What is impressive is that 28 hours is endurance with the said load of 12 missiles. Completely clean, that UAV was tested to 49 hours of endurance.
They are achieving this with prototype air-frame. The serial production airframe is supposedly lighter and said to increase ISR "clean" configuration endurance to 55 hours.
AKSUNGUR Carved Its Name into the Skies in 2020 - TAI MAGAZINE | #118
AKSUNGUR, the newest and most assertive member of the Unmanned Aerial Vehicle (UAV) ANKA, made a memorable impression with its achievements in 2020. The aerial vehicle, which has a high payload capacity, has performed two record-breaking flights showcasing its striking performance in intelligence, surveillance, reconnaissance, and attack tasks, and its capabilities for long-term operations up to 40,000 feet.
The strongest in the ANKA family
Always striving to present its users with stronger, more qualified, and safer products, Turkish Aerospace, in August 2017, started working on the design and manufacture of an aerial vehicle which can stay in the air for a longer period of time and carry more payload. Considering the achievements of ANKA, the new aerial vehicle would meet the changing needs of users based on advancing technologies. Led by Turkish Aerospace UAV Systems Executive Vice President Dr. Ömer Yıldız, the operations were planned to be completed in a short period of 17 months. Built on ANKA’s current avionic architecture and software capabilities, the new aerial vehicle’s conceptual design process was the first phase to be completed. In February 2018, the company completed the preliminary design process and held the Critical Design Meeting for the vehicle a few months later
Borrowing its software and equipment from the ANKA series, AKSUNGUR was designed with a new wing platform to carry more payload than its product family. The company designed the new unmanned aerial vehicle’s wing platform using the wetlaid process and rule of thumb instead of resinimpregnated composite materials called pre-preg composite fibers and proved once again that it’s one of the few companies in the world which can manufacture wetlaid wing composites in similar sizes. Throughout the process, the company centralized the product and program management and rolled out its new UAV named "AKSUNGUR" in January 2019. A medium-altitude, long-endurance unmanned aerial vehicle with EO/IR, SAR, and SIGINT payloads and various air-toground weapons, AKSUNGUR performed its first flight on March 20, 2019 and made its family very proud. The aerial vehicle managed to stay in the air for 4 hours and 20 minutes during its first flight.
Two record-breaking flights in 2020
With newly designed features such as guidance control system, structurals, flight mechanics, landing gear, and an engine and fuel system that are different from ANKA, AKSUNGUR was a source of great excitement when it stayed in the air nearly 28 hours for the first time with full ammunition. Having cemented its success with a 49-hour flight, the unmanned aerial vehicle performed a flight, which was controlled from Turkish Aerospace facilities, with 12 MAM-Ls. Additionally, it also performed its first shooting drill with the TEBER guidance kit for ammunition developed by Roketsan during a 49-hour flight. During this flight at 20,000 feet, AKSUNGUR followed a route in the shape of a crescent and a star to draw our country’s flag in the skies.
The test flight, performed by four test pilots and three flight test engineers from Turkish Aerospace, was executed thanks to the efforts of a big team comprising the departments of operations, quality, and support, and the designers. Just like in previous tests, during this flight, the AKSUNGUR model's performance measured up to test data.
AKSUNGUR, which has high autonomous capabilities, performed the flight in a favorable environment and in isolation. All data was tracked and collected under the management of assigned test pilots (in periods of eighthour shifts) and flight test engineers in coordination with the Flight Test Management Center including design engineers from various disciplines. Thanks to the efforts of Turkish Aerospace teams, which didn’t encounter any negative data, AKSUNGUR succeeded in standing out among its peers with its low-cost, long-endurance payload carrying capabilities.
The unmanned aerial vehicle, which led to numerous moments of pride by staying in the air for 49 hours in its 59th flight, has completed a total of 300 flight hours. The vehicle, whose model was first exhibited at the Paris Airshow and the 1/1 scale of which was first displayed at the International Defence Industry Fair (IDEF), will be equipped with a special fuselage in the second phase.
The company aims to take this improved version of AKSUNGUR into the skies soon and to make sure its stays in the air for 55 hours.
