Foreign countries seek 'powerful, affordable' CH military series for reconnaissance, combat uses

A number of foreign nations are awaiting delivery of China's CH series military drones, one of the country's most popular products on the international arms market.

The drone family, bearing the name Cai Hong, which means rainbow in Chinese, is considered by experts to be among the most lethal drones on the planet. The newest and largest capacity combat drone in the series, the CH-5, is awaiting government approval for export.

"The total value of contracts we signed in 2015 could definitely be one of the highest in terms of armed drone deals made last year on the international market," Shi Wen, chief drone designer at the China Academy of Aerospace Aerodynamics in Beijing, told China Daily in an exclusive interview. He did not provide a figure.

The academy, part of China Aerospace Science and Technology Corp, is one of China's largest military drone developers. Its CH series drones have been sold to 20 military users from more than 10 foreign countries and are the largest military drone family that China has exported, Shi said.

The early models, CH-1 and CH-2, are small, unarmed reconnaissance craft that have a proven record in locating and monitoring targets. The larger ones — the CH-3 midrange combat and reconnaissance drone and CH-4 mid-altitude, high-endurance armed drone — immediately attracted buyers seeking a powerful, affordable unmanned combat aircraft.

"Our best-selling type so far is the CH-3, while the CH-4 has also received many orders," Shi said, adding that many more countries have expressed a "strong desire" to buy CH drones, but have yet to do so because of their sluggish economies.

Shi declined to disclose which countries have purchased the CH series, only revealing the academy's most valuable sale was worth "hundreds of millions of US dollars".

China Space News reported in January last year that Shi's academy would deliver about 200 CH drones to domestic and foreign users. Earlier reports by Western media cited Egypt, Saudi Arabia, Pakistan, Nigeria and the United Arab Emirates as known buyers of CH drones.

The first contract to export CH drones was signed in 2003 and fulfilled in 2004, when a South Asian country bought several CH-1s, Shi said. Since then, the buyer has become a loyal user of CH series drones and is negotiating the purchase of some CH-4s, he said.

The Chengdu Aircraft Corporation (CAC) revealed a modified version of its Tian Yi (Sky Wing) high-altitude long-endurance (HALE) unmanned aerial vehicle (UAV) in late December that may be designed to have a much reduced infrared signature.

First seen in model form at Airshow China 2006 at Zhuhai, the Tian Yi emerged in mid-2008 at the CAC airfield as a medium-sized single turbofan-powered UAV with V-shaped vertical stabilisers.

It resembles the Northrop Grumman RQ-4 Global Hawk, but is closer in size to the General Atomics MQ-9 Reaper. A small number may be in service with China's People's Liberation Army (PLA).

The new modified version is about the same size as the original Tian Yi, but has a redesigned fuselage. The most prominent difference is a wider empennage that incorporates two smaller turbofan engines plus a wider air intake. These modifications are most likely intended to suppress the UAV's infrared signature, which would stand out against in high cruise altitudes.

In addition, the forward fuselage features more 'stealthy' shaping and a redesigned nose area that may feature a new satellite linkage command/control system.

While the PLA could employ this latest version of the TianYi, it is also possible that it may serve as technology demonstrator for Chengdu's larger Long Haul Eagle. This UAV was revealed in model form at Airshow China 2008 as a larger aircraft similar in shape and size to the Global Hawk.

However, while a full size version of the Long Haul Eagle has yet to emerge, CAC subsidiary Guizhou Aircraft Corporation has produced larger and smaller scale versions of its box-wing Soar Dragon UAV. At the 2006 Zhuhai show this design was revealed to have a weight of 7,500 kg and a wingspan of 25 m, and began to appear at the CAC airfield in early 2012. The smaller version, similar in size to the Tian Yi, emerged in early November 2013.

The emergence of both smaller scale UAVs may indicate they are the PLA's current development priority for CAC.

КНР разрабатывает семейство БПЛА для использования в стратосфере

ПЕКИН, 7 сен 2016, Иван Булатов. Китайские ученые ведут разработку целого семейства беспилотных летательных аппаратов (БПЛА), которые будут использоваться в стратосфере для научных целей, пишет в среду газета China Daily.

По данным газеты, Китайская академия наук ведет разработку беспилотников, которые смогут выполнять длительные полеты на высоте от 20 до 50 километров. План академии на ближайшие пять лет включает в себя 140 научно-исследовательских направлений, среди них разработка ключевых технологий и соответствующей техники для управляемых БПЛА для стратосферы.

Планируется, что тесты на максимальной высоте будут проведены до конца 2020 года. Сферой их использования должны стать, в частности, наблюдение за поверхностью планеты.

При этом директор управления основных научно-исследовательских программ академии Ван Юэчао отметил, что два беспилотника уже были протестированы. "Наши летательные аппараты для стратосферы будут разных размеров, мы уже протестировали два из них. Последний тест был в августе, когда мы совершили пробный полет и достигли наших целей", — сказал он.

Отмечается, что новые БПЛА могут быть полностью автономными.

Китай протестирует "солнечный" беспилотник в ближнем космосе

Пекин, 7 февраля 2017 /Синьхуа/ -- Китай планирует в этом году провести полетные испытания своего крупнейшего дрона на солнечных батареях в ближнем космосе. Об этом сообщила во вторник Китайская академия аэрокосмической аэродинамики .

Дрон "Радуга" с размахом крыльев 40 метров, что шире размаха крыльев пассажирского самолета Боинг 737, уже успешно совершил свой первый полномасштабный испытательный полет, сообщил ведущий инженер проекта дрона академии Ши Вэнь.

Китайский дрон является вторым по размеру беспилотником в мире, работающим на солнечных батареях, уступая лишь модели, созданной НАСА, сказал Ши Вэнь, добавив, что по функциональным показателям и техническим характеристикам он является одним из самых передовых в мире.

Дрон способен летать на очень большой высоте в течение длительного времени и прост в обслуживании, отметил Ши Вэнь.

Он не уточнил детали полета, но сказал, что подобные летательные аппараты способны подниматься на высоту от 20 до 30 километров и летать со скоростью 150-200 км в час.

Беспилотный летательный аппарат будет использоваться в основном для дальнего радиолокационного обнаружения, воздушной разведки, мониторинга стихийных бедствий, метеорологического наблюдения и ретрансляции связи, добавил китайский эксперт.

Lijian Stealth UCAV "Sharp Sword"

23.11.2013 г.

China's first low-observable combat UAV flew for the first time on 21 November 2013, according to local media reports. Named 'Lijian' (Sharp Sword), the Chinese stealth UAV flew for almost twenty minutes, the cjdby.net website reported, followed by Xinhua news agency and other sources.
The People's Republic of China thus becomes the fourth nation to have flown a stealth drone, following the US and others' lead.
It seems the Lijian UAV was first unveiled six months ago, when it was shown carrying out ground trials at co-manufacturer HAIG's (Hongdu Aviation Industry Group's) airfield. Apparently, the Sharp Sword is a joint venture between Hongdu and Shenyang. A single-engined, tailless design, it part-resembles other UAVs including the Northrop Grumman X-47B and the MiG Skat.
China's adoption of stealth technology - as used in the Northrop B-2 (Stealth Bomber), Lockheed F-117A Nighthawk (Stealth Fighter) and other types - has been rapid in nature. In September 2012, the Shenyang J-21 - China's second stealth jet in as many years - was shown to the world. And, just last month, plans to develop long-range strategic stealth bombers were made public.

Once in service, the Lijian will reportedly work within the naval arena, equipping both the PLAAF (People's Liberation Army Air Force) and the PLAN (People's Liberation Army Navy). That's according to Xu Guangya, from the China Arms Control and Disarmament Association who, in comments quoted by the South China Morning Post, explained that the Chinese stealth drone will carry out both combat and reconnaissance.
"The drone, which is capable of flying undetected at high altitudes while providing high-resolution video and other intelligence, will let maritime departments keep abreast of developments in the East and South China seas and will help Beijing make accurate decisions when dealing with territorial disputes with its neighbours", he added.
Lijian Stealth UAV
Based in Nanchang, Hongdu is a leading Chinese aircraft manufacturing group. Previously named after its home city, the company adopted its current title in 1998. The Shenyang Aircraft Corporation was established in 1953 and has produced numerous fighters and bombers over the past 60 years.
Stealth is the branch of military technology concerned with concealment and deception, rendering aircraft, warships and missiles less visible on enemy radar screens. Basic stealth technologies might involve misleading paint schemes - more advanced approaches draw on specialised layouts, plus infrared and radar cross section signature reduction methods
