TEKNOFEST Istanbul Aviation, Space and Technology Festival (TEKNOFEST 2019), which has become one of the most important technology meetings in Turkey, has started to appear in competitions as the countdown continues.

Turkish Aerospace Industry Inc. (TUSAŞ)-trainee engineers working at Uludag University R & D Center in Bursa developed the Cevheri UAV for the TEKNOFEST 2019 Combat Drone (UAV) competition to be held next month.

R & D Center Director Prof. Dr. Kemal Fidanboylu’s mentorship and Bursa Uludag University Mechanical Engineering Department Vice President Prof. Dr. The team was mentored by Necmettin Kaya and included 23 students from the Department of Electrical and Electronics Engineering, Industrial Engineering and Mechanical Engineering.

It was decided that young engineers who could take a role in the aviation and defense industry of Turkey should participate in the fighting UAV competition in order to develop, train and evaluate the work done within the scope of the project, which is intended to give them competence.

The Cevheri UAV team, which has been carrying out its work in Ulutek Teknopark since January, received support from 20 sponsors and Bursa Uludag and Bursa technical universities in the process.

As part of the project, The Engineer candidates undertook tasks such as the production of Cevheri, flight control, and algorithm, autonomous deadlock.

After preliminary design and analysis, production of the UAV was carried out. With a wingspan of 2.4 meters and a length of 1.8 meters, Cevheri’s maximum takeoff weight corresponds to 9.5 kilograms.

With its fixed landing gear, composite fuselage and lightweight skeleton structure, Cevheri embodies a high-end structure for model aircraft. The UAV made its first flight at Bursa Yunuseli Airport after successfully passing ground tests and simulations held prior to the flight. The team, which collected the required data on the first day of the flight, is continuing optimization work on the aircraft.

Cevheri completed tasks such as ground station communication and image transfer, control and modification of aircraft parameters in ground control station software, domination of all parameters required for manual flight and autonomous flight and realisation of flight with fully original software, crash to target aircraft performed with the graphics development card in the UAV and managing the power systems required for transferring power to the engine.

Cevheri’s capabilities

The vehicle successfully performs stable flight with a wide wingspan and aerodynamically flawless air contact surfaces. Physically compared to the model aircraft, it has effective maneuverability of 15 meters with its ultra-strong engine and flawless moving surfaces.

With its high capacity batteries, it is capable of handling 40 minutes and approximately 38 kilometers of uninterrupted high-performance flight conditions with a service altitude of 3,500 feet.

The vehicle also transfers location and various sensor data (pitot-static sensor, IMU, integrated GPS, motion, temperature, pressure sensors, etc.) of the aircraft to the ground station quite quickly with the GPS and fast data transfer radio located on it.

Cevheri’s capabilities include autonomous flight and crash capability. The vehicle can be locked by detecting the rival aircraft through the image taken with the high-speed video card.
