Special Issue Information

Dear Colleagues,

Modern commercial transport aircraft relies on complex aerodynamic mechanisms and sophisticated flight control systems to achieve and maintain optimal flight performance at different flight regimes. Typically deployed hydraulically or with servos, aircraft high-lift devices, for instance, consist of moveable mechanical assemblies which are highly optimized to increase the amount of lift produced by the wing during take-off and landing. The design of such complex systems typically starts from the kinematic synthesis of the mechanisms and the preliminary design of the actuation architecture in a multidisciplinary and multiobjective context involving aerodynamic, system, and structural design.

This Special Issue on “Aerospace Mechanisms and Actuation” aims to provide a premier international platform for a wide range of professions, including researchers, academicians, and industry experts to discuss the latest advances in aerospace mechanisms, spanning from rigid-body linkages to flexible compliant members, and major achievements in the related research on both discrete and distributed actuation architectures. Focus will also be given to the evolution of actuation in aerospace by including full electrical drives for safety-critical commercial and military aircraft, helicopters, and space applications.

This work proposes a systematic topology optimization approach for simultaneously designing the morphing functionality and actuation in three-dimensional wing structures. The actuation was modeled by a linear-strain-based expansion in the actuation material. A three-phase material model was employed to represent structural and actuating materials and voids. To ensure both structural stiffness with respect to aerodynamic loading and morphing capabilities, the optimization problem was formulated to minimize structural compliance, while the morphing functionality was enforced by constraining a morphing error between the actual and target wing shape. Moreover, a feature-mapping approach was utilized to constrain and simplify the actuator geometries. A trailing edge wing section was designed to validate the proposed optimization approach. Numerical results demonstrated that three-dimensional optimized wing sections utilize a more advanced structural layout to enhance structural performance while keeping the morphing functionality better than two-dimensional wing ribs. The work presents the first step towards the systematic design of three-dimensional morphing wing sections. Full article

Abstract: Weight-on-Wheels (WoW) systems are aimed at indicating if the aircraft weight is loading on the landing gear and its wheels, even partially. That info simply reveals if the vehicle is in flight or on the ground. In this way, several kinds of accident may be prevented, for instance relating to the incorrect deployment of the undercarriage, or even to some kind of manoeuvres at a certain extent, therefore protecting the aircraft from dangerous damage. In general, it can be stated that such an intelligent sensor network may be seen as a fundamental support for the proper landing gear deployment. There are different architectures that have been proposed in bibliography, some of them based on strain gauges deployed on the structure, or on proximity sensors installed on the wheels. Being this device considered critical of safety, it is convenient to couple it with compli-mentary measurements, recorded and processed by different sources.
