Sold to France and expected to fly in May at la Ferté Allais

Now Now Now Dear Col. Rohr,

You proclaim affection for only things round, yet at Geneseo you abandoned your radial beauties to come to the aid of poor SL721 when she was in distress. I think you might have a secret affection for things pointy! :lol:


To the Brits,

Keep up the ejumatation! I've always viewed the Spit as a great plane. But the more I learn the more my appreciation grows.

Question number 496.

I was reading the link Mrhenniger provided, and found this,

Seafire 47: 451 mph (724 kph)


Dayyam! Have these been taken to Reno?

I think that speed is at altitude, down low those big radiators create a lot of drag compared to the p-51 scoop which is a lot smaller. I also heard that the scoop on the mustang actually creates a bit of thrust.

Mike,

The Spitfire also used a ducted radiator design to utilise the 'The Meredith Effect' to generate thrust. Initially with a two position manual flap, to regulate temperature, it was not as efficient as the P-51, but then it was designed in 1935. I believe the efficiency was improved as the aircraft was developed through the marks and that those massive droopy Griffon radiators were not quite the impediment they might first seem.

I know, I weakened just once. :wink:
I've had young Shreeve pointing out the holes in my Supermarine knowledge all day (Robbo too). :oops:

Perhaps we should get a Hawker thread going. :?
