Indian Army Artillery Systems : News and Updates

Defence contractors work as per SQRs. Who issued them & how did they arrive on those findings ? ATHOS is lighter . Ofc it is . If I DRW is to be believed it's because ATAGS is equipped with electric drives which makes it heavier.

Yet there were hundreds of reports when the IA regained interest in procuring the ATHOS under emergency financial powers highlighting this feature conveniently neglecting to inform about the different drives used resulting in weight difference, in support of the IA's choice .

Whom do we believe now ?

Lol. Goes against conventional wisdom yet multiple sources reporting the same findings. Also goes to show repositories of stories & skill in storytelling have nothing substantial as proof to offer or refute except regurgitating conventional wisdom.


Weight​

The hydraulic drives are comparatively compact for the similar torque requirements and thus the overall weight of the system is much lower. One of the criticisms of ATAGS is the weight of that system. Howitzer weighs a whooping 18 tonnes but it can be justified with the range and firepower it offers.

The use of Hydraulic drives will certainly reduce the overall weight of the system. Thus, operationally guns can be towed by artillery tractors of lower power ratios. This also has an impact on the overall fuel consumption during a typical towing rally.

Compactness​

Electric drives can generate incredible amount of torque without the losses associated with torque-multiplying gear systems. The problem is that the size of these high-torque electrical drives is unworkable for use on heavy equipment. However, in ATAGS torque required is not comparable to a typical heavy haul application. On the other hand, hydraulic drives can generate almost equal amounts of torque at a fraction of the size, but with a penalty of efficiency. Some hydraulic drives have been specifically designed for high torque and power density applications. If there is limited space for a high torque motor, then a hydraulic motor would be best.

So, this drive change will make ATAGS more compact and lighter, but its operational efficiency will suffer.

Conclusion​

Overall, this change will certainly make this gun more aligned with the requirement of the Indian army. The gun will weigh less, it will cost less, and will be much easier to maintain. However the accuracy of the gun might suffer a bit

Generating Torque​

Electric motors can generate tremendous amounts of torque without the losses associated with torque-multiplying gear systems. The problem is that the size of these high-torque electrical motors is impractical for use on construction equipment. Hydraulic motors can generate equally tremendous amounts of torque at a fraction of the size. Some hydraulic motors have been specifically designed high torque and power density. If there is limited space for a high torque motor, then a hydraulic motor would be best.

Hydraulic Motors vs Electrical Motors: Why Hydraulic Wins

While electric may certainly be the right choice for some things, we'll generally stick with hydraulic for the dirty work in heavy equipment. Learn why!

Disadvantages of Electric Motors:
These motors are complicated to install and troubleshoot compared to other motors. Mostly, their disadvantage is that if you need a lot more force, you need a significantly larger and heavier motor, unlike the case in hydraulic motors.

Differences Between Hydraulic Motors & Electric Motors

The hydraulic vs. electric motor question has become a more urgent one in engineering following rapid advances in electric motor technology. Hydraulic motors allow for terrific force multiplication in small spaces, but are messy to operate and also more expensive than their electric counterparts.

According to Snehesh Alex Phillip, ATAGS are due for final trials later this month , post successful completion of which the order placement formalities should commence.

Unless in house story teller has more trials - summer winter monsoon autumn spring etc in Ladakh, Cherrapunji , Pokhran, Deolali ,
A& N , Arunachal Pradesh etc planned or Snehesh A Phillip is storytelling himself or something goes horribly wrong during final trials, that should be the end of a 10 yr old saga.

Boost for indigenous firepower: ATAGS set for final trial, Dhanush clears fresh firing test

Dhanush needed fresh trials after Army flagged production quality issues. Advanced Towed Artillery Gun System was found to have 'inconsistency' in overall performance in trials last June.

Okay, okay, my loss. Electric drive is indeed heavier. But weight is a different issue, it won't lead to failure in trials, especially after completing mobility trials. The problem was in the drive itself.

But it's 2022, so things work out this year.

Anyway, last year I had said that trials are not complete. If they fixed the issue with the electric drive, then this round of trials should deal with it and complete the trials.

But since it's 2022, it should work out and the army should be able to place an order for LSP. 2022.

We Are Hopeful Of Not Only ATAGS To Be Inducted But Garuda And Light Weapon Also—Baba Kalyani, CMD Bharat Forge

Kalyani Strategic Systems, the defence arm of Bharat Forge is aiming to be the leading Indian OEM of the world in Defence & Aerospace. KSSL is developing an entire range of field Artillery for Army: Bharat 52/ 45, Garuda 105 and ATAGS with DRDO. Fact that in decades, Indian Army could only...

Happy to see Kalyani being so confident about the tech he's working on.

Makes sense that they have decided not to import ATHOS.

Damn! My heart sank after I saw that prototype for the MGS being developed by DRDO. Looks like a mechanical dumpster in service with the Municipal Corporation of Mumbai especially the hideous looking body of the gun protruding from the rear.

For a moment the thought occured to me it's something story teller would have developed were he in DRDO then bragged that as a finished product it would have better aesthetics ( not abilities, for he'd keep quiet on that) than BAe Archer . If it failed user trials he'd turn back & say it's the aesthetics which compromised the performance. So we'd be back to square one, no questions asked.

Jokes apart I wonder why can't they take design tips by looking at European or US make MGS & replicate it here or is that too much to ask for?

Which MGS has DRDO developed? OFB has developed an MGS based the Dhanush gun in 52 caliber and mounted on a BEML made Tatra truck.

That one is an OFB product not a DRDO one.

Kalyani one is there too. Hopefully they are working on the 52 cal version too.
