Abstract:

Icing seriously affects the aerodynamic performance of aircraft. Therefore, ice removal with low energy consumption, high efficiency, and fast response is critical for aircraft, particularly for UAVs. Based on the characteristics of high jet strength, low energy consumption and fast response of arc discharge plasma actuators, we conducted experimental and theoretical research on ice breaking. Analysis of ice-breaking characteristics of a single exciter for different length-width ratios showed that the effective ice-breaking radius of a single exciter is about 5 cm. Meanwhile, the relationship between discharge energy and ice-breaking thickness is established. From the perspective of energy control, the ice-breaking characteristics and crack propagation law of an exciter array under the condition of fixed discharge energy are studied, showing that reasonable setting of the exciter spacing achieved a larger de-icing area than that of a single exciter with the same energy consumption. The research results can provide theoretical and practical reference for aircraft with low energy consumption and large-area ice removal.

Key words: aircraft de-icing, arc discharge plasma actuator, ice-breaking properties, law of ice crack propagation, plasma synthetic jet
