ACTIVE FLUTTER SUPPRESSION OF A 3D-WING: PRELIMINARY DESIGN AND ASSESSMENT PART I - PROBLEM STATEMENT & CONTROLLER DESIGN

摘要

The paper presents the problem and techniques of preliminary designing an active flutter suppressor, with reference to 3D-wings dynamically controlled through conventional trailing-edge flaps. Two aspects are essential in such a project: building the wing dynamical model and designing the controller itself. The present text makes use of standard representations in aeroelasticity and modern control theory; for the sake of clarity, explicit formulae are derived and numerical results are given for a test-case. The validity of the active-flutter-suppression concept is well recognized. The concept's performances will be discussed in Part II of this paper.
