I'm writing a novel and wanted to research a possible weapon I came up with to make sure the physics are at least possible. However, I could not find anything on vacuum-based projectiles other than ping-pong balls, while this is interesting, but it doesn't answer my question on what would happen on a large scale.
is a vacuum force limited by the medium that is going to rush inside to fill it.
Is it even capable of firing something that weighs more than a ping-pong ball?
How much force can air exert when it enters a vacuum, is volume the most important factor or surface area of the projectile that the air will act upon.
Anyway, with my poor knowledge of physics, I imagined the weapon to be a cone shape (similar to a 747 nose cone), where the projectile is sitting in the curved part, then though matter manipulation (or whatever mechanism you like) the air is removed from the rest of the cone.
The flat part of the cone would be the weakest point in such a shape (I think) and would break first, this would force air behind the projectile and, either shoot the entire cone, or the cone would break and the projectile would shoot forth.
Anyway, that's the idea and the character can make a near perfect vacuum if it helps.
