New Hybrid Technology To Prevent Icing On Aircraft and Drones<\/strong><\/p>\n

The testing conducted at NASA\u2019s Icing Research Tunnel has moved the hybrid technology to a readiness level of 6 (TRL6).<\/p>\n

Invercon and NEI Corporation\u2019s newly developed de-icing system tested successfully at NASA\u2019s Icing Research Tunnel and was advanced to a Technology Readiness Level of 6. The hybrid technology is designed to prevent ice accretion on aircraft and drones.<\/p>\n

Invercon Inc. and NEI Corporation have recently announced that their newly developed de-icing system was tested successfully at the NASA Glenn Research Center\u2019s Icing Research Tunnel. The test was witnessed by engineers and scientists at the Research Center, as well as from the industry. The Invercon-NEI team met the objective of demonstrating a low power anti-ice system in conjunction with NEI\u2019s NANOMYTE\u00ae SuperAi<\/a> anti-ice coating that prevents ice accretion on the leading edge of an airfoil. The test was performed on a full-size airfoil under simulated in-flight conditions, following nearly two years of development and laboratory testing.<\/p>\n

All commercial aircraft have a built-in ice protection system, which could be either a thermal, thermo-mechanical, electro-mechanical, or pneumatic system. A common issue with de-icing devices is that they consume substantial power. Aircraft generally look to reduce power consumption, and with the advent of battery-powered aircraft, mechanisms or features that reduce power consumption are critically important. Icing presents a particular challenge for commercial and military drones, where ice can build up on the wings and propellers and result in crashes. In fact, the current practice is not to fly drones when icing conditions are predicted. Applying a passive anti-ice coating that functions synergistically with an active de-icing device is an attractive hybrid approach, which the team of NEI and Invercon has now demonstrated on full-scale prototypes.<\/p>\n

NEI\u2019s NANOMYTE\u00ae SuperAi anti-ice coating is a durable coating, suitable for permanent application. The coating leads to a lubricating surface that drastically reduces the adhesion strength of ice \u2013 by as much as 80%, compared to bare polished aluminum. The coating is usually applied by spraying, like conventional painting. NANOMYTE\u00ae SuperAi coating is available for commercial use.
\nInvercon has developed a new, retrofittable, electro-pneumatic deicing system that combines the most attractive aspects of several existing systems without their associated drawbacks. The Invercon system requires remarkably low power (\u2264 2.5 kW), is retrofittable on any airfoil, adds very little weight (~50 lbs.), and is durable enough to last the life of the aircraft once retrofitted. Importantly, the system looks, feels, and acts like the original leading edge and can provide millions of maintenance-free deicing cycles. The entire wing test section (Figure 1) was coated with NANOMYTE\u00ae SuperAi.<\/p>\n

Invercon successfully completed icing tests of the electro-pneumatic deicing system at NASA Glenn\u2019s Icing Research Tunnel (IRT) under a full range of representative icing conditions. The Invercon system was able to provide continuous deicing of the wing section leading edge over all the test conditions ranging from temperatures of -3\u00b0C to -20\u00b0C with various liquid water content. Typically, the system allows ice to accrete for about 2 minutes and then completely sheds upper and lower surface ice upon system activation.<\/p>\n

The testing at NASA\u2019s IRT, which is the longest running icing facility in the world, has moved the hybrid technology to a readiness level of 6 (i.e., TRL6), which is a scale used by NASA and Department of Defense to gauge the maturity level of a technology.<\/p>\n

Both NEI Corporation and INVERCON LLC are grateful for the financial support extended by the Small Business Innovation Research Program from the Air Force and NASA. The SBIR program funds product development efforts that reduce concepts to practice and then to prototypes, thereby reducing technology risk. The successful full-scale demonstration by the team has advanced a new technology to a state of commercial readiness.<\/p>\n

\u306b\u3064\u3044\u3066<\/strong> NEI Corporation<\/a>:
\nNEI Corporation is an application-driven company that utilizes nanotechnology to develop and produce advanced materials. The company\u2019s core competencies are in synthesizing nanoscale materials and prototyping products that incorporate the advanced materials. NEI offers an array of Advanced Protective Coatings for metal and polymer surfaces. The coatings have tailored functionalities, such as anti-corrosion, self-healing, scratch resistance, ice-phobic, and self-cleaning.<\/p>\n

\u306b\u3064\u3044\u3066 <\/strong>Invercon LLC<\/a>:
\nInvercon\u2019s mission is to develop advanced technologies that enable revolutionary leaps forward in aircraft performance and safety. For rotorcraft, these include centrifugally powered, pneumatic actuation systems that can actively trim rotors and de-ice rotor blades using almost no power or weight, resulting in significantly improved performance and safety. For fixed wing aircraft, Invercon has developed extremely low power deicing solutions using a novel electro-pneumatic actuation approach.<\/p>\n
