As a follow-on to our most popular auxiliary power unit (APU), the 131-9 APU, we developed the HGT750 to meet the needs of the COMAC C919 and Irkut MC-21 aircraft. This APU adheres to the latest certification standards while delivering world-class fuel efficiency. It features variable-speed capability while using a lower weight starter/generator.
Additionally, the HGT750 features the lowest emission standards in the industry, utilizing our innovative combustor system which provides 25% lower emissions. The HGT750[C] APU for the COMAC C919 will deliver industry-leading reliability of more than 10,000 hours between unscheduled APU removals and the lowest fuel burn available in its class. This remarkable reliability and efficiency can lower the cost of operations for a C919 aircraft by more than $20,000 a year.
