Ya'll Nibbiars An RFP has been issued by the DRDO for the manufacturing of Kaveri Derivative Engine Dry Kaveri K6. The Engine is currently undergoing performance and operability demonstration tests at GTRE, Bengaluru. The HAL, TAS, L & T and Kalyani Defence are in the Race.

What would be the development time frame? (If everything goes as per plan)
Less than a year or a bit more in development, add a year of testing and in 1 year more will be operationalised. Just the landing gear is to be made stronger and lighter with a floating structure mounted.

Hm. That sounds like it'll accelerate to Mach3-4 & than carry on with ramjet... A lot like the scramjet hypersonic testbed, although that one accelerates more probably. But how is it dual speed then? 😕 (Unless it's aeroballistic... where the booster hurtles it through high atmosphere to increase range, you mentioned a problem for ramjet, after which it'll enter atmosphere & ignite its ramjet. THAT rootless make it a proper dual-speed!.. Possible @porky_kicker?)
IMHO, dual speed is a misnomer. But on other hand, it seems apt as it would be powered by two different types of engine.

Fuel Cell based Air Independent Propulsion (AIP) System Crosses Important Milestone of User Specific Tests


Posted On: 09 MAR 2021 2:09PM by PIB Delhi



Defence Research and Development Organisation (DRDO) has achieved an important milestone in the development of Air Independent Propulsion (AIP) System by proving the land-based prototype on 8 March 2021. The plant was operated in endurance mode and max power mode as per the user requirements. The system is being developed by Naval Materials Research Laboratory (NMRL) of DRDO.


AIP has a force multiplier effect on lethality of a diesel electric submarine as it enhances the submerged endurance of the boat, several folds. Fuel cell-based AIP has merits in performance compared to other technologies.


While there are different types of AIP systems being pursued internationally, fuel cell-based AIP of NMRL is unique as the hydrogen is generated onboard.


The technology has been successfully developed with the support of industry partners L&T and Thermax. It has now reached the stage of maturity for fitment into target vessels.


Raksha Mantri Shri Rajnath Singh congratulated DRDO, Indian Navy and Industry for the achievement.


Secretary DDR&D and Chairman DRDO, Dr G Satheesh Reddy appreciated the efforts of the teams involved in the successful development. He called upon the DRDO fraternity to come up with more such advanced technological achievements by putting extraordinary efforts.

I think i could have ended the discussion aesthetics ver functionality forever by simply giving 2 choices to you all, no middle ground choice.

Would you all prefer a aesthetic wife with zero functionality ? :pound:
Or
Would you all prefer a functional wife with zero aesthetics ? :pound:

Zero functionality includes zero sex :hehe:
Both choices are bad.. I would prefer to not marry at all.. and continue to have faith in my own hands✋👌

Excellent news. When this system shall be fitted in Scorpene, It will make the boomer more lethal than it already is. It is one of the best Submarine anywhere and comparable to anything. It will rule the Indian ocean for sure. Chinese submarines with outdated technology of 70 and 80 era are absolutely no match to This one particularly when fitted with Indian AIP.

In the bottom it is visible AD which should be PAD .

PAD was being also used as TGT isn't it ?
May be missile is the same but when used in interceptor mode, It has to be equipped with sophisticated Seeker and data link. A great sophistication is required for interceptor applications.
