Work this week was on the wing spar tunnel, which needs to be connected properly to the safety cell and fuselage.
This is done anywhere the two touch. I have done the inside and one wing root so far.
Nothing much to say about this job - pretty straight forward really. Just think about all the curves you have to go round and use several smaller pieces of carbon rather than going for one long strip each side - which would be a nightmare to work with.
The main new thing here was that I was using several layers of Carbon at once. And the weave must be offset by 45 degrees between each piece to give strength in every direction of load. 2 layers on the cell and 3 layers needed on the wing root. Each layer is 10mm less width so there is a smooth transition rather than a huge step.
Next job will be to flip over the fuse and do the other wing root and then the rest of the joins on the inside of the wing roots and the cell.
