Citat:Kako malo kad avion jos uopste nije gotov nego ima tek dva prva prototipa za aerodinamiku.
Moj komentar se odnosio na procene Rusa a smatram da se to sto oni govore nece obistiniti.
Treci prototip T-50 treba da bude gotov krajem ove godine, a jos 10 aviona do 2015. Posle toga je navodno planirano jpos 60 aviona za 5 godina. Dakle 12 aviona godisnje.
F-22A je poleteo 1997. a uveden u naoruzanje 2003. Za 8 godina proizveli su 187 aviona.

su47berkut ::Су34 је раскршћу,јер постоје планоови о његовој модернизацији нови мотор,нови радар и још неке ствари.
Ja nikako ne mogu da se otmem utisku da je su-34 stigao sa ogromnim zakašnjenjem u smislu tehnološke evolucije(naravno da je svaki novi avion ruskoj avijaciji bio preko potreban i u tom smislu je o.k) ali ako je vest tačna , zaista me ni malo ne iznenadjuje, jer kao laki nadzvučni bombarder , mislim da nema onu tehnološku "oštrinu"(Teh-edge)kakvu bi moderni avion takve namene morao imati, tu pre svega mislim na spomenutu elktroniku(naročiti jamer-i)I radar koji mora biti superioran u odnosu na većinu današnjih lovaca 4-te i 4+ generacije, i najbolju moguću fuziju senzora za gadjanje ciljeva na zemlji, njemu bi trebao uredjaj poput JSF-ovog DAS-A, a to su-34 danas nema.
Izvinjavam za mali OT

Ma pusti ti berkuta. Su-34 kakav je sada je bolji od svega sto imaju (za namene za koje je predvidjen). Te fore "ne pravi ih dosta jer hoce da prave jos modernije" neka prodaje on nekom drugom.

Tacno!
Za ono sto je predvidjen SU-34 nema konkurente ni u zapadnim masinama.
Nije cudno sto je ruski general izjavio da im je to mozda i najbitniji avion, jer je "pravi radni konj", sto je i dokazao u ceceniji i gruziji.
Dakle jedna usko specijalizovana i sofisticirana masina, sa svim sto joj je potrebno da bi unistila ciljeve na zemlji i moru.

Communication system for 5th Gen aircraft:
Citat:PROMISING GROWTH PATHS FOR AIRBORNE COMMUNICATIONS SYSTEMS
Military Parade 2011
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.
