Propulsion systems in unmanned aerial vehicles (UAVs) must function reliably. Since the engines are the primary mission-critical component of a UAV, it is important to prove their reliability. This is increasingly demanded by the industry from engine manufacturers.
Sky Power GmbH, therefore, tested its SP-55 TS carburettor engine to demonstrate its endurance and reliability using high stress running profile per FAR33.
“After a test period of 150 hours, as well as another 30 run-in hours prior to testing, the SP-55 TS successfully completed the test,” Karsten Schudt, Managing Director of Sky Power GmbH, looks back on the test. Prior to starting, various objectives were defined that were to be achieved with the endurance test. These included load limit and endurance data. At the same time, the airworthiness of the engine was proven and documented by Sky Power qualifying reliability against defined FAA standards.
