Extreme Tetris

Wednesday, August 26th, 2009

The Hopkinson lab was half-drowned in bubblewrap last week as the team put in a gargantuan effort to pack like they had never packed before. No cramming of coathangers into a plastic bag or unfolded clothes piled haphazardly into a rucksack – no, this was the real deal.

A Day in the Sun

Wednesday, August 26th, 2009

Weekends in July and August have been spent on the test track at Ford’s Dunton Technical Centre, developing Endeavour into a solar car that not only looks great, but also performs on the road. As well as using the track, we were given the opportunity to test Endeavour in Ford’s Environmental Testing Laboratory, one of only two such facilities in Europe. The car was subjected to 45degC temperatures, Australian sunshine and wind, with both car and driver surviving the test.

The summer’s testing culminated in a press day on Saturday 15th August, where Endeavour was demonstrated to supporters and journalists, including The Sun and Positive TV (see video, below). Endeavour can be spotted on a double page spread in the Sun Motoring section (Friday 21st June).

On Sunday 16th we were delighted to hit a top speed of 54mph, giving us fresh confidence for the Global Green Challenge.

A full press release and photos can be found on our press page.

Last Sunday I was once again at the Ford Test track in Dunton (Essex) (See Poetry in (slow) Motion for the original testing entry).  This time things were going pretty well when I got there, and the radio link, which I spoke of in the last post, was in fact working (the electrical team don’t lie*)!

Adventures in Expanding Foam

Sunday, August 16th, 2009

This week, the issue of driver comfort has finally been forcibly pushed come to the fore of our minds. Thus far, we have had to prioritize survival over comfort – but now that the many cycles of testing and fixing are almost over (at least, in Cambridge), the majority of the mortality issues have been dealt with, and we can get on with keeping our drivers happy as well as alive.

The Saga of The Upper Shell – now in a Picture Book!

Thursday, August 13th, 2009

Following the (I hope) immense popularity of the tale of the upper shell construction, Team Keen Photographer Martin has kindly developed his own picture story of the event. Quite behind the times, it nevertheless offers a fascinating glimpse into the world of composite-bodging…

Poetry in (slow) motion

Thursday, August 13th, 2009

Last week Endeavour was tested again at Ford’s test track at Dunton (Essex).  The day started off with a bit of slow driving by me – very slow to start with, in fact, since it was the first time I’d ever driven a solar car! I can tell you that I was very excited! And, despite my earlier reservations, the seating position was not all that uncomfortable – though I wasn’t in for four hours, and it wasn’t forty degree heat. Still, it was great fun.

Chao and Julian slowly realised that they had chosen the wrong victim to carjack...

Airy Fairings

Wednesday, August 12th, 2009

The front fairing has just been fitted permanently to the shell.  This means that, instead of the previous solution of bolting the two pieces of carbon fibre together at discrete locations (which are then under more stress), the whole lip has been glued together using a two-part epoxy glue, and then an additional layer of carbon fibre has been resined around the outside of the join to provide strength.  As with all composites work this has to be followed by lots of filling and sanding, our favourite part of building the car….

Also on the composites front, hatches have been cut in the front and rear fairings to allow access to the wheels and suspension parts without removing the whole shell.  This should allow us to easily check the car over, and, for instance, change the tyres in the event of a flat.

Inside Nature's Geeks: the Electrical Engineer

Tuesday, August 11th, 2009
Time to Zero Hour: 2 weeks

Panic Level: 100-125 bpm

This week, CUER SunSpot takes you on a rather dull extremely fascinating journey inside the world of electrical and information engineering - a world where phases, magnetic fields, currents, voltages and, ultimately, sharp corners* cause a multitude of things to go nastily wrong. Or, alternatively, wonderfully right. But, this being problem-solving week, the probability that there is going to be a blog post about everything working absolutely fine is somewhere down there with you getting to see that live Michael Jackson concert next month…

The Saga of the Upper Shell – Conclusion

The Taming of the Mould

Conclusion

Part 1

Part 2

Part 3

After much time had passed, the first layer was complete. Some extra carbon fibre strips were laid around the boundary. Much painting of corrosive, toxic resin was involved and, since, Lucy’s favourite stripy jester trousers had been bleached by the foul stuff, she took no chances and fully suited up in one of those protective things. Despite this, she still managed to get epoxy up her nose. This was not pleasant. Some unplanned extra composite material was also made when Lucy’s hair dipped in the resin by accident. After everything was laid up and resined, release film, felt and finally a vacuum bag were placed on top of the mould which fully sealed it. After some false starts with the vacuum cleaner and then the pump, most of the air was removed and a good 30 minutes spent listening for and plugging leaks. By 1am our heroes had almost reached the end of their task, at which point Kento, overzealous in his electrical safety of turning everything off, unplugged the pump which steadfastly refused to start until Rob did something magical. But Rob had almost run out of magic.

Tyre Change Training at Wheel Fit

Friday, July 17th, 2009

"...see, if you make them round, they work a whole lot better..."

"...see, if you make them round, they work a whole lot better..."

Solar car wheels tend to be very light and will be very delicate. Getting tyres on and off is therefore a delicate operation. We have had help from Gary at Wheel Fit near Waterbeach (15mins drive away), and we went to get some instructions on how to do it ourselves…
