Testing on the Safran Power Units (SPU) SPU300[BA] auxiliary power unit built for the Bombardier Global 7000 is progressing as expected towards certification by year-end, SPU said.
The SPU300[BA] recently completed electromagnetic interference testing, "effectively concluding the certification test campaign" needed for FAA approval. Earlier tests included tailcone compatibility, containment and altitude starting/operation and a 150-hour endurance test. SPU's test program involves seven APU and two prototype tailcones.
Separately, the APU also has accumulated more than 1,300 operating hours and more than 1,000 starts across four flight-test Global 7000s. Safran said the APU has demonstrated reliable starting up to FL450, and provides electrical power up to 60 kVA at FL450 and 40 kVA up to FL510.
Certifications sought include FAA technical standard order (TSO) requirements and ETOPS. "FAA certification is expected by the end of 2017," the supplier said.
The SPU300[BA] is one of two business-jet APUs that Safran, a long-time military propulsion supplier, is developing as part of its push into business aviation. The other, the SPU150[DA], is part of the Dassault Falcon 5X platform.
