    Roof Rack "Wind Tunnel": A Naive Idea?

    I've not yet seen any reference to this, and it would seem so obvious that there must be something wrong with it. However, it occurred to me that a 1/5 scale model affixed to a "ground plane" mounting on the roof of a passenger car tow vehicle, could achieve Reynold's numbers close to 1 X 10E6...

    McLaren MP4-12C with Kinetic/Tenneco/Ohlins CES dampers?

    I've recently seen some photos of the unclothed MP4-12C chassis sporting what seems to be a version of the Tenneco/Kinetic "CES interconnected passive reactive system". They (McLaren) are making a big deal about the absence of ARBs and continuously controlled damping. Sounds like something right...

    Moulton Hydragas and Creuat: coupled hydropneumatic springs

    After Greg Locock mentioned it, I decided to go dig up Alex Moulton's 1979 SAE paper on the Hydragas system. I was startled by the similarites to Creuat's paper of 23 years later (attached), even though the coupled hydropneumatic units are "wired" differently. (In the Creuat, the hydropneumatic...

    Cross linked ARBs ?

    A few (well, 5+) years ago there was a flurry of articles, prees releases, etc. about an integrated hydropneumatic springing system which provided global control of the behavior of all four wheels (you might call it a Global Positioning System) in four modes: bounce, roll, pitch and warp, by a...

    T-BAR VS. U-BAR ARBs

    First, thanks to all who responded to this newbies very first thread last week. Having set aside geometry for awhile, here's my next query. I'm intrigued by the use of T-bar ARB's on some cars (there a beautiful pic of one on the Radical SR9). Nobody seems to talk much about this, but it's...

    ANTI DIVE/SQUAT AS MOTION ABOUT PITCH CENTRE

    First, I'm a newbie here. But, as a teenage lad, I constantly took out Costin and Phipps (first edition! when it was new!)from the library and never quite got over it. As an EE, I tend to look at suspensions in terms of common-mode and differential movements, and my questions may sound at times...
