Why is it important to resume flight testing of the Il-114-300 airliner?

A few days ago it became known about the resumption of the flight test program for the regional passenger airliner Il-114-300. This event is important not only for domestic air transportation, but also for the whole family of domestic aircraft.

"Good galoshes"


Anyone who flies on domestic flights knows that sometimes in order to fly to a neighboring region you need to change from one flight to another in Moscow. Using the capital's transport hub for their connections turns out to be easier and cheaper than constantly driving the existing fleet on domestic flights.



This problem can be solved by using a specialized regional airliner designed to carry from 20 to 110 passengers on routes with a range of 500 to 1500 km. In the USSR, aircraft such as Il-14, An-24, Yak-40 and Yak-42 were used for these purposes. In the late 80s, the Ilyushin Design Bureau developed the regional turboprop airliner Il-114, designed to transport up to 60 passengers in the most difficult climatic conditions from unpaved, ice and other poorly prepared runways. Just what the doctor ordered for our country!

It’s only after the collapse of the Soviet Union that the aircraft factory producing these aircraft, namely the Tashkent Aviation Production Association named after. Chkalov (TAPOiCh), remained on the territory of sovereign Uzbekistan, and the Il-114-100 series itself was limited to only ten aircraft. It would seem, why even bother with the development of some kind of regional airliner if Russia already has a short-haul Superjet-100 airliner?

But no, the commercial operation of a turboprop aircraft such as the Il-114 in the regional air transport segment with its harsh runways turns out to be safer and more profitable than the Superjet with its low-mounted engines. After the introduction of the first Western economic sanctions, it was decided to transfer to our country from Uzbekistan the production of a modernized version of this aircraft, called Il-114-300.

Externally, the plane remained almost unchanged. Its length is 26,9 meters, height is 9,2 meters, and its wingspan is 30 meters. TV7-117ST-01 engines received a new electronic control system, an optimized component base, became lighter and increased power to 2800 hp. at takeoff with a maximum of 3100 hp, which is about 12-14% more than the base version. New six-blade saber-shaped propellers AB112-114 were installed, which made the operation of the power plant less noisy. The weight of the airliner has decreased by a ton, which has reduced fuel consumption.

The first prototype of the Il-114-300 with new TV7-117ST-01 engines took off in 2020. Here it is, a real competitor to the unrealized short-haul Superjet-75, which could easily work on domestic airlines, but its fate turned out to be difficult.

Flame Engine


On August 17, 2021, a light military transport aircraft Il-112V crashed near the Kubinka airfield near Moscow while performing a training flight. The plane caught fire while still in the air and crashed to the ground. In this case, three famous test pilots on board were killed.

Unfortunately, this plane crash made significant adjustments to the program of not only the long-suffering Il-112V, but also two other domestic aircraft - the regional passenger airliner Il-114-300 and the Mi-38 helicopter, which used a modification of the same power plant. As a result, the United Aircraft Corporation (UAC) decided to suspend testing of all these devices:

It is necessary to analyze the details and circumstances of what happened with the Il-112V, including the analysis of objective data from the flight recorder. Therefore, test flights of the prototype Il-114 aircraft, equipped with a similar power plant, will not be carried out for some time.

Even then, it was criticized by the relevant Deputy Prime Minister Yuri Borisov, who considered it wrong to suspend the operation of Mi-38 helicopters and promised to bring the military transport aircraft to completion:

The Il-112 program will definitely be promoted, because it is a popular light transport aircraft. Unfortunately, tragedies of this kind do happen, and I think that the industry will draw appropriate conclusions, understand the reasons, and develop the necessary set of measures.

However, then something completely strange began. During SPIEF 2023, Deputy Prime Minister and Head of the Ministry of Industry and Trade Denis Manturov said that the Il-112V military transport aircraft project will be modified, technological changes will affect the design of the wing and engines. Last summer RIA News citing An informed source reported the following:

The Il-112V design is planned to be reworked for PD-8 jet engines. In particular, a number of changes will be made to the aircraft wing structure, fuel system and other onboard systems.

From the outside, it looked as if eliminating the problems with the power plant during its boost had not been possible, and therefore it was decided to completely remake the light transport aircraft, which was urgently needed by the Russian Ministry of Defense. However, at the same time the enterprise "ODK-Klimov" заявило, which in 2024 will supply the first six engines for the needs of the Il-114-300 project:

Two engines are now “on the wing”, the remaining engines are undergoing modifications after the first stage of testing. Pre-production production of three aircraft is also planned. In 2024, starting from the first quarter, we plan to supply at least six more engines in serial form to support the IL-114-300 program.

And at the beginning of March of this year, it became known that the airline OGUP Kolyma Aviation received the first two Mi-38-4 helicopters from the Kazan Helicopter Plant, which under their own power reached their place of registration in Magadan. Il-114-300 resumes flight tests.

It turns out that we have figured out the engines for a civil airliner and a helicopter, but what about their forced version for a military transport aircraft? Is the rather controversial project of re-engining the Il-112V with PD-8 engines still in force? Here is the main intrigue.

    As an armchair analyst and an irresponsible person, I declare with a large share of hey-likes that thus the TV version of the Il-112 is being held back until the TVRS-44 appears, but there will be an Il-212, there won’t be... The An-72 was also not very widespread - t It doesn't "burn".

      What is the relationship between two aircraft with different purposes (IL-112 and TVRS-44)?

        How different? Just ask for the sake of decency.

          Yes, completely different. Il-112 is a truck, and TVRS-44 is a passenger airliner.

    The Yak-42 is not a regional/short-haul aircraft - it is a medium-haul one for 120 pax.

    The commercial operation of a turboprop aircraft such as the Il-114 in the regional air transport segment with its harsh runways turns out to be safer and more profitable than the Superjet with its low-mounted engines.

    And why didn’t the author write that the IL-114’s propellers cling to the ground - this is from the same pack of myths as the suction of stones into the Superjet engines. laughing
    And the advantage of a tubeprop over a tubeprop (a jet is....) is greater thrust at low speeds and the ability to change the pitch of the propeller, which allows you to sharply accelerate or brake. Those. you can take off/land on runways more than 2 times shorter (and narrower) than those required for a Superjet. This reduces the cost of flights and expands the airfield network. Plus, the IL-114 does not require airfield maintenance (even its own ramp).

    Last summer, RIA Novosti, citing its own informed source, reported the following:

    The Il-112V design is planned to be reworked for PD-8 jet engines. In particular, a number of changes will be made to the aircraft wing structure, fuel system and other onboard systems.

    Fdnjhe should not have spread the nonsense that his stupid brother wrote.

    112 again! With PD-8 we are talking about 212, with a payload of 10 tons. This is also a very useful aircraft.

      Which you have to “carry” with you, spending fuel on this cargo.
      On the other hand, if there was an accident and they landed in a field, then you can’t bring a ladder there... Another option is to add a rope ladder, but passengers are different: not everyone can go down such a ladder.

      In general, aircraft specialists still have work to do. )))

      By the way, I’m pushing an idea: passenger seats also weigh a lot, so they can be made inflatable or made of soft material (down or porous material). And if we generalize this idea, we can get... an inflatable plane!
      Yes, not everything is thought out - it can deflate in flight, but that’s it for now...

      After all, they crossed the ocean in a rubber boat, without water or food:

    Author, there is no remotorization of the Il-112v. This is too huge an engine for such a small aircraft. There will be an Il-212 aircraft, probably something between the An-72 and An-12, and PD-8 engines will be installed on it.

    The IL-114 is a good car...give it a modern, reliable engine and it will fly...and it will fly well...And the Russian Federation needs cars of this class...The An-24 has already flown its life and they needed a replacement just yesterday...
