New DRDO projects

[Enquirer]

Finally an absolute confirmation that Manik engine will be used on Nirbhay! (flight within a year!)
That Trishul dude can go screw himself......he's been peddling the story for 2 years that Manik is not for Nirbhay!!!!

What an arrogant bastard this Trishul asshole is!! Even after the Director and Joint Director of Nirbhay project stated on camera that Manik engine will be used in Nirbhay (and test flown within a year), this Trishul asshole is claiming that since GTRE didn't make that claim about Manik (& the fact the he didn't know about it earlier) the statement made by Nirbhay's project directors is untrue

So according to him Manik should be some paan brand . He is an ass, claims to know everything. Links every Indian made equipment to some foreign companies. Ask him about arudra, believe me you will be entertained.

Nirbhay is with submerged intake.

Did you do this yourself????????????????????????????????????????/

Absolutely brilliant work !! I just wish the Nirbhay was a bit more stealthier in shaping.

If I give you the wind tunnel model of a missile , will you be interested to reproduce it ?

 

[Aashk]

Nirbhay is with submerged intake.

Check out I engraved it as ALCM
And that's why I said "interpretation " ( background images)

 

[Aashk]

Did you do this yourself????????????????????????????????????????/

Yes, actually previously also I did some work on Astra mk2 (my DP now )
I would have done a decent flow simulation if dimension were at hand

Yes sir, absolutely only can't give you an exact timeline of product, little busy these days, DM s

Thanks, will start work ( without sub systems)

Have you seen the newer Shaurya launcher with a single hydraulic arm ?

View attachment 34520

And some presstitudes were claiming that Shaurya is not deployed. Lol

I have always wished that a long range anti ship missile variant is curved out of this missile.

 

[porky_kicker]

Long time back when the SLS pictures were released , I had speculated in the DRDO thread that these launchers are under deck launchers with integrated below deck reloading system. Many refuted my assertion.

If one expands the picture above ( HMI panel for the SLS floating range ) and notes the words around the indicator lights and push buttons , one can arrive at the same conclusion.

Eg top right " deck hatch " with open and close indicator lights.

Also this SLS is a possible contender ( using the developed technology ) for Indian container based missile launch system much like the Russian club K container system

Would have loved to see one too , imagine a 6.2 ton missile with a 1 ton warhead hitting a ship at hypersonic speeds of mach 7.

But there are technological hurdles on our side to overcome , eg how do you provide navigational updates to the missile moving at mach 7 . Also too much heat generated around the body > 700 degree C , need high tech conformal comms to maintain data link for navigation updates and overcome localised distortion etc.

Chinese ASBM is a hype and psyops.

We might see one in the future though based on the experience from Shaurya from DRDO when technology allows the same.

 

[Vorschlaghammer]

Don't know if this is too much of a conspiracy theory, but the Chinese DF-21 and DF-26 ASBMs do look a lot like the Pershing-II, which did have a terminal active radar seeker.

Back in the 80s, China and US were all lovey-dovey enough to work on joint projects like Jaguar tank, and unconfirmed reports say the J10 is derived from IAI lavi design. Whether the US supplied them with Pershing blueprints or not, is upto anybody's guess.

The challenges of high-speed flight
Propulsion

• Propulsion configurations that are efficient at high Mach numbers are not efficient for low Mach numbers. A compromise in efficiency or a hybrid system is required to operate across a wide flight envelope.
• Hybrid engines or rocket boosters are a possibility, but they are mechanically complex – expensive and heavy.
• Various propulsion options exist. As mentioned above, a combination of two may be the best answer:
  • Rockets;
    • Difficulty in storing liquid propellant;
    • Very wide operating envelope including orbital velocities, but not very efficient at low speeds;
    • Throttling not possible in solid motors.
  • Ramjet – Uses the forward motion of the engine to compress incoming air before combustion at subsonic speeds;
    • Very inefficient below Mach 1. Requires assistance to reach starting speed;
    • Best operation between Mach 2 and Mach 4. Inefficient outside of these limits unless optimised for a very specific combination of speed and altitude;
    • Very inefficient beyond Mach 6 due to shock-wave effects in the combustion chamber;
    • Widely tested and proven.
  • Scramjet – Uses the forward motion of the engine to compress incoming air before combustion at supersonic speeds;
    • Combustion takes place only at supersonic velocities;
    • Using hydrogen fuel and variable geometry; it can work between Mach 4 and Mach 15+;
    • Inefficient at orbital speeds. Imposes altitude constraints;
    • Largely untested – many developmental challenges remain

Guidance

• High speed effects limit guidance options:
  • Electro-Optical and Radio Frequency seekers unable to operate through plasma generated in front of the missile;
  • Inertial systems inaccurate over long distances;
  • Satellite-corrected guidance vulnerable to jamming / spoofing;
  • Guidance relay on rear section liable to jamming.

Aerodynamics

• Efficient aerodynamic lift-to-drag (L/D) configurations for high Mach numbers are not efficient for low Mach numbers. A compromise in efficiency is required;
• Thin structures are required to reduce drag, but they are harder to protect from thermal effects;
• Shock boundary layer heating to extreme temperatures;
  • LM test vehicle reached surface temperature of 2,000°C;
  • Aluminium and titanium are not suitable. Would have to use ceramics.
