Probably they are subsidizing the whole BMD program with this commonality of missile components, once PDV is launched we should see a similar looking surface to surface version with longer range following Another criticism of BMD being expensive down the drain if the liquid fueled Prithvi was ineffi...

choti mooh badi baath, Are there plans for a removable, retractable, refueling boom? which seems to be a low hanging fruit in the overall feature set and for handling gun recoil, the following concept may be helpful http://wiki.answers.com/Q/How_the_speed_breakers_are_useful_for_the_generation_of_el...

for aircraft carrier design why isn't the LCS trimaran design is being considered? for example a mistral sized ship at the center flanked by longish corvette type vessels on either side, the flat top overlays all the three with a deck underneath allowing for flights to be parked inside. Here is how ...

if one were to attach the huge solid boosters meant for the GSLV flight to the PSLV, even if its not optimal, can they lob heavier sats? since waiting for optimal solutions will mean delays cryogenic stage isn't mandatory if the sats are able use thrusters abroad them for GTO to GSO transfers like t...

With the shortage of transponders, thats where they should head and whatever manufacturing practices they did for mass producing those Iridium sats should be adopted. Congrats ISRO!

This cooperation should extend to hybrids in the auto sector, reducing metro area pollution in our cities, specifying emission standards, hence carbon credits and at the same time convincing Japanese on the non-fossil power requirements to support the hybrids in the Indian market thus finally conver...

why is the foresight of co-opting Sri Lanka with an order of Coast Guard boats being applied to South Korea with an order of trainer aircraft? building a trading relationship (not just buyer's) and then taking the pearls back to the Chinese? The euro-fighter program is also showing up on the radar o...

^^^ At 70 planes on a single carrier, they have enough inventory to provide escorts to their AWACS aircraft, if IN is buying those Hawkeyes, at 25 fighters on a IN Carrier, can it afford to provide dedicated escorts Those 7 hour sorties do show the endurance of even Naval fighters, wonder if they ha...

Secondly the MiG 29 is a plane designed for speed and agility. Neither supersonic speed nor agility are required for an AEW that is not going to be dogfighting over enemy territory. It is poor design to design an AEW radar into a supersonic agile fighter. Third, the workload. if the pilot has no wo...

a UAV works better So the crew are a waste of time and space then? An Aerostat would be cheaper and you could use 10 of them at different places for the price of one of these. And about the wacko-aew, the tail plane can be made with RF transparent material like composites so that Transformers can b...

After Arya Sumatra's objection to the radar being really close to the pilot, a UAV works better so here is Nishant, http://www.bharat-rakshak.com/LAND-FORCES/Army/Galleries/Mod/Logistics/UAV/0678.jpg.html?g2_imageViewsIndex=1 a brand new UAV with a boxy airframe like the Nishant that is capable of c...

How does the Hawkeye compare to the Erieye radar in terms of range? if a smaller RAT will be enough to power either radar

Brahmos required the MKI airframe be strengthened, so even the Mig-29k will have its weight limitations which can be worked on the CABS radar is inclined vs the flight body and is mounted fairly high so the 2nd mount point can be designed to be folded while take-off and elevated above the tail heigh...

vasu_ray

Shiv, the plan is to mount it on the spine of the Mig-29k, one mount point behind the pilot and the 2nd mount point somewhere close to the tail piece, not as a under slung pod probably a single seater, the 8-9 metres is like the length of the brahmos which is shown to easily fit between the intake-e...

vasu_ray

while you guys are on this topic, what are the issues with mounting the CABS AEW&C radar on the carrier based Mig-29k trainer version with some high speed data links to the carrier for additional operators?

vasu_ray

if anybody is interested, Would like to know about HAL's plans for FAA and European certification for Dhruv, they have been saying it for sometime now

LSP-5 flew with an autopilot, how close is Tejas to fly in an Unmanned mode given that lot of telemetry setup already exists?

vasu_ray

Reading up the news, recently Saraswat was saying that 2 new engines are in development, which I think are 1) Turbofan for the subsonic cruise missile 2) Another engine for a loitering missile so it could be the engine from 2) or the Kaveri for our own UCAV, being an unmanned platform it lends itsel...

vasu_ray

Thanks guys for the rationale, on the question of why 1) Technology demonstration and the long lead times usually associated with new development 2) Replacement for the Harriers 3) Based on the pet theory that if North and North eastern air bases are unavailable during conflict, these jets could eas...

vasu_ray

ok, lets take the Pegasus engine, do you think we can catch up with integrating it on Tejas? and have it perform better than the Harrier

we are only considering the FCS, intake and fuselage changes, not engine manufacturing so all under desi control

vasu_ray

Sai, the problem is big enough that we can fit multiple elephants (solutions) in the same room anyways, about the F-35 STOVL the good thing about that life system is its bolt on, the downside is its patented and the engines are still facing problems during testing if Navy has a need for STOVL aircra...

They were doing good with ALH, wonder what happened with Tejas assembly. my vote is for private sector as well

Now, HAL should expand on the ALH assembly lines

Thanks Kartik for answering the question on the use of Titanium few observations, NFC helped in using Ti based hydraulic parts for the Tejas landing gear, There is a video of a bulkhead of F-22 carved out of a Ti alloy block if its weight vs. cost I wonder what would be the design team's choice.

This University interaction should extend to turbofans, turbojets etc as well, currently only known efforts are the Kaveri and the Wankel engines for Nishant. The manned vs Unmanned aircraft ratio might go up in the next decade heavily in favor of the latter

5) Can the fuselage bulkheads selected for the CFT fittings carry additional loads or will they need bulking up? They'll most likely need bulking up and that adds structural weight that will be carried everytime, whether CFTs are there or not. This will require significant work. Are the bulk heads ...

Now that we are past IOC, will each weapon test require clearance from CEMILAC on aircraft flying readiness? the 4 production ones coming online this year should definitely not require any such clearances picking up the pace of testing

Say the stealth aircraft are after targets, CAP can be maintained by IAF with the UCAV or UAVs forming the outer ring, the inner ring by manned aircraft and the innermost by the mobile SAM system UCAVs are small in size carry AAMs and an IRST enslaved to the manned fighters flying the inner ring the...

A simple minded question, can the Naval Tejas's wings be folded at the wing root when they are positioned inside the hanger of a carrier

vasu_ray

A SARH missile works by the way of homing on the radar reflection off of the target, with Stealth the target has its RCS decreased, so an AWACS sized radar can be used to paint it and the MKI's radar will track the VLO based on the reflection only and in this mode as long as the MKI's detection rang...

Its most likely situation specific, in the scenario that Vivek described there was this head-on approach and then a 6'O clock position so at some point the GLCMs crossed the Mirages, now if the Mirages timed their merge they could be right behind the GLCM salvo flight, is that the immelman loop? you...

Unmanned Dhruv

http://www.flightglobal.com/articles/20 ... dhruv.html

hopefully they add AEW radar panels alongside the Dhruv's tail boom for surveillance missions

Can the M-2000's not use their guns in the 6' O clock position? the merge might get them real close to the GLCMs

Is there an update on the immediate plans for the Kaveri Marine Gas Turbine?

vasu_ray

They can plan to have a OTH radar network by installing HF towers at each of the 46 coastal surveillance stations along the whole coastline, this radar network with a range of 2000-3000km will help in monitoring the high seas SAR by the way of networking these stations allows for all weather capabil...

My wishlist would include a) sats for real time monitoring of the ionosphere changes for assisting the OTH radar network b) where the Iridium sat network failed economically we could breakeven and fare better due to lower launch costs, perhaps the Avatar will soon become a reality c) at a commercial...
