Hindustan Aeronautics Limited (HAL) has successfully conducted extreme cold weather trials on Light Combat Aircraft (LCA) Tejas in Leh.

“The aircraft made three consecutive starts using the indigenous gas turbine starter at -15°C with 85 per cent charged battery a few days ago. Prior to the start, the aircraft was cold soaked for 18 to 20 hours (even 42 hours on one occasion) outside the hangar in Leh and no heating source was used for starting,” said HAL chairman T Suvarna Raju.

According to a release issued by HAL, a team of 15 engineers and technicians from HAL worked to solve the peculiar requirement faced in starting a gas turbine engine in the rarefied and cold atmospheres found at Leh. The gas turbine starter unit of HAL, used to start the engine for the LCA, has been designed, developed and manufactured by its Aero Engine Research and Design Centre (AERDC).

The rig trials with a modified starting schedule were conducted at Leh (3260 m altitude) in July and August last year. During that period, HAL had demonstrated the capability of its starter at a high altitude of 5.6 km, the release said.

HAL had recently handed over the first series production aircraft to the IAF

guys...do we have any official pic of LCA MK2 design?

guys...do we have any official pic of LCA MK2 design?

I think ADA and DRDO are still designing it so no official pic

Would had been better to post the pics here, instead of 2 different N-LCA threads don't you think.

LCA –Tejas Passes Cold-Weather Test at Leh

Bengaluru, February 2, 2015:

HAL has made successful extreme cold weather trials in Jan 2015 on LCA- Tejas at Leh. “The aircraft made three consecutive starts using indigenous gas turbine starter at -15 °C with 85% charged battery a few days ago. Prior to the start, the aircraft was cold soaked for 18-20 hours (even 42 hours on one occasion) outside the hangar in Leh and no heating source was used for starting”, says Mr. T. Suvarna Raju, Chairman, HAL.

This success is a feather in the cap of HAL. A team of more than 15 engineers and technicians from HAL worked to solve the peculiar requirement faced in starting a Gas Turbine Engine in the rarefied and cold atmospheres found at Leh.

The gas turbine starter unit of HAL used to start the engine for LCA has been designed, developed and manufactured by its Aero Engine Research and Design Centre (AERDC). The first success was the rig trials with a modified starting schedule conducted at Leh (3260 m altitude) in July and August 2014. During this period HAL also successfully demonstrated the start capability of its starter even at a high altitude of 5.6 km.

HAL received external support from Aeronautical Development Agency (ADA), CEMILAC, DGAQA, IAF-PMT, NFTC and others for this mission.

The increased pace is now becoming obvious.
From the major remaining work
1 IFR probe integration HAL has experience with the Jaguar upgrade. Might not be same thing but it helps.
2 Integration of BVR missile. Experience with the LUSH sea harrier upgrade would be extremely useful. Because the missiles are same and so is the backend radar data processing part of elta2032.

Gun firing would be the biggest challenge.

NP1 and NP2 head to head

The increased pace is now becoming obvious.

Where do you see that?

LCA MK1 SP1 planned for March 2014 => came at the end of September
LCA MK1 SP2 planned for 2014 => not available till now
LCA MK1 FOC planned for December 2014 => now planned for the end of 2015
N-LCA TD2 planned for November 2014 => came in Febuary 2015

@sancho not pace of production, pace of testing.

In the pic you posted, the landing gear of NP2 seems slightly different. Also change in the rwr, newer version of tarang installed?

Earlier they used to miss deadlines by half a decade, now its only an year or so

I like the NP2's looks..But dont know why many of the posters in BRF hate it.
