HAL Advanced Light Helicopter Dhruv

Those Rockets are unguided, how are they going to hit something fired at that angle?!.. How are they even aimed?

Same way a Howitzer or MBRL fires.

^^ Ever heard of parabola? Even if its unguided its path can be prejudged. The diff is that with guided rocket you can target with more precision and CEP is reduced but unguided cant be precise but that can be compensated when fired w/o moving.

Same way a Howitzer or MBRL fires.

But for MBRL firing is done relatively safely from dozens of kilometres away after serious calculations, rectifications & powerful area-damage weapons that rarely score direct hits. Attack-helicopter firing puny 70mm rockets under enemy fire is completely different matter!

Serious question:
I understand that parabolic path & point of impact can be predicted. Is that being done? Even then, how are they aiming? HMD? ..do they just point & the launcher-pods move to adjust direction? Because turning the vibrating, swaying helicopter towards the target, doesn't seem a good way to accurately hit targets at long ranges.

Rockets are not used at long range. In the arsenal of the attack helo, its ATGM - FFAR - Cannon in diminishing order of range. Rockets are used for area saturation of infantry groups or soft skinned targets.

For accuracy they use either ATGM or Cannon depending on the target. There are 70mm guided rockets too now available for small target engagement

Such rockets would be unnecessarily costly, when they could just make the rocket-pods moveable.
Just point towards the target to bring it within frontal 20-30° & it could turn, so that the unguided rockets will land where HMD is looking at... operating in same way as the canon.

Rudra attack helicopter.

why is army rudra black in colour and not in regular camo

why is army rudra black in colour and not in regular camo

Same question I am also asking. IAF Rudra has a better camo than IA.

The weight penalty is too high.

Black is better for night ops? Dunno

I think that black looks damn cool. Good differentiator from rest of the choppers.

The weight penalty is too high.

You are saying that based on what? I think the rocket -aunchers on the arms can already be raised & lowered.. even if not, making them slightly movable shouldn't be too complicated.

None of it is automatically movable, that takes motors, gears and power which all has a weight penalty. You would be taking the weight of the gun mount and adding that weight for every rocket pod.

If you can't think out of the box, maybe then... otherwise unmount is far more complicated mechanism.
To just slightly turn or tilt a pod, it could just take a gyro censor & 2 hydraulic-pipes attached to a modified movable pylon. The powering unit inside the body weight be too heavy either.

Laser guided rockets is the only box it needs.

well looking cool is certainly not the reason to give it a black paint job and as far as looking different is concern IAF already has different colour scheme there must be some other reason

A helicopter gunship would for sure not engage a AA battery with a bunch of rockets. As @uoftotaku already mentioned, rockets are basically to saturate an area of engagement. They are not for direct line of fire attack. The range of these 70mm rockets could be anywhere from 6 to 8 km. So you could see that while engaging such a target, it is fairly out of range of any anti aircraft system.

so why army painted ALH dhruve in different colour ,they should have coloured all the rotary fleet black

Wow ! they indeed are meant for line of fire /line of sight attack like a normal MG and is a flat trajectory system. Rockets are not high trajory weapons.

Fair, but one has to see a target to fire rockets into it with the help of a pilot sight. Fired in a forward dash.3-4 km is negligible

Beacuse BSF has adopted Camo pattern. So to distinguish it from BSF...

ITBP and Assam rifle should merge

variety is way of life?everybody likes little color in their life? wait for PRODUCT RED edition of Dhruv - It may also come out soon
