"simple challenge" AS a designer and manager in an R&D facility for a major multinational developing highly complex electronic devices let me assure you it is not "simple" unless you make it easy and by sealing it you've lost that option
It's the physics of the wind motion not the devices and how that motion affects the devices ability to operate NOT how they affect the materials.
Unless you are envisaging ultra fast surface shape modification materials capable of altering physical shape in sub second times ? THe most advanced aerospace divisions are barely scratching the surface of being able to do that much slower on the most expensive research planes wheih are much larger than a blade
