Morphing aeronautical systems may be used for a number of aims, ranging from improving performance in specific flight conditions, to keeping the optimal efficiency over a certain parameters domain instead of confining it to a single point, extending the flight envelope, and so on. An almost trivial statement is that traditional skeleton architectures cannot be held as a structure modified from being rigid to deformable. That passage is not simple, as a structure that is able to be modified shall be designed and constructed to face those new requirements. What is not marginal, is that the new configurations can lead to some peculiar problems for both the morphing and the standard, supporting, elements. In their own nature, in fact, adaptive systems are designed to contain all the parts within the original geometry, without any “external adjoint”, such as nacelles or others. Stress and strain distribution may vary a lot with respect to usual structures and some particular modifications are required. Sometimes, it happens that the structural behavior does not match with the common experience and some specific adjustment shall be done to overcome the problem. What is reported in this paper is a study concerning the adaptation of the structural architecture, used to host a winglet morphing system, to make it accomplish the original requirements, i.e., allow the deformation values to be under the safety threshold. When facing that problem, an uncommon behavior of the finite element (FE) solver has been met: the safety factors appear to be tremendously dependent on the mesh size, so as to raise serious questions about the actual expected value, relevant for the most severe load conditions. On the other side, such singularities are more and more confined into single points (or single lines), as the mesh refines, so to evidence somehow the numerical effect behind those results. On the other side, standard engineering local methods to reduce the abovementioned strain peaks seem to work very well in re-distributing the stress and strain excesses to the whole system domain. The work does not intend to give an answer to the presented problem, being instead focused on describing its possible causes and its evident effects. Further work is necessary to detect the original source of such inconsistencies, and propose and test operative solutions. That will be the subject of the next steps of the ongoing research.

The work at hand focuses on the modeling, prototyping, and experimental functionality test of a smart actuator based on shape memory polymer technology. Particular attention is paid to the specific modeling approach, here conceived as an effective predictive scheme, quick and, at the same time, able to face those nonlinearity aspects, strictly related to the large displacements shape memory polymers usually undergo. Shape memory polymer composites (SMPCs) may play a critical role for many applications, ranging from self-repairing systems to deployable structures (e.g., solar sails, antennas) and functional subcomponents (e.g., pliers, transporters of small objects). For all these applications, it is very important to have an effective tool that may drive the designers during the preliminary definition of the main parameters of the actuation system. For the present work, a SMPC plate sample has been conceived and realized in view of aerospace applications. An external fibre optic sensor has been then fixed with special adhesive. The temperatures needed for the activation of the Shape Memory Polymer (SMP) and strain storing have been provided by a thermo-gun and complete load–unload cycles, including strain storing, have been performed. Experimental displacements and strains have been used to validate a dedicated predictive theoretical approach, suited for laminates integrated with SMP layers.

Within the framework of the Clean Sky-JTI (Joint Technology Initiative) project, the design and technological demonstration of a novel wing flap architecture were addressed. Research activities were carried out to substantiate the feasibility of morphing concepts enabling flap camber variation in compliance with the demanding safety requirements applicable to the next generation green regional aircraft. The driving motivation for the investigation on such a technology was found in the opportunity to replace a conventional double slotted flap with a single slotted camber-morphing flap assuring similar high lift performances—in terms of maximum attainable lift coefficient and stall angle—while lowering emitted noise and system complexity. The actuation and control logics aimed at preserving prescribed geometries of the device under variable load conditions are numerically and experimentally investigated with reference to an ‘iron-bird’ demonstrator. The actuation concept is based on load-bearing actuators acting on morphing ribs, directly and individually. The adopted un-shafted distributed electromechanical system arrangement uses brushless actuators, each rated for the torque of a single adaptive rib of the morphing structure. An encoder-based distributed sensor system generates the information for appropriate control-loop and, at the same time, monitors possible failures in the actuation mechanism. Further activities were then discussed in order to increase the TRL (Technology Readiness Level) of the validated architecture.

The work at hand focuses on an adaptive system aimed at improving the soundproof performance of car door seals at specific regimes (cruise), without interfering with the conventional opening and closing operations. The idea addresses the necessity of increasing seal effectiveness, jeopardized by aerodynamic actions that strengthen as the speed increases, generating a growing pressure difference between the internal and the external field in the direction of opening the door, and then deteriorating the acoustic insulation. An original expansion mechanism driven by a shape memory alloy (SMA) wire was integrated within the seal cavity to reduce that effect. The smart material was activated (heated) by using the Joule effect; its compactness contributed to the realization of a highly-integrable and modular system (expanding cells). In this paper, the system development process is described together with the verification and validation activity, aimed at proving the functionality of the realized device. Starting from industrial requirements, a suitable solution was identified by considering the basic phenomenon principle and the allowable design parameters. The envisaged system was designed and its executive digital mock-up (CAD, computer-aided design) was released. Prototyping and laboratory tests showed the reliability of the developed numerical models and validated the associated predictions. Finally, the system was integrated within the reference car. To demonstrate the insulation effect, the experimental campaign was carried out in an anechoic room, achieving significant results on the concept value.

The idea addresses the necessity of increasing the seal effectiveness, jeopardized by aerodynamic actions more and more important as the speed increase, generating a pressure difference between the internal and the external filed, in the direction of opening the door. To recover this effect, an expanding mechanism was integrated within the seal cavity, driven by an SMA actuator.

In this paper, the development process is described together with the verification activity, aimed at proving the functionality of the realized device. Starting from the industrial requirements, the most appropriate solution was identified highlighting the working principle and the main design parameters involved. Then, the envisaged system was designed and its executive digital mock up (CAD) was released. Prototyping and laboratory validation showed the reliability of the numerical models and the associated predictions. On this basis, the integration task within the actual reference car was faced.

In the work at hand, a shape memory alloy (SMA)-based system is presented. The system, conceived for releasing environmental sensors from ground or small unmanned aerial vehicles, UAV (often named UAS, unmanned aerial system), is made of a door, integrated into the bottom of the fuselage, a device distributor, operated by a couple of antagonistic SMA springs, and a kinematic chain, to synchronize the deployment operation with the system movement. On the basis of the specifications (weight, available space, energy supply, sensors size, etc.), the system design was addressed. After having identified the main system characteristics, a representative mock-up was manufactured, featuring the bottom part of the reference fuselage. Functionality tests were performed to prove the system capability to release the sensors; a detailed characterization was finally carried out, mainly finalized at correlating the kinematic chain displacement with the SMA spring temperature and the supplied electrical power. A comparison between theoretical predictions and experimental outcomes showed good agreement.

Shape memory alloys materials, SMA, offer several advantages that designers can rely on such as the possibility of transmitting large forces and deformations, compactness, and the intrinsic capability to absorb loads. Their use as monolithic actuators, moreover, can lead to potential simplifications of the system, through a reduction of number of parts and the removal of many free play gaps among mechanics. For these reasons, technological aerospace research is focusing on this kind of technology more and more, even though fatigue life, performance degradation, and other issues are still open. In the work at hand, landing gear for unmanned aerial vehicles, UAV, is presented, integrated with shape memory alloys springs as actuation devices. A conceptual prototype has been realized to verify the system ability in satisfying specs, in terms of deployment and retraction capability. Starting from the proposed device working principle and the main design parameters identification, the design phase is faced, setting those parameters to meet weight, deployment angle, energy consumption, and available room requirements. Then, system modeling and performance prediction is performed and finally a correlation between numerical and experimental results is presented.

An original Monito-Ring system based on chirped fiber optic and draw tower grating array is presented. The target of this research activity is the realization of a device able to measure deformations of morphing structures which may show large, global displacements due to nonstandard architectures and materials adopted. The occurring strain field results, in turns, much more than the standard sensors can handle. Modulations are then necessary to keep the measured strain low. The proposed solution was conceived to overcome this limitation assuring a suitable reduction of the revealed strain. The concept is made of a flexible ring pinned on a certain number of points to the structural component of interest. The fiber optic is integrated within the ring, and depending on the angular position of the sensor, the ratio between the diameter elongation (i.e. structural strain) and the measured deformation (strain) can be almost arbitrarily set in a large range of values. From each spectrum provided by draw tower grating array, the corresponding unknown strain field is retrieved by applying an inverse technique obtaining an accurate continuous strain map. This article deals with a proof of concept analytical study first and then numerical and experimental validation.

One of the most common applications of the acoustic antennas is the detection and the localization of sources. The geometric distribution of the sensors is not the only parameter that influences the measure; also the electromechanical features of the microphones play an important role, strongly affecting the delay of the signals. For this reason, a dedicated calibration process, considering both the geometric location of the sensors and their intrinsic features, can increase the accuracy level of the measure. In this paper at hand, a dedicated calibration method is proposed, providing a global measure of the locations, comprehensive of all the above mentioned causes of delay. The acoustic signals detected by the sensors are used to determine their distances from a reference microphone; on this basis, through a triangulation method, their locations are computed. First, the calibration method was tuned in a simulation environment: the effect of the location of sound sources and reference microphone was investigated using a dedicated numerical model to theoretically predict signal produced by each microphone. A dedicated optimization process was adopted to identify layout configuration guaranteeing the right calibration also for large size antenna compatibly with anechoic room available space constraint. The proposed solution was experimentally tested on a linear shape acoustic antenna.

In this work, a design strategy is presented, addressed to adaptive structural systems, driven by shape memory alloy actuators. The peculiar behaviour of shape memory alloy materials, non-linear and fully dependent on three parameters (stress, strain and temperature), and the load path itself complicate the numerical simulation process. This is even more evident if those active elements are integrated within complex structures. Actuators generate forces. Integrated shape memory alloy–based structural actuator capability is strongly influenced by the hosting structure stiffness. It does in turn depend on the geometrical configuration. The structural architecture may be then said to modulate the performance of the aforementioned devices. The layout modifies in fact the structural resistance that opposes the action of a generic shape memory alloy actuator, even if the same topological point is referred to. This opposition affects the change of phase process (martensite ↔ austenite) regulating shape memory alloy peculiar phenomena and then impacts its performance. For simple, linear shape memory alloy actuators, the structure may be represented as an oriented spring where all the information of the parent structure is concentrated in its scalar stiffness property. This value is a function of the specific layout. A way to compute this equivalent structural stiffness comes directly by its definition: the ratio between the generated actuation force and the derived homologue structural displacement, that is, displacement occurring along the same force direction. Because such stiffness is what the shape memory alloy actuator feels, in this article it is referred as ‘perceived stiffness’. In this article, the structural layout effect on linear shape memory alloy actuator performance is initially evaluated for a simple spring. The approach is then extended to a complex active structural system, element of an aircraft wing morphing architecture. The referred device is capable of deforming wing regions while resisting the aerodynamic and the structural loads and recovering the original shape, once the actuation stops. Structural actuator geometry is optimised as a function of the attained structural displacement (figure of merit). The work is concluded with a discussion on the achieved results, namely, rotation, vertical displacement, internal stress (strain) levels and activation temperature.

Research in noise and vibration control has partially focused on semi-active attenuation techniques such as switching shunt control (SSC) systems. Among the various methods, SSC architectures exhibit several interesting advantages such as low power absorption and intrinsic adaptive capabilities. This approach may represent an acceptable compromise between passive and active solutions. In previous work the authors implemented and validated 1D and 2D numerical models, addressed to describe continuous simple isotropic structures under tonal excitations controlled by single-element SSC system. Further efforts were then directed to extend the applicability of those models to non-isotropic structures and to multi-tone control devices. In this article, a 6-PZT network multi-tone SSC system is presented, and embedded into a balanced fiberglass laminate. The network geometry is defined according to an optimization process following modal information. The former 1-channel control circuit was extended to drive up to four independent channels. The complete system dynamics was simulated by assembling the structural matrices into a Matlab code, where both the electromechanical coupling and the control circuit behavior were taken into account. The structure was excited by broadband sweep signals in a selected range. Numerical and experimental results were compared and discussed.

The ability of modulating the dynamic response of structural elements may play a fundamental role in terms of noise and vibration propagation and reduction levels. Specifically, controlling some dynamic features, like stiffness and damping, may remarkably extend the working range of a specific component, with consequent integration and efficiency benefits. Smart Materials, combined with innovative design philosophies (i.e., ‘Self-Adaptive Structures’, ‘Self-Repairing Structures’...) gave rise to real possibilities for the implementation of non-conventional solutions. Within the noise and vibration field, a family of strategies, focused on damping (active constrained layer dampers, rheological layers) and stiffness (embedded Shape Memory Alloys, SMA, acting on the stress field) control, is developing, by giving birth to original and efficient solutions. SMA, due to their capability of transmitting large forces and deformations, and producing remarkable stiffness variations, represent good candidates for actuation problems and stiffness control solutions. The idea of using embedded SMA components to affect the structural dynamic response was already considered by several authors; among the others, Diodati and others focused their attention on the prediction of the effects due to the heat activation of SMA wires, embedded within a fiber-glass laminate. SMA induced stress originated significant FRF peaks shift, encouraging the authors to develop an optimization procedure to find out the most efficient placement and orientation of the active elements within the panel, aimed at maximizing the achievable frequency peak shift. In this article, a numerical model already introduced was examined and upgraded to suit the logic of a generic optimization process. The specific connections between the structure and the wires (sliding wires) was realized by proper constraint architecture, able to catch the best the physical nature of the mutual interaction. Then, due to the large amount of the parameters to be identified (in plane angle and location of each wire) and the non-continuous nature of some of them, a genetic optimization approach was picked up and implemented, assuming the peak shifts as the fitness function. The activated is then compared with the non-activated response, in order to estimate the attained performance.
