There will also be a number of smaller engines there too from various people.
No timetable as of yet but the stream is anticipated to be running from late-morning (GMT). I will update if there becomes a definite plan, but with so many engines there is likely to be something interesting going on when you tune in.
Thanks to Justin for a fantastic two days of fun in the sun!
Guest engines were a Palouste, Williams WR27-1, Saurer GT15, KHD T312 and a rare IHI DynaJet.
Aid is getting together all the footage and will be assembling a video for YouTube so I'll post a link when that's done. We had over 260 stream viewers when I checked at one point, I hope everyone was entertained and kudos to Aid for all his effort with the A/V equipment.
I did take an obligatory selfie with the RB211, it _is_ running at ground idle as you can tell if you look under it at the totally flat grass!
It was Ian Bennett who lost his glasses and then amazingly managed to find them again a short time later in one piece!
He walked into the jet efflux and it just ripped them off his head. At ground idle the efflux is just about possible to walk through... not very good for glasses/ear defenders though!
I was thinking last night and I wonder if this is the first time a Palouste has ever delivered air to an RB211. Aid did try the Williams WR27 as well but it barely managed to get the engine turning.
For starting the thing Justin has two Stad 250 gas turbine air producers, one refused to deliver air without the RPM decaying so we swapped to one Stad and one Palouste (as per the above pic) which worked well. The RB211 consumes about 4 lb/sec of air during the start, its really unbelievable how much air it needs. The Stad EGT was absolutely on the limit when delivering air and I assume the Palouste (being controlled by Aid) was working hard too. The Palouste also had a very distressing habit of surging machine-gun fashion for a couple of seconds when starting air delivery. This is, apparently, reasonably normal and I was the only one who got a bit nervous
How thick is that slab? Wish I was there! I have beer and fuel money!
It's engineered matting over the bare ground. But it locks togther in such a way that the individual tiles can't seperate by themselves. Even when cooked by the Palouste exhaust it just temporarily bucked a bit until cooled with buckets of water...tough stuff!
The engine stand is on castors but it's held by metal struts that connect to anchor points that are sunk into concrete:
I said to Justin he should put a grandstand in the field and charge viewing Funny thing is the very first we ran it last year a group of hikers stopped to ask questions and then declined an offer to see the start, guess some people really don't 'get' it.
