Abstract

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, Ahead of Print.
Hot-to-cold transformation is essential to achieve the desired aerodynamic performance in highly loaded fan rotors. However, due to the hot geometry changes resulting from variations in blade loads, the aerodynamic performance during operation will still ...
