    Pictures released earlier this week by the Japan Maritime Self-Defense Force (JMSDF) showing mysterious unmanned aerial vehicles (UAV) hovering above and parked on the rear landing deck of a Chinese frigate at sea have left defense analysts scratching their heads.

    The pictures, first published by Japanese media on Wednesday, were taken while three People’s Liberation Army Navy vessels — the Type 054A missile frigates Zhoushan and Xuzhou, and the electronic reconnaissance and missile tracking Beijixing — conducted exercises in the West Pacific, about 700km off Japan’s Okinotori.

    A Japanese surveillance aircraft spotted the vessels on April 29 as they crossed from the East China Sea into the strait of Osumi, the first such crossing by PLAN vessels in nine years. The ships were again spotted on their return journey on Monday.

    Aside from the rare crossing in a channel usually used by the US 7th Fleet, what mystified defense enthusiasts were two pictures released by the JMSDF, one showing three unmanned helicopters on the platform of the Zhoushan and another showing a similar type of UAV hovering above the vessel.

    The People’s Liberation Army has a longstanding interest in UAV technology, and several civilian and military firms, including Aviation Industry Corp of China (AVIC), have been working on a variety of models. However, China has yet to confirm the successful development of an unmanned helicopter that is heavy enough and capable of vertical takeoff and landing (VTOL) at sea, where runways are in short supply.

    Very few models worldwide have demonstrated the capability so far. One of them, the Camcopter S-100s, built by Austrian firm Schiebel Corp, held a successful trial at sea last month on board an Italian naval ship.

    According to analysts, the UAVs seen on the Zhoushan bear a striking resemblance to the S-100. The S-100 was showcased at the Fourth China International Exhibition on Police and Anti-Terrorism Technology and Equipment Exhibition held in Beijing in April last year, and defense-related Chinese Web sites have paid close attention to the device.

    Rumors have circulated in defense circles that China may have placed orders for several S-100s. Although the EU has an arms embargo on China, the rules appear to have been relaxed in recent years, limiting exports to purely defensive platforms.

    Foreign clients of the S-100 include Germany, the United Arab Emirates, Libya and South Korea, which experienced a crash in Incheon on May 11, killing one person. Pakistan has also expressed interest in acquiring the UAV.

    Another possibility raised by some experts is that Chinese firms reverse-engineered the S-100, as they have often done with foreign technology.

    One model, China’s Sunward Tech Star-lite SVU200, which conducted its maiden flight on land recently, looks very similar to the S-100. However, Greg Waldron of Flight Global, who attended the Beijing Air Show in September, where the SVU200 was showcased, told the Taipei Times the manufacturer had not mentioned sea capabilities for the aircraft.

    Unmanned vehicles can serve a number of military purposes, including electro-optic surveillance, reconnaissance, target acquisition radar and transmission relay.

    Such capabilities substantially increase a navy’s ability to monitor and control its surroundings. Larger models can also carry a variety of missiles.

    China's Sparrow Hawk/Air Sniper UAV developed by AVIC:











    "Sparrow Hawk" Made Its Debut of Double Load Remote Sensing Flight

    2011-08-01

    Recently, “Sparrow Hawk”, UAV developed by AVIC fulfilled its first scientific test flight with high-accuracy SAR (polarimetric synthetic aperture radar) and double loading of hyperspectral optical payload.

    The test flight, which experienced four hours and thirty minutes, has resolved technical problems with VAU’s double loading remote sensing flight, and achieves high-accuracy, multi-load and one-platform remote sensing imaging.

    Very impressive!
    There's a huge export market for these birds.
    Would love to see some of them in PAF colors.

    China's AVIC stealth UAV prototype technology demonstrator


    China AVIC's prototype "baby"/demonstrator UAV. AVIC is famous as the parent company that built the J-10 Vigorous Dragon.
    The air inlet is placed on the top to shield it from ground radar. The upper fuselage follows the "continuous curvature" stealth design principle, where the radii is continuously changing as you move from the front and towards the rear.


    The angled vertical stabilizers are a telltale sign of a stealth aircraft. Also, note the saw-tooths on the wheel bay doors. The exhaust looks like a new "continuous curvature" design. The planform alignment looks good too (e.g. parallel lines formed by main leading wing and opposite trailing wing near engine exhaust).


    The planform alignment is harder to see. I highlighted it for you guys. You will also note the underside is uncluttered and stealthy.

    Chinese (SVU200) Completes Autonomous Flight Tests



    China's SVU200 unmanned helicopter has successfully completed its first flight tests.

    The helicopter's first full autonomous flight occurred on 4 September near the Chinese city of Changsha, says Dennis Fetters, owner of Fetters Aerospace. Fetters is an American rotorcraft developer who designed the SVU200 for Sunward.

    During the SVU200's first autonomous flight, the helicopter completed an auto take-off, hovered and flew sideways and backwards before landing exactly where it took off.



    On 5 September, the SVU200 transited a 2.1nm (4km) course, navigating with waypoints and landing back at its starting position. It successfully completed a 2.7nm autonomous flight shortly after.

    "This event marked a turning point in the project, where the SVU200 transformed from a large helicopter flying under "human-stabilised remote-control" to a fully self-stabilised and self-controlled GPS-navigating autonomous flying vehicle," says Fetters. The SVU200's rotor head and control system provides "super-stable" control that requires one-tenth of the computer-stabilising control inputs required by other large unmanned helicopters, he adds.



    The aircraft has two payload bays, one in the nose and one in the rear. It also has hardpoints and can haul sling loads. It can be mounted with an external payload pod or external fuel tanks.

    The SVU200 is powered by a Rotax 582 engine. Fetters says this uses a special exhaust system that enables engine power to increase from its normal 65hp (48.5kW) to 78hp. This feature allows the design to lift a maximum useful load of 200kg (441lb), or to achieve a top speed of 113kt (209km/h).
