Afterburner testing!!! Do NOT turn up the volume..... Loud, very loud
Wow.
What a first week of testing.
Early in the week we had some issues, including fuel leaks, some potentially game stopping electrical gremilns to name a couple & things looked difficult.......
....until Tursday. Something just seamed to click, we wheeled the car out to Golf apron, after 3 attempts (due to the engine being full of inhibitor) the engine settled to a stable idle & we had full control. Job done for the day.
Friday, well, we had plans to see where the distortion limit of the engine was, so we can work out what speed the car needed to be at before full reheat was available.
On the first test we hit min reheat, which was a surprise as with the info we'd had we were lead to believe any reheat would be very, very unlikely.
The second test was something else, we achieved 100% reheat, supposedly not possible with our inlet size, but the engine thought otherwise.
Big tick in the box as this changes the acceleration profile considerably, meaning full reheat from stationary, resulting in a shorter acceleration distance, so we reach Vmax sooner, and that leaves us more stopping distance. BRILLIANT.

Great news. What a first week of testing.

As a Sootie. I'm interested to know how you are measuring "full reheat".

Bloodhound supersonic car fires up Eurofighter engine
http://www.bbc.co.uk/news/science-environment-4144...
The Bloodhound supersonic car has been fired up for the first time - and worked a treat.
Engineers turned over the vehicle's Eurofighter jet engine in a "tie-down" test at Cornwall's Newquay airfield on Friday.
It worked flawlessly, sending a big orange flame out of the rear nozzle........................continues
Bloody fantastic guys. Keep up the good work.
MADE IN GT BRITAIN !!!!!

It's about time some very benevolent organisation or business stepped in now, and funded an attempt next year on the speed record run. Mr Dyson, Mr. Branson, Mr Ecclestone, are you listening? Why is the country so backward in promoting itself. I can think of many other countries, where, once the team had got this far, would be inundated with support.

Dyson must have empty pockets if he's spending on making his own EV. But I am surprised Branson hasn't thrown his hat in the ring. I presume, outside of Dyson, no one with deep pockets is really into engineering and so aren't bothered. Shame.
