Speaking of turret traverse…

I’ve read a few things on the internet saying that the Panther A and G have 36 degrees/second turret traverse with 3000 RPM coming from the engine.

As far as I can tell this value seems way out of line. I’d expect a linear relationship between the engine’s RPM and the turret traverse, and a lot of time the 36 degree/second value is paired up with other values at other RPMs that do follow a linear relationship (for example, ~8 degrees at 1000 RPM, ~16 degrees at 2000 RPM, 20 degrees at 2500 RPM).

As far as I understand how these things work, a linear relationship is what makes most sense. At lower RPMs the engine has more torque (HL 230 achieves peak torque at 2100 RPM, if I remember right), so if there was to be a bigger jump in achieved turret traverse it would be there, but torque/horsepower only really matter for acceleration, not the actually maximum speed, at least when it comes to stuff like velocity of a vehicle for example.

Really I’m more just wondering if the 36 degree/second turret traverse was just pulled out of someone’s behind and people ran with it.

The system simply takes the engines RPM motion and converts that into a traverse gear RPM.
So it directly influenced the traverse speed of the mechanism and the traverse speed is very consistent.
Same how manual traverse is directly linked to how fast you can spin the traverse handwheel.

So if you know that the turret traverses X °/s at 1000 RPM engine speed, it will do 3X at 3000 RPM.

Unlike the Pz IVs electric motor, this should result in instant acceleration due to the great mechanical advantage of the high engine RPM into a relatively low gear ratio for the traverse mechanism.
Like it would taken little effort to rotate the turret by 0.1°/s and with 3000 RPM and a conversions to 250 RPM (8 strokes of the hydraulic motion to rotate a gear ones) you get 25°/s, as an example.

In other words, 36°/s makes no sense given the other values I’ve seen.
