Key Takeaways:
Rolls-Royce has retired its Boeing 747-200 "Flying Test Bed" (FTB) after 20 years of service, completing over 2,000 hours of crucial engine development testing.
The uniquely modified aircraft, capable of operating with five engines, was instrumental in developing modern powerplants such as the Trent 1000 and Pearl 10X.
A significant milestone for the FTB was successfully testing a Trent 1000 with sustainable aviation fuel (SAF), a key step in Rolls-Royce's push for 100% SAF compatibility.
Its final mission supported the Advanced Low Emissions Combustion System (ALECSys) demonstrator, as Rolls-Royce shifts to new testing strategies including ground tests and digital modeling.
