The Center for Aerodynamics and Aerospace Technology (BBTA3) - @bppt_ri, since early January 2021 has conducted wind tunnel testing to support the BPPT Flagship program in the field of defense and security technology, namely the innovative aerodynamic testing technology for the Medium Altitude Aircraft Model (PUNA). Long Endurance (MALE) Combatant.
This testing activity was initiated by a request for a wind tunnel test from the Defense and Security Industry Technology Center (PTIPK-BPPT) @hankambppt representing the MALE consortium to complete and confirm and add to the development of a data base for previous test results that were deemed incomplete.
This 1: 5.5 scale full MALE model test is divided into performance, stability, and ventral fin addition studies and 160 new veetail studies. This testing activity uses the Full Black Eagle MALE model (EH-20 with the latest configuration made by BBTA3 using the 2020 BPPT DIPA budget.
Given that PUNA MALE Elang Hitam (EH) -1 'will be carried out in the first flight test in 2021, but it still requires data on hinge moment measurement results from several control plane deflection angles such as Flap, Aileron, and Ruddervator, then hinge moment testing by using the 1: 3.5 scale isolated Half wing model and the 1: 2 scale Isolated Tail model made this year.
It is important to do this as soon as possible in order to complete the wind tunnel test result data which will be used to validate the design results as well as support the piloting of the aircraft. MALE Eagle-1 'in 2021.
