Quite a fearsome looking Chinook. I almost want to see it turned into a gunship like the ACH-47.
 
MH-47G is arguably the most high-tech helicopter on the planet with all of the new gear.

China offers Taiwan colonel US$15 million to defect via CH-47 Chinook | Taiwan News | 2023-12-11 17:22:00

Why China offered a Taiwan army pilot $15 million and ticket to Thailand?

Taiwanese pilot was approached by Chinese officers who asked him to fly a CH-47F Chinook helicopter to a Chinese aircraft carrier in the Taiwan Strait

As part of the plot, the pilot was also allegedly offered safe passage for his family to Thailand should a Chinese invasion of Taiwan occur.

Worth saying that this is the same order that was first announced in 2021, but was subject to review and much speculation last year - allegedly with Ben Wallace almost cancelling the order as being bad value for money. Interesting to see the added value in today’s release.
 
Interesting to read also that the order is needed to offset the loss in capacity from Hercules retirement.

The logic in that escapes me.

The argument will be that the continued operation of 1/2 of the Hercules fleet was primarily for special forces mobility. This buy is meant to be SF optimised, hence going for the long range fuel tanks to give something akin to a MH47-lite.
 
MH-47 is a great Special Forces platform. It can fly even greater distances with air refueling (usually provided by *cough* C-130). It can fly great distances at 150 knots. So, it isn't going long distances fast. If it is in theater, not sure there is a better platform. If you have to fly from, say Mildenhall to Niger to rescue humanitarian assistance folks you might want to use a C-130 or CV-22B. I don't say this to be critical of the decision taken on by the UK to buy Chinook for SOF operations, but more the decisions to retire all C-130. A400 is also a great aircraft but I suspect bit harder to maintain and certify the "normal" amount of special gear that usually ends up bolted onto Special Purpose aircraft.
 
Yes, none of them are substitute to the other. That's why it doesn't make much sense. You need C-130 and Chinooks.

Brits should probably have rejoined the joint C-130 Squadron with German and French forces.

-47G pilots have to manage their gross weight very carefully because all the extra mission equipment makes empty weight much higher than a -47F. For basic hauling, the -47Gs are not ideal; they really need upgraded engines and debugged Advanced Chinook Rotor Blades.

The CH-47 was already tested with a set of wing mounted in the center fuselage and experiments showed that there was no advantages in term of efficiency (with in fact a significant loss during hover and slow speed flight). thanks to the tandem rotors having overlapping discs. See Boeing BV-347

Fill me in on debugged Advanced Chinook Rotor Blades. What are the issues?

Thanks - Mark
 
I always wonder, why the front set of wheels are dual configuration, while the rear are single wheels ....
 
Regarding Piasecki proposal, how does it stand structurally? is there a carry through main spar acting as a pivot (tube?) crossing the cabin? I mean, I would have understood if the wing was low mounted but there?!!
 
Weight. The CH47 series is near its structural design limit. More kit means less cargo. I am not sure what the Piasecki concept adds to the weight of the aircraft, but suspect it is considerable. So you could end up with a Chinook that can carry slightly more than a Blackhawk to a longer distance. Not sure that would be considered a wise move.

So it can manoeuvre on the ground... The first Chinook prototypes (and early A models) did have dual wheels in the rear; however, they did not work well. The narrow high pressure tires did not turn easily on a short radius, especially on grass or rough terrain. A larger single tire worked much better.O

Excessive vibration at cruise speeds, enough so that the crews were getting nauseous and forward flight was limited to something like 130kts. The ACRBs were great for increasing lift capacity, but obviously the huge tradeoff was speed in forward flight.
