Why was the Bede HB-1 called Super Demoiselle?

The Bede HB-1 Super Demoiselle was an ultralight designed by Jim Bede in 1966 and marketed for amateur construction. It was named in honor of the Demoiselle —French for "dragonfly"— Santos-Dumont's pioneering aircraft, which had a similar overall configuration.

The Super Demoiselle carried the pilot in an open structure suspended by struts beneath a parasol wing. Its V-tail was mounted on a boom extending from the wing, and a single tractor-propeller piston engine was fitted to the wing's leading edge. It was designed for engines of between 65 and 100 hp (48 to 75 kW).

The wing was formed from 15 identical fiberglass sections mounted on an aluminum spar, and it was the first Bede design to introduce that construction method among home builders. The entire airframe consisted of only 85 components, and Bede claimed it could be built in a couple of months for $700.

Bede also designed the BD-2, conceived to attempt a round-the-world flight without in-flight refueling. That aircraft set a world distance record for a closed circuit for piston-engined aircraft, on a flight that had to be stopped due to a total electrical failure.
