How fast can you go on Duna with a rover ?

[TheGeekno72]

Hi, I'm TheGeekno72, and I'm testing my new rover recently landed on Duna (It's the first time I land with a rover in fact) and I was driving when I'm looking the speed meter : 27.8 m/s = 100 kph !!!So I'm asking to you (like a challenge) how fast can you go with a roveron Duna and give the comparison with Kerbin and Mün (Mün only if you want)

With Duna's gravity, this could give new meaning to the old saw about how "I'm not driving fast, I'm flying low".

This should go in the Challenges subforum.

The only rover I've landed on Duna was a curiosity style thing, not at all built for speed. It was also back in 0.20 or something...

same thing most of my duna rovers and probes have been giant heavy beasts that aren't meant for speed but for either good looks or to carry a but ton of science payload.

but i have gone insanely fast with the kerbal jetpack in the duna atmosphere.

I did > 50m/s on Moho one time going down a mountain... Broke the rover but managed to save the Kerbal from a deadly impact somehow.

How about this piece of engineering art: extremely fast rover "Ghost". Safe speed on Duna - ~70 m/s, almost safe speed on Tylo - ~100 m/s. This device can be dropped from 30m altitude on Kerbin without damages. It was designed in version 0.90 but keep work in current version of KSP except Kerbin, Eve and Laythe (too dense atmosphere for ion engine).

I got this one up to 85 mph on a downslope. Then I rolled it over and it broke apart. The Kerbal survived, but he wasn't going anywhere.

Hey

27m/s+ on level ground seems accuarte. But, on a long downslope you can get much faster. Frightfully fast I would say.

To survive high speeds (ca over 40m/s) you have to get a bit creative. The suspension of the stock wheels can´t cope with the forces when you hit the next bump, and then either the wheels are breaking or the suspension locks up -> Desaster. Additionally, at that speeds you will jump quite a lot.

So you have to design some sort of an additional shock absorber system.

 

 

 

This baby hit 60m/s on Duna once, around 50 on Mün and survived.

This shock absorbers are pretty simple but reliable. Structural pylons connected to the center of the rover -> I beams -> wheels. Stabilized with a few carefully placed struts.

Best rover I´ve ever built so far. Cheers

Craft File Pls.

P.S. whats that in your sig.

I hit 33 m/s last night.

My rover also has a VTOL system and chutes...

It was originally designed as an OMS and retrorocket system to soften the landing, but it has plenty of thrust to VTOL, even on Kerbin (I think it got to 600m high on Kerbin with full fuel).

So, in theory... I could get going really really really fast going down a slope, and if there is uneven terrain ahead... fire rockets and pop chutes....

My rover has plenty of torque from 1x mk1 inline cockpit, and 1x mk1 pod... Setting it to follow prograde as I drive along the surface seemed to help the stability.

This is my science Rover:

It runs with two modes, low speed with electric drive and high speed for cruising and not breaking the wheels, powered by monoprop. Here is highspeed mode:

If you find a flat "track" you could make 100-120m/s I think. The problem is, this thing starts to jump beyond 30-40m/s and sometimes the landing will break the rover.

Airtime with 90 m/s! will be a rough landing, though.
