Abstract

In this paper, behavior of the aircraft with flexible wing in dealing with atmospheric disturbances has been modeled and analyzed. In this research, material of wing is metal and wing has been modeled as a thin-walled (wing box), as well as wing mass distribution, shape modes and frequency is calculated by lumped mass and assumed mode shape method. For analyzing the effect of aircraft mass on the vehicle behavior, four models with different mass are simulated until critical condition is determined. Atmospheric disturbance is a undesirable input to aircraft dynamic where decrease flight safety therefore, the effect of this phenomena are analyzed as a random input on aircraft behavior. The using model for atmospheric disturbance is Monte Carlo model where the method of MODELING is submitted. The effect of this disturbance has been simulated in two conditions. In the first simulation, intensity of turbulence is 100 ft/sec and intensity of the second simulation is 400 ft/sec until the turbulence that makes instability is assigned.
