A model of the LOH, has the 'Fenestron' style tail?
Re: LCH discussion
the flat panels might simplify manufacturing , repair and fitment of titanium armour plates around bathtub and
avionics/engine bays.
are helicopter rotors metal or composite these days? if composite they would have no RCS.
hopefully Helina, rocket pods, mistral aam, countermeasures developments can proceed swiftly in parallel. we need 100s of this bad boy.

I have a question
Is the HMD gun 20mm?
Why have they installed a small caliber gun?

Re: LCH discussion
24 attack helis that are required are going to stay for 2 decades , if LCH isnt finalized within 1-2 yrs , apache will be ordered , and that means LCH joins LCA league ,
the RFI is already floated .
Meanwhile LCH has to be better or equal to Apache longbow ,
are they going to fix radar on it?

you kidding? longbow is uber-expensive, complicated and much heavier. if IA goes for a small apache
order I do not expect the longbow version, just the basic one.
we need 100s of LCH whether or not some small lot of apache's comes in.

Re: LCH discussion
Umm why would european patents be necessarily applicable in India? At best it will block us from selling it in Europe? We can always make minor modification and get a patent in India.
In any case we have not reversed engineered it or gotten its detailed drawings.
Let Eurocopter "lagao chakkar" of Indian courts.
And if they really want a cut, let HAL sell the copter to IAF for 1 ruppee.

Re: LCH discussion
Long bow is for the plains onlee, no action in the himalayas sector.
LCH is built to operate at those altitudes - might even go to siachen. Will go to laddakh and NE for sure with good weapons load.
Great going to the LCH team.
Was''t there a plan for the forces to order 100+ LCH's? The attack 24 helo RFP might well end up with Apache Longbow.
Expect some defence realted news when Ombaba lands in Nai Dilli later this year.

you think 24 attack helis is enough for india? the Mi24/35 are getting long in tooth, inspite of getting tamam
upg few yrs back. I think plan is to replace them with something in their hefty category.
even sher khan 1st airborne div alone deploys with 300-400 mix of attack and transport helis into the theatre.

Re: LCH discussion
Sher khan uses at least 3 types of attack helos
1. Cobra / Super cobra still in use with the marine corps
2. Apache Longbow with the regular army formations
3. The light observation + Attack MH-6 Little bird. For close in support to troops.

Re: LCH discussion
NOTAR and Fenestron are not as efficient as the conventional tail rotor something critical for an attack heli which is supposed to operate in Indian conditions whether it be in Jaisalmer or Laddakh/Leh.
Re: LCH discussion
Longbow has two (Counter-rotating?) tail rotors.
The tail rotor has been found to be specially susceptible to small arms / rpg fire, and this one vulnerability exists for all attack helos.
On the longbow there is an attempt to have two tailrotors to minimize this.

Re: LCH discussion
I believe someone posted here many years ago that notar bleeds too much main engine power compared to
the conventional tail rotor which I believe is driven by a shaft through the tail boom?
fenestron - for a while it seemed all the rage like dauphin, but even eurocopter seems to have skipped it
for its latest helis, so obviously some pitfalls must be there...looking at NH90 pic it seems like fitting a
big and meaty conventional tail rotor is not possible with fenestron

Re: LCH discussion
No it does not have a contra-rotating tail rotor , however unlike the conventional 4 bladed tail rotor it has two twin rotors with 2 blades each at 55 deg while in case of former afaik it should be 90 deg between each of the two blades.Gagan wrote:Longbow has two (Counter-rotating?) tail rotors.
Re: LCH discussion
Any specific reason they would have them at an angle < 90? Maybe because of small arms fire?

The LCH has full glass cockpit. Looks neat! Both for driver and the back seat wso. Very nice indeed.

Re: LCH discussion
I think we need atleast 200 LCH. The cockpit layout looks similar to the japanese kawasaki OH-1. Which is thier light attack platform. A 30-40 Apache or Ka-50 would complement a force of 200 odd LCHSingha wrote:Meanwhile LCH has to be better or equal to Apache longbow

Re: LCH discussion
more as a 1 to 1 replacement for the old and aging Mi-24/35's of which we have 20 for the strike corps. btw, wasn't it 22 and not 24 for the RFI ?Samay wrote:then exactly what role LCH is going to perform, separate RFI for 24 attack helicopters means what?
although if the LCH comes along quickly we might see that one canceled, but low chance of that happening.
the LCH is obviously going to be lesser capable than the apache (twice its weight) and similar sized attack helos but it has (or will have) one capability that no other attack helicopter in the world has, namely operating with combat load in the higher himalayas up to 20,000 feet or so. apache and the like can barely fly to those heights, let alone fight !
sensor wise, no it will not have a radar, few attack helos have one but otherwise it will a full spectrum of state-of-the-art sensors, ECM and a MAWS as well. even a DIRCM is in the works !
IAF plans to get 65 and IA wants to get 114, making a total of 179.
20 mm 'gun' is NOT a small caliber gun, those are also known as cannons.jimit wrote:I have a question

copy -pasting a discussion from ajai shukla's blog that I had read long back that should answer your questions :
fighterclass said...
max said...
The other thing I realised is all helicopters in its class / era are equipped with 30mm turret while this only has a 20mm nexter.
___________________________________
not true:
ah-64:30mm
mangusta:20mm
tiger:30mm in french version. no chin mounted gun in german version,uses podded 12.7mm or 20mm.
ka-50:30mm
rooivalk:20mm
ah-1z: 20mm
mi-28:30mm
mi-25:12.7mm
mi-35:23mm
........................
so you see a lot of both older and newer helos do use the lower calib guns.
do note that the commanche also used a 20mm cannon.
One of the main reasons is that at around 5 tonnes, a 30mm gun firing in auto mode would have tremendous recoil, enough to seriously destabilize the craft.
all the helos with more than 20 mm cannons are much heavier than the LCH, in the medium to heavy class. those can handle the recoil better than a light bird like LCH could.
___________________________________
max said...
Although its firing velocity is better, can it compensate the damage a 30mm slug can cause?
___________________________________
of course, a 20mm slug would have lesser damage but the question is what type of targets do you intend to use it upon ?
"BOTH" can shred thin skinned vehicles but is 30mm enough to incapacitate an armoured vehicle ?
hardly !
so what is the use of a heavier 30mm round (which you would carry a much lower number of) if all you are going to do with it is shoot at personnel ! worse, it would also give you a bad recoil to boot !
the 20mm does the same thing without a recoil and you would also carry many more of the stuff !
of course, if you mean that the sheer devastation of the 30mm is unmatched in badness, I'm all with you !!
Broadsword said...
To add to what fighterclass posted above on the choice between "adequate damage" versus "near-assured destruction" --- which is what the choice between 20 mm and 30 mm actually boils down to --- please remember that choosing a lighter turret gun also allows a higher rate of fire.
So you have a higher hit probability with a 20 mm gun, not just because of the lower recoil; you're also pumping out more lead... even if they are in smaller pieces!
And you can carry more rounds on board in straight numerical terms.
Remember, most armies the world over have switched from personal weapons that fired 7.62 mm ammunition to 5.56 mm for similar reasons. "Adequate damage" is damage enough.

Re: LCH discussion
Looks very nice!
The stub wings seem to have positions for 2 hard points each. I wonder if they are considering IR suppressor attachments in the design at all later on, given how the exhaust is pointing up.
What is the % of parts common with the Dhruv - might help ease the logistics at high altitude areas and simplify maintainance.

Re: LCH discussion
it not due to time, LCH is in different class altogether , as the name itself Light Combat it is in the light wight class.Though I don't understand why we cannot replace Mi 25/35s with LCH directly, instead of Apaches/ Ka 50s. Is it due to LCH taking time?
It can not take lot of amo in but the Apache is one big beast same with MI
MI can even can carry combat troops proved that with air support n get them back, can carry lots of amo, the Apache/K-50 are high on maintenance when we compare it to the lighter ones like the LCH
evan as USA has on of the best Attack Helo Apache they still use the
super cobra
MH-6
for different roles

Re: LCH discussion
don't know how to break this to you but they are trying to built an attack helicopter that can fight in the mountains, not trying to impress people.I am not too impressed, hope final version is much better.
apparently IR suppressors eat in the power figures so that's an interesting question. we did retrofit them on the hinds though.I wonder if they are considering IR suppressor attachments in the design at all later on, given how the exhaust is pointing up.
is the lancer still used ? I thought they had given up after terrorists started firing at any helos ?1) HAL Lancer (light attack and observation, for COIN)
2) LCH
3) HAL Dhruv (weaponised version)
4) Apache or Ka 50
you missed the Mi-17 which too can be fitted with rockets.
truthfully, only LCH and the attack helo RFI one would be pure attack helicopters, rest are utility/transport helicopters with an attack capability.
or because the Mi-24's are long in the tooth and IAF can't afford to wait for LCH.Though I don't understand why we cannot replace Mi 25/35s with LCH directly, instead of Apaches/ Ka 50s. Is it due to LCH taking time?
Re: LCH discussion
IDK what you were expecting. It looks same as the models that we have been seeing for some time. To each his own, but I am extremely impressed by it looks. IMO, it is the sleekest heli I have ever seen. And though looks do not matter, the sleek looks of LCH do make this jingo very happy. I really want to see LCH is grey camo, man it will be a looker.Ashish J wrote: I am not too impressed, hope final version is much better.
