klimova. The engines are equipped with low-noise six-blade screws SV-34 with a diameter of 3.6 meters.

The fuselage has a cross-section of 2.86 meters and accommodates a fairly large cabin for aircraft of this class, made according to the scheme “2 seats – passage – 2 seats”.

Cabin “glass” with an interface of five displays. The complex is deeply automated and allows you to fly day and night, including in regions with underdeveloped aviation infrastructure. Management is carried out by two pilots.

The IL-114 wing was designed based on extensive research and experimental work carried out by OKB together with TsAGI. It has a high level of aerodynamic and weight perfection and is equipped with effective take-off and landing mechanization, consisting of retractable double-slotted flaps.

 
Modifications

  • IL-114T. The design of the cargo variant was launched in the second half of 1994. The IL-114T differs from the original version by a cargo compartment equipped with floor-mounted mechanization, ensuring quick loading and unloading operations, and a side door located on the left side of the fuselage behind the wing. The aircraft is capable of carrying goods weighing up to 8 tons.
  • IL-114-100. Another designation – IL-114RS – version with a PW127H Pratt & Whitney Canada TVD with a capacity of 2750 hp. each. It received a certificate of AR IAC in 1999. Installing a new engine has reduced fuel consumption and increased range. Operated by O’zbekiston Havo Yollari.
  • IL-114LL. Flying Laboratory, commissioned by the St. Petersburg Scientific and Production Enterprise “Radar Mms” in 2004 to test the manufactured equipment. The general public was shown at MAKS-2005, where he made several demonstration flights.
  • IL-114-300. Two TV7-117CM turboprop engines with a capacity of 2650 hp are installed on the aircraft. and updated on-board systems. This model is planned to resume production.
