When the three TLs have the same impedance they look like a single line. Although you can plot V(left) and V(right), there can be no...

The network is drawn across the top. The TDR plot is down the LHS, showing how multiple transmissions and reflections sum.

Welcome to PF. You drill it, in the same way you would drill a hole in the Antarctic icecap.

No. That is the acceleration of the mass density.

Space technology is as good for the US economy as was arms manufacture. The USA has previously primed and driven its economic pump with...

But they are not an integral part of the barrel. We do not talk about silencers here in Tasmania, as they are illegal. We only have...

I think I should answer your questions backwards. LTspice models the specified circuit parameters against time. It does not model...

I see no way to machine a convergent-divergent nozzle with a bend in the middle, or fed directly from drilled barrel ports. So employ a...

@yefj Just write @Baluncore and I will be notified that you have addressed me in the post. ρ = 2 * ( v / Vin ) - 1 ; Where Vin is the...

It is not that simple. It is ρ math, in reflection coefficient space. Voltage varies from 0 to 1. Reflection coefficient ρ, varies from...

ρ = 0; is a perfect impedance match. Zline = Zo * (1+ρ) / (1-ρ) Zline = 50 * ( 1 + 0 ) / ( 1 - 0) = 50 ohms. vf ≈ 1/√εr ; where εr is...

The example you show in post #1, seems to be an attachment to the muzzle, not a drilled or modified barrel. That makes it possible to...

That type of aerial is usually called a tree. By keeping the soil shaded from the sun, there is less reflected heat from the ground...

I guess by combustion chamber you mean barrel, and the bullet travels from left to right. Your A has a small reflective corner, while...
