“…Microburst is a type of wind shear that initially develops as the localized downdraft that suddenly descends from a cloud base. The downdraft accelerates, next spreads out in a radial direction as approaches the ground and hits the cold air near the ground, eventually flows up [1][2][3][4][5]. If it occurs with precipitation, it is called a wet microburst, otherwise, it is a dry microburst [6].…”

Microburst is an atmospheric phenomenon that poses a dangerous and unavoidable threat to flying aircraft during takeoff and landing. The dynamic response of the aircraft encountered to the microburst was studied. Research on the interaction between microburst and aircraft motion is needed to assess the effects of aerodynamic forces and momentum. Unlike recent studies using conventional integrated aerodynamic models, the multi-point loading approach allows microburst nonlinear wind loading at any point on the wing and tail combination. In this method, a general reconstruction of aerodynamic forces and moments is calculated by microburst integration with different non-uniformly distributed loads functions on each surface of the aircraft. This algorithm solves the nonlinear equations of motion of a plane with six degrees of freedom and updates the plane's dynamic parameters as input to calculate time- and space-varying microburst effects for each element. The computational complexity of this method is therefore much reduced compared to CFD analysis and at the same time the details of the flight characteristics are taken into account without simplification in the simulation, which takes about 90 seconds of simulation time. We simulate and compare the results of a new and existing micro-race modeling approach. Comparing the two models shows significant differences in flight conditions such as aircraft flight path, angle of attack and angular velocity.
