I would say around 60 kN too, but with a better TWR.

Indranil

As I had said earlier, IAF demanded (and rightly so) that Tejas should now be fully serviceable at BRDs with a certain percentage of guaranteed availability. HAL was making sure that this will indeed be the case from here on. There were some small problems e.g. with the HUD installation which has be...

https://i.imgur.com/jdZXBQb.jpg ...... It appears the previous CEO was the reason for all of the delays and drama. In few months, we can expect withdrawal of fake corruption charges filed on senior people, who made possible train-18 a reality. Withdrawal of corruption charge is not enough. Those re...

It is not like DSI tech is not ready. The DSI of one aircraft doesn't work on another. To develop the DSI for Mk2, they have to do CFD, then WTT, then in flight testing, and finally quals. That's a resource allocation question. Should Mk2 be made to wait for it? When Gripen E, and Rafales can contin...

Qatar's follow-on deal for 36 more Rafale aircraft cost $1.3bn in 2018. Follow on orders are a lot cheaper. If we go the g2g way for the 6 MRTTs (after failing to buy them despite 3-4 procurement process rounds), that will good. Those were around $3bn-ish. So definitely not "cheap". Sound...

I am really looking forward to integration of SANT on Hawks. With their slower speeds and low operational cost, they can be a way better anti tank aircraft than any other fixed wing in IAF service.

Indranil

For those wondering why 36 months: What was the delivery time for first Rafale delivery? From an existing assembly line, same plane, same part manufacturers, only some "India specific changes".

Indranil

No. It is not possible to do so the way the eprocurement site works. The links are reachable only after a captcha and become stale within a few minutes.

May I also say that the Saras Mk2 is quite a looker. The proportions are just right. Saras Mk1 looked stubby to me. Currently, the plan is for production at HAL. But I hear murmurs of pushback from HAL owing to competition to its "own" Do228. If I were HAL, I would slowly wean off of the 2...

Indranil

Typically, that does not require big changes to the airframe. But it places restrictions on the envelop and a lot of time in qualifications.

Indranil

More details: Mk2 will carry much more fuel (1832 kgs from current 1568 kgs). With a much larger wing (31.2m^2 from current 25.7^2) and much higher aspect ratio of 10, its ferry range will improve significantly to 2400 kms (with 45 mins reserve). For brochure numbers: 2700 kms. It will cruise at 400...

Indranil

I am actually not sure if Mk2 will have the GTSU or an APU/ATS. Latest tenders speak of the latter. Retractable AAR seems more likely than not now.

Indranil

I will leave out culture here. What is the design by ignorance happening right now? They are reusing the ALH design to the hilt. If anything they are simplifying, e.g. the transmissions in LUH, IMRH. It is somewhat boring from that aspect if you leave aside the RUAVs. I am a bit sad that they are no...

Indranil

Be rest assured sirjee I have had the good fortune of talking to a few.

But lessons not learned? Are speaking of design or culture?

Indranil

Chetak ji, One thing that I can say for sure is that you are a valued member here. I assign weightage to your posts and that's why they matter to me. The problems with Dhruv have taken 20 years to lick. They are still licking it. But the knowhow that they have gained for designing, for building is V...

This is an offer?!!!

It's a pity to come here and find a discussion on how the Panther is a potentially good buy for India! Today?! Seriously? Imagine a news article in France: France considering to buy Dhruvs MKIII. The French will laugh at it. The reverse is not true in India. And by the way, Dhruv is WAY more technol...

ADE has put up a tender for WT model of flying wing UAV with wingspan 5.0m, length 4.0m and height 0.631m. Which one might that be..? Any bright ideas..? Ghatak..? One more tender has come out now. This time for the manufacture of the actual airframe. It is not UAVTD/Swift. It has a vertical tail. ...

Indranil

Indranil, Basically the Avros have airframe life you are saying. What new engines would you suggest? The C295/C-130 would be adequate? Reason is it could be used in Andamans Most of them have 75-80% of their 100,000 hours of life left. HAL chose PW127E (or M?) as the upgrade. They fly on the ATR72-...

Vivek, you know there is no way that the C295s can replace the 32s in hot and high performance. C295: MTOW 23,000 kgs, engine power: 2x1972 kW, wing area: 59 m^2. An32: MTOW 27,000 kgs, engine power: 2x3812 kW, wing area: 75 m^2. There is no comparison in hot and high conditions!! I was baiting som...

Indranil

C295 is not a replacement for the Avros either. The Avros hardly do anything! Their only proper use right now is in pilot training. When it is use for communications, most of the plane flies empty. The C295s will create a new niche which is currently not catered to by anybody. One could say that the...

Indranil

One of the parameters that will decide whether the C295 will also start replacing the AN32 later is going to be their hot-and-high performance. If one recalls, the AN26 was the original baseline aircraft that was modified to the AN32 to enable operating from high altitudes with high power requireme...

In the case of the Netra, they sent dummies of the same form and fit as the actual radar. The connectors were also form perfect so that internal wiring could be completed by the OEM. I suspect it will be the same here. One part of me says, just don't do anything much. Use the same AAAUs and consoles...

Indranil have a question or two please. Would it be fair to say that the iaf launcher is designed in a way that it can be decoupled from the tractor/heavy truck to remain in place for a period of time. Whereas the army one looks proper mobile and fully containerized to protect from elements. Anothe...

I am waiting for even smaller rockets. Motors of which are the basis of A2S rockets and shoulder launched man-portable anti-air missiles.

Beautiful launcher of Army MRSAM. I expect shore-based VLSRSAM launchers to look very similar. May be on a 6X6. The Akash NG will be slewed like QRSAM. Akash NG launcher looks like a trailer type. Although, a more mobile version based on 10x10 is possible. https://pbs.twimg.com/media/EqE7ZHQUwAMgmZP...

It means that SP23, 24 .... are not waiting in an assembly line. But, IAF & HAL have agreed that IAF will not accept and HAL will not deliver a Tejas which is not fully serviceable at IAF's BRD without any of HAL's interventions. And that this serviceability leads to a minimum level of availabi...

Indranil

The delay in delivering the SPs is not because of production rate. Initially, The Tejas squadrons were placed near Bangalore so HAL could handle initial serviceability issues. That umbilical cord is being cut. Indranil, with my limited understanding I fail to grasp the connection. How is this issue...

Indranil

The news is correct. I have known it for about 2 months now. Other potential export potentials are also being evaluated. Geopolitics is involved in decision making. It will be difficult to beat T7 just because it is US's bird. The delay in delivering the SPs is not because of production rate. Initia...

HAL working on converting HAL Kiran into optionally piloted aircraft "Kiran-UAV". I believe this is work which feeds into the loyal wingman program. There will be an Integrated Control Computer (ICC). There will be three actuators for the existing controls. The commands from the ICC will d...

Indranil

I have a feeling that RCI is developing a drone, a sizeable one. It has issued a tender for 8 nose wheel steering actuators and 58 control surface actuators. One doesn't need nose wheel steering for a small UAV. For instance many 2 seaters don't have nosewheel steering. Even if I take that these are...

Indranil

The fuel numbers are correct.

The MTOW I would still say is 17.5 tons. The 18.2 tons I think is for contingency.

Mk2/MWF will easily outrange Mk2. Higher fuel fraction and significantly lower SFC can lead to only one thing. I would say 300-500 kms more in range.

Indranil

More details coming out. 3388 kg of internal fuel. 7148 kg of total fuel. The things that make me chuckle: IB Drop tank capacity is 1360 kgs(not ltrs). And FINALLY, an oval centerline DT carrying 1040 kg of fuel. Bolo, kahaan ghumne jaana hai? https://pbs.twimg.com/media/Ens2e6AVcAAOgbD?format=jpg&a...

SP 23 and 24 to take to the air shortly. Others to follow in quick succession. They were taking some steps so that the availability and maintainability of the aircrafts increase significantly. That's the hold up. Not the production rate. Meanwhile the SPJ pod is getting ready for manufacturing. 8 pr...
