EJ-2000 Has TVC, Then why would they not include that in the Euro fighter it self.

IF what you say is true then IAF has one more reason to go for the a TVC capable Typhoon which will use the same engine as the LCA-Mk1

AERO INDIA: Eurojet offering thrust-vectoring EJ200 for LCA
By Andrew Doyle

Eurojet is to propose a thrust-vectoring version of the Eurofighter Typhoon's EJ200 powerplant to meet India's requirement for up to 150 engines to equip the first squadrons of its indigenously developed Tejas light combat aircraft (LCA).

The Aeronautical Development Agency - which is leading development of the Tejas - is expected to issue a request for proposals in the next few weeks, pitching the EJ200 against General Electric's F414.

The Eurojet partner companies have been working on thrust vectoring nozzle technology for several years, lead by Spanish manufacturer ITP, which validated the concept during a series of bench tests. Eurofighter majority stakeholder EADS is equipping a cockpit simulator at its Manching facility to demonstrate the potential performance enhancements.

Thrust vectoring nozzle technology is being offered to the Eurofighter customer nations on the basis that it could significantly lower lifecycle costs by reducing fuel burn by "3-4% on an average mission" and extending the life of hot section parts, says Eurojet technical director Matt Price.

This is achieved by optimising nozzle shape throughout the flight envelope, and by eliminating the need for drag-inducing control surface deflections to trim the aircraft, particularly at supersonic speeds, where the aerodynamic centre moves aft, causing the nose to pitch down.

In addition, the technology can enhance agility, which could be of particular benefit to the Tejas as it is a delta-winged design that lacks canards.

EADS is leading the Eurofighter bid to win India's 126-aircraft medium multirole combat aircraft contest with the twin-engined Typhoon, and a deal to also equip the country's single-engined LCAs with the EJ200 would make the economics of establishing an in-country engine assembly line considerably more attractive.

The latest iteration of the Typhoon's flight-control system software has been designed to incorporate thrust-vectoring, and flight tests of the ITP thrust vectoring nozzle could begin within the next two years.

The flight-control system can be configured to use the thrust vectoring nozzle as an additional "control surface", boosting damage tolerance and reducing the risk of loss-of-control at low speeds, says Wolfgang Sterr, Eurojet engineering director EJ200/LCA. Furthermore, take-off distance for an aircraft such as the LCA could be reduced by around 20%, even in "hot and high" conditions, he adds.

Eurojet envisages a two-phase thrust vectoring nozzle flight-test programme, firstly using a twin-engine aircraft equipped with a single non-FCS-integrated thrust vectoring nozzle, followed by trials of the fully integrated system on both powerplants.

The TVC tech is new and wasn't on offer for EF so far, also some pilots say that the EF don't need it for maneuverability reasons. With the delta-canard design it already is one of the most agily fighters.
Yes the same engine for LCA could be an advantage for EF, or F18SH, because of more commonality. But on the other side the EF has a high unitcost and is sadly not fully developed and I doubt that IAF will take any aircraft that has a risk of delays (EF, Mig 35, or Gripen NG).

one simple question to you al-31f series engines have thrust vectoring so why RUSSIA dosent use them on its fighters...though the context is different ...E F is highly maneuverable with all the modern gizmos stuffed into it so it might be an option for future upgrades of eurofighter

Boeing's Super Hornet seeks export sale to launch 20% thrust upgrade

Boeing's Super Hornet seeks export sale to launch 20% thrust upgrade By Stephen Trimble

Boeing is seeking an international launch customer for a 20% higher thrust version of the General Electric F414 turbofan that powers the F/A-18E/F Super Hornet.

The F414 enhanced performance engine (EPE) includes an all new core and forward fan to dramatically increase the fighter's takeoff performance, said Bob Gower, Boeing vice president for F/A-18E/F.

The improvements would increase the F414 thrust rating from 22,000lbs to 26,600lbs(119KN). The baseline F414-GE-400, which also powers the Saab Gripen demonstration aircraft, is itself a 35% higher thrust version of the F404 and entered service with the Super Hornet fleet in 1998.

More recently, the US Navy, Boeing and GE have been developing durability improvements to reduce foreign object damage and specific fuel consumption, Gower told reporters participating in a Boeing media tour.

While the USN seeks a new engine core to make the F414 more durable, some international customers are interested in a new engine fan that enables higher thrust, Gower said.

"The 'enhanced durability engine' becomes the 'enhanced performance engine' when you put the fan on it,"(not a very major change) Gower said.

Although the core enhancements are already under contract with the USN, the programme is seeking an export customer to launch development of the F414 EPE, Gower said.

The international order would lead to follow-on sales for the USN, which would gradually replace its current inventory with the improved version, Gower said.

Several countries, including India, Brazil, Denmark, Greece and Kuwait, are considering the F/A-18E/F, with the Royal Australian Air Force already signed on as the first export customer. The RAAF has ordered 24 F/A-18E/Fs, including 12 provisioned to become EA-18G Growlers.

The improved thrust would likely be most welcomed among militaries operating in hot weather(thar desert), which reduces engine performance especially at a takeoff.

Despite the dramatic thrust increase, the EPE would not require enlarging the F/A-18E/F's engine inlets to enable increased air flow, Gower said.

"We are not modifying the mould line of the aircraft," Gower said. "The current inlet gives us enough [air] in-take."

Gower also said the EPE would require changing the number of compressor stages, but he did not elaborate.

The USN is also planning to steadily improve the F/A-18E/Fs sensors, electronic warfare system, connectivity and weapons load-out over the next decade, Gower said.

"The US government and Boeing and our suppliers," said Gower, "continue to invest in the platform because we see opportunities both domestically and internationally for the platform."

if F-414 EPE is in competition with ej-200 then EPE will definitely a clear winner in terms of thrust....

 

[Tejas-MkII]

As i said if EPE offered to IAF for LCA then we should go for it...

I know with EJ-200 we can get TOT,TVC,etc,.. but that is not sure and TVC may be in development phase..

And we cann't afford any kind of delay for LCA...

Best Configuration for IAF,in context of LCA and MMRCA,will be get EPE and buy rafale with full TOT (engine-core,aesa,flir,EW) and put these in LCA....

And parallely develop kaveri with the Tech we get from rafale...

Now ,imagine if that possible,will be,then LCA MkII will have thrust of about 120KN(EPE),AESA radar(RBE2 AA),FLIR,EW(may be spectra)....
Let the time taken for this config.. 2015,even then it is worth to wait for MkII...

 

[sudhir007]

can any body tell what are the price of these engine (RD-33MK, EJ200 & GE-414) and about life cycle cost plus fight hours

LiveFist - The Best of Indian Defence: EXCLUSIVE: LCA To Receive "HF" Designation Next Year

At this time next year, India's Light Combat Aircraft (LCA) Tejas, is near certain to receive a long due HF ("Hindustan Fighter") designation just ahead of initial operational clearance (IOC), after which the ubiquitous "LCA" tag will be dropped and serve only as its type description. A senior Air Force officer told me recently that while designating the fighter was scarcely a priority at this juncture, a file was in motion containing possible HF designations based on various parameters. HAL has been periodically questioned about why the LCA doesn't already have an HF tag. Stands to reason, actually. HAL's under development intermediate jet trainer, Sitara, already has its final designation HJT-36 (Hindustan Jet Trainer), and HAL's yet-t0-begin development ab-initio trainer already has the designation HTT-40 (Hindustan Turbo Trainer). So it isn't really clear why the Tejas hasn't received its rightful lineage designation, after all, it is India's first fighter jet after the Marut of the sixties, which had its own venerable designation, HF-24.

ONLY IF THEY worry less abotu taking credit - and developing the jet and making it induction able in our defence.

To avoid lot of hurdles & failures from past memory's HAL may selected HF, on my view HF71 seems to be good as per Numerology, also to remember 1971. WE need tejas mk2 version should be ready before the deadline. so HAL should not waste long time in the name of selecting engines . We wish IAF should have large numbers of sqn's in Tejus mark 2 version .

 

[blackbriar]

Yet, your own air force dont want it. Far ahead of getting operational is probably correct in that context.



They hated the aircraft thats why they spent 48% of Research & Development.

that says more abt the strict quality standards of the airforce rather than the plane.the pakistani airforce is in a state where it is ready to take whatever junk is being given to it.jf-17..

LCA no more???

So then, the HF-X Tejas, it shall be

good to see the arjun sticky has been removed. it is a good time to remove this LCA propaganda thread from the sticky list.

have a look at our L-15. can anyone tell me why LCA is better than this aircraft?

Have you ever considered a career in Chinese propaganda. If not you are wasting your skills doing anything else.

you should apply as soon as possible you no doubt fit in perfectly.

You are exactly the kind of person that would have made Chairman Mao proud.
Unquestionable, faith and belief with the CCP

because I presented a twin engine trainer better than your joking LCA?

face it, we have more interesting stuff to come in the next few years.

Presenting a unwavering unspecific Argument,
Seriously you need to work for Chinese Propaganda, you already know most of the basics.

Don't worry about the LCA or should i say HF. IF it is as useless as you say you shouldn't have to give it a single thought.

Let the Indians discuss this aircraft in peace.

Another Russian copy of Yak-130, shame on you shchinese to post this on LCA thread.
