I just had one question bout the LCH , have the Laser, Radar and missile warning systems been installed????

Because unlike the Rudra where you can clearly see these attachments, but on the LCH (even in the pic included), these attachments seem to be missing.

If I am not wrong for a combat helicopter that'll be flying at low altitudes in hostile environment these systems will mean the difference between life and death.

If these have not been installed can anyone give the timeline for installation, because without these systems these platforms cannot be expected to be combat ready

Nope!

Production Helis will be equipped with LEDS protection suite which has MAWS as well, same as Rudra as told in one of interview.
Now on DIRCM, HAL was indeed testing(confirmed in HAL report) Elbit J-music with the LEDS MAWS, don't know if successful or not, maybe forces haven't ordered integration of dircm, integration issue or simply not available yet.
Now on RADAR, IA does have requirement of fcr for Helis (as stated in army annual compendium, where various services within army asks for indigenous solutions from industry for products), Rudra or LCH is not clear for which one but likely LCH. Now, HAL is working with someone for such a radar is not known but likely and also confirmed by SJha on his DDR indigenous appreciation hours. Will take time to develop a MMW radar with rotor rotation decoupler as these are new tech different from currently developed which are fcr, surveillance and battery radars, likely with DRDO or foreign partner possibly Elbit.

Hi thanks for the update really appreciate it.....

But as a follow on question at the moment without these things jutting (MAWS,LWS,DIRCM etc) out of the airframe it is a clean configuration and thus we have all the performance measurement (eg: weight, speed, payload, max altitude, range etc)

Now at a later date when we add all the gizmos wont all the critical parameters mentioned may change and wont it have to go in trials again to prove all the changes ??????

I have no aerodynamics knowledge but just with common sense I do assume that adding all that will hamper its aerodynamics (drag especially) and hence the other parameters. So I assume other rounds of trails will take place and no bulk order will be given anytime soon 😢😢😢😢😢😢

So if you see the above pic which is a very early infographic by HAL(around 2015 or maybe early) ,all the systems and weapons were already preplanned and were accounted with permissible ∆weight at design stages itself around the shakti engine. So this resolves your weight issues.

Helicopters often get upgraded with different self protection suites in their lifetime even apache with totally different placements for sensors with hardly any performance penalties as long as there is ample power for them and are placed optimally. So I don't really think there would be a problem regarding aerodynamics, maybe few quick tests. Remember it is not a plane flying supersonic.

I don't really like to talk about specs as no single clear picture is out there. Like ok there is your max payload but at what fuel fraction at what altitude? What is the range for certain weight profile? What is the max altitude achievable at this payload config? Are the stub wings/hardpoints designed to handle such payloads? How are your engines designed to perform in conditions like hot and high altitude conditions? Since there is no graph and no data tables for lch or say any product, debating on specs is total tomfoolery for me!!

LCH has just so much to offer. When HTSE 1200 becomes available you can maybe increase payload or fuel capacity, maybe a little fuselage design change or conformal fuel tanks for that?? You can add FCR radar and its power requirements can be met with increased power of htse 1200?? You can add better sensors or better, indigenous ones. You can add data links for network centricity and add drone control like ah64e, perhaps a drone launched from lch for battle damage assessment and ISR. Add standoff weapons, thanks to targetting data from drone. Make naval lch with foldable blades for future navy lhd ships and marine battalions.

You see a lch which is extreme light weight in it's class with a good engine(htse 1200 power class
) offers performance like bigger attack Helis at reduced cost albeit at reduced level of ballistic protection.

This was on just recent latest official Hal lch brochure. If they don't add quad atgm on inner pylons, I'm gonna be really mad :frusty: . And for god's sake also use 19 tube lightweight rocket pod too,atleast inner pylons are capable to do so. Lch can do much more than what it is currently configured to do. It can be more of a medium class attack heli. Light heli imo are like armed versions of Kiowa, aw 109, bo 105.

Dumbest take I have ever seen. No shit UAVs can only operate in Uncontested air spaces, you think Azerbaijan would have been able to use their Turkish drones if Armenia had air supremacy in the region?

MQ9B is a highly advanced platform , the sensors and capabilities are unmatched by any other UAV in its class. NO ONE said it cannot be shot down.

I would like to see these geniuses suggesting the alternative UAVs to these.

You mean in the actuators? Could be. Its just that its not a conventional structural material, so they'll have to test its endurance first.
The wings and stabilizers of a plane undergo massive structural stress and strain during take off and landing. Along with that, the landing gear door also face those in its life time more then anywhere else in the whole structure. These metamaterials could be used in those portions both externally and internally.

70% of stealth in AMCA has been achieved by geometry and rest would be achieved by RAM. Now RAM would only cover the areas like joints, engine intake, canopy.

The material in question is not the material of choice for those structural parts. Your material needs to have endurance strength for it. What is the SN curve for this material?
Then there is also the issue of strength to weight ratio, production costs for making bulk of this material, etc.
Overall this is a new material. Lets first test it for the application before declaring it fit for it.

I only replied to your query about where we could use this material. I never said or infact even I've not heard ADA saying anything about using this particular Metamaterial in AMCA. But if they have decided to use it, the it must have undergone required tests. Talking about results, you are not going to get it easily on public domain. Overall, this is not the first self healing metamaterial we have developed. IIT-K developed one for strategic implications in collaboration with DRDO. The specs and result of that has also vanished into thin air.

So whether we use it in AMCA or not, we might never know. But if we would use it, then those are the areas where we could see its application.
