Abstract

This paper proposes a method of combining low-frequency resonance signals and ultrasonic signals through envelope modulation to form an excitation signal for de-icing. Modulated signals are applied to a single type of actuator for de-icing, aiming to simplify the equipment required for de-icing and reduce power consumption. The envelope modulation signal is generated by combining low-frequency signals with ultrasonic signals using amplitude modulation, the Hamming window function, and the Hanning window function, respectively. The de-icing excitation effects of the modulation signals generated by different modulation methods at various initial phases on the ice-covered leading edge of the blade are calculated through numerical simulations. Simulations show that the modulation method and initial phase have a significant impact on the de-icing excitation effect. Experiments are conducted to explore the de-icing effectiveness and power consumption under different envelope modulation signal excitations. The results indicate that the envelope modulation signal de-icing method can simplify equipment and reduce power consumption, showing promising development and application prospects.

期刊介绍： Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense. Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems. Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
