Re: Donald Campbell's restored Bluebird in museum home row

To see my contribution to this topic summarily and impolitely dismissed, is very disappointing. I have never - and would never as those who know me would confirm - claim to be '- the world's self-appointed greatest authority...', an assertion which is so very far from the truth and, quite frankly, ...

Re: Triumph to Tragic in one fell swoop.

In anything to do with K7 and particularly 4Jan67, it is best in my view, not to be too 'absolute'. There are lots of things that are still not known or properly understood - although running the actual boat will help, in increasing overall understanding. There is also lots on information and many v...

Re: Triumph to Tragic in one fell swoop.

I'm working from later on- page 157 of the second edition- when he definitely says 'low pressure fuel warning light'. That he may have said 'air pressure' earlier is obviously a mistake on his part as there was no 'air pressure warning light'. Fair enough. It was said in a casual matter of fact way...

Re: Triumph to Tragic in one fell swoop.

During the start of Run 1, DMC comments that Air Pressure Low is on No, he didn't. There is no indication of starting air contents in the cockpit, only the small gauge visible at the side of the engine cover. Donald was commenting on a low pressure fuel indication, something Ted also reported on. O...

Re: Triumph to Tragic in one fell swoop.

Excuse my ignorance but I take it the Orph' had to be shut down for refuelling for obvious safety reasons? Its normal (aircraft) practice to do so, yes - to stop engines - then refuel. You could refuel with the engine on, the risk is probably small - but the consequences are rather severe, to put i...

Re: Triumph to Tragic in one fell swoop.

Many thanks for this stuff Bill and IM. I think it may go a long way to answering why quick turnaround only runs were deployed in 66 / 67. At no stage during those trial runs on the 10th, 12th, 13th and 14th December did K7 stop to refuel. There is only evidence that he came back straight away. My ...

Re: Triumph to Tragic in one fell swoop.

The LP pumps are of the centrifugal, submerged variety from the Gnat, manufactured by SPE and identical to those later used on the Harrier . In the event of a failure they have a door that lifts to ensure that fuel still flows. The Lucas piston pump would have to pull a little, something it's not r...

Re: Donald Campbell's restored Bluebird in museum home row

On the water brake issue, Neil's posting of the rare TTTv footage (DCBTFRA FB page, Jan. 16th 2017) and my subsequent comments regarding the soundtrack, might prove illuminating... This - ? Quote - ''This video is also remarkable in that it's soundtrack is the only one which contains the unique sou...

Re: Triumph to Tragic in one fell swoop.

But the stopped LP Pump would prevent fuel getting through - so the tank it was in would run dry. Which would severely drop the Fuel Flow - and likely cause a Flame out. Nope- the second LP pump was in place on Bute, unplugged and not running for most of the time, and still allows fuel to flow thro...
