What happened to the canard of the Naval LCA? The one shown looks standard same as IAF LCA? BTW, LCA with 3 models IS India's "JSF". A V/STOL version can be developed later. They should put 100 cellphones on it and it becomes an F-35.

The article from Mao ji gives me Goosebumps!

How about an annual $ 5000.00 or thereabouts BRF prize for outstanding contribution to Indian Defense Indigenization.

Articles don’t come better than this, it outlines enormity of the task these patriots have undertaken and proved why these indigenous efforts are irreplaceable.

https://twitter.com/ReviewVayu/status/1 ... 86050?s=20 ----> Shortly, will send 8 tweets on the Naval LCA and an in-depth article of what it took for the landings. It's a fascinating read. All enthusiasts MUST read it before commenting. Will tag Commodore Jaideep Maolankar (MAO), Group Director FTO & Chief Test Pilot here. Our cover story.

https://twitter.com/ReviewVayu/status/1 ... 73600?s=20 ---> 3/8: Probably the most important lesson learnt during this test phase was that a conservative design does not necessarily generate addit safety. In the case of the nose oleo, the design case was for a virtually impossible 3 point landing at 1400 fpm.
https://twitter.com/ReviewVayu/status/1 ... 73600?s=20 ---> 4/8: Preparations by the crew have been achieved by a combination of two factors: deep immersion into the aircraft’s design processes and infusion of knowledge from the ‘best in the business’ at the Carrier Suitability Division of the US Navy.

Very rarely do wallpaper sized images come. This is one of those times. If you are an aviation buff or just love desi maal, you need to save these images for your personal collection.
Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
Beautiful shot. Really shows off the best looking variants of the LCA..and clearly illustrates how much better the Navy's color scheme looks as compared to the IAF's dated color scheme.Rakesh wrote:https://twitter.com/ReviewVayu/status/1 ... 36960?s=20 ----> 5/8: As would be expected, there is a lot of justifiable pride associated with these achievements, most of which are uniquely ‘Indian’ and will naturally far outlive employment of the current test aircraft.

Superb pic! can see so many details of the LCA Navy cockpit in this pic. See the Hook Off and Down switch and the Fuel Dump switches. Both are unique to LCA Navy. Can also see 2143 kg of internal fuel, also indicated by the green color of the wing, fuselage and aft fuselage fuel tanks on the left MFD. Can also see a 'Clean AC' button covered by a glass cover, which when pressed most likely jettisons all external stores.Rakesh wrote:https://twitter.com/ReviewVayu/status/1 ... 14144?s=20 ----> LCA-Navy's cockpit!

may be a very basic question to ask..but does it have a start button ..or does it have some key mechansim..

The spine behind the canopy looks bigger, the shoulder looks bigger. Perhaps even the wing area.
Obviously an optical illusion or I am just thinking its bigger because its a 2 seater

Couldn't help but imagine how wonderful the view would be with a bubble canopy like an F-16 or F-22 ...
I hope they are doing it for the AMCA.
Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
Also I noticed a peculiar pipe-like fitting running through the borders of the canopy with many holes in it. I have never seen anything like it on any other a/c.
Does anybody know what it is?
My guess is it's just there for added strengthening but I could be wrong. It surely isn't for air-conditioning ...

Maybe defogging? Warm air to manage fog as it is operating in rapidly changing humidity condition?NachiketM wrote:Also I noticed a peculiar pipe-like fitting running through the borders of the canopy with many holes in it. I have never seen anything like it on any other a/c.

Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
No. The cabin is pressurised and that prevents fogging up.Reddy wrote:Maybe defogging?

It's a strange contraption and none of the fighters I have seen have it.

Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
it will be for defogging/demisting,
pressurisation alone will not stop this happening when humidity changes dramatically..
it is part of the air conditioning system... scroll to page 9 of this falcon 2000 manual
http://www.smartcockpit.com/docs/DASSAU ... ection.pdf
misting may/will happen when descending from higher levels onto the surface
of the very warm Indian ocean
the aircraft on the right, as we see them, has much greater nose wheel oleo extension.
hence it is sitting higher.......
perhaps they are testing with different pressures in the oleos
same models of aircraft type will not be different in dimensions
all jet engines are started with a button or switch

Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
could it be a fire suppressant system?!
Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
No, it is the vents for the ECS systems. It keeps the canopy at the same temperature as the cockpit. IT is there even in the Tejas. It is painted black there and hence gets camouflaged into the canopy frame.
Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
Indranil,
How common is the structure of Naval LC to the Tejas?
I know the undercarriage, the front canards, and the engine.
Can it be made on the Tejas lines during gap between FOC and Mk1A at HAL?

Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
Ramana sir,
Think of LCA has 3 fuselage parts: front, middle and rear; the wing and the fin. The front fuselage section, wing and fins are identical. A lot of the LRUs are identical. So, I can't imagine why NLCAs cannot be buid from the same assembly line.

Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
this could be the best use of downtime at HAL - build NLCA - risk mitigation vis a vis Mig 29 (I believe at least in AA role, NLCA has adequate range and time on station with enough aa missile). A mixture, where NLCA provides AA coverage (and if A to S or A to G if feasible) while M29 goes out for A to S and A2G roles).
Also we advance our TEDBF with a practical NLCA, many tech can keep on maturing on NLCA. A 16/32 plane run for NLCA may not be bad. When TEDBF comes over they get handed to IAF (and if needed, some parts rebuilt - e.g. landing gear).

Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
I am just wondering what if the downtime is used to make LCA Navy trainer? As needed, it can be used as Navy trainer, air force trainer and in combat for IN and IAF. It may not excel in the last 2 roles and not perhaps required for the first but practically it can be used for any role in dire straits.fanne wrote:this could be the best use of downtime at HAL - build NLCA - risk mitigation vis a vis Mig 29 (I believe at least in AA role, NLCA has adequate range and time on station with enough aa missile).

Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
An article on how the CV is affecting the IA's ability to respond to both fronts,because of budget blues, basic small arms,ammo,etc. unavailable, will have a cascading effect and the IN,whose slice of cake has gotten even smaller will have nothing in the pocket for the NLCA. It is more likely to buy more limited numbers of 29Ks,to fill any gaps,being cheaper and a more cost-effective solution.Just a sqd. of NLCAs, will find it v.difficult to set up a future domestic logistic supply chain. What money we have ,let's for now plug the ASW helo gap.
Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
I don't want to go to NLCA production. There are no orders and IN is not keen on it. It is on TEDBF, and work is going fast on that. I can tell you a few number of internal reviews with IN has been completed. IN considering the NLCA Mk1 as LIFT. It is mighty pleased with NLCA Mk1 tests. The test results are better than anticipated, kind of anticlimactic in a way. The team demonstrated 3 hot refuels resulting in 4 traps and 3 takeoffs for 3 hours of continuous flying on a single aircraft. Nobody expected that from a prototype on its second day ever onboard ANY ship. The design team also learned a lot about what works best onboard a floating hangar and flight deck.
Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
Gupta sahab, it is easy to blame HAL and say if only it was for another company (preferably private) things would be rosier.
I guarantee you, paisa phenko tamasha dekho. Double the orders, and one more line will come up magically. On the contrary, if you don't pay the dues to a company, to the the point that it has to take loans then NO company will invest in capital intensive automatic drilling machines which are required for large scale production!
It is quite simple only, the use and abuse is bidirectional. One has to be deliberately biased to find malice on one side only.

Sirjee, how many C295Ws has Tata built based on confirmed orders? If they have not built one, then which quality of industrial management are they missing?agupta wrote:Hmm... there are incompetent Private companies too - they get run out quickly, so don't see my note as a push to hand this over to a private agency. And my grey hair have been witness to many accounts of Services playing fast-n-loose as well. That's not the issue.
My point is simply this: Taking on debt to finance operations is a VERY COMMON thing to do in big industrials. Is HAL really doing a rona-dhona about it or is this angst an internet forum construct ? If its the former, then geez - that's disappointingly far from even a best-of-India class professionally run industrial management
That's your opinion. I am not going to try to change it. But MWF, NLCA, TEDBF etc. are currently not HAL run projects.agupta wrote: I am not arguing for an extra line or production expectations. I think the current evolution of Mk1A--> MWF / NLCA TD --> TEDBF is a wise and mature thing to do. I don't believe even if HAL got more cash or orders for Mk1, its efficient enough to manage it - it WILL screw over and mess up MWF and TEDBF EIS timelines... and THAT transition for playing defense to offense with the foundation the Tejas program has given us is what I would love to see ASAP.
Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
If MoD hadn't paid dues to the tune of thousands of crores to a private company (foreign or domestic) there would be arbitration proceedings going on right now and MoD would end up paying through their (taxpayer's) noses eventually. They know that very well. So they don't default on payments to private (especially foreign) vendors. With HAL, it looks like there is a "sab kuch chalta hai" attitude since it is a government agency and is not going to sue the MoD.
And yes if they had defaulted on payments to a private vendor that vendor would not be drilling a single hole (in a manual or automated manner) to fulfill more orders.

Re: Naval Tejas Mk1: News & Discussion - 03 January 2020
1. IN doesn't have a trainer that can land on deck. NLCA Mk1 trainer will be that LIFT. ADA trying to sell that concept to IN. IN sees the merit. Short on money.agupta wrote:You've raised an interesting possibility of the NLCA --> LiFT role ! Interesting. I do recall you advocating for a clean sheet AJT/HAwk-scale LIFT design as well, right ? Are you thinking we may end up having 2 different LIFT candidates - separate one for IAF and IN ?
2. HAL has put forward LCA AF trainer -- as LIFT for IAF and other AFs. There is virtue in it. But, I don't see the differentiator from the Boeing/Saab T-7, Lockheed Martin/KAI T-50, the Yak/Hongdu L-15 and the Chengu/PAC J-17B. If I were a foreign buyer, I would go the T-7 which has ~500 orders on day 1, and is designed from the ground up as a standalone LIFT. It's maintenance is going to be the least by virtue of the design choices it has made.
3. Therefore I have khayali pulao design in my mind of next generation AJT/LIFT which is based on single-AB engine. A modern day Mig21/F-5E. It will be cheaper to acquire and maintain than all the above (except the T-7). Performance wise it will lie in between a Hawk and an LCA Mk1. It can chose a slightly more performant AJT because it is on a three airplane syllabus and the IJT is a pretty decent jet trainer.
