That is a Napier Sabre in that Aircraft of 3000hp making this Fury or Tempest light fighter prototype LA610 the fastest of all the Hawker piston engine power fighters. This is when it was fitted with the Griffon, not quite so elegant I would say.[ATTACH=CONFIG]230735[/ATTACH]

Its from a Bristol freighter, I discussed this with the owner and restorer of this engine. The Centaurus has wider diameter cylinder fins as the cylinders mask each other as you will see in this photo and the incoming air is necessarily compressed further to allow it to do the extra cooling. I was talking about the video as well not the subject of the sale

This gross stupidity about the dangers of radiation from instruments demonstrates the disengagement between regulators and imperially proven science, (not consensuses science which is not science at all). When regulations were drawn up to regulate the nuclear power industry they used a graph call the “linear no-threshold graph” as the basis of setting levels of safe radiation. This was not a scientific graph of safe know levels but just a strait line graph from zero to high levels. It was never intended for anything other than as an aid to regulation of the nuclear power industry. This got leaked to the environmental lobby who immediately seized on it as proof that all radiation no matter what the level was bad. That’s the background.

Wind forward to today, everyone who lives in the south west of England, or flies in a modern passenger aircraft or lives above a few thousand feet in altitude (and many many other situations) regularly gets more radiation than if they spent the rest of their lives siting in a spitfire cockpit. And the delicious irony is those who regularly receive higher doses of low level radiation generally have a higher life expectancy. So it is scientifically proven that low dose radiation is necessary for a healthy life. Getting the message out though is an altogether different matter when we are blessed with politian’s with little life education and agenda’s to keep us all ignorant.

Stuart many of those big marine engines that you can remove a rod from are 2 stroke diesels many with a max rpm of about 120. Some large 4 strokes (less than 250 rpm )you can do this to but again the rpm has to be kept very low. I wouldn’t like to remove a rod on any of the large high speed diesels (over 900rpm) If you removed a piston and rod from a merlin it may last only seconds especially if it was the fork rod you removed

Very good effort from John. If the comments about the con-rod are true, and the large amount of oil tends to support this, then the oil pressure would have dropped very quickly preventing him from feathering the prop, which makes the landing even harder. So a double well done. I’m sure they must have anticipated this scenario many times and whilst its not easy or wise sometimes to do real dead stick landings in certain historic aircraft, John was obviously well aware of what he needed to do.

Unless those P&W’s are R3350 Wright Cyclones or at the very least C model R2800 Pratts à la Corsair F4U-4 (can be rare) they would be a bit underpowered for the Tempest I would guess. But I can’t wait 😀

VX927, My last word. Onshore wind is subsidised 2 fold, offshore three fold and solar on homes 4 to 5 fold. That is not sustainable. It does not take very long if you have your eyes open to see “renewable” is a sham, in fact a reverse “robin hood” of robbing from the poor to benefit the rich.

As I say engineering exists in the reality of the real world, some (much) of our science is in the world of make believe. I think that even those without the benefit of my education in science and engineering are moving to the same opinion.

The UK really has sunk to the depths of absurdity when complete nonsense of the type contained in that renewable energy planning paper are need to be presented to get a hanger built. Renewable energy engineering in such as wind, solar and bio fuels is at the polar opposite of reality as compared to what ARCo/HFL have to comply with to do their aero restoration work and have it certified. One is complete make believe, and one is a the pinnacle of modern manufacturing and maintenance methods.
