Generic question about hovertanks.
By what mechanism do they negotiate hillsides and going downhill/uphill on paved roads ?
One of those don't ask don't tell subjects ?

Not sure, in the Hammers Slammers books they dig in and power thru, or the power increases to lift the front. Wonder how the LCAC's handle it ??

Love those details, Steve! Especially the rack in back.

Hovercraft, by their nature, are not great at negotiating steps or troughs and they are absolutely unable to climb any but the most gentle of hills. To start, the air cushion acts perpendicular to the surface, not the local gravity vector, so instead of lifting straight up, you actually get both pushed a bit back _and_ the lift vector is now less than the gravity vector, meaning you have to pump more air into the skirt. And then the engines have top provide some thrust up the hill because the weight of the vehicle wants to roll down the hill. And that's to just sit in one spot on a slope. To climb the slope you need additional power to accelerate up the slope. Enough power to actually overcome the mass up the slope angle. Which is a LOT.

Which is why hover craft are not used as combat vehicles today and, frankly, won't be used as combat vehicles in the future, no matter how cool Hammers Slammers are (and they are). Ground effect vehicles really don't work well when the ground isn't mostly flat.

Now, using engines to directly provide hover lift and not relying on ground effect, that would work. essentially you are flying all the time at whatever altitude you like.

But that's a different universe. Like Star Wars.

Agree, no surprises there - Thank You
If that holds true even in BTS universe, it is then necessary to make technology advance to vectorable ground proximity resonance anti-gravity drive to negotiate slopes and irregular terrain. :D
Thatz for sure on a round earth.

Love that hull shape  :-*  And bring on that vectorable anti-gravity drive  :smiley:

E100 sure lends itself well to the hovertank design!

Yes, it sure does. I have used the armor skirts before – although the lines did not turn out as good as this time.





Skirt armor and turret for this one –



And of course the turret on Bruno, the tracks and bogies even went on the Siberian Logging Tractor.
I will pick up the E-100 anytime I find it on sale or at a show.

Well built well painted hovertanks. :smiley:
Be interesting to read analysis reports about tradeoffs regarding composition of skirts.  Material type versus weight versus thickness versus projectile damage versus air pressure loss versus mobility impact.  Am confident you made best engineering choices regarding these concerns.
