The unmanned systems industry is currently undergoing explosive growth; as a result there is an increased demand for unmanned vehicle systems designers. Our Unmanned Aircraft Systems Design course has been created to provide engineers with the necessary skills and knowledge to design unmanned airvehicle systems. This course aims to introduce to the participants, conceptual approach and development of the complete unmanned air vehicles (UAV) design. The course consist of about 60 hours of lectures, including an overview of existing UAVs and their capabilities, covering the aspects of structures, aerodynamics, weight & balance, flight performance, stability and control, UAV systems and systems integration (propulsion, fuel, etc.) , landing gear, UAV sensors (EO/IR) and integration, design aspects of stealth, and aspects of operating & mission, as well as visit to local industry involved with UAV manufacturing. A presentation of future developments, approaches and technologies in the area of UAV will summarize the course. The course lecturers are highly experienced engineers and UAV pilots which combine practical and academic experience. It is recommended that the participants in the course will have some general background in aircraft design, so this course will enhance their know-how and capabilities in the field of UAV design.
