The United Engine Corporation, a
0:07
subsidiary of the Rosstec State
0:09
Corporation, has reached a major
0:11
milestone in the revival of Russia's
0:13
civil aviation sector by completing
0:15
preparations for the serial production
0:17
and delivery of its latest turborop
0:20
engine designated as TV717
0:25
This power plant has been developed
0:26
specifically for the IL114300,
0:30
a new generation regional aircraft that
0:33
is being introduced to the international
0:35
aviation audience for the first time at
0:37
the Wings India 2026 aerospace
0:42
As Altitude Addicts, the YouTube channel
0:44
behind this deep dive analysis, notes,
0:46
this moment represents the shift from
0:48
promises on paper to hardware ready for
0:51
real airline service.
0:54
Beyond production readiness, UEC has
0:56
also completed the creation of a full
0:59
domestic service and maintenance
1:00
framework inside Russia. This
1:03
infrastructure guarantees long-term
1:05
operational support for airlines and
1:07
operators, covering the entire engine
1:10
life cycle. Together, these steps
1:12
confirm that the program has moved
1:14
decisively beyond development and
1:16
certification into the phase of stable
1:19
industrial output and realworld use.
1:23
This transition is especially important
1:25
in the broader context of Russia's
1:27
regional aviation strategy.
1:32
program is designed to rebuild domestic
1:34
short hall and regional connectivity
1:37
using fully indigenous technology while
1:39
gradually replacing aging Soviet era
1:41
turbo props and reducing reliance on
1:46
At the heart of this effort is the
1:47
latest evolution of the longunning TV7
1:50
engine family now brought to maturity in
1:53
its most advanced form.
1:55
Developed at the St. Petersburg Design
1:57
Bureau of UEC Kleov. This engine is not
2:01
a simple refinement of an older design.
2:04
It has been deeply modernized,
2:06
incorporating digital control systems,
2:08
improved aerodynamics, advanced
2:10
materials, and higher thermal
2:12
efficiency. The goal of these changes is
2:15
clear. Better environmental performance,
2:18
lower operating costs, and higher
2:20
reliability compared with previous
2:24
certification marked a decisive turning
2:26
point. In 2022, the engine received its
2:30
type certificate confirming compliance
2:33
with civil aviation safety and
2:35
airworthiness standards.
2:37
Since then, UEC Kleimoff has
2:40
methodically expanded the approved
2:42
operating envelope through additional
2:43
certification work tied directly to
2:46
flight experience on the IL14300
2:51
These activities led to extensions of
2:53
service life and component lifetimes,
2:56
making the engine more economically
2:58
attractive for operators.
3:00
They also reflected growing confidence
3:02
built on extensive bench testing and
3:05
hundreds of real flight cycles. By 2025,
3:09
the final operational limitations were
3:11
removed, including restrictions related
3:14
to reverse thrust use and maneuvering
3:18
With these limitations lifted, the
3:20
engine is now fully certified across the
3:23
complete flight envelope of the
3:27
This includes authorization for thrust
3:29
reverser use during landing, a critical
3:32
feature for operations from short or
3:34
less prepared runways. As Altitude
3:37
Addicts highlights, this capability is
3:39
particularly important for regional
3:42
routes in remote or infrastructure
3:46
Following certification, the program
3:48
moved to its most consequential phase.
3:51
With the engine formally included under
3:53
a valid production organization
3:55
approval, UEC has received authorization
3:58
to begin serial deliveries.
4:01
This marks the shift from prototypes and
4:03
pre-series units to full-scale
4:05
industrial production. According to UEC
4:09
Kleimoff management, supplier chains
4:11
have been synchronized, quality control
4:13
systems validated, and production lines
4:16
prepared to ensure stable output.
4:19
Equally important, arrangements for
4:21
after sales support have been finalized.
4:24
This includes engineering assistance,
4:26
spare parts, logistics, repair
4:28
capability, and maintenance
4:30
infrastructure, allowing operators to
4:32
rely entirely on domestic support.
4:35
From a performance standpoint, the
4:37
engine is tailored for demanding
4:41
It delivers up to 3,100 horsepower at
4:44
takeoff, giving the IL14300
4:48
strong performance even in hot and humid
4:52
Paired with the modern AV112114
4:55
low-noise propeller, the system provides
4:57
higher thrust, improved climb
4:59
capability, and reduced external and
5:04
Fuel efficiency was a core design
5:06
priority. Lower specific fuel
5:09
consumption in key operating modes
5:11
translates into longer range and reduced
5:13
direct operating costs. For regional
5:16
airlines operating on thin margins, this
5:19
efficiency is a decisive advantage.
5:22
The engine is also designed for
5:24
operation across a very wide temperature
5:26
range from -60 to + 45° C. This allows
5:31
reliable performance in Arctic winters,
5:34
continental climates, tropical heat, and
5:36
aid regions without degradation.
5:40
A key element of this modern
5:41
architecture is the Bark 65SM digital
5:45
control system. This system manages the
5:48
engine and propeller as a single
5:50
integrated unit, continuously optimizing
5:52
parameters throughout all phases of
5:56
The result is smoother handling, reduced
5:58
pilot workload, and improved overall
6:02
Digital integration also enhances
6:06
Maintenance crews gain better visibility
6:08
into engine health, enabling predictive
6:11
maintenance and earlier detection of
6:13
potential issues before they become
6:17
Operational credibility was built during
6:19
an intensive flight test campaign. In
6:23
2025 alone, the IL114300
6:27
accumulated nearly 3,000 flight hours
6:30
across more than 400 flights using this
6:32
propulsion system. These flights covered
6:35
a wide range of payloads, weather
6:37
conditions, and mission profiles.
6:40
The accumulated data confirmed stable
6:43
power delivery, low vibration levels,
6:45
and consistent behavior in real
6:47
operational conditions.
6:49
Engineers also use this experience to
6:52
fine-tune control algorithms and
6:54
operating procedures, ensuring the
6:56
serial configuration reflects realworld
7:01
The international debut at Wings India
7:03
2026 marks a symbolic and practical
7:06
milestone. The IL114300
7:10
arrived in India after a long ferry
7:12
flight across 10 countries,
7:14
demonstrating endurance, reliability,
7:16
and system stability. At the exhibition,
7:19
the aircraft is presented as a fully
7:22
indigenous regional platform from
7:26
During demonstration flights for Indian
7:28
partners, UEC Climov specialists were on
7:31
board directly observing performance.
7:34
The propulsion system delivered stable
7:36
thrust, low noise, and smooth operation
7:39
throughout. As Altitude Addicts
7:42
emphasizes, showcasing this capability
7:44
under real operational conditions is far
7:46
more persuasive than static displays.
7:50
Looking ahead, the strategic importance
7:52
of serial readiness extends well beyond
7:57
It reflects the maturation of Russia's
7:59
domestic engine industry and its ability
8:01
to field certified competitive civil
8:06
Markets such as India with growing
8:08
demand for cost-effective regional
8:10
turborops represent a long-term
8:14
The successful transition into serial
8:16
production also lays the groundwork for
8:18
future turborop and hybrid propulsion
8:22
The modular design, digital
8:24
architecture, and proven certification
8:26
pathway can be leveraged in next
8:31
In conclusion, the readiness of this
8:33
engine for serial production represents
8:35
a defining moment for UEC and Russia's
8:38
civil aviation sector. With
8:40
certification complete, operational
8:43
limits removed, thousands of flight
8:45
hours logged, and a full support
8:47
ecosystem in place. The program has
8:49
matured into a fully industrial product.
8:52
Its debut at Wings India 2026 integrated
8:58
signals confidence, capability and a
9:01
renewed intent to compete in the global
9:03
regional aviation market.
