There is an update from the 'Longbow' jet boat team. In excess of 6500 words it says on FB :roll: Much is interesting. It mentions BBP and David Tremayne - DUO STAY GOLD. https://www.jet-hydroplane.uk/

Interesting information given on the site. The engine info leaves a few questions though! Turmanski R13's [9,000lbs thrust] are available at a reasonable cost with a Russian Technician available to help fit them out for a fee. It is possible to fit two vipers together if you have the right information available as it appears it's not as easy as you would think to do it [surge and such like, causing yaw]>There is manual available to do it [I have one sat in my loft given to me by Jack 'the jet' Hutchins] but they are like hens teeth for availability. K8 was supposed to have twin Viper 600 series engines but that idea was dropped for a variety of reasons.

The manual for the twin Viper HS125 is easily available online, if that helps.

The only difference with the twin viper installation is that one engine is equipped with a synchronising valve that's cross-fed from the other one so that both engines automatically run at the same speed. With two close together I'd imagine it would be straightforward enough to manage them manually. It's a simple engine - we know its fuel system inside out having tuned Stay Gold and we rebuilt the reheat while we were about it so we have that nailed too.
We also did an exercise on the possibility of running twin Orph's side by side as we have a workshop full of shiny examples that'll be spare once K7 has been run and feeding a single jetpipe from two gas generators with a reheat is a pretty potent arrangement on paper.

One thing I forgot to mention about the Viper is that it includes a significant amount of magnesium/thorium and its corrosion product is radioactive and dangerous if inhaled. The repair schemes in the manuals detail how to avoid poisoning yourself whilst replacing Helicoils and the like.

I had a look at his Facebollocks page to see if there was any more news and apparently 23 people like the fact that he has terminal cancer.


Dear Bluebird and speed lovers:

It' maybe the time for me to come out of the shadow, I'm a discreet man and that's the reason of my silence on this forum.
It's true that in May of this year I had a bad news regarding my health.
I'm not in a terminal fase with my cancer, after first chemo, reduction of 50% of the lung tumor ( who was a fase 1 tumor ), and metastazid on the liver disapperead.
I feel fine and continued working " slowly " on the SP600 for the first test next year in the spring.

Other clarification, I'm not using the concorde engine ( do not know from where this rumor is coming :-) ) but the Rolls Royce Adour

Since I'm 12 year, I'm a suporter of Donald Campbell and the Bluebird K7, iIts Donad who put me in this UWWSR adventure

Have a nice week, Daniel

Hey, Daniel... great to see you in one piece and still working on the boat. You had us all worried for a moment there. Welcome to the forum.
