Abstract In this paper, the effect of a 3D blade design on aerodynamic, aeroelastic and structural behavior scaled UHBR fan is investigated numerically. First, an initial sensitivity analysis for geometrical features sweep lean as well adaption thickness position in hub region conducted. Positive found to benefit total pressure ratio, while positive improves polytropic efficiency stage. Moving ...

In the small mass ratio expansion and on equatorial plane, two-body problem for point particles in general relativity admits a quasi-circular inspiral motion followed by transition-to-plunge motion. We first derive equations governing Kerr background at adiabatic, post-adiabatic post-post-adiabatic orders slow-timescale terms of self-force we highlight structure higher subleading orders. parall...
