Sorry, I was referring to the many hundreds of Japanese characters surrounding the photos. I assumed there was more to the story in those characters and you had some way of reading them. I have never messed with different languages via windows except some BabelFish fumblings. Yes I saw the photos. No I wasn't clear enough in my response. My 'guess' would be they had the Yen to design the updates. But was that just a scale Aero Model or the actual car? CAD is probably expensive but not nearly as much as full sized wind tunnel parts fabrication. |

It says that they developed it, but now it's cancelled and won't race. |

Good plan, but if I'm President of DAVE MOTORS and I'm funding the project, then it wouldn't take much more than a new decal to change the Dome to a DAVE. (mkIII) They wouldn't need to build an entirely new machine based upon the lessons of the current car. They HAVE the car. They just don't HAVE the funding. dh ps, I'm getting ready to move to Texas so I won't be able to reply for a couple of weeks. I won't be online til early October...if all goes well. ddhh |

Sorry for off topic.
This is a sketch of an electric vehicle by Dome that Mionoru Hayashi designed. (not by Adrian Newey ) http://twitpic.com/2yx911 |

I was thinking it resembled one of the possible designs that indycar considered recently. Specifically the 3rd design listed on this site.

If rent includes support , it might well be a good deal , for the short term . Would that be eligable for the AsLMS next year ?

So lets get some money together then ...
"10/10 Dome S102" sounds good, doesnt it? |

Motor Fan Illustrated magazine featured Dome S102 of the 2010 version(not 2011 ver).
The car was named S102i(Improvement). A detailed update is performed besides a feature rear section. As for the suspension, the hydraulic bump stopper(third element) is used at the front and the Dome's oridinal damper is used at rear. In addition, upright made of titanium was adopted (Only Qualifying is used in S102). The simulation time of S102i is 3:23.593(Sarthe circuit). (Aerodynamics data by Dome) ---------drag(N)---DF(N)--DF/Fr---DF/Re---L/D---CoP S101.5----2580----8770----3541---5229---3.4----40 S102------2358---10060----4575---5485---4.5----48 S102i------2462---10110----4600---5610---4.4----48 |

Thanks, that is always an important data point to include. DF at 220kph is not the same as when measured at 325kph.
What struck me about the numbers was the large jump in downforce from the old S101.5 to the S102....but then...two years of probably intermittent aero doodling provides only ½ of 1% increase in df with the S102i. The cost in time and facility(wind tunnel, CAD etc) use must have been tremendous for such a small step forward. And then for the ACO to continuously make rules changes that both thwart the development and force other items to be included(read that as an UGLY fin) and you have to admire Dome's hobby. Other private Manufacturers like Lola and Zytek and OAK obviously face the same financial roadblocks to development. I wonder what the downforce improvements from the original Lola B05/40 to the current coupe were? Did we see half a percent gains with the open footbox and later the coupe? |

The step in the aerodynamic performance with an improvement of 1 - 1,5 % comparing S102 to S102i is quite very well. The smaller 1,60m rear reduced downforce by about 6-10 % so the overall improvement was 7-11 % and so quite impressive. What is not clear is the unit for the aero figures. Kilograms could not be , Newton meters not and pounds also not. More than 10.000 pounds at 320 kph was the peak of the lastest ground effect Group C cars like the TS010 with an peak L/D of 6,2:1. So this figure at 220 kph is impossible. |

A quick division of Downforce in Newtons by drag in Newtons gives us 10110 ÷ 2462 = 4.11 (S102i) That is somewhat different from their result, but not totally out of the range. oh, and great point about the Aero restrictions. I commented about them but totally forgot to include them in my analysis. That's why I'm a mail man and not an engineer. lol! dh ps.. it may state in the article, but we don't know if this is the max df the car can produce with full attack wing settings and front winglets, or is this the car in Le Mans trim with flat wings and no diveplanes and minimal front splitter size.

10110/2462= 4.106 and not 4.4 likewise, 10060/2358= 4.27:1 and not 4.5:1. The units are Newtons. |

I think the figures are all for a Le Mans version. I have never heard that Dome tested a high downforce version.
The L/D figure is not bad but also not fantastic. The 2003 Bentley Speed 8 was in the same region. Since that the downforce was reduced by the rules, but I had thought that there were more improvements. But comparing wind tunnel data can only give a small intention, cause different wind tunnels, model sizes, and measure methods resulted in different figures. It is really a shame that there is no good technical article about this great car here in Europe or the USA. The RCE article was also not one of the best of this magazine. |
