These models were delivered to Systems Technology Inc from the University of Minnesota under a different contract. The focus for this study is on the rigid body dynamics which are in the lower frequency range. This vehicle has high coupling between rigid body and flexible dynamics so traditional classic rigid body modes do not exist. Regardless, the low speed models do exhibit some behavior familiar to traditional aircraft dynamic modes (e.g., short period, phugoid, dutch roll, roll subsidence, spiral).enRigid Body DynamicsFlexible Body DynamicsWorking Paper
