The fan system was tested on Trent 1000 ALPS (Advanced Low Pressure System Technology) engine, and then the flight test will be carried out on rolls royce 747 test platform in Tucson, Arizona.
Mark Thomas, chief engineer of rolls royce large civil engine business technology and future project, said, "We have taken another step forward in the verification process of CTi fan system technology of Advance and UltraFan engine structures. The successful completion of the test under crosswind flight conditions proves the design performance of the new fan and pushes the project to a new stage including flight test. "
CTi fan system includes carbon/titanium alloy fan blades and composite casing, which can reduce the weight of each plane, which is equivalent to carrying seven more passengers without increasing the cost.
The fuel consumption and carbon dioxide emissions of the Advance engine are reduced by at least 20% compared with the first generation Trent engine, and it is expected to be put into service in 2020.
UltraFan is a gear design with variable pitch fan system. The technology adopted is expected to be put into use in 2025, and the fuel consumption and emissions will be reduced by at least 25% compared with the first generation Trent engine. (Zheng Jinwu)
