Lotus E21 construction report part 1

Basic Monocoque Drawings

Last night I started with the first basic drawings for the monocoque of my new project, the Lotus E21 of Kimi Räikkönen – btw. my absolute favourite driver. 🙂

A bit work is left at the rear of the monocoque and at the side pods. At the rear I couldn’t reconstruct the correct shape of the cutouts for the cooling lines (water and oil radiator). I hope a few new pics will appear at the GP of Belgium in two weeks where I can spy out the correct shape of this cutout. I’ve already tried to reconstruct the shape of this cutouts at the predecessors E20 and R30 but didn’t find anything helpfull. The correct side pod shape I’ll recalculate when I’m starting with the manufacturing of idems.

The engine drawings I can take over from the RB7. It’s Renault RS27-2011 is quite the same as the E21’s RS27-2013. I’ve to look if I can find some visible changes between this two versions.

Since the start of the season I’ve collected 397Mb data from this car. About 1012 pics, tech. regs with appendix, some publications, tech. analysis and so on. A few additional data I collected from the predecesser E20 in case of the engine/engine mounting. a short comparison to my last F1 built, the Red Bull RB7: There I had 277Mb data et the end of the building process. So we can await a much more detailed model of the Lotus than it was at the RB.

About paulsf1

My name is Paul Bischof. I’m a student in mechanical engineering at the Technical University of Graz in Austria, expected finishing in February 2016. Since I was eight years old, I am building model planes out of paperboard. Since 2004 I scratch (that means building without an assembling set) Formula 1 and sportscars in 1:10th scale. The average time I need for such a car is around 400 to 700 hours within 4 to 8 months. One car has around 3500 up to 5000 single components. On this blog, you can take a look on my work and later, after my studies, hopefully you can see me in Formula 1.
