Shenyang Institute of Automation of Chinese Academy of Sciences (CAS), recently completed test flights of Xiangying-200 unmanned helicopter and it has now entered its acceptance stage.

The key components such as the control system, power system, transmission system are all domestically developed, indicating that the independent research and development ability of China's large unmanned helicopter has been further improved.

According to Gu Feng, an associate researcher at the institute, Xiangying-200 was jointly developed by Shenyang Institute of Automation and several units of CAS. It's 8.7 meters long, 2.5 meters high and can carry a payload of 200 kg.

Researchers made breakthroughs in the key technologies such as autonomous flight control, deck take-off and landing, marine protection, lightweight materials and engines.


The unmanned helicopter has fulfilled the autonomous takeoff and landing on a ship deck for the first time among unmanned helicopters of its size and with domestic engines.

With a wide application perspective, the unmanned

by the institute have been used in many important events, such as Antarctic scientific research and Lushan earthquake rescue in 2013.

CASC highlights enhanced CH-804C hybrid UAV

The China Academy of Aerospace Aerodynamics (CAAA), the flight technology development arm of the state-owned China Aerospace Science and Technology Corporation (CASC), has developed an improved version of its Cai Hong 804C (Rainbow 804C, or CH-804C) hybrid fixed-wing/vertical take-off and landing (VTOL) unmanned aerial vehicle (UAV).

The updated air vehicle features a redesigned composite airframe with an increased wingspan of 4.25 m, a maximum take-off weight (MTOW) of 30 kg, and a payload capacity of 4 kg. In contrast, the earlier model had a MTOW of 25 kg with a 4 m wingspan, and could only carry a 3 kg payload.

According to specifications viewed by Jane’s, the primary payload of the CH-804C comprises a belly-mounted 2.5 kg optically stabilised electro-optical/infrared (EO/IR) ball turret with a daylight channel providing wide and narrow fields-of-view (FoV) of 46°x34.5° and 4.6°x3.45°, respectively.

It is stated to be capable of detecting a tank-sized object at a maximum range of 2 km and identifying it at distances of up to 1.5 km. The IR channel is equipped with a 640x512 pixel resolution and 13.9°x11.2° FoV focal plane array, and has a claimed detection and recognition range of 1.5 km and 1 km respectively.

CAAA engineers have also boosted the CH-804C’s flight endurance to four hours, a 33% improvement over the earlier model. The air vehicle is equipped with an L-band datalink that enables it to transmit and receive data within a 100 km line-of-sight distance, supporting a data transfer rate of up to 25.6 kbps for telemetry and 4 Mbps for imagery.

The CH-804C also employs a dual global positioning system (GPS) receiver suite that offers redundancy in the event of signal loss in one of the GPS modules, and also enables GPS differential computation for improved positional and hover accuracy. This also reduces the reliance on its inertial navigation system (INS), which can be degraded by interference from power transmission lines as well as environments with strong electromagnetic fields during low-level flight.

We know that the program of the Chinese military drone Wing Loong II had won at least one export contract even before the first prototype made its inaugural flight, which dates back to February last year, while according to its AVIC manufacturer Chengdu the first copy has already been delivered as early as the month of October. But what is still unknown today is who bought and the details of these contracts.

If we still do not have the precise answer to these last questions, apart from the fact that the KAUs seem to have received their first batch of delivery, we still know that a hundred devices have already been sold so far.

In fact, according to a television report of the Chinese national channel CCTV-13 on August 1 this year, "more than 100 Wing Loong II drones are sold today in the international market" but no other details 'has been disclosed. The show focused instead on what China calls "civil-military cooperation," a concept that is largely applied to the mass production of the Chinese armed drone.

In Chengdu, where the drone was designed, we can see on the assembly line several aircraft that are being final assembled while others, in pale gray livery, are in the hangar waiting to be tested. .

We then learn that the 300 or so private companies, which account for about 50% of Tier-1 suppliers in the program, had a difficult adjustment period to acclimatize to military processes and its much stricter standards than they have to do so far on civilian products.

In return, they benefit from a certain level of technology transfer and integrate into a more global industrial chain, while becoming more competitive, while the state- owned aircraftmanufacturer Chengdu Aircraft Corporation (CAC) takes advantage of the workforce. to increase its production capacity and improve the sense of service through private sector feedback.


The Institut 611 and Factory 132 CAC today manage more than 100 external suppliers for the supply of the 130 subsystems of a Wing Loong II drone. The production line currently has a hundred or so staff, most of whom are engineers, for a current production rate of 24 aircraft per year.

Chinese aircraft manufacturers plan to

to increase their design and production capacity, and reach the pace 30 in the near future in Chengdu.

According to figures released by JI Xiao Guang (季 晓光), director of the 611 Institute, which deals with the design of the J-10 and J-20 fighters, Wing Loong I, II, ID and III drones could generate up to 15 billion yuan of income, or about 1.9 billion euros at today's exchange rate, over the next five years.

The first delivery of the Wing Loong II to the foreign customer.

Four times heavier than the previous Wing Loong I, which made its first flight in October 2007, the Wing Loong II, with a maximum takeoff weight of 4,200 kg, has made China the second-largest country in the world capable of build a Medium Altitude and Long Endurance (MALE) armed drone in this template.

This new version is 11 meters long, 4.1 meters high and 20.5 meters wide. It is capable of flying up to 9,000 meters above sea level, with a top speed of 370 km / h. With a larger size and a new turboprop of Chinese origin, the Wing Loong II can carry 480 kg of weapons on its 6 points of carriage, ie 12 ammunition Air-Sol in total, for missions of identification and typing.

For reconnaissance missions, it can count on a complete optronic suite equipped with TV, IR and laser channels, as well as a Synthetic Aperture Radar (SAR). The autonomy of the drone is given at 20 hours in flight when the device is fully armed.

"The Wing Loong II is at the same level as the American UAV MQ-9 Reaper, " said LI after

, "We are competing with the best drones in the world in the same category , with our own technologies, and we could surpass them in the near future. "

The potential size of the export market for Wing Loong drones is estimated at "several hundred" aircraft, according to the chief engineer of the Chinese design office.

Jane's as a short preview of an article up about a Digital Globe shot of Malan AB. There are apparently a number of UAVs on the tarmac. Amongst them is an unknown object. Jane's is suggesting it is one of the high speed UAV projects China is working on. The DG pix in support were taken on June 7th and June 10th

Unfortunately, I don't have the spare cash at this point to see the rest of the article. Nor has Jane's placed the pic in the public portion of the article either.

Anyone happen to have a link to the image, whether or not its on Jane's site?

PS if it better according to forum decorum to NOT put the full link, please, let me know. Some folks I have found online are rather uncomfortable clicking on links they do not see what they are rather than a hypertext link. Thanx.

That looks like it what was described.

Thank you.

The Jane's link has gone 404 now. Good thing I have it still had a tab open.
