Bad weather beaten! Exciting sortie that was meant to be 3 minutes @ 1,500ft turning into a 25 minute 3,000ft climb followed by an "expedited" descent back to Earth to avoid the showers. So good to be back aloft again since January.

Gliding Like a Grasshopper
Many biorobots are built after flies and bees–insects that rely heavily on flapping flight. For small robots, this means carrying heavy batteries or remaining tethered in order to power their motors. Instead, researchers have turned to grasshoppers for a lesson in small-scale gliding.
Grasshoppers have two sets of wings. The forward set provide protection and camouflage, while the hindwings are used to fly. The team studied the corrugated, foldable hindwings of the American grasshopper, then 3D-printed model wing designs and attached them to gliders. They found that the corrugated wings performed well at low angles of attack, but that non-corrugated wings–which still shared the outline and camber of the insect’s wings–were more efficient gliders over a range of conditions.
The team hopes that their grasshopper-inspired gliders give insect-like biorobots more efficient flying options. (Image credit: Princeton/S. Khan/Fotobuddy; research credit: K. Lee et al.; via Physics World)

Erstmals kommt das legendäre Glasflügel Fly-In in den Norden!
Vom 25. bis 28. Juni ist über Goch-Asperden (EDLG) unweit der niederländischen Grenze mit vermehrten Libellen-Aufkommen zu rechnen.
Teilnehmer sollten sich zeitig auf der Homepage des Glasflügelvereins anmelden.

I sometimes think the nicest part of any great flying day is actually when I get back home, to the comfort of my desk, and can reflect properly on the aerial adventures had.
