Hello everyone, this is my first year so I have developed a very rough model with which to test some ideas. I hope to improve a few things in the next two weeks.
I'm going to send you the car for evalutating the nose respect of the rules, even if the front wing-plates are completely approximate.
I've found quite difficult to comply with the section area (120000mm2 and 50000mm2) fo the side pods.
The nose 2014 rules don't impact deeply on the downforce, on the contrary the absence of the rear beam plate seems to be quite important.
A confirmation: is it right that the lower part of the floor (central part) is about 30-40mm from the ground? I would expect F1 were nearer to the floor.
The sidepods were expected to be bigger this year and we also got some very unrealistic small sidepods last year. So this was sort of voted upon as the best way. With your design it will be harder to hit the regs, so you'll need to find some sort of compromise (after all thats what it's about) maybe make them wider?
the nose rules will give you more front downforce, so the cop will move forward. The challenge is balancing this out and getting more from the rear. As you say, the beam wing and shallower rear wing make this harder. A good diffuser would work wonders
that sounds about right. It would be much lower, its just something carried over from last year. I presume there was a reason why, maybe to do with the cfd or something.
i notice you don't really have any aerofoil shapes going on with your flaps. Those little winglets as well will be giving you drag and not much downforce as they will prob be stalling.
Yes, I actually don't have any idea about wich airfoil design to adopt, so I'm using simplyfied profiles now and I'm planning to run a CFD optimization of the flaps in the next weeks (in the meanwhile I'm studying airfoil theory...)
The biggest problem now is to make the floor work. I'm trying a lot of different diffuser design, but I'm still computing no more than 100kg of downforce generated by the floor and diffuser.
I wouldn't worry too much about the diffuser at the moment. There's no point working on different designs when your not maximizing the flow to it. Try and work getting as much clean air to it as possible then work on your design.
well, maybe for f1 but i think we'd be lucky to achieve that
with some good simple clean wings using some aero shapes you'll make better progress. Look at f1 2009 cars for simple wings. Your getting complex without starting simple so you don't know whats not working.
The performance is still ridiculous (less than 1100N at the speed of 100mph, I really couldn't do better) but for a while or at the end (because of some things I need to resolve at work), this is the car.
