A full-scale prototype of a new-energy aircraft, the ET480, developed by the research center under the Commercial Aircraft Corporation of China (COMAC), rolled off the production line recently, according to the Securities Times on Tuesday.

The plane, which was co-developed by COMAC Beijing Aircraft Technology Research Institute and a firm under State Power Investment Corporation, is aimed at future urban transportation.

It has a composite wing configuration and can cruise long distances. It also has the flexibility for vertical take-off and landing. In terms of energy, the aircraft uses a "fuel cell + lithium battery" electric-electric hybrid power system and it is expected that the cruising range can be about twice as long as for traditional lithium battery aircraft, the report said.

The carbon fiber composite materials used in the structure account for more than 90 percent and the aircraft uses 5G-based intelligent unmanned driving technology, according to the report.

AC352 has been flight testing since Soviet Union collapsed
The Airbus Helicopters H175 is a 7-ton class medium utility helicopter produced by Airbus Helicopters (formerly Eurocopter Group). In China, the H175 is produced by the Aviation Industry Corporation of China (AVIC) as the Avicopter AC352. Originally launched as the Eurocopter EC175 and the Harbin Z-15, it has been referred to as being a 'super-medium' helicopter.

Formally launched at Heli-Expo in Houston on 24 February 2008, it was predicted by Airbus Helicopters that approximately 800 to 1,000 EC175s would be sold over an initial 20-year period.[2][3] It entered service in December 2014; in 2015, the EC175 was formally renamed to the H175, in line with Eurocopter's corporate rebranding as Airbus Helicopters.[4]

On 4 December 2009, the EC175 prototype made its unofficial first flight;[11] the official maiden flight of the prototype was on 17 December 2009 in Marignane, France.[12] A two-year delivery delay was encountered, partly due to certification issues with the rotorcraft's Helinix avionics suite.[13] The European Aviation Safety Agency (EASA) were originally expected to issue type certification for the EC175 sometime in 2013; this was formally received in January 2014.[14] In September 2015, Avicopter publicly revealed their first AC352 prototype.[15] In December 2015, flight tests of the Turbomeca Ardiden 3C/WZ16 powerplant were performed using an H175 prototype.[16]

An initial assembly line for the EC175 was established at Airbus Helicopters' Marignane facility; in 2008, it was reported that a second assembly line for the type was intended to follow within five years.[17] In April 2014, an agreement between Airbus Helicopters and Avicopter was made for the production of 1,000 EC175; lasting for 20 years, manufacturing is split half-and-half between separate assembly lines operated by the two firms.[18][19]

China's indigenously-developed large passenger plane C919
completed its first low-temperature flight test in North China's Inner Mongolia Autonomous Region on Saturday.

The C919 jet took off from
Hulunbuir Dongshan International Airport in the region, and landed at Dongying Shengli Airport in East China's Shandong Province, completing 23 days of tests.

The low-temperature test is an extreme weather flight test that civil aircraft are required to clear-- aimed at testing the functions and performances of the operational systems and equipment of the aircraft, experts said.

During the flight test, 10 aircraft experiments and four ground experiments related to C919 were verified as meeting standards in a
low temperature environment of -35C.

To complete the flight test, Hulunbuir Dongshan International Airport worked with related departments and companies including local airport supply and air control department and China National Aviation Fuel Group Limited (CNAF). Hulunbeier Meteorological Service also placed five sets of meteorological monitor equipment to ensure the precisely climate data during the test.

C919 jet is China's first independently developed jumbo plane with own intellectual properties, experts said.

China's C919 jet begins cold-weather test flights in Inner Mongolia

Published: Dec 26, 2020 09:49 AM

China's indigenously-developed C919 large passenger aircraft has started cold-weather test flights in Hulunbuir in north China's Inner Mongolia Autonomous Region.

The plane arrived at the Hulunbuir Dongshan international airport Friday for the test which is expected to verify the performance of the aircraft's systems and equipment in extremely cold weather.

The test flight team from the Commercial Aircraft Corporation of China, the manufacturer, said the aircraft is conducting coordinated test flights at multiple airports in multiple regions.

Hulunbuir was chosen for the test flights as the city is known for its cold weather, with an average temperature of minus 25 degrees Celsius during winter. The city has also attracted many other equipment makers to conduct cold-weather tests.

Manufacturing of CR929 plane to start in 2021: COMAC
By Global Times

The long-range wide-body aircraft, CR929, to be jointly developed by China and Russia, will kick off its manufacturing in 2021, said Yang Zhigang, general engineer of Commercial Aircraft Corporation of China Ltd (COMAC).

Yang said that the start of CR929 construction means the entire design phase, including the specific shape, size, material, operation systems and various parts suppliers of the aircraft, will be "frozen".

"For the core systems of the CR929, we wish to be supplied by two or more companies," said Yang. He noted that they can phase in an insurance mechanism to ensure the continuous operation of the business, something most civil aviation companies in the world usually adopt.

According to the official website of COMAC, CR929 is a dual-aisle plane to be jointly developed by China and Russia, initially oriented toward the markets in China and Russia, while extensively meeting the global market demands of international and regional air passenger transport.

Meanwhile, the production of the regional aircraft ARJ21 and the large jet aircraft C919 are also underway.

The ARJ21 aircraft is the first short-medium-range turbofan regional aircraft independently developed by China, according to the COMAC official website. More than 20 ARJ21s were manufactured in 2020 and there are currently almost 50 ARJ21s serving the aviation market, adding more ARJ21 aircrafts will be completed in 2021.

China's domestically-developed large passenger aircraft C919 is undergoing frequent flight testing in different areas of China. On 16 January, C919 completed its first low-temperature 23-day-flight test in Hulunbuir of North China's Inner Mongolia Autonomous Region.

"The C919 aircraft is scheduled for delivery to the first client at the end of 2021," said Yang.

[C919 completes the first flight certification test]

At 15:25, January 22, C919 104 aircraft landed and taxied at the airport of the China Flight Test Research Institute, marking the successful completion of the first flight certification test of the C919 aircraft. The flight test certification of the C919 aircraft officially began, and the airworthiness certification work has entered a new stage.

According to the plan, during the flight test stage of the CAAC certification, more than 430 flight test subjects including stall, natural icing, and crosswind flight tests will be carried out for compliance verification tests for the C919 aircraft. That is to comprehensively inspect and vet the aircraft design, and to lay the foundation for the C919 aircraft to finally obtain the type certificate and induct into line operation.
