Thanks.
so it is a solid ring, i thought it was seeing a optical illusion because of the rotation.

What's the need to increase the drag?

I don't the exact reason

I believe it is to reduce Max and min range , for a flatter trajectory , to reduce dispersion etc

 

[Killbot]

Who needs that shit? Even if the bullet doesn’t penetrate, you will die of its kinetic energy transferred to your body that will shatter your ribs and internal organs might disfunction.

It isn't meant to stop .50 or .338 Lapua. But you can reliably stop anything up to .300 WM probably.

So these are enhanced Mk1 rockets with a 25 percent more range and a 5 year higher service life . So that's a 46.8 km range.

what about accuracy ?

 

[porky_kicker]

I kind of realised something in the last few days....

There is the RUDRAM series of missile family as we all know

And I believe there another unnamed series of missile family of which SMART is a member.

( And then based on little available information there also seems to be another series of missile family based on LFRJ )

Enhanced version of PINAKA Rocket System successfully Flight Tested

Enhanced PINAKA rocket, developed by Defence Research and Development Organisation (DRDO) has been successfully flight tested from Integrated Test Range, Chandipur off the coast of Odisha today, 04 November 2020. Development of Enhanced Pinaka system was taken up to achieve longer range performance compared to earlier design with reduced length. The design and development has been carried out by Pune based DRDO laboratories, namely Armament Research and Development Establishment, ARDE and High Energy Materials Research Laboratory, HEMRL.

A total of six rockets were launched in quick succession and the tests met complete mission objectives. Rockets tested have been manufactured by M/s Economic Explosives Limited, Nagpur, to whom the technology has been transferred. All the flight articles were tracked by Range instruments such as telemetry, radar and Electro Optical Tracking Systems which confirmed the flight performance.

Enhanced version of the Pinaka rocket would replace the existing Pinaka Mk-I rockets which are currently under production.

Notice the drag rings Which may help to strike the other side of the mountains , by creating drag and thus can implement a flat trajectory . May be a clear sign for Chinkies.

Indian soldiers stationed in eastern Ladakh will beat extreme weather by wearing a state-of-the-art dress that comes from America to escape the severe cold. The first consignment of special clothing from the US for Indian troops has arrived in the midst of a border dispute with China. These clothes will help the Indian soldiers to remain stationed at the border without difficulty even in the severe cold. An Indian Army soldier wearing latest American extreme cold weather clothing for braving winters in Eastern Ladakh & carrying recently acquired Sig Sauer assault rifle Army is providing new habitats & clothing to soldiers to help beat winters during deployment along China border.

I hope we cancel AK 203 and go for Sig 716 instead.

Buy oranges instead bananas, wow!

we should buy a 5.56x45mm NATO Kalashnikov platform!

Drag rings

Wouldn't drag reduce the max range or conversely require more solid propellants to cover the same range.

They could have used canards to create drag only when required without restricting the max range.

In real life unguided projectiles loose accuracy at long range as test conditions and battlefield conditions are never same. There are penalties which one needs to make a call on.

Rockets have fixed impulse , the thrust cannot be throttled nor it cannot be stopped as desired. Range and trajectory control is very tricky and difficult.

Drag rings are added ( easily screwed on or off ) as per operational requirements in the field to induce controlled drag for reduced range , flatter trajectory , near reverse slope targetting etc.

Fixed canards generally creates more lift than drag.

Drag rings have been used in unguided rockets , shells etc since last 50 years or so for achieving desired range , trajectory shaping etc . If max range is desired then drag rings are not used.

Wont accuracy be affected at max range. Since drag rings are removed. Or there are other ways to control it

Is this not SANT?.. Are both same?

You should make a chart of all our ATGMs. It'll spread all over Internet.

Even though MK1 enhanced has drag rings and shorter in length still it has almost similar Range due to more efficient propellent grains and the accuracy is better . If you see the Guided Pinaka it has Fins it's front section , this will basically improves the range and accuracy in plains , but this one is specially designed for mountain areas for striking the reverse slope drag rings are the suitable option for this .

Canards are there in guided Pinaka for active trajectory control. The guidance section will use them to actively steer the rocket round to remove the drift and dispersion at range .

The solid propellants used in guided Pinaka has been ported back to the enhanced one. So it has longer range despite having a reduced length.


So, we can be certain that pretty soon we will have a few Pinaka regiments attached to the mountain strike corps plus some going to independent art brigades .

@NeXoft007

And how many missiles are in each series?

Yeah. Induction of drag rings are done generally to make the system operationally accurate in mountain. Moreover yesterday's test was done with a higher launch trajectory.

Why is everyone so obsessed with AKs?? They aren't that good. Most are overpriced. An AR 15 in same price range as AK will be much better overall.
