INTERESTING FACT OF THE DAY
 
During WW2, the Luftwaffe got good quality avation fuel for their fighter aircraft from Romanian oil, typically 130 RON.

The RAF had equally good fuel, about 125 RON.

However American crude oil was of lower quality, and thus the fuel was more like 80 or 90 RON. This led them to develop protective additives like lead to allow more tuning of higher compression engines with superchargers. Eventually they had ratings of around 150 RON.

It was commonly recognised that the Germans had more powerful engines. Why was this? Because they had direct injection systems in their engines and this allowed them to use Nitrous Oxide while dogfighting, increasing power output by 50%.

I didn't know that.


Who's next for an I.F.O.T.D?

(a) More people are kicked to death each year by donkey's than die in airline accidents.

(b) An Albatross can fly for up to a week without flapping its wings.

The opricuity of the ecliptic is 23 degrees, 27 minutes, 8.26 seconds. So there. :?

An hour's rain would do more good in five minutes now than a week's would do in a month at any other time of the year. 8)

90% of people are caused by accidents.

The skin of a hippo is almost bulletproof.

A giraffe has the same number of bones in its neck as a human.

Faster than an SV, a Greyhound is capable of reaching its top speed of 45mph in only three strides.

The Bloodhound is the only animal whose evidence is admissable in a US court.

The Pentagon has twice as many toilets as is necessary because when it was built there were still segregation laws in place required separate facilities for Blacks and Whites.

Besides humans, elephants are the only animal that can stand on thier heads.

The most impossible item to flush in a tiolet is a ping pong ball.

Apart from Elvis, Judy Garland also died on the loo - whilst King George II died after falling off the loo.

A rat can survive longer with out water than a camel. Got that off the back of a Penguin bar.

You don't have to have direct injection to use NOS. Don't need injection at all.

tricky 28-02-06 10:21 PM

When I remove excess nasel with some tweazers, it always hurts more from the right nostril. Don't know whether thats the case for everyone or just me.
A fact never the less.

The uniforms worn by the SS were designed by Hugo Boss.

tricky 28-02-06 10:35 PM

On a military theme then....

Red berets and the "Pegasus" logo of British Airborne Forces was the idea of author Daphne Du Maurier, Who was the wife of Lt Gen Freddy "Boy" Browning

That IS an interesting little snippet.

Like the original VW Beetle was designed for Hitler by Porsche to be the "peoples car".....

Interesting bit about fuels in aircraft.

British pilots did see a marked difference in performance of their aircraft when using the American fuel over the British.

The Germans didn't know this so when they flew captured Hurricanes or Spitfires, they used thier own fuels and had false power readings...they thought our aircraft was slower than they actually were.

Boring, but true.

Nitrous could only be used in short bursts and usually when running!!!German engine development never matched what was needed and so nitro was a cheap fix.

from ww2, britains leading secret agent was a chap called wing commander Yeo Thomas...The White Rabbit.

No. Although I did write a letter to my (then) girlfriend while I was on a tour of duty in the Falklands that we had to go round picking the penguins up again after a plane had gone over. Twas a joke tho'.



An "interesting" point for you:- Alfred Nobel, the instigator of the Nobel Peace Prize, invented Dynamite. :wink:

More VW facts. The chap who designed the Beetle was Dr Ferdinand Porsche, it was his son that started the Porsche (as we know it today) company.

Also, imediately after the war, it was the British Army that organised putting the Beetle back into production.

I didnt think that extra bit was needed. Still cool to know :thumbsup:

Jon Pertwee served as an officer aboard HMS Hood, adn was lucky enough to be on shore leave when she was sunk by the Bismark with only three survivors.

Denholm Elliot served with the RAF and was sot down during a bommbing mssion over Denmark. He saw out the last three years of the war in a POW camp in Silesia.

Murray Walker drove a tank during WWII.

Christopher Lee served as a Flight Lieutenant, as well as with Intelligence and Special Forces in the Western Desert, Malta, Sicily, Italy and Central Europe.

Concorde had a system of baffles on its engines to slow down the air entering the engine to sub sonic speed as the engine wouldnt run properly otherwise

DID.

Such a shame they removed such a great aircrsft.

Actor Richard Todd served with 6 Para (I think) and fought at Pegasus Bridge on D-Day.

Interstingly Richard Todd plays Maj John Howard (who commanded the initial glider assult at Pegasus Bridge and heroically held the bridges afterwards) in the film "The Longest Day".

I am unsure who plays Richard Todd in the film :D

Clark Gable flew with the 8th airforce on bombing missions over Germany.

Lucky to survive that one :shock:

As did Jimmy Stewart, who reached the rank of Colonel and was awarded the Distinguished Flying Cross with Oak Leaf Clusters, the French Croix-de-Guerre and the Air Medal. After the war he remained in the U.S. Air Force Reserve, and reached the rank of Brigadier General.

The penguin is the only bird that walks upright.

Flamingos can only eat with their heads upside down, and pigeons are the only birds that can drink water without having to raise their heads to swallow.

The most poisonous spider isn't the Black Widow - it's the Wingless Daddylonglegs, but it's fangs can't pierce human skin so it poses no threat.

Oh yeah, try this one - apparently no piece of paper can be folded in half more than seven times!

sharriso74 01-03-06 10:56 AM

Last one is true they tried it on Brainiacs with a huge piece of paper.

mysteryjimbo 01-03-06 11:01 AM

What about that truely awful cheap paper you can get from staples? Something like 60gsm! :lol:

sorry to be an idiot poster........
but ALL supersonic aircraft have a system to 'ramp' air going into the intakes to ensure the air is not going supersonic into the engine.
:wink:

so, yeah.... your comment was quite correct!!!
But... it could be changed to "a jet engine will only work if the air entering is subsonic."

anybody know why supersonic intakes are made square?

Stingo 01-03-06 11:06 AM

A 2p piece weighs the same as two 1p pieces - now that is a staggering fact!! :lol:

mysteryjimbo 01-03-06 11:14 AM

A container filled with small ball bearings has the same amount of air around them as the same container filled with larger ball bearings of the same total mass.

I remember reading that somewhere and i'm pretty sure it applies to 1 pence and 2 pence pieces too! :lol:

Well, thats a given isnt it!

Same mass, same material, same volume :wink:
