This paper presents a study on airworthiness of fuel system for an unmanned air vehicle. The presented contents consist of network modeling for analysis and flight test results on fuel system airworthiness. First, performance prediction of fuel system for unmanned air vehicle was achieved using software tool based on theoretical analysis and empirical data. And also flight tests were performed for verification of fuel system. The most important items are selected three things among various ones that they must be tested and evaluated as a flight test for airworthiness. Those are maximum fuel flow rate, hot weather operation and fuel jettison rate. The data are acquired using ground rig equipment and flight test with the real full-scale vehicle. The developed fuel system was satisfied and certified to meet the criterion of STANAG 4671 for type certification airworthiness.
