Objectives

The overall objective of the project is to develop a smart, energy-efficient, environmentally safe and autonomously operated de-icing procedure based on surface acoustic transducers integrated over large area substrates. This will be achieved through the surface microengineering of systems capable of exciting plate and Rayleigh waves onto a variety of materials and that may incorporate anti-icing layers and SAW sensors, allowing operation according to predefined feedback algorithms.

Specific objectives (SO):

SO1. Effective de-icing with “high frequency vibrations”. IDTs and/or planar electrodes will be incorporated as oscillators to generate either SAWs or long-wavelength AWs capable of effectively produce de-icing without inducing total melting of ice layers.

SO2. Synergistic combination of de-icing (active) and anti-icing (passive) mechanisms by a tailored fabrication of surface anti-icing components.

SO3. Understanding the atomic-scale effects of acoustic waves at the interface between solid surfaces and minus-zero liquid droplets and/or ice particles. Description of energy propagation mechanisms through the interface.

SO4. Demonstration of the applicability of acoustic wave de-icing over larger areas and comparison of its performance with thermal ice prevention and conventional ultrasounds de-icing systems.

SO5. Development of a feedback system and algorithms for autonomous and optimized de-icing operation based on surface integrated microengineered SAW sensors for ice detection and automatic control of (s)AWs excitation.

SO6. Validation and benchmarking of the technology with a proof of concept device (PCD). The accomplishment of SOs 1-5 will be demonstrated and validated with a final PCD incorporating the smart (s)AW de-icing systems onto a large area substrate.
