Hmm, I am actually far more eager to see the LSP 7, the Navy variant can come later. Ideally, in a dreamworld, I'd like to see:

Snecma-Kaveri powered Tejas (<6500kg empty; 90kN thrust) start FSP around 2016-17. In the meanwhile get 2 sqds of Tejas mk1 running on GE-F404IN20. At least 200 units.

Use the 100 GE-F414s to get the Naval version going - (7000kg empty, 100kN thrust), 100 units.

can anyone confirm if the French CVF carrier will power the cats using EMALS system or steam? how will the conventional powerplant generate the steam needed?

to answer my own question, seems the french PA2 carrier was designed for 73,000t but dropped back to 60,000t for cost reasons. and it will use the american steam catapults and additional boilers for that. power plant will all electric driven by RR gas turbines and a diesel engine.

http://www.defenseindustrydaily.com/fra ... ect-01621/

its time to bite the bullet and open talks for the catapult system. must be designed into ADS2 from day1 to permit either F-18I or Rafale-M ops and E2-DI. it will also mandate a size of around 65,000t and 300+m..... should put in 4 cats to maintain sortie rates

i am little confused here , weren't Tejas SP-1 and 2 , were supposed to fly by this year ?

If I remember correctly, there are only two countries in the world that know how to build steam catapult or EMALS catapult systems, the UK (who invented the steam catapult) and the US. And I'm not sure if the UK remembers how to build steam catapults any more. Everyone simply imports them from the US and I don't think the design know-how is for sale.

Yes, Only the uncle can provide us with such technology.

And again Uncle may insist the F-35 + E2D buy in return for selling the catapult tech for ADS2.

The Defence Acquisition Council (DAC) has approved the production of nine units for the navy, roughly half a squadron, that will ostensibly operate off India's first indigenous aircraft carrier currently under construction at Kochi.

Perhaps you can help these guys. After-all aircraft building is such an easy job and those worthless guys at ADA/HAL are getting their salaries just for their attendance. Go ahead and suggest how to get the LSP-7 and NP-1 in the air and also suggest how to convince moulankar sir etc to fly them. Thanks in advance
Cheers!

Edited to remove what may have felt like a direct attack on raghuk. That was not my intention. Just to be clear and put it on record my intention definitely was a criticism of HAL/ADA. There are way too many deadlines given and dates missed.

What gets my goat however is that while the services are free to be attacked, DRDO is treated as a holy cow never to be criticised. Any criticism is taken as a direct attack and there is a fear that people will take affront and disappear :eek:

Come on guys

You want participation from people involved and then you treat them like this - they will be driven off

no matter how frustrated - you have to tone done.

You cannot take it on raghuk - I am sure the management of where you work makes a lot of statements too

you wouldn't like it when people take it on you???


You can use that with fellow armchair jingoes though :)

It is easy for people to lose faith in the Tejas program and all the negativity surrounding it doesn't help the cause at all. How all the news items regarding the Tejas would carry one para at least, about how it has got delayed, is in making for 30 years, and how the services are unhappy. So the agencies would give estimated time. Also, would it help if there was no news at all? I am sure people here would get more frustrated with it and cry foul!

This approach of continuously bashing HAL and if that is not possible, its employees, is juvenile. At the very least, we must avoid these personal attacks.

raghu, please learn to ignore posts that do not add anything. your efforts are better used doing real stuff. when you have the time we will be happy if you update us on a thing or two.

if posts get too much to bear, do NOT engage, simply report the offending post(s) to the mods by pressing the red ! button.

Anyone who reads/watches programs about flight incidents/accidents will have seen at least one episode that features an incident in an aircraft in which the following problem was discovered AFTER the aircraft went into service.

Quote:
Express had reported earlier about a fuel leak on LSP-7, which forced the Aeronautical Development Agency(ADA)-HAL combo to ground the entire fleet. This had pushed the programme further behind the schedule by four-five months -- the time taken by designers and engineers in re-arranging the butting of fuel and hydraulic pipes to prevent them coming in contact.

The Kiran which when it turned up lead to the fuel bottoming out to the other side knocking out the engine cold. Goes to show the complexity involved even in designing the interiors of the fuel tank of an aircraft.

Nice..notice the change at the base of the vertical fin? The intake design has been changed and smoothened out..drag reduction measure perhaps? Saw it on the Tejas Mk1 and 2 models at AI-11, but they've introduced it for Tejas Mk1 itself.

Someone in ADA obviously took that "kabaadi waala" comment by a certain Prof seriously..

Funny thing is HAL/DRDO/MOD/GOI keeps complaining that there are no tier-I, tier-II companies. L&T, Sundaram Fasteners, Bharat Forge, Pipavav (what is the meaning of this name anyways...having a hard time remembering how to spell it), M&M, AL, etc etc.. complain that HAL/DRDO/MOD/GOI are not giving private companies opportunity to play a role. :roll: :roll:

So, who is providing the components today for Tejas? Why can't they show a nice contract and rope in private companies?

Too many chicken-egg scenarios

Yes. But in fact this business of inviting private participation has been on only for a decade or so now with increasing private involvement in stalls in Aero India. In fact last year, on this thread we discussed a news item where some HAL bigwig admitted that the biggest problem was going to be mass production of small (and larger) parts for the LCA production line rather than the one-off items that was being done for the prototypes. Obviously, if they get suppliers to do that and keep quality high and costs low then the problem is solved.

I think the use of the word "pin" is significant as is the mention of cost. High quality pins/small parts may cost a bomb if an investment in machinery has to be put in up front by any private company. HAL can't help here but GoI can help by giving soft loans and tax breaks to companies that are willing to invest in the machinery/floor space to make small parts. The investment will really pay off in MCA or FGFA, because the same factory can then continue to produce pins/rings for the next A/C.

The other unrelated issue is "transfer of technology". When we buy a Jag or a rafale, it was basically unprofitable to set up factories for every pin/ring. Either HAL had to set up a unit for that or it was imported wholesale. If the company in UK/France shut down or if sanctions were applied that small pin - the proverbial nail in the horse's shoe could ground a plane. So we need massive, ma-assive private involvement of small players to make thousands of little parts.

Looks like a cover to me. I went to the Bengaluru place where they are making an armed forces memorial park and took photos of the resident MiG 23 there. Parrots were nesting in the gun port and the intakes.

At the risk of being laughed at, could the hump be a satellite data-link now? I think the seams join too neatly for something removable, like a cover as Shiv ji suggests.

do you mean a cover that would be taken off when its about to fly? I don't think so. If they needed to cover the intake, it would only require a cap, not what appears to be a smoothened fairing.

IMO, the change that Sid pointed out is likely due to area ruling concerns. And the smoothening of the intake could have been done as a result of drag concerns
