Abstract
A rain-resistant, drainless, heated air data probe assembly may comprise a probe having a central channel, one or more peripheral channels, and a heating element. In addition, inner surfaces of the channels may include hydrophilic surfaces, and the outer surface of the probe may include hydrophobic surfaces. The hydrophobic outer surface may reduce water ingress into the channels of the probe, and the hydrophilic inner surfaces may cause dispersion of water that has entered the channels. The heating element may further cause evaporation or running off of water on the outer surface, and may cause evaporation of dispersed water within the channels, which may further eliminate the need for a drain at a terminal end of the probe assembly.
