Abstract:
Deicing using piezoelectric actuators is considered as a potential solution to the development of low-energy ice protection systems for rotorcraft. This type of system activates resonant frequencies of a structure using piezoelectric actuators to generate sufficient stress to break the bond between the ice and the substrate. First, a numerical method was validated to assist the design of such systems. Numerical simulations were performed for the case of a flat plate and validated experimentally. The model was then used to study important design parameters such as actuator positioning and activ

Abstract:
The peak current and vibration peak acceleration are two important parameters in the electroimpulse deicing system. Available data on two parameters are sparse. An experimental setup to measure the peak current and vibration peak acceleration in the electroimpulse deicing system is presented. The measurement is performed in the icing wind tunnel. Rogowski coil’s principle on pulsed current measurement is applied in the electroimpulse deicing discharge current circuit. It is found that calculated results agree with the measured trend. A piezoelectric vibration acceleration sensor is adopted to

Abstract:
Abstract Piezoelectric actuators are widely used in several applications and are becoming increasingly attractive in aircraft and industrial 
contexts, mainly when efficiency and economical energy conversion are required. One of these applications is the Avionic 
Piezoelectric Deicing System. Piezoelectric actuators are considered as a potential solution for developing a low-energy ice 
protection system for aircraft. This type of system applies vibration to the structure by activating its own resonant frequencies 
to generate sufficient stress to break the ice

Abstract:
AbstractRecent research shows a growing interest in low‐power avionic deicing systems, in particular, those based on piezoelectric actuators for their energy efficiency. The system generates micrometric vibrations in the structure to delaminate and break the ice with a low power requirement. However, designing the power supply and its control for driving piezoelectric actuators is challenging due to their distinctive capacitive behavior at most frequencies, especially in deicing applications requiring high operational frequency. This contribution addresses the two cross‐dependent parts of the

Abstract:
Les contraintes environnementales, ainsi que leur impact sur l'opinion publique, ont conduit les équipementiers aéronautiques à accélérer la transition énergétique en aéronautique à travers l'avion plus électrique (More Electric Aircraft - MEA). Nous assistons donc à une augmentation progressive de la place de l'énergie électrique dans les applications embarquées. Ceci se traduit par une tendance à remplacer les systèmes non propulsifs (hydrauliques et pneumatiques) par des chaînes de conversion électromécanique. Ces sous-systèmes sont en effet souvent plus performants, dynamiques et précis av

<div class="section abstract"><div class="htmlview paragraph">This paper proposes an extension to curved surfaces of a design method of piezoelectric ice protection systems established for planar surfaces. The method is based on a finite element analysis which enables the fast computation of the resonant modes of interest to de-ice surfaces as leading edges. The performance of the modes of interest is assessed according to their deicing capacity estimated from the electro-mechanical coupling between the electric charge of the piezoelectric actuators and the strain energy in the str
