The propulsion system of an unmanned aerial vehicle (UAV) provides thrust for flight and delivers shaft power to onboard accessories. During the aircraft development process, both aircraft-level airworthiness certification and engine manufacturer’s evaluations are essential to ensure flight safety. The engine manufacturer reviews the installation design parameters and may issue an official statement or a separate Flight Clearance when necessary. This paper summarizes the ground integration test and evaluation conducted from the engine manufacturer’s perspective to support the issuance of Flight Clearance. Except for the verification of electromagnetic interference (EMI) between the engine control unit and other onboard avionics which is to be performed at the aircraft level, the major test results obtained from the air vehicle were consistent with analysis data and engine rig test data, confirming compliance with all key requirements specified by the engine manufacturer. These results indicate that no significant technical issues are expected during the subsequent Flight Clearance issuance, ground taxi, and flight test phases. The findings obtained under the ground-static condition will be further refined and validated through taxi and flight test.
