A two-stage supercharged Wright R-2600-10 rated at 1,700 hp for takeoff and 1,380 hp at 21,500 feet powered the Grumman XF6F-1 Hellcat prototype (all subsequent Hellcats employed the P&W R-2800).

I've just come across this very interesting post. It would be great to see the whole report. Cheers

Excellent - thank you.

Thanks MiTasol - Marvellous! And it would be great to see also the 1945 Report of the Farren Mission to study German aircraft, aircraft engine and armament industries, held at the National Archives Kew as AVIA 10/411. Can someone post it?

- Adopt the MG210 to supersede the 151, using the same ammunition - 15mm or 20mm. The 210 was designed by Mauser to do just that, employing gas in place of recoil operation. Rof 1000 vs 700 rpm, weight 32 vs 42 kg, power/weight ratio 1.875 times better (and iirc about 300mm shorter). - For a...

The late P-38 had hydraulically boosted aielerons which enabled it to outroll every other fighter. Impressive if one consider its size. Now the Fw 190D-13 had them, too. It should roll even better as it is much smaller. Any other fighter which featured those? The Dornier Do 335 Pfeil: Flying...

The J52 axial being a lot slimmer than the J48 centrifugal would make a lot of Cougar fuselage volume available around the cg for fuel.

The Canadair Sabre F Mk 4 which entered RAF service in May 1953 was barely competitive (if that) with the MiG-17. It was replaced in RAF service by the Hawker Hunter starting in June 1955, by when the supersonic MiG-19 had already entered Soviet service three months earlier. Although afaik the...

At sea level the A-8 on 1.58 ata had about 1930 PS on tap and the A-9 on 1.65 ata had 2000.

So? (Actually IIRC the nuclear capability was limited to the central fuselage station which originally provided for a capsule insertion).

An airframe's nuclear capability was no obstacle to foreign sale; the A-4 Skyhawk for example was sold to numerous air arms including 278 to Israel. The Skyhawk was purpose-designed for nuclear delivery among other options. And the F-101B Voodoo was not only designed to carry Genie nuclear...

"If you have two and lose one you still have one to get you home" was a slogan used in advertisements for the F4 Phantom II in the sixties and seventies, its perceived competitors being single-engined. The F-106 Delta Dart could have been powered (and likely much improved) with the Canadian...

"Dietmar Hermann mentions in his "Long Nose" book(it may have been the Ta 152 book) that that Focke-Wulf latter made a miscalculation in the weight of the Jumo 213 versus DB603 engine that made the DB603 seem 140kg or so heavier. But for that error the Fw 190D may have been flying with a...
