mender Posted July 19, 2018 Report Share Posted July 19, 2018 (edited) Just watched a program about these tanks and they claimed that they stopped quicker than a car. They implied that it could stop from its top speed of 42 mph in 30 feet. That's about 2 gs on what looks to me like pretty hard rubber blocks. Not buying that. Does anyone have more realistic numbers? Edited July 19, 2018 by mender Quote Link to comment Share on other sites More sharing options...
enginerd Posted July 19, 2018 Report Share Posted July 19, 2018 On what surface? Does it have steel treads that dig in like a bulldozer? Quote Link to comment Share on other sites More sharing options...

Does anyone have more realistic numbers? Hard rubber, but a HUGE contact patch. Escecially if it's soft surface. I know they're know for tearing up soft asphalt.

Black Magic Posted July 19, 2018 Report Share Posted July 19, 2018 Deformable surface vehicle dynamics is it's own world. Better question, how fast can it stop without destroying the surface..... 2 Quote Link to comment Share on other sites More sharing options...

karman1970 Posted July 19, 2018 Report Share Posted July 19, 2018 Found a Motor Trend article that claims .4 Gs braking. Other articles only mention braking capability in relative terms - most of them akin to hitting a brick wall. This video shows it taking a couple tank lengths (1:27 mark). But it looks like he was pumping the brakes to keep from losing it. I'd say if he just locked them up it would take maybe 1.5 hull lengths, just guessing. On dirt I wouldn't be surprised if it was a little less. Quote Link to comment Share on other sites More sharing options...

I'm familiar with dirt sprint cars; wonder what the difference in force is to pull apart asphalt vs a well prepped track ... Quote Link to comment Share on other sites More sharing options...
