LCA Tejas Engines failed during high-altitude trials in Leh

[OrionHunter]

Browne said delays do take place in a development project such as the LCA. "Recently we went for high-altitude trials. The engine (of LCA) did not work at that altitude because it is a different cup of tea. So, the LCA will have to be modified. It has to do the retrials," he said.

Huh? Retrials??? WTF were they doing for the past 20 years? Poodle faking I guess!

 

[Arav_Rana]

LCA faced same technical issues which were faced in SU-30, MMRCA applicant. If yes then WTF they didn't try to fix it before testing. 1st testing was in 2001 and it took them 12 years to test in high altitude.

Seriously man DRDO ne LCA project ka mazak bana kar rakh diya hai. Yeah to band kar do project ko, daily ki notanki to band ho kam se kam.

 

[帅的一匹]

Although I should out of this , but I've to say HAL is moving like a snail.

 

[True pakistani 22]

India already knows the problem and the problem is with US engines and fuel mix, this problem can be rectified quickly.

whatever problem is
need to Fix

Indian Govt should Take action against DRDO
Look at NESCOM har Project Waqat per ready

Tejas Winter Trials At Leh Last Month






So in Leh it flew without engine...

Indian PS technique has improved.

Really? every project is ready , what complicated project they have taken? can name few projects?

The tejas might be proving its good enough, since it might be doing air start testing. Since it is a single-engine fighter it might require so. This proves the LCA's reliability.

The F-35 (also a single-engine fighter) has also did this.

Its already been done thats why IOC was given........

 

[faithfulguy]

i think we should scrap this project and change it into trainer aircraft.Now 3 more years?

Something is wrong with IAF or with HAL.if its HAL then i m doubtful about their capacity to absorb rafale .

and they will keep inducting rafales till 2030 with current pace.


Scrap this project and save the assembly line for rafales and increase the direct import of rafales to atleast 50.

Thank you, Thank you, Thank you. I've been saying this for a long time and I received only harsh response as an attack on India.

Very disappointed .... LCA Tejas has made us a subject of ridicule world wide. It is high time for government of India to hold people accountable..as billions of tax payers money have been wasted on this project. The mammoth funds consumed by this project has yield nothing but embarrassment, disappointment, and delays.

 

[faithfulguy]

As for 2015 FOC, FINGERS CROSSED

I hope India get this plane ready soon. Even if it takes up to the year 2050 and its obsolete when its inducted, India should build this plane after all these years of working on it.

Correction. LCA has provided entertainment to the world for ages. It has done so well. It's only fitting that it continues to perform its entertaining duty much longer. Good job, Indians.

Probably it did not lift-off for some load parameters. We all know Indian defence journalism sucks big time.

What might be the problems? Less thrust generated by the engine during take off because of lower air density?

High altitude = less oxygen.

Interesting statement by the fact that it is an US engine that had the problems here, not the Indian fighter!


On topic, it is not a big deal and not surprising, since the MMRCAs with GE engines had the same problems too and needed to be "modified" to finish the trials at Leh. The same modifications will be done by GE now for LCA as well, just like these modification will be available for the GE 414 engine that we will licence produce.

What the hell, another thread for same issue..

'LCA Tejas likely to be ready for operational service by 2015' | Business Standard


The much-delayed indigenous Light Combat Aircraft (LCA) Tejas aircraft is expected to be ready for induction into operational service by 2015, IAF chief Air Chief Marshal N A K Browne said today.

Talking to reporters, the IAF chief said the indigenous aircraft will have to be modified further for operating in high-altitude areas as recently during trials in Leh, its engine "did not work".

"By my estimate it (the Initial Operational Clearance II) should be by the end of this year and the Final Operational Clearance (FOC) should take another year-and-half more," he said on the sidelines of a seminar.
The FOC is the final nod required before an aircraft is considered to be ready for operational deployment in an air force. While the IOC I of the LCA Tejas was completed two years ago, but the FOC date has been postponed due to certain issues.
Browne said delays do take place in a development project such as the LCA. "Recently we went for high-altitude trials. The engine (of LCA) did not work at that altitude because it is a different cup of tea. Even the Su-30, when it was taken to Leh, it had to be modified. So, the LCA will have to be modified. It has to do the retrials," he said.

The IAF chief said the aircraft will take part in the exercise 'Ironfist', which will be held at Pokharan in Rajasthan on February 22.

"There it will be firing the R-73 missile along with laser guided bombs etc. But a lot more work is still required," he said.

Earlier at an international seminar here, DRDO chief V K Saraswat said the LCA had completed 2,000 test flights.

At the same seminar, Browne said the IAF is planning to induct around 350-400 aircraft in the 12th Defence Plan period.

The air force is planning to procure more than 200 fighter aircraft including the 126 Rafale medium-multirole combat aircraft, over 40 Su-30MKIs, several types of transport aircraft and various choppers, he said.

Listing the major modernisation milestones achieved by the air force, he said the IAF signed 325 contract worth Rs 1.52 lakh crore for modernising the force.

"Of these, 217 contracts worth around Rs 84,000 crore have been signed with Indian companies," the IAF chief said.

In 2013-14, the IAF is planning to sign several deals including one for 126 Rafale aircraft, additional six C-130J Super Hercules and several chopper contracts for attack and heavy-lift category, he said.

On the future requirements of the force, he said advanced active electronically scanned array (AESA) radars, electronic warfare suites and unmanned combat aerial vehicles were the need of the force in the future.

The IAF chief said testing facilities of DRDO and defence PSUs should be opened up for private sector as they are national assets.

To remind people that Leh is one of the most gruesom test of a flying machines capabilities...here is a blast from the past. http://www.defence.pk/forums/indian-defence/52067-four-mmrca-contenders-fail-leh-trials.html

i read that rafale too failed there but still IAF selected it.

what about MKI performance there?
