Great News.

Noob pooch, what are differences between NP1 & NP2?

It looks like they have taken the NP 1 and covered the back seat cockpit canopy with a black chart paper. Not good looking at all :((

^^^ This was known to all. It is similar to the Mig-29K in this respect. I can't say whether the LGs are different. But one obvious change is the louvres instead of the blow-in doors on the intake. Also there is a fairing for the gun. NP1 did not have it. The doral intake has been improved from the LSP 7 and LSP8. I like this new one better.

Recovery Parachute doors are hinged. Was it done earlier on LSPs or its a new change on NP2?

How many nations make naval air crafts? I mean from design to production, not the cut-paste variety (although they can be potent too).

OT here, but it would be very interesting to see what decisions are made WRT the AMCA. That is where the real gain should be felt - naval or not.

NP1 is tech feeder to NP2, let's not go by headings of 'NP2 overcame defects of NP1' and such and therein.

There have been several improvements (not defects).

The space for the rear seat in the trainer variant is packed with gadgetry in NP-2. Does anyone know what addition capabilities they bring? Or is it just about moving weight forward to maintain center of gravity?

http://ajaishukla.blogspot.in/2015/02/while-iaf-drags-feet-over-tejas-naval.html

Even as the Indian Air Force (IAF) wrangles over details in the manufacture and induction of its first squadron of Tejas light combat aircraft (LCA), the Indian Navy is powering ahead with its programme to develop a naval version of the Tejas.

In Hindustan Aeronautics Ltd, Bangalore (HAL) on Saturday, the Naval LCA project got a major fillip when the second prototype made its first flight.

The “navalised” Tejas will be based on two indigenous aircraft carriers. The first of these, INS Vikrant, is currently being built by Cochin Shipyard and will enter service in 2018.

The navy’s newest aircraft carrier, INS Vikramaditya (formerly the Gorshkov), fields only a complement of Russian MiG-29K fighters. However, the 40,000-tonne Vikrant and its successor, a larger (possibly 65,000-tonne) aircraft carrier that could be named INS Vishal, are likely to field the so-called Naval LCA as well as the MiG-29K.

Termed Naval Prototype-2 (NP-2) the new single-seat prototype differs significantly from its twin-seat predecessor, NP-1, which first flew in April 2012. Like all naval fighters, NP-2 has a reinforced undercarriage to absorb the impact of landing on aircraft carriers. Since the pilot must descend steeply to touch down precisely at a spot on the carrier deck where his aircraft’s tail-hook catches on a set of “arrestor wires”, this landing is often likened to a “controlled crash”.

According to the defence ministry, the new prototype corrects several deficiencies observed whilst flight-testing NP-1. The Aeronautical Development Agency (ADA), which oversees the Tejas programme, says NP-2 incorporates most avionic hardware components that the navy has demanded.

These include “plug and play” modules that will accept software modifications for aircraft carrier landing aids (like a Levcon Air Data Computer), auto-throttle, and special lights. NP-2 will also incorporate the arrestor hook, a digital data link for tactical information, and the Israeli Derby long-range air-to-air missile.


NP-2 was piloted by Captain Shivnath Dahiya, a naval test pilot with the National Flight Test Centre (NFTC). Another Tejas, piloted by Group Captain Suneet Krishna, “chased” NP-2 all through its flight, observing it externally.

Meanwhile, the Naval LCA programme is transitioning from regular runways to a so-called Shore Based Test Facility (SBTF) --- a full-sized, land-based model of an aircraft carrier deck that has been built in Goa. In December, NP-1 had taken off from the SBTF.

The next major step in the Naval LCA project will be an arrestor-wire landing, carried out at the SBTF.

TBH, personal preference and all, completely dislike how the NP1 looks. far too many curves and too short/stubby an airframe.

waiting for the longer Mk2 hopefully that extra 0.5 mtrs will make it look sleeker.

While its only a prototype, I notice it has RWR suite, as well as aerodynamic improvements like rear wing root fairing blended to wing.

The news article also mentions Derby compatibility, as well as air data computer for levcons. That's a pretty fast ramp up from first to second prototype.

Hopefully the 8 PVs will lead to a fully functional Mk2 right from the start.

I'm given to understand that two seater F-15, F-16 & F-18s have better area ruling due to the cockpit hump than single seater equivalents.

Did anyone else notice that this NP-2 seems to have the APU inlet looking like a cross between early LSPs and newer LSPs.

Early LSP (linking the URL, so as to not blow up page formatting):
http://www.bharat-rakshak.com/IAF/Galleries/Aircraft/Current/Fighters/Tejas/LSP/LSP02.jpg.html

Newer LSP:

and now look at the APU inlet on the NP-2

Any ideas what the deal is here?

armenT - possibly the raised canopy of the naval variant reduces available flow to the APU in the dorsal region at some aoa's - therefore possibly a different type of inlet had to be used?

So, the NLCA already is ready with Derby, i.e. bvr capability. should be easy enough to field this on the IAF version. what else is needed for FOC now? this was probably the only thing a bison could do better than Tejas, now that this is close to done deal, one eagerly awaits additional order ofat least two sqds for the mk1 due by 2022 when the mk2 is ready.

There is really no need for Rafales now, some more mki, perhaps a sqd worth m2k, and we should be all set.

No, it has got nothing to do with NLCA. Basically they are trying to reduce drag. With LSP7 onwards they went with the smooth hump. First they had a slit, but it was not providing enough air.
Image

So they did a quickfix scoop, which looked really dirty. Must have been really draggy as well.

Image

They have fixed the same in NP2. All LCAs henceforth will have the dorsal air intake shaped like this.

No wonder it is disliked by its intended original user. Note to DRDO/HAL/NAL - Next time make it blonde (gold canopy), flat all round (for stealth) and most important - paint it white and blue not grey, not yellow and definitely not black. :lol:

Wait for the whole plane to arrive in Tippy grey. In my view, it will be the second best looking LCA, the best being the trainer version.

Ofcourse NP2 is not the most optimized NLCA that we could have built. But it is inline with Navy's philosophy of building incrementally to save time. The best description of this was given by Capt. Mao. Basically we need 4 optimized variants. 1. LCA tejas, 2. LCA trainer, 3. LCA Navy and 4. LCA Navy trainer. To compress the timeline, they have done with about 2.5 airframes: 1. LCA Tejas, 2. LCA trainer (PV6) cum LCA Navy trainer (NP1) cum LCA Navy (NP2). This makes NP2 have too large a cockpit (this is not good for drag). Moving on to LCA Navy Mk2, this will not be the case. In the Mk2 we will 3.5 airframes, and LCA Navy mk2 and LCA Tejas Mk2 will be completely different. LCA Navy trainer and LCA Tejas trainer will have the same cockpit, but different landing gears etc.

Albeit, I will never be able to give any credit to IAF if LCA succeeds, other than providing the pilots to test fly the aircraft (in process, killing their careers in the IAF).
