    Turkey To Buy 10 Locally Made Anka Drones

    ANKARA — Turkey is preparing to sign a contract for 10 locally made UAV systems dubbed the Anka, procurement authorities said. They did not specify a contract price.

    Murad Bayar, Turkey’s chief procurement official, told reporters that a final round of talks for the contract involving the 10 UAVs and their ground control stations is underway. He said the contract would be signed in the next couple of months.

    This will mark Turkey’s first purchase of UAVs designed, developed and manufactured indigenously. Bayar promised the Anka would incorporate “progressive design and features.”

    Turkish Aerospace Industries (TAI), maker of the Anka, said the UAV had successfully passed acceptance tests late in January. TAI officials said the final, decisive tests on Jan. 20-21 involved a full endurance, 18-hour flight, a successful auto landing, data link performance at a distance of 200 kilometers under winds up to 45 knots, and night takeoffs and landings. The Anka has registered 140 flight hours.

    Meanwhile, procurement officials said the Turkish police force also is preparing to order the Anka, which means more funding for “fine-tuning efforts” as part of the program.

    In December, Turkey’s defense procurement agency, the Undersecretariat for Defense Industries (SSM) and Tusas Engine Industries (TEI), a private company, signed an agreement under which the company will develop and produce engines for the Anka.

    The protocol was signed at the main office of the agency in Ankara. SSM Chairman Murad Bayar said at the ceremony that building the engine was even more difficult than building the aircraft. However, TEI General Manager Akn Duman said the body had enough infrastructure for the project.

    Anka is a medium-altitude long-endurance (MALE) vehicle; such UAVs usually operate for 24 hours at an altitude of 10,000 feet.

    Anka, meaning Phoenix in English, is the first MALE-type UAV to be produced by TAI. Several prototypes have been produced with other engines. One of the prototypes crashed during a test flight in September but several other flight tests have been carried out successfully.

    A version called Anka+ calls for an armed vehicle, using a rocket attached to its body and sensors.

  • Turkey prepares to manufacture new type of UAV

    Turkey prepares to manufacture new type of UAV

    The Turkish Scientific and Research Centre for Aerospace Technologies (UZAYTEM) jointly with Tusaş Motor Sanayi are preparing to manufacture a new type of unmanned aerial vehicle (UAV), the Anadolu Agency reported on Tuesday.

    The new UAV will differ from earlier manufactured UAVs in regards to functionality.

    The new UAV will have a length of six meters and a total weight of 150 kilograms. The first test of the new model of the UAV will be held in August of 2013. If the new UAV is successful, the Tusaş Company will begin mass production by 2014.

    This will be the third Turkish UAV.

    Turkey has been working to create its first reconnaissance UAV since 2004. About 180 engineers have been involved in the project which refers to medium class vehicles with a long flight span.

    ANKA has several advantages in comparison to the Israeli UAV Heron. The Heron can lift no more than 185 kilograms of payload to the height of 30,000 feet, while this figure exceeds 200 kilograms in the ANKA UAV.

    In recent years, the Turkish military-industrial company has focused on manufacturing domestic defence products.

    At present, Turkey conducts work to manufacture the UAV Simsek (“Lightning”).

    Its length is 2.3 meters, with a wingspan of 1.5 meters. The maximum takeoff weight is 75 kilograms, with a speed of 740 kilometers per hour.

  • First piloted aircraft just on fuel cells takes off

    First piloted aircraft just on fuel cells takes off

    a8Fuel Cells, July  21  2009 (The Hydrogen Journal)

    In another first for Hamburg’s hydrogen fuel cell industry, the first piloted aircraft able to take off just using fuel cell power, has been demonstrated at Hamburg airport on July 7 2009.

     

     

    The aircraft, Antares DLR-H2, was developed by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR).

     

    The propulsion system was developed by DLR Institute for Technical Thermodynamics (Institut für Technische Thermodynamik – Stuttgart) in collaboration with its project partners, Lange Aviation, BASF Fuel Cells and Serenergy (Denmark)

     

    To date, fuel cells have been tested on aircraft to provide auxiliary power (eg cabin lighting), and they have been used to fly unmmaned aerial vehicles (UAVs), but this is the first manned aircraft just using fuel cell power for main propulsion and take-off.

     

    “We have improved the performance capabilities and efficiency of the fuel cell to such an extent that a piloted aircraft is now able to take off using it,” stated Prof. Dr-Ing Johann-Dietrich Wörner, Chairman of the Executive Board at DLR.

     

    The aircraft has a wing span of 20m, and was constructed by Lange Aviation. It has a cruising range of 750km, or flying time of 5 hours.

     

    The fuel cell is hung under the left wing and the hydrogen tank under the right wing – the hydrogen tank has a capacity of either 2 or 4.9kg.

     

    The total additional weight under the aircraft wings is 100kg – the wings had to be made out of new materials to ensure that it could be safely carried.

     

    The aircraft can fly at up to 300 km/h without any wing flutter, although the current propulsion system only allows 170 km/h speeds.

     

    The fuel cell can provide 25 kW of electrical power, but only needs 10kW to fly in a straight line.

     

    The total efficiency from tank to powertrain (including propeller) is around 44 per cent, compared to 18 to 25 per cent for systems powered by kerosene or diesel.

     

    The fuel cell was developed by DLR Institute for Technical Thermodynamics in collaboration with BASF Fuel Cells (electrolytic membrane and catalysts) and Serenergy A/S (stack subsystem).

     

    In the future, DLR hopes to improve efficiency, extend service life, and optimise cooling systems, fuel cell architecture and components. “”At this stage, we have only tapped into a fraction of the performance capabilities of this technology for aerospace applications,” says Project Manager Dr-Ing. Josef Kallo.

     

    DLR is aiming to demonstrate that fuel cells could be a reliable source of on-board power for commercial aircraft.
