Re: Triumph to Tragic in one fell swoop.

Did he have an Engine Flame Out at just the wrong time - yes - and then lost the very useful downward force on the bows, due to Engine Thrust - yes. What else could he have then done...? Probably nothing. Could that flameout have been caused by a missing clamp screw in the battery connection panel?...

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

It seems to be quite easy to come off the throttle pedal such that it takes HP cock off with it - that caught us a few times and might be an error on our part, or may be something Donald had to live with too. Interesting. Hmmm. That could explain it. From my last proper job, working on engines that...

Re: Triumph to Tragic in one fell swoop.

Two things Mr 'Canopener'. Why are some people so aggressive on Discusion Forum's? There is absolutely no need to be rude, and my reply certainly did not give you cause to be so. The second thing is this. Keith Mitchell and I (Neil Sheppard) did literally hundreds of hours of analysis with the full...

Re: Triumph to Tragic in one fell swoop.

For those who may not know, the Quick Return (without refueling) had been tried & tested, several times, by DMC in K7 - in its final form - before 4Jan67. That being over the Christmas/New Years holidays, when he took K7 out, with just a few people to help him. I have read Neils book - I have just b...

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

Having seen how violent and effective the water brake is by resurrecting it and actually using it at speed I'd say there's little doubt that had Donald been able to fire it down as his 4th Jan event developed it would have slammed the nose back down, likely destroyed the main spar fairings and blas...

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

Briefly (re)reading the last chapter (10) of Neil Sheppards book, on K7 and there is speculation on what effect the Water Brake might have had - if deployed, on the last run, 4th Jan'67. The conclusion was that in the hovering or floating state - its unclear what would have happened. Ken Norris is q...

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

Bill - I know from what I've read that the thrust line from the jet engine produces a turning moment around the centre of gravity which applies a downward pressure on the bows helping to keep her nose down. What effect does the water brake have in this context? Believe the Water Brake also generate...

Re: New Members

To hopefully avoid the Ducking Stool or the Stocks... :o Not new, vintage 1958. Heard about The Crash on 4th January 1967, on the Radio. Almost immediately built a version of K7 out of Meccano, as boys did then. Bit later found the book With Campbell At Coniston, in the local library. Read it, cover...

Re: Coniston - Spiritual Home?

Ullswater - still under the LDNPA surely - so similar probs to 'C'. Are there any speed restrictions already in place, do we know....? Believe DMC ultimately didn't like it because of its shape, with a dog leg - but not such a prob if not intending to run really fast. Dumbleyung - perhaps a tad far....
