Influence of cascade configuration on aerodynamic performance of a cascade thrust reverser

The study chose equal-thickness shaped cascade blades,with the technology of hybrid grid system,and studied the influence of inlet flow angle,transition-radius,axial space between upside and underside of vane,solidity and outlet flow angle on the mass flow and axial reverser thrust.The final computation results show:the inlet flow angle,transition-radius,axial space between upside and underside of vane play the important role in whether the fan flow inducts the cascade smoothly;the solidity affects the outlet area and diverted performance of cascade;the outlet flow angle is a key-factor of design of the cascade thrust reverser,so it gives direction to the aerodynamic performance of a cascade thrust reverser.
