“…Shape memory alloys are used in this type of system because these materials can undergo a very large dimensional change induced by relatively small temperature variations. Considering this possible effect, the shape-changing properties of these materials are used in ice protection systems to promote ice removal [51][52][53].…”

Ice accretion is a common issue on aircraft flying in cold climate conditions. The ice accumulation on aircraft surfaces disturbs the adjacent airflow field, increases the drag, and significantly reduces the aircraft’s aerodynamic performance. It also increases the weight of the aircraft and causes the failure of critical components in some situations, leading to premature aerodynamic stall and loss of control and lift. With this in mind, several authors have begun to study the thermal effects of plasma actuators for icing control and mitigation, considering both aeronautical and wind energy applications. Although this is a recent topic, several studies have already been performed, and it is clear this topic has attracted the attention of several research groups. Considering the importance and potential of using dielectric barrier discharge (DBD) plasma actuators for ice mitigation, we aim to present in this paper the first review on this topic, summarizing all the information reported in the literature about three major subtopics: thermal effects induced by DBD plasma actuators, plasma actuators’ ability in deicing and ice formation prevention, and ice detection capability of DBD plasma actuators. An overview of the characteristics of these devices is performed and conclusions are drawn regarding recent developments in the application of plasma actuators for icing mitigation purposes.

Protection systems against ice conventionally use thermal, pneumatic or electro-thermal solutions. However, they are characterized by high energy consumption. This article focuses on low-consumption electromechanical deicing solutions based on piezoelectric transducers. After a review of the state of the art to identify the main features of electromechanical de-icing devices, piezoelectric transducer-based architectures are studied. Analytical models validated by numerical simulations allow trend studies to be performed which highlight the resonance modes and the ultrasonic frequency ranges that lead to low-consumption, compact ultrasonic deicing devices. Finally, de-icing systems widely studied with bonded ceramics and de-icing systems less usual with Langevin pre-stressed piezoelectric transducers are compared and a Langevin piezoelectric transducer-based device leading to an interesting compromise is tested.

“…The activation of the SMA sheet allows the elastic surface of the wing's leading edge to contract and expand, causing shearing and peeling of the ice layer. Myose et al [4] developed SMA composites for de-icing. For this purpose, different semi-circular functional samples manufactured from SMA embedded in fiberglass epoxy composite were tested without aerodynamic loading.…”

The removal of ice accumulation on aerodynamic surfaces is a common challenge not only in aviation but also for stationary installations on the ground such as wind turbines. The aim of this paper is to investigate a novel concept for a thermo-mechanical de-icing system based on shape memory alloys. To understand the functional principle in detail, a functional sample is designed, fabricated and experimentally investigated. With a systematic design approach using a morphological box, an optimal configuration is sought and evaluated that harmonizes all relevant functions in the sense of maximum functional conformity. One selected concept forms the basis for the simulation model, which is used to investigate the influence of different parameters on the thermo-mechanical behavior of the functional sample. The results of the parameter study are used to produce a functional sample for investigating the de-icing ability. The experiments on the functional sample serve to validate and improve the simulation model. The comparison of the measurement data with the model prediction shows a good correlation between measurement and prediction with reasonable deviations. The findings on the test methodology, the manufacturing technology and the system behavior allow the further development of the de-icing concept in subsequent steps.
