SBF 16, 17 & 18 set

[ScotsBrutesFan]

End of Jan and my first design

Based on the former airfield on Thorney island, the site is still used by the MOD and is know these days as Baker Barracks.

Split into three sections and shows uniformly at 15.5m wide

The Short circuit denoted by the pale blue route is 2.620km or 1.64 miles

The international circuit denoted by the red short cut is 4.872km or 3.04 miles

The South Circuit denoted by the beige short cut, can be used as a short circuit with the red short cut as well this is 1.82 km or 1.13 miles

The full South Circuit is 3.04km or 1.9 miles

The Full GP circuit is 6.093km or 3.808 miles

I've been asked a couple,of times about the evolution of some of my multi-layout circuits, well the circuit shown below is an example of how it out, the difference I've remembered to screen grab to show it.

First image shows the original drawing...

In my head I knew it would be an easy split into 2, whether it would be a Short circuit and School circuit or 2 raceable circuits I wasn't sure.
Once I started drawing it, the scale of the back straight (no chicane at this point) suggested 2 racing circuits.


The next stage once I have the original done was to come up with "elegant" short cuts, that would continue the flow of the original parts without necessarily looking like shortcuts. Hopefully I've achieved this.

It was at this point the perimeter idea came to me, firstly the Left hand edge, then the removal of the final chicane, what most might see as the most obvious part across the top was the last section that drew. Looking a the design the option was a very quick left onto the 800m straight, or something to give a slower entry onto the straight.
The chicane was the compromise, In my head I have decided that if you use the left hand perimeter section then you must use the chicane....The reason a lack of run off, due to a land boundary that no amount of fantasy money is going to make the adjacent land owner sell.
For those wanting to use the top section, then they have to use the hairpin which allows for additional run off.

Finally with all this in place, that just left the original and shortened first parts of the lapt to join upto the back straight, with the same rules, of full straight and the hairpin or use the chicane and perimeter section. These variations becoming known as International 1 and 2

I haven't posted much so here is one of the ideas that didn't make it to a finishing point I was happy with.

[ScotsBrutesFan]

Geez haven't posted since April...

Ok here is a design that I initially came up with but it was too long, so I've adapted it into a modern circuit. I was goingto finish it off, but lets get this posted as is.

[ScotsBrutesFan]

Another quick design ... A straightforward Anticlockwise 5km.

[AoB Special Stage]

#4- I'd rather have the classic section than the back straight hairpin and following section.

#5-seems like a few of the kinks are a little superfluous

[ScotsBrutesFan]

Just a few days of August remaining for this design.

August Top view.jpg

The shortened version is a proposal that has been suggested as 3.5 miles is a bit long for many local and national series.
For reference the shorter version would be 3.794km or 2.37 miles

Oh I did have a reason for the Mugello kinked front straight but I never wrote it down and can't remember. And if I had more time I'd have added a few grandstands as well.

Some more angles below.

[SKG]

SBF, my favourite aspects of your designs is the slightly sketchy pit entries!

Another nice design

[ScotsBrutesFan]

I'm curious .what do you mean by slightly sketchy....Unsafe?

[SKG]

Maybe slightly. When I do pit entries, I try to avoid making them curve away from the racing surface, I prefer a single kink away from the track and then a straight section. Also, in general I try not to put any sort of pit lane divider / barrier between the track and the pit lane until the pit lane needs to turn.

The reason for both of these guidelines* is I try to imagine a car trying to enter the pits on slicks on a wet track, and aquaplaning off at pit entry. In some of your more recent designs, the pit lane divider + the curved nature of the pit entries could lead to "tricky situations".

Maybe I'm reading too much into it though!

*There are probably many opportunities where I have broken one or both of my own rules

[ScotsBrutesFan]

I'll just keep this thread going into 2017 as I didn't do much last year

Running clockwise at a smudge over 5km (3.12 miles)

25 Feb 17.jpg

[ScotsBrutesFan]

Here is another quick design. I've changed computers , I'm now using a Mac with I don't feel is as accurate so there will be less detail until I can find a way to improve things.

Anyway the circuit is clockwise, the short circuit is just on 1.5 miles 2.4km, the perimeter circuit is just under 2 miles 3.15 km with the full circuit at 3.1 miles just under 5km.

[ScotsBrutesFan]

This multi layout circuit runs from a single pit and paddock complex. It is anti-clockwise


The shortest version shown in white is 2.935km 1.83 miles
10 Apr 17 short.jpg

The longest (twisty) version in Blue is 5.687km 3.55 miles
10 Apr 17 long.jpg

The Car GP is 5.654km 3.55 miles shown in Purple
10 Apr 17 car GP.jpg

The Bike GP is 5.359km 3.35 is in Orange - there is an option to shorten the straight issuing the chicane onto the curve off the straight the difference is about 30m
10 Apr 17 Bike GP.jpg

There are several variations on the Green International layout for cars and bikes they all measure approx 2.5-2.7 miles

[AoB Special Stage]

What was the rationale of having the final chicane instead of having the previous corner integrated directly onto the front straight?

I also have qualms about T3 on lap 1, maybe have initial starts on the back straight?

[ScotsBrutesFan]

When originally drawn, the chicane was part of it as a final overtaking point on a circuit that really only had the hairpin and the 90 left off the top as clear cut over taking points. The Aragon like curve cutting off the hairpin and the chicane were add ons. But I realised that the dead stop chicane wouldn't work for bikes, hence the more open final sequence.
Although I have referred to car and bike versions there is nothing to stop categories using which ever version they like.

T3 shouldn't be too bad, whilst T1 and T2 are quite open they would filter for the most part to single file. It would take some ballsy driving to stay 2 wide all the way to T3. There will always be a choke point somewhere on lap one, atleast here it's not T1

OK, I'll give you that. I'd still rather lengthen the run into T3 because my brain says overtaking point there, but that's just me.

[ScotsBrutesFan]

Life has been seriously getting in the way of any circuit ideas,

Here's something that I've been adding to at a rate of a few minutes a week !!

The Yellow line indicates how I de the racing line staying well away from the pit exit.

It runs anticlockwise as can be seen from the T1 run off.

Circuit is 4.978km (3.11 miles) long and 19m wide

[kerb]

yay, finally someone else's content.

I like it

[SKG]

Ooooh, racing lines for the whole circuit, please! (I know how tricky they are to get right..)

I have precisely seven designs which I've been working on over the past year (to this day in fact, I checked the date on the folder) which I haven't got around to sharing yet #soon.

[AoB Special Stage]

I'm just too lazy to start scanning things again

[ScotsBrutesFan]

Probably the most detailed and complete design I've done in a couple of years

[AoB Special Stage]

I have trepidation regarding 5-6-7 about the decel. I have a personal distaste for the Albert Park style 9-10 section, but that's just me. I'm also not sure how I feel about the pit in because there are a few criss-crossing racing lines at that point

[ScotsBrutesFan]

Here's another from me.

6 Nov 17.jpg

There would be a a Tunnels between T1 and T2 with a bridge between T12 and T13 to access the race school paddock. There would also be either a bridge or a tunnel between T15 and T16.

4.80 km 3.00 miles Anticlockwise. In a modern style

[Purist]

Even though you say it's in the modern style, this one seems relatively simpler compared to a number of your others. I rather like that this one doesn't have as many extra bits sticking out there. The overall shape seems good, too.
