| T333 Helicopter cargo UAV. Beijing-based Zhong Hang Zhi Technology (ZHZ) exhibited a new coaxial dual-rotor UAV dubbed the T333 at the biennial 11th Zhuhai Air Show, along with an upgraded variant of the TD220 coaxial dual-rotor unmanned helicopter. |
Zhong Hai Zhi
Technology, a private Chinese drone builder, showed off its 3-ton T333
Helicopter cargo UAV. T333 has a payload of 1.5 tons and speed of 300
kilometers (or about 186 miles) per hour. The UAV has a non-bearing composite rotor, H-type tail and retractable three-wheel landing gear. Compared to conventional
helicopter layouts, its coaxial rotor saves weight and increases speed.
At 3 tons, it is the largest purpose-built helicopter drone (some
conversions like the K-MAX are bigger) in the world.
While the smaller T220 is already in service with Chinese civilian and military customers, the T333 may be joined by even bigger cousins in the years to come. Chinese military users would find that the T333's small size and respectable payload well suited for both unmanned aerial resupply of Chinese troops in difficult-to-reach mountain and urban areas, as well as for naval uses, like anti-submarine warfare, on warships too small to carry manned helicopters.

Elsewhere, the TD200 has undergone a design makeover that conceals its external gimbals and sensors, though the aircraft retains its coaxial dual-rotor and H-type tail. Despite its structural changes, the UAV’s range, weight, endurance and speed remain the same.
The first time the TD220 made an appearance at an Asian show was at the 2014 Singapore Air Show, where the aircraft was promoted for civil and commercial surveillance missions.
During the 2014 Singapore Air Show, ZHZ also promoted the TC unmanned helicopter for commercial surveillance and patrol missions, but the aircraft was absent in Zhuhai in 2016.
One of
the true stars of Zhuhai 2016 was the C919 jetliner, China's modern
passenger jet, which garnered 56 orders at the event. Following on the
much-delayed regional ARJ-21 jet, the 75-ton C919 is in the same class
as the Boeing B737 and Airbus A320, seating up to 156 passengers in its
basic two-class configuration. It has a wingspan of 117.5 feet and a
length of 130.6 feet.
After a couple of years of delay, the first C919 prototype rolled out of the Commercial Aircraft Corporation of China's (COMAC) Shanghai factory in November 2015, and is undergoing extensive ground testing before its maiden flight in the first half of 2017. While most of its 573 current orders are from Chinese airlines, the global success of the C919 as a lower-cost alternative to western aircraft would be a political and technological triumph for China. In addition, experience from the C919 will give COMAC the base to build larger next-generation jetliners.

In addition, experience from the C919 will give COMAC the base to build larger next-generation jetliners.
The C929 will have a range of 7,456 miles and will have three variants, seating 250, 280 and 320 passengers respectively. This would roughly place the C929 in the same weight class as the Boeing 787 and Airbus A350. China and Russia hope that combining Chinese resources with past Russian experiences, along with foreign inputs like western Rolls Royce and General Electric engines, will help them produce a high-tech jetliner that's 10 percent cheaper than its western competitors. In addition to providing a cheaper option for civilian long haul flights, the C929 could serve as a fuel efficient platform for large Chinese or Russian military aircraft like airborne early warning command and control, aerial tankers, surveillance, electronic intelligence gathering, and VIP transport.
The
world's largest military aircraft currently in production, the Y-20, is
China's heavy transport aircraft. Built by the Xian Aircraft
Corporation, it has a maximum takeoff weight (MTOW) of 200 tons and a
66-ton payload, and is entering People's Liberation Army Air Force
(PLAAF) service this year.
The Y-20 made a repeat appearance at Zhuhai 2016 (it debuted at Zhuhai 2014) as the Y-20F-100, which can carry 28 air freight containers with a total weight of 65 tons—enough to transport high bypass domestic WS-20 engines. In addition to increasing its fuel efficiency, this means that China would not need Russian approval to export the Y-20F-100.

AG-600 and Y-20
The AG-600 seaplane (in front, white, grey and blue paint scheme)
and Y-20 military transport (in the background in dark grey), both the
largest in the world of their type still in production, were some of the
top draws at Zhuhai 2016.
The
debut of the CAIGA (an AVIC subsidiary) AG-600 seaplane prototype was
one of Zhuhai 2016's pleasant surprises. With a maximum takeoff weight
of 53.6 tons and room for 50 passengers, the AG-600 is the world's
largest seaplane, beating out the Japanese U-2. By the end of the show,
AVIC claimed to have received 17 orders for the AG-600 from domestic and
foreign customers. Here's why: large seaplanes are well-suited for
firefighting, maritime search and rescue missions, anti-submarine and
littoral irregular warfare, and resupplying small island bases, like
those in the South China Sea. popsci.com
