Thank you IR for this wonderful bit of news!Indranil wrote:On Mk1, I came to know of something yesterday which made my lungi flutter quite a lot. I wanted to share it with you, but I was told to hold back a little longer till the TPs can explore that part a bit more. Will let you know as soon as I know. Will make all of you very happy. And then IDRW can go write an exclusive about it .
The ferry range of Mk1 without refueling was over 2000 kms with three tanks. With two tanks, they used to fly nonstop from Bangalore to Jodhpur with 500 kgs of fuel left in the tank. I will leave it to you to imagine the range when it is refueled.
FOC is very close now. They are going for the last set of flight test for validating the latest CLAW, avionics and weapon profile. They can finish this in about a month and feel comfortable of clearing the tests. Of no NEW demands come, FOC seems likely by year-end or therabouts.
SP-11 is getting close to get to the air SP-12 and 13 in equipping phase. They should be able to deliver Sp-16 by March of next year.

Am I seeing things or is that the Cobham Quartz radome
The Tejas solo display benefited from a lot of the early morning haze burning off, but still far from ideal. Here's SP-9 cranking it into the sky to commence the demo.

This is where MoD can step in to incubate the supplier base. The modernisation of MDL, GRSE and CSL for Type 17, Type 15A & Project 71 was paid for by MoD and not IN or IAF. IAF budgets are more focussed on operationally required acquisition and not industry incubation.Indranil wrote:3. But there is a HUGE learning curve for these newcomers. They are jumping from being Tier III suppliers to being Tier I suppliers. However, they are capable of overcoming this initial hurdle given the capital. This jacks up the per aircraft cost of the LCAs to be built. This is one of the primary reasons why LCAs are costing this much and the jump from Mk1-IOC2 (manufactured inside HAL) to Mk1-FOC to Mk1A. We are paying for this industry to come up. I know that brickbats will always use this to dish LCA in the future. LCA is not a plane for India. It is an entire industry hiding behind just one fighter. But who cares. It takes effort to know the truth. It is much easier to be an ignorant tight-ass and say that an LCA cost as much as a screwdrivered Su-30 (yes, I don't buy HAL's claim that they have the knowhow to build Su-30 from scratch).
The Tejas suppliers are all based around the Bangalore Hosur region that MoD is trying to develop as an aerospace hub. In addition Tamil Nadu is Nirmala Sitharaman's constituency. She can definitely make a difference here by making a one time investment with a caveat that suppliers amortize the GoI investment during the production run keeping component costs low.
Re: Tejas Mk.1 & Mk.1A News & Discussions: 09 February 2018
And GOI can help not just with money, but with technology and know-how and with free path through bureaucratic hurdles too. All the engineering tools and know-how that ADA/DRDO/ISRO have should be made available freely to the suppliers to lower entry barriers and overcome some of the uncertainty. The aim of these orgs should be to incubate tier-1 suppliers who can take up ownership of design of modules they manufacture, rather than just a bunch of Make-to-Print suppliers.tsarkar wrote: This is where MoD can step in to incubate the supplier base.
The second most important thing to do is giving them written assurances for minimum sustained business for initial decade or so at least.
There are many companies in India with proud and nationalistic men and women willing to work for the Nation and are passionate about their work. unless GOI taps this pool and nurtures them, it will take hell lot longer for them to form a proper MIC.
Things have improved a lot in last few years and attempts are being made in the right direction but we need to scale up the efforts. Intermittent half hearted attempts are not gonna speed up things as hoped.
Re: Tejas Mk.1 & Mk.1A News & Discussions: 09 February 2018
I had seen this some time back. Now found a sharable image. They did simulations for buddy IFR from Su-30MKI. I had wished they should check out this option and then I saw image of this simulation somewhere. Almost like my wish was granted.

GoI should incubate private enterprise through DRDO. The funding of DRDO of 2 billion annual is peanuts for what is required for build a true MIC.
GoI should increase DRDO budget. DRDO recognise upcoming enterprise by partnering with them on projects. If they are good, then DRDO should be allowed to guarantee orders for them. PSB can then provide them very low interest loans. GoI doesn't even need to fund them, they can provide low interest loans and guranteed orders.
DRDO should have stronger reporting lines to services. This way SME reporting to DRDO, DRDO projects reporting to Services, all working towards Program goals.
Examples already exists. DRDO provided 10 crore aid to a US returned researcher to work on GaN in IISc. And it worked out pretty well.
This should be enlarged.

5 x 450 kg bombs + 2 x 105 kg R-73E + 208 kg Litening + 2 x 582 kg fuel in 725 litres EFT works out to 3832 kg. Adding weight of pylon adaptors and the weight of empty EFT gives a very respectable 4000 kg payload in that configuration!JayS wrote:

However there has to be proactive involvement from services.
I feel that right from NDA youngsters have to be taught about product dev life cycle etc so they understand the challenges in designing and build.
Also perhaps strategic implications of weapons procurement etc.
Would the GOI have said no if the IA said we will work with ARDE and OFB on two small arms designs and bring it to the level reqd.
ARDE - MCIWS
OFB - 7.62 Insas
Then GOI facilitates on prod side by pvt sector involvement.

Those are 800 ltr DFTs. This configuration was already flight tested this summer. Can’t remember if it was Jodhpur or Jaisalmer. Another similar config was a 725 ltr tank instead of the bomb on the centerline.tsarkar wrote:5 x 450 kg bombs + 2 x 105 kg R-73E + 208 kg Litening + 2 x 582 kg fuel in 725 litres EFT works out to 3832 kg.

So it can carry a good payload.
Which brings me to a question around CAS.
How wolud the IAF employ the LCA in that role?
Standoff or low and fast.
Has the sq been training for that?

For MK1A, will there be a dedicated hardpoint for the EW pod? Currently the Tejas has 8 hardpoints. & for weapons and drop tanks and 1 dedicated point for the Litening pod. For the EW pod being developed, will the MK1A get an additional dedicated hardpoint, or will the EW pod use one of the existing points?
If a dedicated point will be added, then it will require some amount of flight testing to qualify.

JEC Asia-2018 Innovation Award Under Aerospace-Structure Category For the work: "Innovative Skin-Ribs Cocured Engine Bay Door"
Few excerpts from the news
PDF link: https://www.nal.res.in/medias/content_i ... d-2018.pdf
Few excerpts from the news
- -> primary requirement was to design a lightweight structure with a continuous service temperature of 180⁰C. This requirement precludes the usage of carbon-epoxy composites, as their service temperature is limited to 120-130⁰C. This requirement was met by employing BMI (Bismaleimide) composites whose service temperature is about 200⁰C.
-> development of cocured/integrated structure using carbon-BMI material has not been reported in open literature so far
-> qualified engine bay doors are assembled on LCA-Tejas aircraft and flight trials are in progress. 250 hours of flights have been completed without any issue and the engine bay door is set to enter series production soon.
-> Key Benefits = 28% weight reduction over carbon-epoxy door; Reduced manufacturing & assembly time; Maintenance-free structure (need for insulation to manage temperature is eliminated)

Re: Tejas Mk.1 & Mk.1A News & Discussions: 09 February 2018
If there is a 28% reduction in weight over carbon - epoxy, they should start using BMI for other parts as well.
28% is huge. And it has better thermal capability.

No. Tejas will take care of the roles of mig-27 and Jaguar. The IAF chief said that it is envisioned to take on the roles of MiG-29 and Mirage-2000 as well.ks_sachin wrote:Ok. But do we need a mud mover in light of payload?Indranil wrote:I don’t think we should discuss tactics in public.
The EW pod will be carried on a dual rack on the OB station. It will require flight testing. But risk is very low and confidence is high.mody wrote:For MK1A, will there be a dedicated hardpoint for the EW pod?

I understand Litening pod is required for Air to Ground missions only.

Re: Tejas Mk.1 & Mk.1A News & Discussions: 09 February 2018
The IAF pioneered the use of Litening as an IRST in Su-30MKI and Tejas due to its far superior quality optics compared to Russian ones. So Litening is used in A2A modes as well.ashishvikas wrote:I understand Litening pod is required for Air to Ground missions only.

The Mirage 2000 did that in 1999 at Kargil and Jaguar do do regularly, so yes, that capability well exists.Trikaal wrote:At present is buddy targeting possible?

After an F-16 was hit by a Stinger fired by TTP, the Pakistanis use F-16 for long distance destination using Lockheed Sniper pods outside Stinger range and JF-17 as bomb mules to drop the actual bomb. The JF-17 has no guidance capability and is dependent on the F-16 for designation.

^^buddy targeting is no use w/ stealth (ie JF-17 can't designate, it is lame duck!). /JMT
A combination of stealth airframe, plus buddy targeting and effective cloaking (a good long-ranged AESA with LPI+switch off/passive) with decoys would work.

BTW, at the moment the acquisition plan for Tejas is as follows: 40 MK-1 (ordered) + 83 Mk-1A (RFP stage) + 108 MK-2 (prospective) = 231 LCAs.
