Well said Retro, and agreed 100%

[Gromit]

I have searched all the card shops, Hallmark, Clintons and the rest, And I could not find one ‘Happy Battle of Britain Day’ card.
What an utter disgrace, I blame the EUSSR.

Your flippancy with regard to young men who fought for their lives in order that you are not writing in German now is a disgrace and shame

Breaks my heart what this country has degenerated into. Foul, self seeking political incompetence has expediated the decline. I remember the sixties, I’m backing Britain. Now your frowned upon for flying the Union Jack. Which I fly proudly in my garden. I love this green and pleasant land, just not some of the people in it.

David I would like to think that there are millions who would agree with you,but when it comes to the ballot box to many stay away,I also remember the 60s and I for one are in total agreement with you.

Rolls Royce produced the fabulous Merlin engine, this is the memorial window at their factory.

// I was born in the late 30s yes there has been violence in the 40s ,50s but what I am trying to say is ////........I am possed
da da da da - Batman!
sorry wrong theme tune - cant do damn busters

Now boys and gurlz - do we need a public announcement in order to commemorate something ourselves ?
Clearly an RC talking here - we can pray for the men ( and gels) who gave up their lives for the future generation ( us) whether or not there is a public ceremony

Today is ..... isnt it the day Adler-tag was called off ?
The difficulty is that over a long period, it is not easy to pinpoint "the day" where a battle is won

Let us also remember the Poles who fought bravely for King George ( not Churchill who gave their country to Stalin in 1945) - they had a higher kill rate than the home grown lads

( I dont think there was a free french squadron - they could have flown their aircraft to Britain on the fall of France - but didnt)

so there !
we can commemorate comething without the need for John McD or Corbo agreeing - they died for us !

// I remember the sixties, I’m backing Britain. //
oh god read the history books
it didnt work - I am backing britain
something about - working for nothing doesnt increase productivity
( well it should! well it doesnt!)
Donald Ross' ht transplant team were handed out union jacks by the photo-hacks and then made to wave them for a photo-opportunity after Britains fist heart transplant

Donald Ross later commented "everyone makes bad decisions" cringeworthy

Back to the Merlin
warning technical comment coming up( rating: v v diff)

The merlin was air-cooled and Paravicini (*) later of hover craft er fame re-designed the cooling system. so that it gave negative drag.
Yeah extra forward foo!
how he do dat den?
well if you hang a radiator out of a spitfire window it will cause drag and slow it up but.....
enclose it in a cowl and put air in the front and let the warmed air out the back and it ..... recreates a jet effect and give a forward force
to the machine = negative drag. 15% - decisive apparently
So Paravicini(**) reinvented the jet effect - something called parallel thingey by engineers

anyone confused by this should see my entry on engineering thermodynamics

(*) foo hoo he den - he brit or what?
(**) there is a wine called Paravicini isnt there - answer yes and also a cardinal in the 1700s

[anotheoldgit]

Anyone understand what all that was about?

[Zacs-Master]

Bits of it. Tiny bits.

[Peter Pedant]

Ah yes AOG
think back
there was this big battle in oo long long ago
1940
and people hav almost forgotten
as it was such a long long time ago

but it was very very important

you're over 80 AOG so I would have thought you might have heard at skool or somewhere ( overhead ) but never mind
it was all so long ago - go back to sleep now - - sleep - sleep

More tomorrow

[Zacs-Master]

Can’t wait!

A further little gem of technical British engineering and technical know how.
The early Spitfires with carburettor Merlins would cut out when the aircraft was inverted which was bad news when in a dogfight with a fuel injected ME 109 which maintained fuel flow at all times to the cylinders.
A female techie overcame this problem with the spitfire by the simple expedient of inserting a penny size disc in the carburettor to overcome.I forget the females name but the modification was known as ????? Penny which was a naughty risque thing to say. Penny being described as something of female parts on the day and no doubt today.

I'm only 7 miles from Duxford airfield ,the home base of the 'Battle of Britain' flight. I expect to see them over my house soon.

thank you retro....

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
It was not until 1941 that Miss Tilly Shilling, with a clever little washer type device, helped considerably but not totally solved, the fuel and float level rapidly raising and dropping in the float chamber that caused the engine cut problem.

Interesting fact 46b:
The Messerschmitt me109 prototype flew with a British-made Rolls-Royce Kestrel engine.
