The shape of an inflatable Sharp rotor could surely be ensured by using shapewave® technology, and perhaps at any dimensions.
LIGHTWEIGHT
shapewave® technology uses coated fabrics available airtight from the roll, for use in constructions from ultra light to heavy duty. Each of the thousands of webs inside your shapewave® inflatable is precision calculated in accordance with physics laws by our WAM software for an optimised construction.
Our ultralight proprietary tape material hardly adds to the construction weight. Weight savings of over 60% compared to traditional inflatable tech are within reach. At the lightest of light, we’re looking at construction weights south of 100gr/m² for ram-air canopies.
FREEDOM OF SHAPE
Liberate your designs from tubular, flat panel or box confinement as you tap in to the world of shapewave®! Double curvature, sharp edges*, convex or concave, our proprietary WAM software will fill your design out with the required tape density, while providing panel join lines to build the inflatable parts you’ve been dreaming of.
*Current minimum radius is R18mm. Note that thin sections of inflatables can become “soft” due to reduced hoop stress. Blame physics! However, sharper edges can be achieved by other means, please contact us for details.
I tested (see the video) of this self-rotating rotor with a high coefficient of lift (close to 3).
With this technology it could be build at good dimensions compared to my limited foam rotors, perhaps at high scale. What do you think @Rudo ?
