First Article will always have teething problems. Thats why it doesn't make sense to constantly keep changing specs with small orders.

HAL finalises plan to produce military helicopter on par with Boeing's Apache Guardian. In an ambitious project with strategic significance, aerospace major Hindustan Aeronautics Ltd (HAL) has started ground work to produce a 10 to 12 tonne attack helicopter by 2027 which will be comparable with so...

No that easy. Someone in the know can clarify but I believe every foc point(already proven in flight testing) will have to be demonstrated before delivery.

Nope, only basic OEM level taxi runs and flights followed by User Acceptance flights. 6-8 flights in all give or take some.

The canard position of the Rafale coming it to land is exactly what ADA is going after. You were right.

I can't quite remember the reference now.

Good article providing detailed make-up of the DMA and a further explanation (and expansion?) of DMA responsibilities and powers. Bipin Rawat headed-DMA will give preference to domain experts like DRDO and ISRO The present structure of the DMA has the secretary at the helm. Under him, there is a se...

JayS, I meant Detailed Design Phase of Mk.2 has been sanctioned. I believe the initial amount seeded back in 2009 would be for platform (configuration) & capability studies. If DRDO had requested funds in 2018, then it would have been "approved" recently onlee and this aligns with rec...

the funding issue is not funding for constructing the AC itself, but all that accompanies the fleet - the destroyers, frigates, submarines, etc, their armaments, and the personnel and their pensions. I have seen this arguement before... But this doesn't sound right... Navy's requirement of 3 carrie...

MPATGM itself is made similar to ATAGS with significant involvement of VEM. Very unlikely that there is another NAG based mPATGM program by DRDO. I thinknchances for other ATGMs than DRDOs MPATGM are pretty slim. Anyway BDL and VEM will be manufacturing it. Amogh3 and AsiBel and any other such offer...

Fanne sahab, no need to hyperventilate. If you put half the efforts you put in writing these long posts, in tracking tenders or asking question to HVT on teeter, you would know better and have more peace of mind. Mk1A has a overhauled DFCC with elements from MWF bring it to at par with MWF, done mos...

As I was saying to raman saar elsewhere, I was disappointed at only 2 JS in DMA. I was expecting much larger number, given how much is being said to be moved in the DMA. I think the only way is for Modi-RS duo to lean heavily on the Bureaucracy using their political weight to make them fall in line....

by the look of it, the pylon has some kind of EW payload in it.

I remember to have read that with hyper-spectral camera, its possible to positive id things like Aircraft using the multi-spectral data from a single pixel and previously known signature from the database. I was thinking the same would be applicable for GISAT while detecting Naval ships. Not sure if...

I frankly do not understand why HAL would need so much time for MK1A first flight. It should have been in 2021 latest, not 2023. The plan is in place since 2016. HAL seems to be working full throttle on it. Then why 7yrs for a relatively small change in MK1..?? ADA will go from MK1 to MWF in roughly...

JayS

With ramped up production, we can do the 83 Tejas Mark 1A jets within four years. HAL should not make such statement. Any production run needs ramp up and ramp down. The arithmetic is not 1st standard level in case of production. From current situation, Min 6-7yrs production run with 20/yr and min ...

Not dry but wet, in this context ie the intended Mil application. But in other context, as a high BPR civil jet engine for Business jet class like the Falcon series, it could.I think. I am not so sure that he was speaking of wet thrust. I think we was speaking of materials. With a higher TET. See t...

I also think its one of many study configs, we should take it with pinch of salt.

It has been sanctioned in 2009 itself. DRDO asked for 800Cr additional fund for FSED-3 in 2018. We don't know what happened to it.

Interesting tidbit. Sorry, cant copy tweet text on my cellphone for some reason. https://twitter.com/hvtiaf/status/1225461995849187328?s=19 ---> There was a study done for Mark-1P (Mk-1 with 1 meter long Plug - same as original Mk-2 airframe) as a successor for Mk-1. It was shelved due to increase i...

Excellent cockpit..given how good the MMI is supposedly on the Tejas, MWF will be a leap forward. Should be almost similar with the TEDBF/ORCA and help with the AMCA cockpit development as well. It is very impressive for sure ! I dont understand this space well - but to me incorporating a single LA...

You are very close with those first order calculations. At AI'19, the gent presenting HTFE said that the engine can easily go up to 35 kN of thrust. I am assuming he meant dry thrust. Above post belongs to gyan-only I made for you. Let me know if you are having a problem posting there. Not dry but ...

Unless m forgeting something, this is the first remder we are seeing of AMCA with DSI. With it comes the swept forward intake to put the lip near the shock produced bubthe DSI bump to capture air in optimal fashion. Exactly like how F35 has it. Looks like one of the study model. May not be the final...

JayS

Why? Why this lack of leadership/responsibility? Dont think you have looked around for what is happening on MK1A in HAL. As such, Its impractical to expect HAL to make flying prototypes yrs ahead of production, especially when there is no Dev funding that they are getting separately and their own f...

There was a Tech Focus issue last year on Composites. IN that there was a section on this composite hull, that picture it from that issue. DRDO claims 40% weight reduction, which is massive. This ICV which is about to be integrated to make the prototypes for testing is 12T class (is this Abhay Mk2....

HAL is asking for an entire aircraft program based on some rather crudely made 3D models. LOL. What I suspected earlier, that HAL is perhaps trying to usurp MWF design from ADA seems to be correct. I like the hunger in HAL. They do in fact desing most of the aero-structure of LCA and a significant a...

JayS

Jay, The outer lip of a DSI intake doesn't move inward commensurate to the width of the spill duct. You see the DSI also spills the boundary layer. Therefore, to get the same amount of clean air as a non diverted intake, a DSI intake's outer lip is roughly the same distance away from the fuselage. ...

Traditional fabricated-aluminum bulkheads, frames and racks have been eliminated and replaced by single-piece machined components. Five-axis machining of bulkheads results in major weight savings in the mid- and forward fuselage, while holding tolerances three times tighter than those achieved in t...

Meteor was never going to go on LCA. There were just a bunch of lifafa articles promoting it. Lokos like they now realised the futility in dishing out payments to journos on this matter.

As per my understanding, the production goes as follows: 1. The front, mid and rear jigs are used to create the three major subassemblies. There are six sets of such jigs. 2. They are joined together with the wings and landing gear on the designated bay on the hangar floor. There is no jig for that...

JayS

I might as well try for RS entry then.

Well, there is no big business secret about it. In fact, HAL needs to publically state such strategies that they might have.

JayS

I will have one more opportunity to talk to the guys soon enough. I will try to pry out answers. Add one more question - Once the suppliers are reached to 8/yr rate which was planned AFAIK, Is HAL planning to off load more sub-assy work that they themselves are doing currently, eventually reaching ...

Below video makes it crystal clear. Thought i should post this video after reading recent idrw article on this. 1. Those 4 prototypes are of production stds and no TDs. 2. First flight is by 2021 end or 22 beginning. Crystal clear since AI-2019 that production standard MWF prototypes will be built ...

8 micron would have been phenomenal, is 80 good? I googled up, it looks like the neighborhood guys in Massa makes 80 micron precision stuff. Is that much precision/margin good enough in aerodynamics? I guess end goal is full interchangeability, and if that goal is reached who cares if it is 80 or 8...

If not, I would not hang my hat on the 65kN == full fuel; IMO, unlikely that the first sorties would happen on full internal (vs. sufficient fuel for the test plan) We have no idea that full fuel load took off with 65kN....No way to surmise that. Well there's a way. Nice that we have HUD video. I d...

I don't know about that unless you got that from an ADA source... Cmd Mao had mentioned it in his AeroIndia Seminar a long time back.
