2008-2018, A Decade of Cooperation Between Indonesia and Turkey in Testing Wind Tunnels for Aircraft Development of Air Crew (UAV, Unmanned Aerial Vehicle)
Turkish Aerospace Vice President for Corporate Marketing and Communication, Tamer Ozmen, and Executive Vice President for Unmanned Air Systems, Omer Yildiz, along with other management teams visited BPPT's Center for Aerodynamics, Aerolastics and Aerospace Technology (BBTA3), in the Science Research Center Knowledge and Technology (PUSPIPTEK), South Tangerang, 11 October 2018.
The collaboration between BBTA3 (Central for Aerodynamics, Aeroelastics and Aeroacustics Technology) of BPPT and Turkish Aerospace has been started since 2008 when the first campaign of wind tunnel testing was carried out at ILST (Indonesian Low Speed Tunnel) for ANKA, an MALE class aircraft (Medium Altitude Long Endurance) belongs to Turkish Aerospace.
During the visit Ozmen said that Turkish Aerospace gave high appreciation for the contribution of BPPT through BBTA3 in the development of its Unmanned Air System. Ozmen said that since 2008 BBTA3 and Turkish Aerospace have been and are collaborating on five wind tunnel testing campaigns for unmanned aircraft.
The first wind tunnel testing campaign was carried out on ANKA models with full configuration (full configuration) and 2D wing models. This testing campaign is directed to obtain aerodynamic characteristics of the first variant. This testing campaign was carried out for eight months from March to November 2008. Data collected very much during this test played a very important role both for the development of software for the autopilot control system, as well as to verify flight performance before first flying.
The second testing campaign was conducted at ILST in April-May 2015 for other ANKA variants including the SATCOM variant. Testing of scale models in this campaign was carried out to obtain the effects of wing deformation, installation of communication devices such as SAR and SATCOM radomes, EO / IR cameras, winglets and air inlets on ANKA aerodynamic characteristics.
The third wind tunnel testing campaign at ILST was carried out on the full scale ANKA-NG (Next Generation) wing in June 2015. Aerodynamic hinge moment data for 2D wings was obtained for various trailing edge deflections. This data is very important in developing a deicing system or antipation of contamination on the wing surface during the operating cycle.
The fourth wind tunnel testing campaign was carried out for ANK-NG in ILST BBTA3 in a scale model. In this test new wing geometric effects on aerodynamic forces and moments were studied for 60 valid polar data.
"The four ANKA wind tunnel testing campaigns at ILST have contributed greatly to the development of the ANKA UAV System with superior flight performance and improved safety features," said Tamer Ozmen, Turkish Aerospace Vice President for Corporate Marketing and Communication at his visit last October 11 to BBTA3 BPPT.
Ozmen said that currently ANKA is a combat-proof MALE-class UAV for Intelligence, Reconnaissance, Surveillance and Strike Systems for both internal security and maritime surveillance operations. ANKA is now ready for military missions needed with various payload configurations.
At present Turkish Aerospace continues to collaborate with BBTA3 for the fifth time in the testing of new wind tunnel UAV Systems for High Payload Capacity.
The fifth testing campaign is intended to obtain the aerodynamic characteristics of their new aircraft model, YFYK, which is scaled in full configuration. This testing campaign starts September 2018 and is planned to acquire 233 polar aerodynamic data including for various control field deflections and various payloads configurations until the end of October 2018.
Ozmen added that Turkish Aerospace was very grateful for BPPT's contribution through BBTA3 in the successful development of the UAV Turkish Aerospace product line, he hoped this collaboration would be sustainable for the future.
On this occasion, the Head of the Center for Aerodynamics, Aeroelastika and Aeroakustika Technology (BBTA3), the Agency for the Assessment
and Application of Technology (BPPT), Fadilah Hasim admitted that cooperation with Turkish Aerospace in UAV aerodynamic testing was very useful.
Fadilah said that in 2008 when BBTA3 BPPT (formerly LAGG) began cooperation in the development of the ANKA UAV with Turkish Aerospace, the aircraft crew technology had only begun to develop.
"The ANKA wind tunnel testing campaign provides an opportunity to gain experience in studying small UAV planes or aircraft with low Reynolds numbers," Fadilah said.
According to Fadilah, this aerodynamic database for low Reynolds numbers is still relatively limited compared to databases for high Reynolds numbers which are usually owned by large planes which have been widely found in books and various literature.
"But planes with small wings that are very sensitive
even to small, small disturbances, there are still not many databases. We have
the opportunity to study, "he added.
Fadilah explained that the aircraft model testing facility on BBTA3 BPPT, ILST (Indonesian Low Speed Tunnel) is a wind tunnel with a 4 m × 3 m test section built by President B.J. Habibie uses technology from Germany and the Netherlands.
"Our wind tunnel is very precise with a very low intensity of turbulence below 0.1 percent, a very thin boundary layer below 5 percent, and a very uniform flow angle," Fadilah said.
"ILST wind tunnel is a world-class wind tunnel, and we always try our best to maintain it well," he continued. (BBTA3 BPPT / Humas / HMP)

There was a notion that ANKA 2 was a cooperation between Turkey and Indonesia but that is not the case.
TAI only used the wind tunnel facilities in Indonesia to test the aerodynamics of scale models
