For helicopter top speeds, wasn't the Boeing 360 "SuperPhrog" well in excess of 200 knots and close to the Lynx? 214 knots advertised if I remember correctly.

Phrogs Phorever!

46driver,

Just like the unofficial, sort of documented altitude claim, one must give credit to the party that chose to expose the attempt to independant proof, using the FAI.

While Boeing's claims were reported in the press, the 360 never did anything for the FAI. Knowing those Boeing folks as I do, I would bet they would have set the record were it possible.

Nick,
Just out of curiousity, do you know the maximum speeds for the H-60, CH-47, and CH-53E? I would assume that the CH-53E is that fastest?

46driver,
Unfortunately, I can't tell, as it would be very unwise to advocate going beyond Vne. PM me ok?

I did find some old press reports that said 230 mph and even one at 246 mph for the B-360. I believe it, when you think of an advanced Chinook drive train in a Sea Knight body!

Cool H-53 Speed

During an engineering evaluation of the CH-53E to validate power requirements for a proposed new medium lift helicopter we achieved 196KIAS in level flight at a maximum continuous power of 137% approximately 13000 Hp. This was a production pure stocker with EAPS but no aux tanks.
