Re: Fund Raising for the Bluebird Project

I would echo Neil's comments and encourage supporters to make regular contributions if they can. For the last year or so I've been making a monthly donation but via the Paypal route which is both inefficient in that charges are (presumably?) incurred on every transaction and potentially unreliable d...

Re: Antiques Roadshow/Cockpit Discussion

Remember, Donald wanted to be a fighter pilot, but couldn't due to having had scarlet fevor, maybe he just found something approaching the same risk element.

...K7 than takes off with no disturbance to the water beneath her transom... The silver planing shoes are visible on the underside of the sponsons and the main hull. In the last image K7 has looped the loop and is head back towards the lake surface... Another point of note, is that at no stage in t...

Re: The Last run....

Regarding the roostertail question, I was struck by the regular wake pattern in the picture of the Beryl-engined K7 at Lake Bonney, Australia in 1964: Go to the following link and scroll down to the "Australia 1964" section- http://www.bluebirdteamracing.net/bluebirdsupportersclub/boa/k7....

Re: The Last run....

Although I haven't looked recently at my video's of K7 prior to the final 66/67 converted version, I don't think I can recall seeing the 'rooster-tail' effect in the earlier versions up to '64 -- has anybody? It is intriguing that Steve refer's to KN comments about it occurring in the 300mph+ region...

Re: The Last run....

There is a phenomenon in the last two runs which doesn't appear to generate much in the literature and which I find intriguing. K7's spray plume is modulated to such an extent that a so-called 'rooster-tail' is produced, see: http://www.youtube.com/watch#!v=fL3Vi6iyHOU&feature=related I am curre...

Re: Quicksilver

------Design the front sponson attachments/fairings with a subtle aerofoil shape and just a little negative incidence, so that at low speeds they generate a very small amount of downforce. As the downforce will increase according to the square of the speed, this should not stop the boat coming up o...

Re: Quicksilver

Back to technical matters relating to Quicksilver ... I didn't get chance to address a point made by Keith Mitchell about tailplanes - specifically, the need for a tailplane (to have or not to have) on a speed-record boat or car. I don't want to challenge any of the designers who have equipped thei...
