Linear Shaped Charge Performance?

[lemd]

Hi

 

How much would linear shaped charge be against RHA?

 

Thanks

Not exactly sure what you are asking for here but semtex razor linear shaped charges will go through 6 to 40mm of steel plate depending on the size. Interesting semtex brochure here.

Depends on the size of the LSCs. Offhand I can't remember the rough number, but LSCs are significantly worse at penetrating than charges with cylindrical symmetry.

Thanks

 

CaptLuke, it seems commercial LSCs use cheap liner like plastic, so the penetration is low when comparing to copper liner in warheads.

 

Jason, I want to compare Conical and Linear shaped charge but do not know the measurement. Maybe diameter of conical vs width of LSC, or maybe two systems of the same weight. And how worse is LSC?

Cone diameter versus LSC width is the best metric of comparison. I have some data on LSC penetration performance somewhere (using quality metal liners), I'll try to find it for you.

Many thanks Jason

Hmmmm....I thought I had better stuff. The data I have is mostly for low precision, hand-packed LCSs with shallow angles, which isn't a fair comparison to modern, high precision charges conical charges.

 

Jet velocity is much slower though, on the order of 3-4 km/s and it's not coherent because it's missing a dimension of symmetry. So penetration has to be significantly worse.

It might be fair to compare them to conventional EFP.

Huge coherence and mass discrepancy though.
