In order to study the influence of the new thrust reverser device on the aerodynamic performance of the blended-wing-body distributed propulsion system

the fuselage was simplified into a two-dimensional airfoil

the numerical simulation method was used to study the angle of attack

the openness of the thrust reverser and the effect of the fan on/off on the flight parameters. Some suggestions about the design of the thrust reverser device on the blended-wing-body distributed propulsion system were carried out. The results show that when the thrust reverser and the fan are turned on

the lift coefficient and pitch moment coefficient of the model increase greatly; as the openness of thrust reverser increases

the lift coefficient and the pitching moment coefficient also increase; the attack angle of incoming flow also has a large impact on the aerodynamic performance of the blended-wing-body distributed propulsion system.
