China's transport, tanker & heavy lift aircraft

Some camera tricks there. As the Y-20 was making the turn, the camera was being turned around. Still, the banking angle looks to be close to 80 degree.

Exactly. The point is that the Y-20 makes a horizontal (although banked) loop while the C-27J does a vertical loop, otherwise known as a loop-de-loop.

That being said, I doubt it's even possible for an aircraft of the Y-20's weight class (especially with current engines) to complete a true loop-de-loop, for the demands put on propulsion and stress on the airframe would likely be too massive.

I have seen at Farnborough an A380 doing a full vertical loop. The thing looked so fat on the runway that a lot of people in the crowd actually was surprised that its take off looked so easy and in relatively short distance, and then gob-smacked when it started doing loops and all sorts of acrobatics in the sky. Unbelievable.

Flies like a dream.

I noticed on other sites that the wingspan is longer than its length, 50m to 47m, unlike the C-17. Maybe, this is the reason it does not have winglets. But so does the Il-76.

mi-26t2-01.jpg

Exisitng Russian Mi-26. The proposed helicopter will be significantly larger.

Foxtrot Alpha said:
China And Russia Team Up To Build World's Largest, Most Powerful Chopper.

Currently, the largest and most powerful helicopter to have ever entered production is the gargantuan Mi-26 'Halo' of Russian origin, of which many still serve in governmental and commercial roles around the globe. After decades of the 'Halo' being on top, a new record holder is now said to be on the way, with Russia and China joining forces to make it happen.

This new super-heavy lift class chopper was originally thought to be an outgrowth of the existing, all-weather capable and highly modernized Mi-26T2, but now it seems that it will only borrow a few elements from it, and will overwhelmingly be a 'clean sheet' design.

The fresh design approach is due to China's eye popping requirements. According to Russia, they are said to include almost twice the lifting capacity of the already freakishly powerful and huge Mi-26. That would put the new chopper's lifting ability at somewhere around 80,000lbs! In comparison, the CH-53K 'King Stallion,' America's latest heavy lift design, has a total gross weight just slightly above that figure at 88,000lbs.

Originally, this new Russian-Chinese design was thought to be an outgrowth of the Mi-26T2, although this is now inaccurate as Chinese performance demands are far outside any existing designs' theoretical capabilities.

The Mi-26 can already haul vehicles that are larger than what can fit even into a C-130 Hercules, including everything from armored personnel carriers to dump trucks. Yet China has had a uniquely large demand for heavy under-slung cargo carrying ability, for both construction and logistical purposes and there has been talk for the last decade or two about how a super-heavy lift helicopter could change the way some structures are built. This is especially true for modular vertical oriented structures that are intended to be built fast and replicated quickly, an area of architecture and construction that China continues to be the leader in.

According to Russian reports, multiple Chinese agencies are part of this new mega-chopper procurement program, including those that deal with emergency management and response. This makes some sense as during a natural disaster, or even a time of conflict, moving massive amounts of supplies quickly will be all that much more critical considering China's massive population.

A cost has not been publicly assigned to the program, nor has there been word regarding what percentage Russia will share in the costs of developing such an exotic machine. Regardless of the public absence of some details, Russia says this new design requirements will be locked by the first quarter of 2015.

Exisitng Russian Mi-26. The proposed helicopter will be significantly larger.

It's a bit embarrassing to see foxtrot alpha peddle incorrect information. it is the helicopter's MTOW which is in the 38 ton class, not its payload.

One of the recent and original reports. The title is quite explicit, but through the grapevine the important bit (underlined) has been filtered out.


Russian-Chinese heavy helicopter will have take-off weight of 38 tons - Rogozin


Russia and China have reached an agreement in principle on a joint project to create a heavy transport helicopter, said Deputy Prime Minister Dmitry Rogozin.

"For heavy helicopters moving normally. Treaty to the helicopter on 38 tons," - said to "Interfax-AVN" Rogozin.

According to him, it was decided that "Russia's contribution to the project will be material, our technical capabilities."

Previously CEO of the holding company "Helicopters of Russia" Alexander Mikheyev said "Interfax-AVN" that technical configuration of the Russian-Chinese heavy helicopter will be determined before the end of the year.

"Hopefully, this year we define the technical configuration of the helicopter and the status of the project," - said A.Miheev.

According to him, the Russian-Chinese heavy helicopter is planned to create on the basis of the technological platform of the heaviest in the world of the Mi-26, produced by "Rostvertol" (part of the holding company "Helicopters of Russia").

He noted that the new car will not be analogue or further development of Russian heavy Mi-26 helicopter. "This helicopter will be developed specifically for the Chinese market, to perform the missions that are formulated by various ministries and agencies in China. Primarily the Ministry of Emergency Situations," - said A.Miheev.

Well, we do not really know the complete specs for this new helicopter. But if it is bigger than the M-26 Halo...it is going to be HUGE. The Mi-26 is already significantly larger than the largest US helicopters in services (the CH-52E Super Stallions and MH-53E Sea Dragons) and also larger than the planned CH-53K King Stallion.

Here are some comparisons:

Russian: MI-26 Halo, 316 built
Length: 131 ft 4 in
Rotor Diameter: 105 ft
Height: 26 ft 9 in
Engines: 2 x D136 turboshafts, 11,400 shp each
Cruise Speed: 158 mph
Range: 1,190 miles
Service Ceiling: 15,100 ft.
Crew: 5
Capacity: 90 troops or 60 stretchers, 35,000 lbs
Empty weight: 62,170 lbs
Max Take-off Weight: 123,450 lbs

US: CH-53E Super Stallion, 234 built
Length: 99 ft
Rotor Diameter: 79 ft
Height: 27 ft 9 in
Engines: 3 x GE316A turboshafts, 4,380 shp each
Cruise Speed: 170 mph
Range: 620 miles
Service Ceiling: 18,500 ft.
Crew: 5
Capacity: 55 troops, 30,000 lbs internal, 32,000 lbs external
Empty weight: 33,226 lbs
Max Take-off Weight: 73,500 lbs

US: MH-53E Sea Dragon, 50 built
Length: 99 ft
Rotor Diameter: 72 ft 3 in
Height: 28 ft 4 in
Engines: 3 x GE316A turboshafts, 4,380 shp each
Cruise Speed: 172 mph
Range: 1,120 miles
Service Ceiling: 27,900 ft.
Crew: 8
Capacity: 30,000 lbs internal, 32,000 lbs external
Empty weight: 33,226 lbs
Max Take-off Weight: 73,500 lbs

US: CH-53K King Stallion (Ground Test Prototype delivered in 2013, Flight Tests planned for 2015) 227 planned
Length: 99 ft
Rotor Diameter: 79 ft
Height: 27 ft 9 in
Engines: 3 x GE381B turboshafts, 7,500 shp each
Cruise Speed: 196 mph
Range: 600 miles
Service Ceiling: 18,800 ft.
Crew: 5
Capacity: 55 troops, 44,090 lbs internal
Empty weight: 33,226 lbs
Max Take-off Weight: 84,700 lbs

But those US Marine CH-53Es do operate off of US Navy LHDs so that is one of the principle differences. the Mi-26s would simply be too big for that.

The Navy Sea Dragon mine hunter has been configured for higher altitude and longer range for its sea duties.

The main thing the US will get with the CH-53K is more powerful engines, faster speed, and a little more weight carrying. Still far smaller than the Halo.

^ That's the thing; I sincerely doubt it will be larger than the Mi-26.

The original articles on the matter say a 38 ton TOW helicopter, not a 38 ton payload helicopter.

If anything, this new helicopter is China's own Ch-53K. It makes sense for China to want a heavy lift helicopter that they can adapt for LHA use.
