ZIL Screws You: Russian Heavy-Duty Transport Vehicles

AI Thread Summary
The discussion focuses on the unique design of Russian heavy-duty transport vehicles, particularly the ZIL, which features a screw mechanism for movement. Users express curiosity about the drawbacks of this system, noting issues like lateral sliding and performance on hard surfaces. A comparison is made with a canceled U.S. program that faced maintenance challenges and potential problems on slopes. The ability of these vehicles to drive sideways is highlighted as a notable feature. Overall, the conversation emphasizes the innovative yet problematic aspects of this transport technology.

That is pretty cool. I have never seen that. I wonder just how many drawbacks there were to that system. The video showed that lateral sliding could definitely be an issue. Probably not so good on hard surfaces either. Still. It was pretty neat.

In what way? If you mean that it can happen, that's a feature! Or did you mean slip on hilllsides?

The short segment that I saw about the US program indicated that it was canceled due to maintenance issues.

Hillsides. It looked in one segment there that a cross slope could prove to be a problem. Then again, like you said, perhaps they wanted it to do that. It looked to me like it slipped down the slope suddenly.

In the clip that I saw on TV, the one that we made was shown driving sideways as well as forwards and backwards.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
