Apache does not have refueling capability..?Helos don't need to move with the unit. They can operate off semi-prepared areas 25 to 50 km behind the lines and still be as effective and less vulnerable and will not need a dedicated number of men to protect them and maintain them and lug them around in the front lines. They can also be used exactly where needed and if they are not needed immediately for the unit that is lugging them around in a truck. It does not make sense to treat helos like mortar or tanks.

I assume, you mean Air to Air refueling capability?prithvi wrote: Apache does not have refueling capability..?
If so, then yes. But Attack helo's of the Apache's class rarely need to go out for a long distance trip unless when ferrying within a theater and they are generally deployed about 80-100km behind the front lines so that they are close to the action but not that close that an accidental breach by enemy forces can put them in a big risk.

Re: LCH and other Helicopters Discussion Thread
Philip ji,
what you say has a lot of merit. the Air Force guys usually look down on "support" roles and operations which involve giving extra muscle to land forces. this is a problem that a lot of countries face. even in US you have AF guys fighting fiercely to stay out of "control" of Army guys. this is an ego problem. the ideal solution would be, to let the Army have its own dedicated air wings so that their operational tactics are geared strictly around Army doctrines and focus areas.

How does this digital camouflage work better than a traditional camouflage paint job and in this instance, why have the white & black colours as part of the colour scheme, rather than green and brown?
If this is done to make the helicopter difficult to spot on the ground, then shouldn't the rotors/wings too be coloured in the same scheme?

What exactly is the 'technology' when it comes to digital camouflage paint? - Is it not similar to painting a closed set of abstract shapes made of small pixel like squares?The LCH TD-2 was the main draw at Aero India 2011 wrapped in digital camouflage paint -- a technology mastered by India recently. Incidentally, LCH will be the first Indian Air Force asset to don this new paint scheme.

Re: LCH and other Helicopters Discussion Thread
There needs to be a conscious effort to reduce dependency on imported arms, especially when an indigenous option is already available or is in the horizon. If we do decide to buy the AH64d then the deliveries will start only after about 4 years, which is probably enough time for the LCH to mature. It is best to scrap the competition. And if the problem is not time but some inherent short coming in the LCH then they should scrap it instead.Singha wrote:like any new platform, LCH will take its time to mature. even its atgm helina not even flight tested, so looks like we might be going the pars route there if helina doesnt come up soon. the Eurocopter tiger has been in "service" for years and even exported to australia but was not complete enough to even enter the flyoff for India. same for Mi28N - I have been hearing of the night havoc for a decade now...took time to enter service.
whatever be its demerits the AH64D is ready now, with a complete family of weapons and combat proven even at high altitudes ... so its a ready-to-go soln vs LCH which will likely take another 5-7 yrs to reach its full potential. given its cost I dont think we will afford more than 50 ever. most munna's have a bare dozen to show off each.

Re: LCH and other Helicopters Discussion Thread
I am not sure this is right way forward. While indigenisation is important but not at the cost of combat edge. I think IAF would have different roles in mind for AH 64/ Mi 28 as compared to LCH. To this point, I am trying to understand the role of AH 64/Mi 28 vs LCH in the IAF. I assume that IA will not be operating heavy gunships. I tried searching on the Google for different roles but no substantial results. In fact, during the search one of the article showed the limitations of gunships in mountainous terrain. So gurus please show some light here!abhik wrote:There needs to be a conscious effort to reduce dependency on imported arms, especially when an indigenous option is already available or is in the horizon.

Just shows the limitation of helicopters to Manpads and small arms, I believe even prop driven fixed wing aircraft are a cheaper and more effective option vis a vis helicopters

Wondering why we are not looking at lighter versions of v22 sdre ospreys? Given blue water needs, and ADS getting done is imminent, the sdre ospreys can do wonderful job for IN.
Is the design too risky?

Re: LCH and other Helicopters Discussion Thread
osprey also need a giant footprint on the deck to land safety - kind of like two large helis landing side by side. in a emergency , a normal naval heli could land on any FFG/DDG around, not so the osprey I think.
the Merlin AW101 also cannot land on FFG decks due to its size methinks...on deck of arkroyal it looked like a outsize kind from class6 sitting with the class1 kids.

Re: LCH and other Helicopters Discussion Thread
No weapon system on it's own is invincible - tanks can be destroyed, aircrafts shot down, ships and subs sunk etc in a war - the point is this is why dedicated tactics and strategies are drawn for the employment of each weapon to capitalize on it's strengths and minimize losses due to it's weaknesses.shiv wrote:Great link and a must read for armchair marshals.rohankumaon wrote:

Also, not every weapon can be successful in each and every theater of war and if a commander still goes ahead and employes equipment and troops even in such scenarios you can not say that the equipment was not good.
Re: LCH and other Helicopters Discussion Thread
the point was not to prove the apache as vulnerable, but to dispose off the myth that it can do deep strike into Tibet on logistical/C3I nodes. I now realize its just too risky and wont happen based on what happened over karbala...a strike a/c can do it far faster and safer and put more bombs on target.

Re: LCH and other Helicopters Discussion Thread
a case of a solution designed and tested in indian conditions no doubt.
one example of a good product whose "behaviour" was designed for developed countries is the humble but reliable APC UPS. over there, the power going off is a major "incident" so they trigger a loud and annoying beep beep beep that keeps on howling till the charge is over. over here, power goes on and off, so this is a major mosquito bite esp in middle of night when ur machine is doing a long download and you left it on. the lowest model has no way to turn it off other than perhaps dismantling it and cutting the speaker if it exists inside. the higher models have a linux pkg that connects via USB intf and can be turned off..no easy UI or switches.

Re: LCH and other Helicopters Discussion Thread
Tell me about it. The annoying beep, beep is truly something that bugs me no end. I'm so surprised that this isn't customizale. LCH no doubt will have indian solutions to uniquely indian problems.

A type flying below or just about the tree-line in plains or below the ridges in mountains will be near impossible to find out - but for good radar. Now, imagine this chopper hugging the tree line in western sector in Punjab and hovering low before popping up to launch a LOAL ATGM. Nice!
Re: LCH and other Helicopters Discussion Thread
Now, I have to see LCH, loaded to bear with helinas.

Re: LCH and other Helicopters Discussion Thread
why does an underdevelopment craft require such intense camouflage?
During this phase, when there is a higher chance of accidents, shouldn't the plane be easier to spot rather than making it more difficult?

Re: LCH and other Helicopters Discussion Thread
Well they might be trying to see the effect of these paints on the weight of the bird. The weight of paint on the birds generally in hundred plus KG's. Also they may be trying to see the effectiveness of the camouflage scheme itself.AdityaM wrote:why does an underdevelopment craft require such intense camouflage?

Just my guesses. But if HAL and NFTC decided to leave them on then there must be a sane reason for the same.

- How do you test camouflage on a non flying aircraft?
- They have reduced the chances of accidents by getting TD 1 right and are testing the camouflage on TD 2.
- Test aircraft are always under telemetry unlike an aircraft flying over mountains, jungles and oceans - so the search requirement is not necessary.
- How is a totally shattered and burnt bright orange "glow in the dark" aircraft easier to see than a burnt and shattered camouflaged aircraft?

and earlier one talking about Sikorsky X2:
http://www.economist.com/node/16990748
What Osprey tried to do was make a prop plane into a helicopter. The helis are now trying to integrate wings and propellers into their design to increase the speed and range. We are likely to see weaponized version of these in the coming years.
Re: LCH and other Helicopters Discussion Thread
you're talking about the weight of paint on large sized commercial or military transport aircraft.Bala Vignesh wrote:Well they might be trying to see the effect of these paints on the weight of the bird. The weight of paint on the birds generally in hundred plus KG's. Also they may be trying to see the effectiveness of the camouflage scheme itself.
you can refer to weight penalties on a commercial Boeing aircraft on this Boeing page
On a narrow fuselage LCH, the surface area will be much lesser than that on any of these commercial airliners and the weight of paint will be much lesser.
For instance, even the smallest airliners in that list, i.e. the 717 and MD-80 will have significantly higher surface area of the LCH in their fuselage alone and the weight of paint on the upper & lower half of the fuselage and the tail is only 119 lbs (54 kgs).
So this is definitely not to check the effect of the weight of paint.
Re: LCH and other Helicopters Discussion Thread
I may be wrong but here is what I think it is........
This digital paint scheme is primarily for reducing IR (& may be others) signature of the aircraft, visual effects are secondary concerns. White doesn't absorb/emit EM specta and blacke/darker part does, so this change in color on skin breaks the thermal signal into hundreds of small pieces of cold and hot signals, instead of one giant integrated IR signature. These small signatures would be a lot more difficult to stich in one piece by thermal/IR sensors. That is why it is called digital cameo, once you have digitized signal and developed a model, computers can generate different models for different environments.

Re: LCH and other Helicopters Discussion Thread
At the resolution at which an IR sensor would see the chopper, my guess is you would find one smooth (but not so bright) image
Re: LCH and other Helicopters Discussion Thread
when we say visual camouflage, what is the expected enemy line of sight are we talking? from a point at higher altitude and the camouflaged target is lower and against the ground colors? or from sky to sky facing the horizon or from bottom to top facing the blue or grey or night sky?
