The development of a nonlinear simulation environment for an uninhabited air vehicle with a flexible airframe is presented. Simple, yet efficient testing procedures are employed to estimate the physical properties of the aircraft. The aerodynamic forces and moments are obtained using a doublet lattice method. The interaction between structural dynamics and aerodynamics is given special attention from...
The design of the airframe of an aircraft is constrained due to aeroelastic effects (generally related to the wings) that induce flexible modes on the structure, and may lead to structural instability. This paper addresses the problem of active mode stabilization in an aircraft with flexible wings. The main objective of closed-loop control is to enlarge the allowable flight envelope by stabilizing...
