First Su-35S has flown
3 May saw the first productionstandard
advanced Sukhoi Su-35S
multirole fighter built under the
contract awarded by the Russian
Defence Ministry take off from
KnAAPO’s airfield for its maiden
flight. During the sortie, which
lasted an hour and a half, various
operating modes of the integrated
control system and powerplant of
the aircraft and its stability and
controllability were tested. The
engine, systems and avionics
operated without fault. Honoured
Test Pilot Sergey Bogdan was at
the controls. He had taken the
Su-35’s first flying prototype
(No. 901) to the air on 19 February
2008 and the second prototype,
Su-35-2 (No. 902), on 2 October
the same year.
According to a Sukhoi
spokesperson, the Su-35
preliminary trials have been
complete. At this stage, testers have
proven the stability, controllability,
powerplant performance and basic
characteristics of the avionics
28
suite, set by the requirements
specification. The tests had
involved two prototypes of the
export version of the plane before
the first aircraft for the Russian
customer has joined them. Now
the new fighter has been furnished
for the official trials. The results to
be produced by their first stage’s
results will yield a preliminary
report on the fighter’s compliance
with the customer’s basic
requirements and feasibility of its
full-rate production for subsequent
fielding with combat units of the
Russian Air Force.
The Su-35S-1’s acceptance tests
at KnAAPO’s airfield, which included
seven test sorties, had been
completed with success by mid-
May, after which the preparation
of the aircraft for handover to the
Defence Ministry for the official test
programme began. The programme
will be pursued mostly at the
Defence Ministry’s State Flight Test
Centre in Akhtubinsk where the
plane was ferried in late May.
The Su-35’s key features setting it
aside from other aircraft of the Su-27
family are a drastically innovative
avionics suite, wrapped around a
digital information management
system, and the cutting-edge
Tikhomirov-NIIP Irbis phased array
radar featuring the unique aerial target
acquisition range and enhanced
multiple-target simultaneous
tracking and engagement capability
(it tracks 30 and engages eight
aerial threats or four and two ground
targets respectively). The fighter is
powered by advanced, NPO Saturn
117S thrust vector control turbofan
engines. The Su-35 will pack a
wide range of up-to-date and future
weapons in all classes.
The contract for the development
and delivery of 48 Su-35S fighters
to RusAF by 2015 was signed in
August 2009. The production and
delivery are supposed to continue
afterwards.
