(corrects companies that shipped a first propulsor)
Engine Alliance partners GE and Pratt & Whitney have concluded delivery of a spare "propulsor" to Airbus A380 operator Emirates.
A propulsor features all the engines components with the exception of the fan. Essentially operators use a spare propulsor attached to fan while another propulsor is being repaired.
The shipment to Emirates is the first by both P&W and Engine Alliance of a propulsor rather than a full engine.
"The fan module has a very long life, so it can be reused with a new propulsor to provide a full spare engine," explains EA chief engineer Paul Smith.
Having a propulsor rather than a full spare engine with a fan attached creates cost savings in spares management. The smaller propulsor is also capable of being transported on most widebody freighter aircraft, giving the customer "great transportation flexibility", says Engine Alliance.
Emirates placed the first GP7200 into service in August 2008 when it launched A380 operations. Engine Alliance says no in-flight shutdowns have occurred, and the engine has achieved a departure reliability rate of more than 99.9%.
Air France, Korean Airlines and International Lease Finance Corporation are also GP7200 customers, with delivery of the first engine to Air France scheduled for October.
The GP7200 is based on the GE90 and PW4000.
