When ice builds up on aircraft either through precipitation on the ground or by formation of ice during flight, it’s dangerous. Ice can add significant weight, requiring more fuel expenditure and potentially making the aircraft too heavy to fly. It also changes the aerodynamics of the aircraft’s surfaces, adding drag and reducing lift. Any of this could mean a cancelled mission, or more seriously, a mission failure. Battelle’s HeatCoat™ technology uses a high-conductivity, carbon nanotube heating coating that conforms to the existing skin of the aircraft and utilizes intelligent sensors and controls to reduce ice accumulation without compromising flight performance.
