Design Process

Mohamed,

-Yes smaller would be a benefit, But if i were you i would use the 13" wheels your team have to save money.

-Some of the benefits for running single cylinder engines are, less weight, better weight distribution, simple intake design, simple exhaust(only a bent stainless steel pipe which you can make it yourself at the team workshop).

-It won't be very high unsprung mass, For example Kettering University 2015 uprights were fabricated from 4130 0.025" sheet and was 0.590 kg front and 0.545 kg rear. you can still make light and stiffer design out of sheet metals if you do it the right way, and In Egypt you will save TIME!

-I won't bother design side pods, for the radiators actually i would buy a good quality motorbike radiator, big enough, mount it at the rear of the car or maybe at the main hoop bracing and use a big fan, For the rotor you may need air if your brakes and wheel-package are very small, but with good brake design i think you can finish the endurance without any problems.

Hi Rizk,
Do you suggest a good single cylinder engine that have suppliers in Egypt?

Mohamed,

You just don't understand what Z is trying to tell you! Take another look at the cartoon.

Meanwhile, get an engine...any engine that fits the rules. Otherwise you will still be looking for the 'perfect' engine when the competition arrives.

Hello Mr Clarke,
Thanks for your response.

I took another look to the cartoon, I got what Mr Z is trying to figure out.
But, I'm Still confused how to start it all and to have the whole team working in harmony through the design different phases.

Thanks.

Mohamed,

Just to be clear, the Tree-Swing starts out unnecessarily complicated at its very first stage. Does it really need the three seats shown in top-left sketch?

And from there things just get worse ... until finally you get to the bottom-centre sketch!


~o0o~

Getting back to your FS design, you have already indicated that you are considering a monocoque, "bellcranks" are in the suspension design, you have mentioned the biggest, most powerful engine you can think of, and that it needs a "good" intake system, and wiring harness, and so on.

Are all these things absolutely necessary to carry a single person a distance of 30 km, at an average speed of 50 kph?

Now think about how simple the bottom-right Tree-Swing sketch is, and how much fun you can have on such a swing.

Next try to think of the simplest possible FS car that you could design and build (... to carry one person 30 km at average speed of 50 kph), and how much fun you could have with it.

Here is the Aston University Build Thread 2015. This is a long thread, but just reading the first few pages will give you some good advice on "starting the design process".

(It is quite sad that the Aston-U-2015 campaign ended as it did. Christian and some of the other members of that Team seemed to be making good progress, until (apparently) their Supervisor scuttled their plans and made them go back to doing what they had always done. Namely, building a complete failure of a car. See FSUK-2015 results, with Aston getting zero dynamic points!)
