I wouldn't be surprised if Germany also hops on the French interest for the Chinook, so that both forces will have a joint fleet just like with the joint Franco-German C-130J Super Hercules squadron based at Evreux, France. But I really want to know, how well the CH-47 performs with the GE T408 engines of the CH-53K.
The NCH-47D Chinook testbed helicopter has flown for the first time with the more powerful GE T408 engines of the CH-53K. :cool:

Let's not forget that Chinooks still fly with a symmetrical airfoil that could need to be replaced to get use of all that extra power (50% more). Otherwise engine swap won't affect positively any perfs, except, probably, fuel consumption.
(the last rotor modernisation brought only minor improvements)

The CH-47Z will be silently sailing around on anti-grav in 2120.

You think small. Historical documents from the future show that the Chinook will still be in service well past the year 3000.

Would there be an advantage to replacing the rotor system with one with more blades?

Are you saying the fuselage shape should change? If so the whole helicopter should be replaced w/ one of the sleek designs boeing has shown before.

I was more thinking at the blades of the rotors that still have a Naca symmetrical airfoil. With such power increase, the only way that it could be of any use is if the blades are flown at an increased pitch. With adapted blades, that would not be the case given that a proper redesign is done.

The ACH-47 "Armed/Armored Chinook was always proof positive that the Chinook was too small to support armed insertion of troops into hostile LZs. One could not supress hostile fire and still carry troops. One had to make a choice.

iv seen mention of a possible ASW. variant of CH-47 (also mentioned in UK. sources), did this get beyond musing to actual studies or brochure proposal ?

cheers, Joe
