DRDO, PSU and Private Defence Sector News

[Chinmoy]

Break up DRDO in the same way as the Defence Ordinance Factory Board was broken up into multiple units with independent management, accountability and mandate. They should have independent service rules, separate hiring criteria and keep the IAS cadre officers out of it. If there is a need, outside scientist be hired to head department and manage the affairs. Then it will be easier to manage them and check their performance and fix responsibility.

Right now DRDO is an extension of a government department with similar attitude to work…..that is pass the buck and take no responsibility.

Only Modi can do it. A lot of leaders prior to Modi thought about it but could not do it.

What is FRP? Fiberglass epoxy?

K4 finally we get to see how it looks like

I don't know who made this, but what is the ratio of those Aero control fins down there? Even in 1:10 model, it looks absurd and useless.

Its the first stage of a ballistic missile, Practically speaking it doesnt even need fins. IG they didnt want to fit a TVC nozzle in this, so opted for fins. More than sufficient for the limited maneuverability needed.

 

[Chinmoy]

But that cruise vehicle looks more like Zircon than HSTDV

And this in turn looks more like waverider.

But yeah, that is a copy paste by DRDO. Design of HSTDV is different from Waverider.

is this the most efficient form factor for hypersonics available currently, hence they all look the same?

 

[Chinmoy]

SAAW, pinaka missing.

other brahmos and akash mk1, most of the work on rest of them happened in last decade.

SAAW is product of RCI and Pinaka a product of ARDE.

So missing from DRDL poster.

Now in that case those fins are no good. Look at the size of the missile and look at the size of those fins. You don't even make such a model for wind tunnel test.
In my guess, this is not even a missile.

May be. Depends on how you want to use it. If we compare these with HSTDV model, we could see a huge difference.

there should be a HD version of that poster with all missiles and rockets (current and planned), it fits the New India's branding inspired by elements of chakra.

Seriously ?

If one could determine aerodynamic characteristics , air flow interaction of control surfaces by just looking at pics than what's the use of all these CFD tools , wind tunnels , hydro basin test facilities ?

Look at the size of the missile and then of those fins.

What volume of air or water you expect to flow around the missile and how much effect you think those fins would have on that flow?

We have already seen our SSMs without aero control fins. So I believe these fins are there to provide stability under water. But in that case too, compare the size of the missile and its weight and then the size of those fins. Are they adequate enough to decide on the steering of the missile?

It could be a botched up image. But I don't believe the final product would be anything like this.

I'm not accusing DRDO of copying others designs, I'm only asking whether it's the actual design or just representative one

By looking at pics one cannot determine the aero/hydro dynamic characteristics/performance

IMO there are not for steering underwater, K4 travels inside a bubble created by the pseudo 1st stage (nose cap) which starts firing once it exists the submarine silo, it barely travels <100m underwater ( will not give the exact depth)

Those fins are required for aero dynamic control during the low dynamic pressure zone experienced post exit from water till the time the pseudo 1st stage burns out at a predetermined altitude

After that the base shroud at the bottom of 1st stage with the control surfaces are discarded , which than allows the actual 1st stage to fire and then the FNC (flex nozzle control ) of now burning 1st stage starts exerting thrust control

Any idea when our Bmp2, or T90s will be upgraded. Hearing about this for almost a decade and still not even a decent prototype of upgrade. And if recent reports are to be believed IA seems to have shifted the goalposts again on systems involved for modernization.

When they will lose or again barely win after many unnecessary sacrifices,
In my opinion .
Then new plans will be drawn for next 40 years .

Both are going on. TATA is involved in T-90 upgrade.

 

[NoobWannaLearn]

@Chinmoy bro any update on any kind of our uavs or ucavs or project cheetah?

 

[Love Charger]

Both are going on. TATA is involved in T-90 upgrade.

Sir you are knowledge able, just tell me are they upgrading the gun and ammunition also ?

 

[jai jaganath]

Are they upgrading protection I mean new era or aps
