A low protective curtain which can absorb the energy from a grenade explosion, is diagonally placed in the shelter entrance.
A grenade that rolls under the curtain or has been placed at the entrance, has most of its energy absorbed. Whatever is left of the grenade explosion is directed outward, so
terrorists cannot kill innocent young women hiding inside.

I have... questions. What is the curtain made of? How does the blast not simply rip right through it? How does a grenade that has rolled under the curtain have most of its energy absorbed? What of the shrapnel from the grenade? How is this better than a tried and true door? |
|
| |
Can the innocent young men be protected too? |
|
| |
For test purposes, we couldn't find any. |

Why not just have a door? Even better, a locked door. Grenades aren't magic, they're just a small amount of explosive inside a casing that fragments into shrapnel. Bunkers have been constructed with grenades in mind for many years. The entrance is usually constructed with a couple of corners so that there's no direct line of sight/travel between the interior and the entrance. Ventilation holes are often designed with multiple gratings, in Normandy there are bunkers with fake vent holes that lead straight back outside, so you drop a grenade in and it pops out at your feet. |

They also generally have grenade sumps and sloped floors so grenades that DO make it in roll harmlessly down into the sumps to explode. |

I take it that this curtain has several feet drooping on the ground to trap a grenade that rolls under it, yes? |
|
| |
I would suggest kevlar wrapped dilatant pockets to distribute the energy across the entire curtain. |
|
| |
Nothing says "I recognize the danger you represent" so highly as having a grenade lobbed at you. Embrace the recognition! |

Ah.
I've been puzzling over this idea and how it was possibly supposed to work. But that would explain it. |

It's a handy store for any bomb delivery service you may subscribe to. |

If the object was to have a more portable, man-carried barrier, I think a minimal amount of Explosive Reactive Armor in the hangings would help. If this looks like an A/C curtain like on walk-in fridge open doorways, and made of many overlapping drops of Kevlar and ERA, you might have a chance of foiling the shrapnel. |

More simply, if we are talking about dugouts in trenches or bombed-out building ruins, the simplest solution to grenades is to not get any thrown at you. So many of these dugouts are a black hole in the landscape to spotter drones, even more so in winter with the snow. Camo, camo, camo. |

My first thought after reading the subtitle was that it was somewhat like a baseball pitching net, but powered so that any object thrown in the door gets ejected with additional force. I still might prefer a normal door, but if you had a door in a deep alcove, one of these in front, it might help a little. |

Low, so no need to close door and people can quickly jump in over it, to get away from the shells. |
