Aeroelastic Response of Aircraft Wings to External Store Separation Using Flexible Multibody Dynamics

In aviation, using external stores under the wings is a common method of carrying payload or fuel. some cases, can be rigidly attached to wing. However, must often ejected during flight for aircraft, such as military type, which carry drop tanks and missiles. This may cause wing respond dynamically with increasing amplitudes, due impulsive load ejection change total mass. especially critical in aircraft highly flexible wings, those high aspect ratios. this case, it crucial evaluate response store separation, requires suitable simulation environment that able support nonlinear multidisciplinary analysis. To address need, work presents use multibody dynamics separation. demonstrate, compliant was selected rigid body mounted on represent an store. The time marching before after separation presented show features benefits method.
