0:01
developed over a period of approximately
0:03
15 years the t204 was the last model in
0:07
the Soviet medium Hall passenger
0:08
aircraft design during this period the
0:11
designer's perception of what it should
0:13
be underwent significant changes on
0:15
numerous occasions the aircraft was
0:18
designed to supersede the TU 134 and Tu
0:22
154 the previous generation of medium
0:25
Hall tupv airliners development started
0:30
the new airliner was intended to be
0:32
twice as fuel efficient as its
0:34
predecessors as well as more comfortable
0:36
safer and allseason the first concept of
0:39
design intended for the new aircraft to
0:41
be an enlarged version of the
0:43
t134 with engines located in the rear
0:46
section and an increased fuselage
0:48
diameter to accommodate 150 to 180
0:52
passengers the selection of this design
0:55
may have been influenced by Leonid
0:56
selakov the project leader who had
0:59
previously served d as the principal
1:00
designer of the smaller tushka or
1:04
t134 the designers intended to shorten
1:07
the development Time by incorporating
1:09
numerous advancements from the TU 134
1:12
and 154 series The Project also included
1:15
modernized nk8 engines which are the
1:18
same as those used on the TU14 the
1:21
global aviation industry was
1:23
progressively transitioning away from
1:25
rear engine aircraft as the project was
1:27
in progress the inst installation of jet
1:30
engines beneath the wings was becoming
1:32
more prevalent upon reconsidering its
1:35
approach the tupv design Bureau
1:37
introduced A New Concept in
1:39
1975 the updated design bore a striking
1:43
resemblance to an Airbus with a fuselage
1:45
length that was comparable to the TU
1:48
154 however the diameter was
1:50
considerably increased measuring 5 m as
1:53
opposed to the previous models 3.8 M the
1:57
most evident modification was the engine
1:59
placement which was similar to The New
2:01
American airliners McDonald Douglas md10
2:04
and Lockheed l1011 TriStar the engines
2:08
were positioned under each wing and in
2:10
the tail a full-scale mockup of the
2:14
t204 was built in 1982 the
2:18
tu24 was configured with three engines
2:21
but it was only available as a
2:22
full-scale model after abandoning
2:25
unification with the TU 154 the
2:28
designers started investing tigating
2:30
multiple design variations they
2:32
entertained the possibility of using
2:34
both the most recent high- bypass jet
2:36
engines and prop fan engines neither of
2:39
which were produced in the Soviet Union
2:41
at the time the fuselage landing gear
2:43
and principal systems had been
2:45
determined by the tupv design Bureau in
2:48
1980s the fuselage capacity was
2:51
increased to accommodate 208
2:54
passengers nevertheless there were
2:56
disputes regarding the aircraft's power
2:58
plant manufact ufacturers such as Boeing
3:01
and Airbus were developing twin engine
3:02
airliners including the Boeing 757 and
3:06
767 and the Airbus a300 by the time the
3:10
trend for three engine airliners had
3:12
passed the tupv team also elected to
3:15
investigate this concept which they
3:19
224200 a new engine the D90 was
3:22
developed by the team of chief designer
3:24
Pavo solovov for this iteration work on
3:27
the 3 engine 300 variant continued in
3:29
the interim Chief designers alexe
3:32
tupolev and solovov himself supported
3:34
this version as they were of the opinion
3:37
that it would be impossible to develop a
3:39
jet engine of sufficient power in light
3:42
of the current condition of Soviet
3:44
industry the estimated thrust of 12 to
3:46
14 tons per engine was determined to be
3:49
inadequate for a twin engine design
3:52
nevertheless Leonid selakov was adamant
3:56
about the twin engine configuration
3:58
selakov resigned in transferred the
4:00
project to a new chief designer as a
4:02
result of the conflict nevertheless his
4:05
argument was ultimately validated the
4:07
d90s propulsion was successfully
4:09
increased to 16 tons and the twin engine
4:12
design was selected as the final
4:15
configuration the tu24 entered flight
4:18
testing in this configuration and it
4:20
made history in Russian
4:22
Aviation the ps90 engine is the current
4:25
name for the D90 engine the First Flight
4:27
of the tupv tu04 happened happened on
4:30
January 2nd 1989 the first model was
4:33
equipped with solov ps90 turbofan
4:36
engines and subsequently underwent a
4:38
series of modifications such as the SM
4:41
and 300 there are many variants of the
4:43
aircraft Each of which is tailored to
4:45
address specific operational
4:47
requirements the t204 is the basic
4:51
passenger model and the designation C is
4:54
the cargo variant of this base model the
4:57
t2400 was the first pass passenger
5:00
version to be certified in 1995 and is
5:03
powered by Russian ps90 engines a
5:06
variant that is heavier and has a higher
5:08
fuel capacity is the 200 version which
5:11
is designed to provide an extended range
5:14
furthermore the 100 C and 200C are cargo
5:18
versions of these variants that are
5:20
equipped with a forward main deck
5:22
Freight door upgraded and specialized
5:24
variants are also included in the t204
5:27
family the SM or the cm is a modernized
5:31
version that features upgraded avionics
5:33
ps90 A2 engines and improved passenger
5:37
amenities additionally it can operate
5:40
with two pilots it was intended to
5:42
comply with International standards
5:44
however production was restricted a
5:46
shortened fuselage version of the 300
5:48
version with an extended range is
5:50
designed for Long Haul operations
5:52
whereas the 500 version is a short Hall
5:55
variant that is optimized for shorter
5:58
routes and is based on on the 300
6:00
version tupal have developed westernized
6:03
variants to appeal to non-russian
6:05
markets the 120 and 220 versions are
6:08
fitted with Rolls-Royce rb211 engines
6:12
the 120c and 220c are freighter versions
6:15
of these westernized variants the t204
6:19
platform has been modified to
6:21
accommodate various operational
6:22
requirements and International Market
6:24
demands as evidenced by these variants
6:27
the tu2 04s M the most recent
6:31
significant iteration of the
6:33
t204 performed its inaugural flight in
6:36
December 2010 it failed to Garner
6:38
widespread orders despite its upgrades
6:41
which included improved avionics and two
6:43
pilot operation production records
6:45
indicate that the last t204 was built in
6:48
July 2021 however a few aircraft are
6:52
still operational or stored as part of
6:54
its strategy to replace Western aircraft
6:56
in the wake of sanctions Russia is
6:58
presently focusing on the production of
7:01
t214 a derivative of the
7:04
tu24 nevertheless the aircraft has been
7:07
mainly replaced by more recent designs
