Abstract
A method for the anti-icing treatment of a surface of an aircraft part made of an organic matrix composites includes a texturing step in which the surface is irradiated with femtosecond laser pulses so as to render the surface superhydrophobic.
Claims17
A method for treating a surface of an aircraft part made of organic matrix composites and for assembling said aircraft part, the method comprising:
- a texturing step in which the surface is irradiated by femtosecond laser pulses so as to make the surface superhydrophobic;
- and
- assembling a piezoelectric component with said aircraft part, the piezoelectric component forming a mechanical de-icing device being configured to generate vibration to break ice accumulated on the surface of the aircraft part.
An aircraft propulsion unit comprising:
- an air inlet section comprising an air inlet lip made of organic matrix composites, the air inlet lip having a surface treated with a method comprising a texturing step in which the surface is irradiated by femtosecond laser pulses so as to make the surface superhydrophobic;
- and
- a piezoelectric component forming a mechanical de-icing device configured to generate vibration to break ice accumulated on vibrate the surface of the air inlet lip.
