Naval variant of LCA Tejas to undergo tests in Goa soon!

[Sam Manekshaw]

Naval Prototypes (NP)

• NP-1 – Two-seat Naval variant for carrier operations. Rolled out in July 2010.[111] NP-1 made its first flight on 27 April 2012.[61]
• NP-2 – Single-seat LCA MK 1 Naval variant for carrier operations. Both NP-1 & NP-2 are powered by GE-404 engine.[61]
• NP-3 & NP-4 – Single-seat LCA MK 2 Naval variant for carrier operations to be powered by the GE-414 engines. The design work on the two aircraft is nearly complete.[61]
• NP-5 – Another Single-seat LCA MK 1 Naval variant is planned so as to enhance the pace of certification process for Naval LCA.[61]

Don't bother until you see it flying in Naval colours.

Come on bhai, you know how these HAL types talk; always 'soon', 'may', 'might', 'looking to'.

But when asked where or when, then there is no news or answer.

1st they should hand over the two LCAs they promised to give by March end to IAF. Only 2 days left for March to end!! Then they should talk about NLCA!!

Let me ENLIGHTEN YOU.

LCA when was designed it was pure AF Version.

In 2001 It was decided to have a NAVAL VERSION.

To Design Landing Gear is such a Task that Honeywell Took 7-8 Years when A-8 Crossaires were modified for CV Version.

Mikoyan Design Bureau took 6 YEARS after MIG 29A/B was Developed to complete MIG 29K VERSION in 1994.

LEVCON Design is like changing Aerofile of A/C, Vortex Controller makes changes in Landing SPEED. It also gives added lift when set at 42.5 Degrees.

Fuselage when pitched down, changes COG and makes a/c unstable, Quadraplex signals sent to control surface actuator for x/y axis need realignment. This appears to be easy said then Tuned!!

Landing Gear needs to be accessed will it absorb "g" at Landing at full load/ 75% TOW, Stress on mainframe due to controlled crashing. Can Landing Gear withstand min 400 Landings on CV..

Also remember MAWS for Naval a/c is Total redesign when compared to AF version. Surface ships with AAW capability and "AEW" in Naval Warfare is a step ahead than land based.

Integration AShm to a/c yet again is a Challenge, Kh35. NLCA needs Radar guidance activation, radar needs to be mated with Programming core of KH 35 with FCS of NLCA.

LCA Naval Version is a Totally new a/c and progress is Satisfactory.

Yeah i got it but where is he trying to justify anything or hide any failures ?

Do you understand the difficulties in converting a airforce version aircraft into naval version?? Its not at all easy Many things like arrester,landing gear e.tc. have to be added which makes the aircraft heavy which in turn compromises the perfomance of aircraft.To solve this problem either integrate a whole new engine delievering higher thrust or reduce the weight of aircraft.
Now if you integrate a new engine then you have to completely redesign the aircraft.

Has Pakistan made an aircraft design on it's own? JF 17 is like SU 30 MKI, a joint venture. If not scram!

Luckily plane is ready. Even then after delay it has more advanced features than JF 17 BLK II like composite airframe that reduces weight and makes plane stealth ( RCS is 1/3 of Mirage 2000H (1 MS)), full digital quadruplex FCS, HMDS,FLIR, Internally embedded EW,E/O systems, TWR 1.07, wing loading 50lbs/sqft,8 hardpoints (JF 17 has 7),
150km airsearch capable radar Elta 2032 Hybrid, etc.

JF 17 does'nt even have 30% of above stuff.

Pakistanis must remember their aukad before making such statements.

Well, i think the Indian Navy has a requirment of about 50 aircraft.

The article says:

"The IAF has placed an initial order of 40 LCAs which are to be delivered over the next four to five years. We have their (IAF's) commitment for another 80 to 90 LCAs in future. The Air Force and Navy collectively require 200 LCAs."

That would make INs share as big as 70 to 80 fighters, but I guess prototypes are included in these figures.

No they will use the same engine as used in airfoce version,Highet thrust engine will be used in NLCAmk2(if they are planning to build one).

N-LCA is aimed only on the MK2 version, which is why most of the MK2 changes are aimed on INs requirements (more thrust, navalised engine, additional fuel)! The current versions are only tech demonstrators based on the MK1, they are not even fully navalised and lack the hook to land on a carrier and most likely also the airframe strenghtenings. They mainly are meant to develop and flight test the new gears, the LEVCONs and design changes compared to the air force version. The real carrier version will only be build after the airforce version of the MK2 is developed.

You can compare it with the Gripen development too:

Gripen NG (N-LCA MK1) - Tech demonstrator to develop and test design or technical changes
Gripen E (N-LCA MK2) - Fully developed version, for serial production and according the operational requirements

LCA Naval Version is a Totally new a/c and progress is Satisfactory.

Questionable, we know that EADS / Airbus assisted in the navalising process because we couldn't do it alone. ADA officials already admitted that it was far more complicated then they expected it (proves that they overestimated their capabilities) and so far we only have a tech demo version, not a fully developed carrier version. So the development time will be far longer, which would be justifiable if the end result would be a useful carrier fighter, but that however is more than doubtful. We are wasting time, money and more importantly delaying the LCA as a whole, only to claim we have developed an indigenous carrier fighter. So pride matters more than operational use and the success of the overall project.

, The real carrier version will only be build after the airforce version of the MK2 is developed.

INCORRECT Son

Questionable,

INCORRECT . Naval FLAG Staff are prepared for 3 more years for NLCA as IAC will need a/c Sqn by 2017.

Both a/c are under parallel dev.

INAS300/303 has deputed officers for NLCA

NLCA Dev is being supervised Flag Officer Naval Aviation (FONA) & ASTE Facilities were borrowed from IAF in BLR.

You mean to say that NLCA mk1 will be used as carrier based fighter and not just as a trainer or technology demonstrator??

There is No official world that 6 a/c will be TDs.
Max 2-3 could be TDs remaining will be used for Training

2 Trainers cannt be wasted as TDs
3-4 will be used for Flight formation till improved NLCA is demonstrated.
Flight formation is imperative as Senior Pilots Master Greens need to be trained.

Yeah but no mater much they improve it how will they overcome less thrust to weight ratio problem?? Why will Navy accept underpowered NLCA mk1??
