Wingrigg
Since the Americas Cup is at the doorstep, I made a model of a wingrigg and tested in the wind tunnel.
Since the Americas Cup is at the doorstep, I made a model of a wingrigg and tested in the wind tunnel.
I built a simple wing profile from plywood and paper and made a short video. In contrast to the sail profile, the wing is less sensitive against stalling. Its possible angle of approach is bigger. Good for pilots, bad for sailors. I will have a closer look on the physical effects, in order to understand what happens in detail. …
Fabio had the idea to film the air flow around the viking ship from inside the wind tunnel, with his GoPro Hero4. Thanks you for lending it to me, Fabio! I was able to play a little bit with it and followed his idea. I really like the GoPro Hero4. As “tripod” I used an …
To show the effects of different sail profiles on the air flow, I built a “sheet” of small wood bars and light fabric, which are backed with a rubber band. A profile attached to a servo controller can be pressed against the sheet to bend it more or less, thus changing the sheet’s profile. At the …
Last week, we put some car models – a model of a Dodge Viper and various Formula 1 cars – into the windtunnel to see what would happen. I created deskbreeze to be able to explain the windflow on sails, but it’s also fascinating to watch the airflows around the cars. On the Viper model, we …
Following the overwhelmingly positive feedback on the Maker Faire in Vienna we have changed the name of the project from ” Mini wind tunnel ” to ” Desk Breeze ” . After finding the name and doing all the technical stuff the website online. Last week we also made pictures and videos . Since there will be more, …
