Durable Icephobic Cellulose Nanopaper Composite for Aircraft Icing Mitigation, Phase I

Completed Technology Project

Project Introduction

Existing aircraft ice protection systems operate at the expense of other payload and add significant weight, power requirements, system complexity, or cost. A completely passive technology that would prevent ice accretion is highly desired, but no known technique has reached a level of effectiveness, durability and cost-efficiency to merit commercialization. Helicity Technologies proposes to integrate our proprietary icephobic liquid into a durable, easily renewable, environmentally friendly, icephobic composite that does not distort airflow and adds negligible weight. In Phase I, we will develop a cellulose nanopaper base layer for the storage and replenishment of our functional fluid to dramatically extend its useful life. Methods for increasing cellulose nanopaper strength and elasticity, and improved control of porosity will be explored. The resulting icephobic composite prototype will be tested for performance under simulated icing conditions in an icing wind tunnel. More »
