Wingrigg
Since the Americas Cup is at the doorstep, I made a model of a wingrigg and tested in the wind tunnel.
Physics in School
A physics classroom, a wind tunnel and dry ice: That’s a nice mixture for the end of term. Gerhard accepted the invitation of a teacher of a grammar school (BRG/BORG) in St. Pölten/ Lower Austria, to present Deskbreeze during the physics class. After three hours with “dynamic uplift” and the hydrodynamic laws of Daniel Bernoulli with aroud 80 …
Wing in the windtunnel
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. …
Deskbreeze goes GoPro
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 …
Sail profiles and air flows
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 …
Cars in the wind tunnel
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 …
Our Website is online
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, …
