Rolls-Royce has completed the flight-test campaign for the Pearl 10X turbofan it is developing for the in-development Dassault Falcon 10X business jet. Over the past six months, the powerplant has been evaluated on the engine maker’s Boeing 747 testbed aircraft, logging around 36,000 nm during the course of more than 25 flights conducted in the U.S.
During the tests, the engine was operated at a maximum altitude of 45,000 feet, with the testbed achieving a maximum speed of Mach 0.90. According to Rolls-Royce, the test campaign achieved all of its objectives and gave the company confidence in the maturity of the program as it continues to work with Dassault on the 10X program.
"On behalf of Rolls-Royce, I would like to extend my heartfelt thanks to our incredible global engineering and experimental test teams for their outstanding dedication and expertise in successfully completing the Pearl 10X flying testbed campaign,” said Rolls-Royce Deutschland senior v-p Philipp Zeller. “This achievement is a testament to your commitment, innovation, and global collaboration and I am immensely proud of everything we have accomplished together."
