The projectile velocity determines the maximum possible range of a unit firing at a target. It is also determines how flat or curved the trajectory is for a given range. This is not the same as the range found in the units file. In all cases, the theoretical range is greater than the range allowed for targeting. However, when a unit is moving away it can still be hit beyond the "targeting range." For various reasons, some of you might want to modify velocities to reduce this excess range (which can be quite substantial.)
The RTW projectile calcs seem to adhere to the basic vacuum trajectory model from physics. With that in mind, for same elevation missile unit to target, the following velocities can produce the following maximum ranges at a 45 degree firing angle. I have marked ones currently used by the program in bold for comparison.
Velocity____Max Range
(m/s)______(m)
15_________23
20_________41
25_________64 Used for Pila range of 35, heads range 40
30_________92 Used for Javelins with range of 50
35________125
40________163
45________207
48________235 Used for Arrows with range of 120 or 170
50________255
55________309
60________367 Used for Slingers with range of 80 stone or 120 bullets, plus ballista, onagers
65________431
70________500
80________653
90________827 Scorpions with range of 250
Note: flaming ammo gets the same velocity as non-flaming at the moment (very questionable in the case of arrows.)
