ITB high altitude long endurance UAV development: Past and future

The difficulty of monitoring regional border areas, disaster mitigation areas, or foreign areas related to the operation of UAVs has become a complex issue in relation to the wide surface area coverage and identification of areas with high accuracy, demands for advanced air vehicle technology that are reliable, fully self-reliant and capable of high flight altitude and long flight time (High Altitude Long Endurance). From an economic perspective, the development of HALE will have some impacts and benefits, such as: promote the development of the domestic aerospace industry's national independence in the defense and security sector. A high altitude long endurance (HALE) UAV is currently being developed at Bandung Institute of Technology. ITB HALE UAV is designed to fly at an altitude of 50,000 to 65,000 feet and stay at that altitude for more than 24 hours. The design and development of ITB HALE UAV implement “minimum energy usage” concept, considering the combination of several areas of expertise: high aerodynamic efficiency, high motor-prop efficiency, hybrid battery-solar panel energy sources, light weight structures, efficient control, and optimum flight mission. Throughout 2016-2018, four prototypes have been made with various mission and purpose in the grand scheme of HALE ITB development. More developments and prototypes are planned until 2022 as platform for further optimization, testing, and aircraft type certification to be used by the user such as the Indonesian Armed Force.
