The floor on LMP cars doesn't feature a step like in F1, and we don't have this feature either at the moment. Ground clearance, as in 2014 and 13, won't be something open to modification, it will be a fixed value.CAEdevice wrote:About the floor, I was thinking about these features:
[*] Flat between the axles
[*] Longer diffuser than F1 (starting 300-400mm forward the rear wheels axle, with a similar heigth - 120-160mm at the end)
[*] Inclined surfaces to the side edges (the same as LMP1) and a central step (or a minimum distance from the ground of 40-50mm)
[*] Possibility to include rounds on the edges as possible in F1 (R=50mm or even 100mm)
[*] Frontal area (forward the front wheels or forward and around them) where "cuts" like this ( http://www.mulsannescorner.com/PerrinnLMP1-04.jpg ) and inclined surface are allowed
[*] Possibility to "cut" the floor if there is no bodyworks above (= if we look at the car from anove only the upper surface of the floor could be seen
I'd encourage you to have a good look at the rulebook when we release the draft, hopefully most F1-related concepts should still be applicable.Daliracing wrote:well thats a shame for me if it tayed F1 i would have competed. don't know alot of LMP
All of this is included in the rulebook. Rather than rules on windscreen width, we have a template to represent the minimum volume of the cockpit which bodywork must enclose.MadMatt wrote:Regarding other regulations, if engine and gearbox are provided, it is again good to have a minimum surface for the air intake, as well as the cooling. For sure on a closed cockpit car the flow is more difficult to control towards the openings than it is for the F1 car, but that would prevent people running fully closed (streamlined) bodies.
Regulations on number of elements for the wings, chord length, location of the wing compared to wheel axles would be good addition as well, unless this is some kind of unlimited category (I don't mind but I think people not having too much free time would be happy to already have sort of boxes where to locate their wing).
Minimum cockpit/windscreen width is a good addition as well, besides the obvious overall length, width, wheelbase, wheel dimensions, minimum ride height, front and rear overhang.
Including some input from center of mass in the laptime calculation based on the position of heat exchangers is a possibility, but probably less than 50/50 chance of going ahead with this.CAEdevice wrote:What about the Center of Mass? It will be imposed or computed?
I think that it would be quite easy to estimate with a CAD package the COM of the provided parts. It would be interested for the partecpiants to have the possibility to choose the position of that components (es. heat exchangers) in order to influence the COM position. To avoid the need of too many verifications and to compute the COM only once, the mechanics components positions should be maintained as provided, or changed and approved only before the first race.
Maybe someone would try a front engine "roadster" LMP, after falling in love with the Panoz LMP-1 Roadster-S
Internal flows: during the last season, I've made some esperiments with the internal flows of the sidepods.
A simple way to consider the internal flows (not very accurate, but interesting because it encourage some "realistic" solutions) was to design a simple sweep between inlets and outlets, with a restricted section and normal (not rounded) connections in order to cause an energy loss.
I'll have a think about it, but I would expect that we won't be allowing front-engined cars - this introduces a whole set of extra challenges in allowing free positioning of the cockpit templates.
For heat exchangers, there won't be any simulation of internal flows. Any change here, if there is any, will be in CFD on the KVRC side.
I believe Julien is keen to do away with the entry fee, but I don't think this is fully decided yet. Difficult to tell how many participants we will get, but we are making some efforts to attract new entrants from outside F1technical too.CAEdevice wrote:Last questions for today
How many partecipants do you estimate there will be? If a fee will be required (I hope so), it would be possibile to register two different cars paying a double fee?
