Inflatable sails

While it seems difficult to find inflatable blades, especially for wind turbines, inflatable sails are beginning to emerge.

The project mentioned just below seems interesting for several reasons, notably the apparent possibility of achieving faithful blade profiles with inflatable structures. Other projects or achievements have been discussed.

This could be a possibility for bladed AWES that would be lighter while maintaining good efficiency.

In this field, everything remains to be proven.

About an inflatable drone (in French language):

The website in English language:

We are a company specializing in the design and manufacturing of very long range drones. Our drones are innovative hybrids, combining the advantages of a flying wing and an airship. Our goal is to create a drone that can fly for hours or even days without requiring refueling.

Hybrid Design:
Combining the best of winged
and dirigible technology, its
flexible wing envelope can be
filled with various gases, tailored
to specific mission profiles.

Some AWE possibilities?

The inflated wing shape resembles the WoopyFly hang glider

WoopyFly wing has small blowers that allow it to maintain its inflated shape.
