PICTURE: PAK-FA flameout embarrasses Sukhoi
By Vladimir Karnozov

Russia's MAKS 2011 air show closed with an embarrassment for Sukhoi, when the pilot of its second prototype PAK-FA/T-50 was forced to abort a take-off run after two bursts of flame erupted from the fifth-generation fighter's starboard engine.

The incident happened in front of about 200,000 visitors, who had gathered at Ramenskoye air base near Moscow on 21 August to watch a flying display.

Also referred to as T-50-2, or Side 52, the aircraft was forced to stop from a speed of around 100km/h, with Sukhoi test pilot Sergei Bogdan using wheel brakes and also deploying a brake parachute.

It stopped well short of the aerodrome fence, thanks to the 5,000m (16,400ft) length of the runway.

Sukhoi said the aircraft had suffered a technical malfunction but no damage, and that its pilot had acted "in accordance with manuals".

The company later attributed the issue to a "malfunctioning fuel supply system" and to the NPO Saturn Item 117 engine's full-authority digital engine control system.

To further Sukhoi's embarrassment, immediately after the incident the show's organisers promised the public that the first PAK-FA prototype would fly instead. This failed to happen, with the aircraft believed to have been sent for maintenance shortly after performing in front of Russian prime minister Vladimir Putin on 17 August.

Comment ils ont pu quand même négliger de vérifier méticuleusement et de fond en comble leurs moteurs avant d'envoyer leur f éraille parader devant 200 000 personnes et toutes les délégations militaires de la planète....... Les russes pris en flagrant délit de manque de sérieux, c'est honteux

moi je dis dommage qu´il a freiné,on aurai eu une belle flankerisation du nouveau né a la tradition russe
flankerisation selon le dictionnaire aeronautique https://far-maroc.forumpro.fr/t250p345-photos-d-avions-militaires#187561

Encore une fois les avis pré-montés .... qui guète les grains de sables russe et honore les perles occidentales.

s´il se demande sur la defaillance du moteur avant show -avouée par le constructeur meme- alors ce n´est pas "avis monté" ou prejugé,c´est la réalité.
meme les prejugés,ca vient pas de null part

According to Fedorov, this was due to a malfunctioning sensor which
began feeding "erroneous data" to the airplane's control system.

T-50: The Fifth-Generation Fighter's Sensors

With the T-50 fifth-generation fighter making its MAKS air show debut, the Russian industry also has provided additional insight into elements that will make up the aircraft.

Some components have been been shown before, but the collection of the subsystems on display is unusual.

First is a mock-up of the active, electronically scanned array radar:


The fighter also is due to feature embedded L-band antennas:



Also on show were models of the T-50's two IRST sensors—here the frontal IRST (or KS-B), with coating aimed at reducing its radar return:



Second is the rear-looking sensor, the KS-O:



And lastly, sensors mounted in the aircraft structure:



Industry officials say the Article 101KS targeting pod also is
T-50-bound, although the device is hardly stealthy and the fighter may
yet feature a different approach.

PROMISING GROWTH PATHS FOR AIRBORNE COMMUNICATIONS SYSTEMS

Author: Alexei Komyakov, Konstantin Voytkevich

Alexei Komyakov - director general of FSUE NPP Polyot.

Konstantin Voytkevich - director for research, deputy designer general

FSUE NPP Polyot (Nizhny Novgorod) is a leading Russian developer and manufacturer of aircraft radio communications equipment and has the status of the Federal Research and Production Center. It conducts R&D, carries out full-scale production and upgrades its earlier products.

Standard radio communications systems for new Gen 4++ and 5 aircraft occupy an important role in Polyot's R&D efforts. Equipping modern combat aircraft systems with the latest electronics helps integrate them into the Air Force's information management system, which provides the crew with complete information for task accomplishment in real time.

NPP Polyot develops communications systems using the integrated modular avionics (IMA) technology. Technically, the IMA computer system is defined as a set consisting of crates that comprise a set of common modules and communicate via a unified digital network. To achieve maximum effect from implementing the IMA technology, a comprehensive approach to building an avionics suite on an aircraft is required. The crates ensure the installation of modules, their communication with each other, and heat removal. Cooperation between modules is done via a motherboard carrying power supply circuits, low-speed interfaces, high-speed serial interface circuit and a PCI bus.

The performance level of advanced communications systems is characterized by high quality of data and voice transmission, improved consumer properties, compatibility with avionics, guaranteed reliability and broad applications, practical implementation of the software-defined radio concept. All non-unified communication functions are software- rather than hardware-implemented, allowing their adaptation to future changes in requirements without costly upgrades.

The software-defined radios use modern integrated microelectronics, open architecture for operation in a wide frequency range, from 2 MHz to 6 GHz, provide data and voice transmission.

The novelty of the developed systems lies in the software implementation of the maximum possible number of required functions and the use of several basic technologies: network interfaces and the user interface, opportunities for remote booting and upgrading the whole software and the necessary code to configure turn-on of all equipment. Accessibility of all system elements providing their reconfiguration and setup on the part of the network, the use of versatile hardware platforms, allowing software implementation of the most diverse functions on them, as well as software-based data security methods are of great importance.

The design of the system's equipment corresponds to the standard series defined by state standards and allows quickly building up its functionality.

All of these solutions and technologies have been implemented in NPP Polyot-developed S-111 communications system for a future Gen 5 fighter. Its main features are as follows:

- fully digital architecture allowing a significant reduction in the system weight and dimensions;

- improved communications quality and reliability;

- use of modular design makes it possible to increase the number of channels and scope of functions;

- re-programmability, i.e., the capability to store and use different algorithms without hardware modifications;

- a single internal information network reducing the number and range of interfaces used;

- software implementation of most of the functions, modulation types and emission classes together with the possibility of rapidly changing the types of operation;

- use of the Baget 2.0 standard operating system simplifying the development and improvement of the system's software modules;

- software implementation of operation modes with increased jamming immunity;

- low power consumption;

- operation via high-speed channels at up to 40 Mbps with the capability to transmit different types of information (video, data, voice).

Transceiver modules installed in the S-111 system enable operation in the HF, VHF/UHF, SHF bands: provide communication in a unified communications, navigation, identification and data transmission system and in satellite communication channels. It is possible to include radios operating in other bands in the system.

As part of a fifth-generation fighter, the S-111 system has ensured the successful accomplishment of over 60 test flights.

Versions of the system are planned to be installed on different objects operated by the Russian Ministry of Defense and foreign customers. Work is underway to adapt the system to the helicopters, long-range and military transport aircraft as well as to ground communications centers.

il est magnifique beaucoup plus beau que le raptor à mon goût

Declassified: 'Russian stealth' T-50 Fighter debut

Visitors to the MAKS 2011 air show have been treated to the first public performance of the declassified Sukhoi advanced fifth-generation frontline fighter jet T-50.

­The Russian PAK FA stealth fighter aka T-50 is intended to replace the SU-27 fighter and challenge the American F-22 Raptor stealth jet.

This long-awaited combat fighter is a Russia-India joint development, with India being Russia's largest export market. Eventually, Russia wants to equip its air force with up to 200 T-50s.

­When production begins – which could be as early as 2015 – it will become the Russian Air Force's first stealth aircraft, equipped with technology making it almost undetectable to radars.

It will also be able to fly at supersonic speeds and pull maneuvers that were impossible for older jets.

C'est AL-41F1A qui se base sur le Al31F le AL-41F utilise un tout nouveau système et qui sera un vrai moteur d'avion 'stealth' (croisant les doigts )

dans la video c´est ecrit AL-41F1(article 117),et je sais que ce moteur est l´amelioration du AL-31F du SU27 beneficiant d´un diametre de soufflance accru,de nouvelles turbines hautee et basse pression,d´une chambre de combustion ameliorée et d´un nouveau FADEC.
ce meme AL-41F1 devrait equiper le T50 au moins jusqu´en 2020.

Le chasseur russe de 5e génération effectue son 100e vol

Le chasseur russe de 5e génération Sukhoi T-50 (PAK-FA) a effectué jeudi son 100e vol d'essai, a annoncé à Moscou le service de presse de l'avionneur Sukhoi.

"Le centième vol s'est déroulé dans le cadre des essais en vol de l'avion de cinquième génération", a indiqué la société Sukhoi dans un communiqué.

Deux T-50 participent aux essais en vol lancés le 29 janvier 2010 à Komsomolsk-sur-l'Amour (Extrême-Orient russe). Le deuxième avion s'est joint aux tests début mars.

Le chasseur T-50 a été présenté au public au Salon aérospatial international MAKS-2011 à Joukovski (région de Moscou), en août dernier.

Le chasseur de 5e génération T-50 est développé en Russie depuis les années 1990. Il s'agit d'un appareil tactique alliant les caractéristiques d'un avion de frappe et d'un chasseur classique.

Invisible pour les radars ennemis, il sera équipé d'un nouveau poste de navigation de bord et d'un système de défense automatisé. Le T-50 est équipé d'une avionique foncièrement nouvelle intégrant une fonction de "pilotage électronique" et un radar ultramoderne, ce qui permet au pilote de se concentrer uniquement sur la mission de combat. Les équipements de bord assurent un échange de données en temps réel aussi bien avec les systèmes de commande au sol qu'avec les autres avions du groupe aérien.

Le T-50 sera fourni à l'armée russe en 2016.
