BZK-008 CH-91 WZ-8 Hypersonic Drone Testbed

A grand military parade was held in Beijing on 01 October 2019 to mark the People's Republic of China's 70th founding anniversary. China said the parade, the countrys most important political event of the year, which featured more than 15,000 troops marching through part of Tiananmen Square as jet fighters trailing colored smoke soared overhead, was not meant to intimidate any specific country. But it was a message to the world that Chinas military prowess is growing rapidly, even as it faces mounting challenges. Military Parade Deputy General Manager Tan Min, at a press conference the week before the parade, 'All the weapons exhibited in the parade active service.' had used. This statement shows that the aircraft is actively used by the Chinese armed forces.

This high-speed Chinese drone, which reportedly first flew in September 2015 is launched from an H-6 carrier aircraft, the drone fired up its combined cycle turbo-ramjet engine to accelerate from subsonic to high-supersonic speeds. Tentatively identified as the WZ-8, it could be equipped with a scramjet to test combined cycle hypersonic engines.

TSC Beijing, one of the world leaders in 3D printed metal aviation parts, has achieved significant time and cost savings by 3D printing this titanium center fuselage box for a "high-speed" Chinese drone.

TSC Beijing, a Chinese titanium manufacturer, successfully 3D printed a titanium fuselage central box for its high-speed aircraft, which cuts production time from two years down to just six months. TSC used the 3D laser printer TSC-S4510 (one of the world's largest 3D printers) to print the fuselage, within an error tolerance of less than 0.5mm. The intended aircraft was identified only as a "high-speed" (read: hypersonic) aircraft. Given its narrow wing roots, and 23-foot total length, it is likely a hypersonic UAV.

One likely candidate for the titanium airframe is a single engine, high-supersonic UAV with narrow wings and a needle-like airframe. Possibly designated the WZ-8, it is believed to be an air-launched UAV used to test high-speed propulsion technologies, such as a turbine ramjet combined cycle engine. TSC Beijing's rapidly printed 3D components have an impact beyond any one systemthey could allow China to field more test UAVs soon, speeding up next-generation hypersonic technologies.

According to Hong Kong's "South China Morning Post (SCMP)" reported on the 17th, on the day of the upcoming National Day celebrations on the 70th anniversary of the founding of the People's Republic of China, there is the possibility of open supersonic drones. The new UAV model was identified as DR-8 or Wuzhen-8. DR-8 is the UAV model. Supersonic speed is important when the Chinese Navy encounters the combat group of US aircraft carriers in the South China Sea or the Western Pacific. The DR-8 is responsible for tracking down and navigating China's DF-21D "Carrier Killer" and DF-26 ballistic missiles. According to Zhou Chenming, a military expert in Beijing, DR-8 can reach a top speed of up to 4,000 km / h through the enemy air defense network and return with intelligence. This UAV model is fully capable of reaching the US island of Guam in the western Pacific.

BZK-008 CH-91  WZ-8The appearance of the DR-8 is quite similar to that of the American UAV D-21 that the US stopped using many years ago. The D-21 was used by the United States in Chinese reconnaissance missions and many crashed with rubble that was scattered throughout China. A relatively intact D-21 was exhibited at the Beijing Military Museum a few years ago. From November 1969 to March 1971, a total of four actual missions were flown, all against the Chinese Lop Nur test site, but all four failed. Among them, the first three successful photographs were taken, but all of them failed to recover, while the fourth time the vehicle disappeared after entering Chinas airspace. The wreckage exhibited by the China Aviation Museum was the last D-21 that went missing in 1971.

The D-21 program, although never operationally successful, left a critical legacy for other intelligence and national security programs. The D-21 drone incorporated a number of technologies that would mature in future defense and intelligence technology programs including: unmanned aerial vehicles, stealth design features, and ramjet engine technology. The D-21 drone vehicle is the reconnaissance vehicle developed and used in the TAGBOARD program. The unused vehicles were decommissioned and sent to the Military Aircraft Storage and Disposition Center in 1976, where they are visible to the public. At that time, the National Reconnaissance Office authoriz~d a very few statements which could be released in response to direct public query about the drone vehicle. These specifically declined to comment about denied area overflight missions.

BZK-008 CH-91  WZ-8In mid-2018 a satellite image appeared online. The figure showed that four different types of unmanned aircraft lined up. The right-to-left suspects are respectively light yellow painted pterosaur-2 large-scale unmanned attack aircraft, gray. The painted "Xianglong" high-altitude long-time strategic reconnaissance aircraft, a black painted mysterious multi-wave supersonic unmanned aerial vehicle that has never appeared before. On the far left, it is suspected to be a white Rainbow-3 drone with a "winged cap" (small duck wing = canard). The number is at least dozens. It may be used for unmanned cluster tactical testing. In March 2017, there were tests the "Pegasus" drone formation combat capability. This machine is a domestic model of China Rainbow-3 authorized for Pakistani production. The most mysterious of these is the black triangle unmanned aerial vehicle, which has a very flat shape and seemed to some observers to utilizes the wave-rider design to facilitate high-sonic flight at the edge of the atmosphere. It is reported that the photo was taken on 07 June 2018 at a military airport in the northwest. After a few days, other aircraft are still there, and the black aircraft disappeared, which was mysterious. Some people said that this mysterious aircraft was a "Dark Sword", but the shape is obviously different, and the aircraft had been exposed repeatedly over the years. CCTV reported the JF12 hypersonic shock wave wind tunnel was being used for tests in October 2017 with a triangle-shaped wave-body hypersonic unmanned aerial vehicle that was similar. BZK-008 CH-91  WZ-8As a rule, the contour of the cross-section of the nose portion of the fuselage of supersonic air craft has the shape of a circle. With the nose portion being of this shape, the aerodynamic center is considerably shifted when switching from the subsonic speed to the supersonic speed. This shape also brings about a decrease in the aircraft directional stability and, as a result thereof, the area of the fin has to be increased. In addition, this disturbs the united vortex system of the fuselage along with the wing.

To eliminate these difficulties, use is made of aerodynamic edges arranged along the sides of the nose portion of the fuselage from the nose to the wing (ibid.). However, the great surface of these edges decreases the maximal aerodynamic ratio of the aircraft. In order to provide for better operating conditions of the air intake ducts, with the engines disposed under the wing middle portion, a nose portion having a cross-section of a circular shape must be mounted above the wing. With the above described aircraft, the surface of friction is increased, and the boundary layer bleed of the fuselage and the wing also increases. Simultaneously, the size of the air craft along the vertical line likewise becomes greater, and this is particularly the situation at the point of disposition of the air intake ducts.

Moreover, with the air intake ducts disposed before the aircraft e.g., to provide for a higher directional stability of the aircraft, the area of the fin must be increased, thereby resulting in a greater resistance on the part of the aircraft. In addition, the weight of the aircraft increases.

Mounted in the lower portion of the fuselage is a delta wing and nacelles accomodating engines and air intake ducts are located under the middle portion of the wing. The contour of the cross section of the nose portion of the fuselage, except for its end, is essentially two arcs of different circumferences, disposed one above the other.

CASC Rainbow CH-92

CASC Rainbow CH-92The CASC Rainbow CH-92 is an improved version of the UAV CASC Rainbow CH-91. After developing the CH-91, CASC (China Aerospace Science and Technology Corporation) developed the CH-92 in the early 2010s. Presented in 2012, this drone has a fuselage with more refined and more aerodynamic lines than its predecessor. The wings are in the middle position and the tail is in "V". The engine, probably with pistons, is installed at the rear of the fuselage and drives a propeller. It is equipped with a fixed tricycle landing gear, which allows it to be operational from a runway or a stretch of road without the need for specific equipment to take off.

The CH-92 has been in production since 2014. The development and design of the multi-purpose unmanned aerial vehicle of the model was conducted by the Chinese experts in the field of aerospace technologies and aerospace engineering specifically for deployment in the military sphere. This device is a high-tech drone used to perform a wide range of various tasks, which includes the collection of reconnaissance data, patrol and observation flights, coordination of military units in the battlefields, etc. Among other things, a number of modifications of this device can also be positioned as an independent combat air Means - unmanned aircraft CASC Rainbow is equipped with missiles, which allows you to destroy ground targets.

Developed by the state-owned China Aerospace Science and Technology Corporation (CASC), the CH-92A drone has a combat radius of more than 250 kilometers, a ceiling of 5,000 meters, and a maximum speed of 200 kilometers an hour, and it can carry two missiles, including the FT-8C air-to-ground missile that can reach targets 9 kilometers away, according to publicly available information.

Serbia has reportedly taken delivery of a batch of CH-92A armed reconnaissance drones plus missiles recently, the first time China has exported military-use aviation equipment to a European country and a milestone for Chinese arms firms in the European market, analysts said on 06 July 2020. The drones are expected to become some of the most advanced weapons in the Serbian arsenal, as the cost-efficient unmanned aircraft can conduct tactical reconnaissance, precision targeting, ground attack and patrol missions.

Serbian President Aleksandar Vucic inspected the drones on 04 July 2020 local time, according to Serbia's Ministry of Defense. A total of nine CH-92A drones plus 18 FT-8C air-to-ground missiles were included in the delivery. Fifteen more drones are expected in future procurements.

Beijing-based military expert Wei Dongxu told the Global Times on 06 July 2020 that the CH-92A is the best option for Serbia because of its high cost-efficiency. At a relatively low price, this type of medium-sized drone can offer precise tactical reconnaissance, hit ground targets including high-value targets and bunkers, guide artillery fire, and conduct patrol missions in sensitive areas such as border and conflict regions. Chinese military observers pointed out that while the monetary worth of the deal is not high, this is the first time China has exported military-use aviation equipment to a European country, which will have great significance in Chinese arms firms' position in the European market.
