ANOTHER Torpedo (photon) speed thread
Chris O'Farrell
The problem with obtaining a 'real' torpedo speed has been having 2 fixed
points which we can time a torpedo's speed between the two points without
having to worry about things like camera angles, visual magnifications
e.t.c.
Now in this, Tuvok fires a torpedo from a planetary surface at ships in
orbit. It takes approx 1 second for it to leave voyager, climb the
atmosphere (out of a gravity well) and hit the orbiting ship. Assuming they
are in a low orbit, just above the atmosphere (which they could not enter)
we can finally get a speed that a torpedo travels. Now if someone could give
me how high a 'low orbit' is considered to be........

What episode is this? I suspect I wont have seen it. The big problem is
likely to be that there is a scene change, much like the Hoth ion cannon
example. In that case all we can safely say is that it travelled the
distance from where it is not visible to the ISD in a second or two, not
that it came from the surface and hit it in that time. Likely this is
the case in this example too unfortunately.

Um Voyager Volume 6.4 I think. hehe NZ is SOO far behind :)

Actualy there is no scene change. It all happens on the bridge, no FX.
Janeway gives the order to fire (Voyager is on the surface) at a ship in low
orbit (just above the atmosphere from previous parts) and the torpedo is
fired and takes 1 second or so before Tuvok calls out a direct hit.
I just need to know how high the atmosphere is up...
PREDATOR
Well LEO satellites orbit between 320 and 800 Km. The atmosphere reaches
up to about 560 Km though. Since it is such a relatively short distance,
it doesnt tell us much. Things like Tuvok taking the time to react to
the display and then call it out also effect it. He also had to check
that it was a direct hit etc.
Chris O'Farrell
Um they were staying just above the atmosphere (as Voyager could enter it
and did to hide, but the others could not). So assume a height of
say...400k. And give a _wide_ margin and say 4 seconds flight time Max.
Torps would then go (from a planets surface to a starship in orbit) at about
100k/s, which looks about right with some of the other examples throughout.

500km in 2.38s. I posted this earlier but no one seemed to care.
The torp was fired from the DF ranges were called out 1000km,
1500km at an interval opf 2.38 seconds timed by a stop watch.
Factoring in that my reflexes are about 0.1s I'll subtract the
38 giving a nice easy number of 250 km/s.

Now if kynes could put this in the FAQ for a est of Photon Torpedo speed....

Why the obsession with every thread where more than two people agree for
more than two posts being instantly dumped in the R&R?

Because it happens once in every 127 days.
