Race Track Doodle 2

Unlike the previous blog post, there are no planned undulations in this circuit. I had a blank sheet of 5mm square paper in front of me. I closed my eyes and came up with the basis of the short circuit option seen here. I completed the circuit with a slight adjustment in places and drew the pits and pit lane in red. But it looked like it was a little bit too short for a grand Prix race track because, if it was to scale (which it isn't) it would take less than a minute to do a lap. So I closed my eyes again and had the basis of the whole circuit and drew that with slight modifications to blend in with the original short layout. The lap is driven in an anti-clockwise direction, as you can see from the direction of the little chequered flag and the position of the grid markings in relation to the pits. There are forty grid markings and so space for forty pit garages. This means that the grid is almost twice as long as would be needed for formula one. I estimate that if this was to scale the main straight would be approximately nine hundred meters long.
The section after turn one would be very fast until turn four. Maybe turn two would be taken a couple of gears back from top because you wouldn't be quite up to speed accelerating away from turn one. A formula one car should have the speed to generate plenty down force to take turn three in top gear. Then there's a chicane and a square right before the circuit splits between the long and short lap options. There's a tight left on to the back straight, a high speed chicane and then a long left that tightens into a short stretch to the esses before the long right parabolica on to the start/finish straight. I would estimate a qualifying lap in a formula one car would be somewhere in the region of ninety three to ninety five seconds. I estimate the long circuit to be about 5.5km, which is about 3.418 miles. 

Race Track Doodle 1

Bank holiday today so no college. In my spare time I did a couple of race track designs. The first three turns in this were influenced by Sochi formula one circuit in that there is a fast kink right and then a relatively tight right into a long sweeping left. The short circuit option sweeps right to a long straight part of the way round turn three. After the long sweeping left it's up the hill to a long right turn. There is a concave slope in the land from high to low, the start/finish straight being higher than the back straight/sweep. Turn four on to the straight on the left hand side of the circuit is the highest point with turn seven, eight and nine (hairpin, back straight/sweep) the joint lowest points. Before that you have to negotiate a tight right into a long left similar to the classic turn eight in Istanbul Park. Exiting turn nine at the bottom of the circuit (top right hand side of the picture) there are a series of turns that gradually get faster up the concave incline to the main straight. Turn fourteen is the fastest and the long sweeper (fifteen) on to the main straight is slightly slower. About halfway around the final turn is the pit lane entry. Actually, now that I think about it, the final turn reminds me a bit of the parabolica at Estoril where Villeneuve famously got by Schumacher around the outside in '96.
I have a name for one turn already. I reckon cars would try to get a slipstream and attempt to out-break into the hairpin at nine because they'll want to be ahead going into the next series of turns before the start/finish straight because it would be too difficult to overtake and being behind a car would mean a loss of aerodynamic grip due to lack of downforce from disturbed air. So I reckon spectators would see a lot of action approaching turn nine. That is why I named it "Action" corner (or "Action" hairpin if you like).
You can also make out grandstand areas in red and an earth bank for spectators next to the left and right sweepers before the straight. The squares in the paddock area behind the pits are meant to be buildings for the race teams and officials.
