Title:
A Anti-ice system and a method
Document Type and Number:
Japanese Patent JP6258328
Kind Code:
B2
Abstract:
A de-icing system for a hemispherical protective housing mounted on an aircraft structure is described. The system can include a series of piezo-electric devices mounted at the boundary of the housing. The piezo-electric devices generate ultrasonic frequencies and resonance of the protective housing is induced. One of the piezo-electric devices senses the frequency generated in the protective housing and acts as part of a feedback loop to maintain structural resonance of the protective housing. The structural resonance of the protective housing prevents the build-up of ice. Additionally, higher power resonances can be generated to remove ice already built up on the protective housing. The system also enables detection of ice build-up on the protective housing by monitoring any change in the frequency required to maintain structural resonance of the protective housing.
