0:01
for the first time the Russian United
0:03
engine Corporation ueec will exhibit a
0:06
fifth generation engine for tactical
0:08
fighter aircraft internationally at the
0:10
air show China in juhi 2024 according to
0:14
a statement from the ueec the main
0:16
attraction will be a full-size replica
0:18
of the enhanced al31 FN Series 5 engine
0:22
the aircraft's altitude and range
0:24
capabilities will be substantially
0:26
enhanced by the new generation power
0:30
first Deputy General director of rosc
0:32
said we offer our strategic Partners the
0:35
best solutions that not only enhance
0:37
combat Effectiveness but also reduce the
0:39
life cycle costs of engine operations
0:42
for the first time rosc will present an
0:45
updated lineup of the al31 F and FN
0:48
engine family at the international
0:50
exhibition in juhi including the fifth
0:52
series the new sm100 engine and an
0:56
entirely new fifth generation engine for
0:58
the most advanced operational tactical
1:00
aircraft building on the successful
1:02
lineage of the al31 F family developed
1:05
by solute and built in the EFA engine
1:08
building production plan the al31 FN
1:11
Series 5 engine represents a major boost
1:13
in Chinese Russian Aerospace
1:16
cooperation the latest version includes
1:18
many major improvements over its
1:20
predecessors particularly in the areas
1:23
of operational reliability and thrust
1:25
output the series 5 variant generates a
1:28
maximal Thrust of approximately 137 Kon
1:31
in After Burner mode which is a
1:33
substantial increase from the
1:35
132.5 Kon of the series 3 and the 123
1:40
Kon of the original al31 FN this
1:44
Improvement is achieved by refining the
1:46
aerodynamic design of the compressor
1:48
stages and improving the metalurgy of
1:50
the hot section the engine maintains the
1:53
fundamental two shaft configuration But
1:56
it includes Advanced single Crystal
1:58
turbine blades and and improved thermal
2:00
barrier Coatings which enable it to
2:03
operate at higher temperatures and
2:05
improve thermodynamic efficiency the
2:07
series 5 has made a major Improvement in
2:10
the time between overhauls which has now
2:12
reached 900 hours in contrast the series
2:16
3 had a time between overhauls of 750
2:19
hours and the original variant had 400
2:21
hours the increase is the result of more
2:24
Advanced Health monitoring systems and
2:27
improved durability of critical
2:28
components the engine's service life has
2:32
been increased to 2,000 hours which is a
2:35
significant improvement over previous
2:37
versions the series 5 boasts enhanced
2:39
fault detection and diagnostic
2:41
capabilities as the digital engine
2:43
control system has been extensively
2:46
modernized this system is especially
2:48
beneficial for sophisticated fighter
2:50
applications as it enables accurate
2:52
thrust management and more seamless
2:54
integration with modern
2:56
avionics the engine's modular design has
2:59
been kept but tweaked to simplify
3:01
maintenance and reduce disruption during
3:04
servicing the series 5 maintains
3:06
comparable external Dimensions to its
3:08
predecessors which guarantees
3:10
compatibility with extant airframes in
3:14
specifications the engine's dry weight
3:16
has been marginally reduced by the use
3:18
of Advanced Materials particularly in
3:21
non-critical structural components while
3:24
structural Integrity has been
3:25
preserved the host aircraft's
3:28
operational range has been increased by
3:30
approximately 2 to 3% in comparison to
3:33
the series 3 as a result of the specific
3:36
fuel consumption Improvement the al31 FN
3:40
is modified for Sid mounted installation
3:43
primarily developed for the Chinese J10
3:45
fighter countries that operate
3:46
chinese-made Fighters or are attempting
3:49
to upgrade existing al31 FN
3:52
installations may find the series 5 to
3:54
be an appealing option in terms of
3:57
export potential Nations seeking to
3:59
improve their Air Force capabilities
4:01
without the political complications
4:03
associated with Western power plants are
4:06
notably attracted to the engines
4:08
enhanced reliability and performance
4:10
metrics the principal Market consists of
4:13
current operators of Chinese J10
4:16
variants and potentially other
4:18
compatible platforms nevertheless the
4:20
export Market has been impacted by a
4:23
number of factors potential customer
4:25
bases are influenced by Western
4:26
sanctions and Export restrictions while
4:29
Market share is influenced by
4:31
competition from alternative power
4:32
plants such as Chinese ws10
4:36
variants furthermore export variants May
4:39
necessitate meticulous configuration to
4:42
address technology transfer concerns due
4:44
to the engines advanced technology
4:46
despite the fact that the al31 FN
4:49
cooperation is a distinctive aspect of
4:51
sinor Russian defense collaboration it
4:54
is crucial to acknowledge that China's
4:56
position has undergone a major change
4:58
China's critical requirement for
5:00
Dependable engines for its J10 fighter
5:03
program was the reason for the initial
5:05
al31 FN development as domestic engine
5:09
technology was not yet sufficiently
5:11
developed salute the Russian company
5:14
collaborated with China to customize the
5:16
al-31f design for single engine
5:19
applications such as the J10
5:21
nevertheless the relationship has
5:23
undergone a major shift as China's ws10
5:26
program has matured this family
5:28
particularly the Advanced ws10 B and
5:31
ws10 C variants are now claimed to have
5:34
achieved a level of reliability and
5:36
performance that renders them a viable
5:38
domestic alternative China has been
5:41
gradually replacing al31 FN engines with
5:44
ws10 variants throughout its J10 Fleet
5:47
with a particular emphasis on the more
5:49
recent j10c models this transition is
5:53
indicative of China's goal to establish
5:55
self-reliance in military Aviation this
5:58
ongoing collaboration on on the al31 FN
6:01
Series 5 appears to serve a number of
6:03
objectives for both Nations it serves as
6:06
a reliable secondary option for China
6:09
and contributes to preserving
6:10
technological diversity in their engine
6:12
supply chain additionally it provides
6:15
them with access to specific Russian
6:17
engine Technologies and Manufacturing
6:20
procedures it is a valuable export
6:22
program for Russia and contributes to
6:24
preserving Aerospace industry
6:26
relationships with China China is
6:28
unlikely to select the al31 FN Series 5
6:32
over the ws10 for new production
6:34
aircraft given the current trends the
6:37
ws10 has emerged as China's preferred
6:39
option for a variety of reasons
6:41
including the capacity to modify and
6:43
upgrade the engine without foreign
6:45
involvement reduced maintenance costs
6:48
and complete domestic control over the
6:51
supply chain furthermore recent reports
6:54
indicate that the most recent ws10
6:57
variants have attained performance
6:59
levels that are either equal to or
7:01
greater than those of the al31 FN Series
7:04
5 nevertheless China may continue to
7:07
acquire a limited number of al31 FN
7:10
Series 5 engines to maintain its current
7:12
deployments and conceivably for specific
7:15
applications in which a diverse engine
7:17
Supply is strategically advantageous the
7:20
relationship has transitioned from one
7:22
of dependency to one of strategic
7:25
cooperation in which China prioritizes
7:27
its domestic engine program while
7:29
maintaining the partnership now since
7:32
Chinese fighter aircraft barely sell and
7:34
Pakistan allegedly purchased ws10
7:36
engines will Russia ever sell the al31
