Korea turns to Israeli contractor for KF-X jet radar: source

Citat:South Korea has formally decided to receive some technology support from Israel for the development of an advanced radar system in its KF-X fighter jet program, Seoul's arms procurement agency said Tuesday.
The state-run Agency for Defense Development signed a contract with an Israeli defense firm on testing an active electronically scanned array radar being developed by a South Korean company, according to the Defense Acquisition Program Administration.
"It's about technology support related to the operation test of a prototype radar, not the development itself," the DAPA said.
The agency would not reveal the value of the contract apparently with Elta, while an industry official said it's worth around 40 billion won ($35.5 million).
It requires sophisticated technology to test an AESA radar system and integrate it with aircraft.

South Korea's KF-X Grows Considerably In Development

Citat:The Korea Aerospace Industries (KAI) KF-X fighter keeps growing. What began as a concept design as big as the Eurofighter Typhoon has repeatedly gained length and wingspan and is now likely to be heavier than that earlier aircraft. The indigenous fighter will have a two-seat version, developers have confirmed, following years of depictions of it with just one seat. And the type will be equipped with MBDA Meteor and Diehl IRIS-T air-to-air missiles

Taj avion prema fotografijama modela neće biti 5 generacije jer nema unutrašnjeg spremnika za bombe i drugo naoružanje. Vanjskim pilonima i naoružanjem na njima nemože mnogo smanjiti radarski odraz. Neznam koja vajda uništiti idealnu aerodinamiku a da nisi uradio "stealth" avion? Ok biće "stealth" bez da nosi naoružanje.

Trebalo bi popraviti naslov teme i izbaciti reči "lovac pete generacije" da ne zavarava forumaše.

@jazbar
Pošto imaju podršku Amerike i Japana, a sami će kupiti F-35, ovo je savršen avion za njih. Ekonomično rešenje sa drastično umanjenim radarskim odrazom.

Zanimljivo je ovo staklo ispred same antene koja inace ima zastitni poklopac koliko vidim tako da staklo ne sluzi da stiti module od nekih ostecenja vrlo moguce da je staklo ustvari plazma ekran za smanjenje odraza same antene.

Bilo o tome ranije, ovo je faza jedan, faza dva ce imati spremista ali ni tu fazu oni ne smatraju steltom tek bi faza tri trebala da bude pravi stelt. Inace faza 1 i 2 su prilicno slicne sto se tice izmena.

Citat:Hanwha Systems is working on the fighter’s targeting pod, no doubt with much support from ADD. The country has not made such a device before, but it has technology from naval infrared sensors. The key challenge involves reducing size and weight, says a project manager on the supplier side of the fighter program. ADD also has experience in developing a reconnaissance pod.

The choice of a pod, in contrast to the Lockheed Martin F-35’s internal system, was probably driven by ease of integration and a lack of space in the smaller South Korean aircraft. Using a pod implies a planned second, stealthy version of the KF-X will not have low radar signature in the surface-to-air role. The weapon bay intended for the second version is not likely to accommodate a large internal air-to-surface load, anyway.

By contrast, the electronic warfare (EW) system that LIG Nex1 is working on will be internal. The technology comes in part from the ALQ-200 EW pod used by South Korean F-16s and F-4s, says another supplier-side source.

The same company is supplying the flight-control computer, radar altimeter and flight data recorder. All of these are derived from systems developed for the Korean Air Lines Co. MUAV surveillance drone.

The predecessor program most relevant to KF-X is the one that developed the T-50 trainer and its light-attack versions. The T-50 used the conventional aeronautics hydraulic pressure of 3,000 psi (21,000 kPa). KAI wanted consideration of the more modern figure of 5,000 psi, which should have cut weight and bulk. But familiarity with 3,000-psi technology and the availability of testing equipment led to the decision to stay at that level, says the second supplier-side source. Spanish hydraulics specialist CESA will assist in hydraulics development, as well as in designing the arrestor hook.

Since the KF-X is bigger and carries more systems, notably a radar, electrical capacity is much greater than in the T-50. Power in the LIG Nex1 system is up more than 50%.

The head-up display (HUD) will be manufactured under license from BAE Systems by LIG Nex1, which will have to design the interface with the rest of the avionics. BAE also made the less advanced HUD in the T-50.

KAI chose Heroux-Devtek and Hanwha to develop the landing gear. Most of the work will surely be done by the experienced Canadian company, although this has not been officially announced.

The KF-X’s engine is the General Electric F414. Hanwha’s propulsion division, Hanwha Techwin, will make parts and, according to the companies’ joint statement, lead integration and installation. Again, the foreign manufacturer is likely to play a larger role than is acknowledged.
