Engine Manufacturing and Nosecone
Over the last few weeks I was working a bit on the engine and finished off the nosecone. Of course, all beside RB10 troubleshooting.
The nosecone was actually not planned to build that early, but some circumstances forced me to build the nosecone now. This circumstances are some kind of a “secret project” which I’ll show you in a few weeks. Target date is first week of April. Wait and see…
Engine: Front wall of the engine block is almost finished. Mounting points to the chassis are all done and looking very stiff. Not much to tell about the engine any more. Apart from the to expect ultra high grade of detail.
The nose is also a huge improvement compared to the RB7 one. The laminate thickness is much more realistic (not that fat as it is at my RB7). However, the nose is very stiff and the nosepins are very rigid. The front wing pylons were also a bit of a weak spot at the RB7. On this nose, I reinforced the pylons with a steel wire each side and provided another tube for picking up the FW mountings. The shape of this nose was highly complex. Especially the bulge under the nosetip and the step were very difficult to get properly done. But everything worked out quite well without any big problems. The nose is probably a bit lower than the original, but at least it’s within the regulations.
Current state of the RS27 engine. I got a bit of heat damage at the lh side of the engine front. It can happen that I leave it like this to show a few signs of wear.
The first attempt to attach the engine to the chassis was highly successful. The stiffness of the assemblage is astonishing. The tech regulations require 6 M10 bolts to fix the engine to the chassis. In my case the engine is fixed by six steel pins.
Nose cone drawing. Loads of regulation lines to start. You can clearly see the bulge under the nosetip which wasn’t there every race. Means, Lotus had at least two nose specifications over 2013. I did not made a lot of research in that direction. As I know that I’ll build the Belgian specification there is no need to know how many different noses they used over the season.
Structural nose part. Here you can see the crashbox and at the left there is the jig to bond in the nosepins.
Bonding process of the nosepins. That’s always one of the most critical points of the build (as the nose should be removable). But everything went quite well to my full staisfaction.
Templates for the black coating of the nose. From left to right: The sides and the lower part are one part (bulge included). Top cover is in the middle. The cutting edge was designed to be covered by the nice gold stripe. The strange looking part on the very right hand side is a front wing pylon.
First attempt to fit the nose.
Here you can see the internals of the pylons. The rear tube is the structural beam, the front tubes are the pick up points for the front wing.
I’m getting better and better doing the paint jobs. The surface of the nose is almost perfect. A few small tweaks to be done, but in general it’s a great finsih.
Nothing to say about this…
