According to Mr Peri of Hindu, Qrsam is ready for user trials and will be in series production by next year.

https://www.thehindu.com/news/natio...production-next-year/article33260806.ece/amp/

Some important points.

1. Developmental trials are complete. The missile will now undergo user trials and they plan to complete user trials within six months and start production by the second half of next year.

2. DAC has already accorded conditional approval . Meaning IA will soon place firm orders or rather place an indent with BEL .Talk about speed with which things are now moving . No more endless series of trials and then more trials.

3. Chapter4 of new DAPP mandates that user trials of systems developed by the production agency must be completed within six months. Wow. Just awesome .

4. This Qrsam missile is the very first Indian missile to feature a laser proximity fuse. IRDE developed the fuse within two years. DRDO boss personally oversaw the program.

5. The Qrsam program has attained 90 p indigenous level. IC boards, photo detectors and electro optics of the ELOP assembly LRU are still being imported . We plan to increase the indigenous level to 99 percent soon.

What D Peri has said incorrectly is that it's a beam riding missile . It's unjammable .He has confused it with the laser proximity fuse . The Qrsam is an active RF seeker guided missile. Backed up by electro optics but then the missile is guided from the BMFR vehicle using a two way datalink for some distance before the round goes pitbull.

Qrsam isn't a beam rider like the Ataka Atgm .
anything on akash NG.

Is it having rocket propelled stage.
No , but they working on propelled warheads which can punch through granite of mountains .

It is a very difficult technology to master , metallurgy needs to be top of the line eg self sharpening , deformation resisting metals needs to be researched first.

So it can be installed on any Bomb and tactical missile btw what happened to that wind tunnel model with lattice fins.

Directionally solidified blades for HPT blades vanes and ,LPT blades

Directional solidification can be best achieved by providing chills . It results in uniform grain structure which in turn improves core strength, Young's modulus, creep resistance and fatigue strength besides the usual increase in tensile strength.

Single crystal turbinw blades and vanes are extensively used in AL-31FP . Koraput has mastered the complete process . We are able to make AL-31 from raw material stage for a couple of years now. The TVC and some exotic alloys are imported from Russia though . Along with some castings and forgings which we further subject to machining to derive the final shape and dimensions .

Turbine blades are usually produced through investment casting process using Ni based super alloys for Hot turbine blades and vanes.

Ceramic cores are used for the intricate finely detailed cooling channels through which relatively cooler air from the LPC is channelled to keep the turbine core and edge temp within acceptable levels and retain structural integrity and fatigue strength not to mention tensile strength. If there is a reduction in strength, the blade would just fly off and hit the casing due to the massive centrifu forces involved .

Trying to use a gun scope which has a narrow FoV to acquire and aim , that too a fast moving drone is not something easy to do.

AAA imo is the best answer , calibre choice will depend on the drone types. Even they will struggle without EO / radar input.

There are WW2 videos on AAA operations , see them to understand the complexity.
I have seen seen ww2 flak gun system. It could be effective against swarm drone. Basically it's debris in the sky.
