This is all we know. I mean what kind of missile. Is it a ARM as talked about lately, or anything else. Because Rudra M1 and M2 are reportedly different short of ASM.

Just before you claimed DRDO never talkied about it and its a theory!. Not worth discussion if you cant admit it.

I only talked about its role. Look at the post #4531.

There is no doubt that its an ASM, but there is doubt whether its an ARM or anything else. Parliamentary committee also reported it as TD. Nothing more, nothing less.

You should follow things carefully before making assumptions.

Interesting why laser proximity sensor for a ASM that too with a IIR seeker ?

laser must be fuse. IIR seeker means its no hypersonic or high supersonic.

What is a ground mine? @NeXoft007

Ground Mine

The processor-based ground mine (PBGM) is a microprocessor- controlled advanced mine to be laid either by a surface ship or launched from a submarine. It is classified as an intelligent mine as it can assess and quantify the environment and accurately identify and destroy actual targets. The mine is designed to detonate using any one or a combination of the three influences created by a target. Advanced digital signal processing techniques are incorporated in the mine to discriminate between acoustic noise generated by real target and acoustic countermeasure. The mine design also includes advanced digital filtering techniques to extract pressure signature generated by ships and submarines in the presence of high sea ambient. Classical safety features are also provided. The mine is designed for long storage and operating life.

Some more naval mines

1.PBAEM processor based advanced exercise mine

2. PBGM processor based ground mine

3.MIGM multi influence ground mine

4. LWM light weight mine

5. LIMPET MINE

My Guess about Rudra:-

Rudra I is NGARM

Rudra II is NGARM airframe with IR Seeker

Rudra III is NGARM airframe with MMW seeker

Adrushy MK-I anti tank mine

Adrushy MK-II anti tank mine upgrade of Adrushy MK-I

Prachand anti tank mine upgrade of Adrushy MK-II

My Guess about Rudra:-

Rudra I is NGARM

Rudra II is NGARM airframe with IR Seeker

Rudra III is NGARM airframe with MMW seeker

What is the weight of NGARM ?
RUDRA M III reportedly weights 1.6 tonnes

Also RUDRA M II airframe is different from NGARM airframe

 

[porky_kicker]

Efficiency of IR supression systems for naval applications > 90% @ 3-5 micrometre band

What is the weight of NGARM ?
RUDRA M III reportedly weights 1.6 tonnes

140 Kg as reported. Even on that IAF was crying and urging to do some more weight shed.

DRDO CVRDE 700 HP diesel engine under development

The chosen design parameters are

8 cylinder V90 with cross-plane crankshaft with tungsten inserts
Bore x Stroke 114 x 112 mm
3600 rpm,
OHV,
Waste-gated Turbocharger,
Charge Cooler,
CRDI
Dry-sump lubrication
Mean piston speed ~ 13.4 m/s
BMEP ~ 23 bar

For 700 HP engine, DRDO CVRDE is developing

Self Cleaning Air Filtration System (SCAFS) for desert operations

cooling systems and waste gated turbochargers for high altitude operations.

Why is CVRDE developing 700HP engine? Just a few months back, Nirmala Sitharaman had announced indigenisation of 2 engine - 780HP and 1000HP for T72 and T90 respectively.

For FICV etc

As for indigenisation of the T series engines , they did so via TOT nothing ground breaking about that , just too much self praise and much ado about nothing .

Designing from grounds up and then productionizing it and productionizing a imported proved design ( indigenisation ) are 2 different ends of a pole.

Look at the lateral thruster. You would have a fair idea.
