Abstract
Microburst wind shear is very dangerous and threatening for aircraft in low altitude flight, which makes aircraft uncontrollable and also difficult ‎in forecasting and detection. This is consequential research in order to make the aircraft controllable when encountering the phenomenon. Most ‎studies‏ ‏have simulated aircraft encountering the microburst by applying single body model. This model, consider location of microburst on the ‎aircraft center of gravity, where microburst must be applied all through fuselage, wing and tail combination. For more realistic simulation, ‎microburst should be applied to more points of aircraft body in addition to C.G., which is known as developed multi-body model. Applying the ‎influence of wind gradients to aircraft body is the advantage of this model. In this paper, results of both single and multi-body was conducted and ‎compared. In comparison of single body model with existing methods in references, has provided a proper consistency with the tolerance of 10%. ‎Considerable results have shown in comparison of single-body and multi-body model in accordance to flight trajectory response, heading angle ‎and pitching moment to wind shear model and the ability of the multi-body model for modeling of aircraft realistic flight encountering microburst ‎has been proved.‎
