Export
deliveries are planned a short while thereafter. According
to the Russian 2007-2015 State Armaments Program, the Russian
Air Force is supposed to receive 116 new and 408 upgraded
aircraft for forward-deployed units. Furthermore, 156 new
and 372 modernized helicopters are required by the military's
strategy which is actively supported by President Vladimir
Putin.
About the Su-35
The aircraft is an advanced air superiority fighter based
on the Flanker (Su-27/30) platform, designed for the air/air
and air/ground roles.
Su-35 is considered to be one of the world's most advanced
fighters. The first prototype of the Su-35 was completed last
year (2007) at the Komsomolsk-on-Amur aviation Production
Association (KnAAPO) and was displayed in public for the first
time during the MAKS 2007 airshow.
The aircraft is equipped with two AL-37F (Saturn 117S) engines,
designed as modern derivatives of the AL-31F. The new engine
is developing 16% increase in power (14,500 kg maximum thrust)
it is fitted with independent (asymmetric) thrust vectored
nozzles, a new fan, high and low pressure turbines and improved
digital controls. The new engines are also more robust, offering
lower maintenance requirements and longer lifespan (up to
4,000 hours between main overhaul). The aircraft uses a triple-redundant
'fly by wire' flight control; compared to its predecessors,
Su-35 has an improved, integrated aerodynamic and propulsion
control enabling the flight control system to perform acceleration,
deceleration, roll, pitch and yaw utilizing thrust vectoring
in addition to classic aerodynamic control, alleviating the
need for the super-sized air-brake and canards used in previous
models. Availability of improved controls enabled the designers
to reduce the aircraft radar signature (radar cross section
RCS), particularly in head-on engagement pattern. (±
60° off axis). The aircraft is fitted with 12 hardpoints
for external loads weighing a total 8,000 kg.
Advanced Avionics:
The cockpit has a 'glass cockpit' design, utilizing two large
15" multi-function color LCD displays, a head-up display
and full HOTAS functionality. The main sensor is an X-band
E-Slavia radar allowing detection and tracking up to 30 air
targets while scanning a wide sector (track while scan). The
radar and fire control can simultaneously engage up to eight
targets. Production models will be fitted with the Tikhomirov
NIIP Irbis radar, capable of detecting and tracking aerial
targets with average radar cross-section of three square meters,
operating at ranges of up-to 400 km (216nm). Irbis offers
a wide area coverage of Irbis 70 to 120° with azimuth
resolution of (in 2 -2.5 times), increased range, and better
ECCM compared to its predecessors. The development of this
radar began in 2004. The system completed ground tests in
the lab and is preparing for the initial test flights on a
Su-30MK2 testbed.
May 2009: The third Su-35 prototype suffered an accident recently as the aircraft went off runway during a high speed taxy test at Dzyemgi airfield in Komsomolsk-on-Amur, Russia. The test-pilot Evgeny Frolov safely baled out. The aircraft has been planned to join two prototypes which are under testing and up to now have made more than 100 flights. Taking to account the successful testing of two flying prototypes the schedule of the Su-35 testing program stays invariable. The aircraft is due to enter service with the Russian air force in 2011and Russia is hopeful about its export prospects to Inida, Malaysia and Algeria.
The
first prototype of the Sukhoi Su-35 Flanker-E multi-role fighter
made its first flight on February 19, 2008. Flown by Sukhoi
test pilot Sergey Bogdan from Zhukovsky airfield near Moscow.
