boss! i dont have permission to give exact configuration! sorry!

Brand new LCA-Tejas website

http://www.lca-tejas.org/

I think it just updated website not a brand new one. and even the updates need to be completed , the test flight numbers is 1091 , whereas the actual is 1141 as on date.

Is LCA going to be ready in two years? I heard MiG-21s are to be withdrawn in that time.

ioc for lca is in late 2010 .........engine related issues are yet to be sorted out.

DASH Helmet Mounted Display

helmet mounted display and sight system, already operating with over 500 aircraft such as F-15, F-18, LCA and MiG-21. DASH is measuring the pilot's line of sight (LOS), slaving missiles and sensors to the target, DASH also brings displays to the pilot's eye-level and informs the pilot of target location, while integrating all modes of operation with Hands On Throttle And Stick (HOTAS) controls.

Never asked for it.

Nevertheless, MC is not a big secret. Sooner or later they will reveal it.

p2prada , any deatils about OAC?

P2P the CIP of F22 also uses PowerPC chips

The F/A-22 Common Integrated Processor is the first fully integrated avionics processing system.

Developed as “the brain” of the Air Force's F/A-22 avionics system, the F/A-22 CIP packs the processing punch of two Cray supercomputers to represent a breakthrough in modern processing systems. The modular, fault-tolerant F/A-22 CIP configuration employs up to 66 PowerPC and i960-based signal and data processor modules, all interconnected for efficient sharing of computational tasks. Information is fused into a clear, concise picture of the combat situation. Such computing means dramatic reduction in pilot workload, allowing the pilot to focus on winning air-to-air combat and returning unscathed from battle.

The F/A-22 CIP features an advanced high-speed computer that conforms to the Joint Integrated Avionics Working Group (JIAWG) and Pave Pillar guidelines. Key technologies include fiber optic external interfaces to enable high-speed data transfer, ultra high density packaging to meet sizing constraints, and a real-time operating system to support secure information handoff. Using a heterogeneous, switch-based architecture, the F/A-22 CIP hosts mission processing and sensor fusion; radar signal and data processing; integrated electronic warfare processing; and integrated communications, navigation, and identification processing applications.

The F/A-22 CIP's planned evolution includes two low risk upgrades. The first, the CIP 2000 program, currently contracted through the U.S. Air Force and Lockheed Martin, will further reduce the CIP's already attractive price. The second upgrade improves the CIP's impressive processing performance to meet mission growth requirements.

OAC or OACE is actually Open Architecture Computing Environment. IAF requested for OAC as a requirement. This will be connected to a CIP(Common Integrated Processor). The CIP or MC will handle more functions than the older MC. OAC allows standardization of equipment. It will be as good as plug and play. This will make avionics upgrades easy and cost effective.

As to what the processor core is, I have no idea. Venkat seems to know, perhaps he will be able to tell us in time.

 

[p2prada]

The F-22s CIP is way out of our league and also not required for the LCA
The F-22s CIP was mainly developed for the AESA radar which requires more than half the programming in the F-22.

Even IBMs Blue Gene Supercomputer is based on IBMs PowerPC 400 series. Hopefully the rumors are true for the LCA. Especially considering the LCA Mk2 will have AESA.

Tejas may skip operational clearance deadline

Ravi Sharma

BANGALORE: Worried over the pace of the indigenous Light Combat Aircraft (LCA) Tejas programme, the Indian Air Force has suggested that the deadline for the fighter’s initial operational clearance (IOC) be postponed.

According to the latest schedules, the IOC is December 2010. But with a number of issues dogging the design and development of the fighter, the postponement was suggested during last week’s ‘monthly review meeting.’ Senior officials from the designers, the Aeronautical Development Agency (ADA), the IAF (including the newly appointed Deputy Chief of Air Staff Air Marshal N.V. Tyagi) and the manufacturer, Hindustan Aeronautics, were present.

Highly placed sources told The Hindu that the software integration of crucial equipment like the Israeli-built multimode radar (MMR) with the aircraft was yet to be completed. The lack of a radar meant that crucial points on the flight envelope were yet to be tested.

The ADA has still not provided HAL with the digital flight control computer and air data computers which have to be integrated into the LCA programme’s Limited Series Production 3 (LSP3) aircraft.

The new LSP3, which was scheduled to make its first flight in June 2008, is now expected to do so only in September.

Both the IAF and the ADA have bemoaned the low sortie generation by HAL. Just 11 sorties were undertaken in April, 24 in May and 23 in June. Officials claim that a minimum run rate of 30 sorties a month is required to meet the present IOC deadline. With this in mind, a plan to prepare two aircraft for flying in the forenoon and one in the afternoon was worked out. But this has not fructified.

HAL officials, however, deny that sortie generation is the primary reason behind the delays. “With two aircraft withdrawn from the flight test programme, we have just five aircraft to generate sorties,” said an official.

“And even the available aircraft are not fully fitted to undertake the flights that are required. We have even painted LSP3 in its new colour [grey] and are ready. LSP4 will have its ground run before the end of July and the fuselages for LSP5 and LSP6 are ready. On six occasions in June while the aircraft was prepared and the weather good, there were no pilots.”

Officials said the IAF was aware of the shortage of test pilots at the National Flight Test Centre (the LCA is flown exclusively by these pilots) and was looking to increase their number.

pv5 is not mentioned in this article which was supposed to be under going ground taxi trails .........................

I don't think the n-tejas is going anywhere soon. obviously there is lot more needed for one heavy undercarriage and a powerful engine with 100 kn of thrust.

Indian Engine RFP Expected This Week

BY :Aviationweek

The long-awaited request for proposals (RFP) to provide 99-125 engines for the Indian Air Force’s Tejas Light Combat Aircraft is expected to be released this week.

Proposals for the two candidate engines — GE’s F414 and Eurojet’s EJ200 — will be due by Oct. 12 if the RFP is released on July 17.

In October 2007, Eurojet signed a nondisclosure agreement with the Bangalore-based Aeronautical Development Agency (ADA), which is developing the LCA and evaluating alternatives to the GE F404 engine powering the Tejas prototypes and initial production aircraft.

A senior official of Eurojet says it will transfer data under the agreement to India’s Gas Turbine Research Establishment (GTRE), which is responsible for developing the indigenous Kaveri engine planned for the LCA.

“We have interest in doing more with GTRE. However, we shall wait for milestones to be reached,” an official says. “Once you have a ticket to ride….synergies [with other projects] are quite natural, though the customer might think different.”

With severe delays to the Kaveri program and performance limitations with the initial LCA, the Indian air force is keen to push ahead with an off-the-shelf engine acquisition. Former air force chief Fali Homi Major said early this year: “We need five squadrons of the Mk2 LCAs. When integrated with the new engines, the LCA Mk2 should fly in 2013.”

The GE414 powers the Boeing F/A-18E/F and Saab Gripen NG, while the EJ200 powers the Eurofighter Typhoon. All three aircraft are contenders in India’s 126-aircraft multirole fighter competition now under way.

“Our engine needs minimum changes and will not delay the LCA,” the Eurojet official said.

both are good engines, the GE 414 G has a higher thrust of 98KN than the EJ2000 92KN and the GE can be increased to 130KN as growth potential, GE414 EPE is now on offer for us and has 118KN thrust, its also a low risk, lower cost option, GE knows the LCA, EJ is good has better fuel burn and growth potential out to 100KN+ but requires time, money effort and this could delay the process. Plus this decision i bet will be tied to the MRCA as well. IF SH wins we'll go for the same GE EPE engine on the LCA as well, will certainly make the LCA super cruise with full combat load at a very good speed.

But EJ-2000 Can be installed without much modifications to the Aircraft.....Putting a GE-414 will delay The project
