Açıklama

A small wind tunnel for testing aerodynamic drag on parts. Uses a 200mm PC fan (https://www.amazon.co.uk/Noctua-NF-A20-PWM-Premium-200x30mm/dp/B071SLFBNY), m4 bolts, m4 nuts, and 4 sheets of acrylic from Cut My Plastic (https://www.cutmy.co.uk/plastic/acrylic-perspex-sheets/) using the templates in the downloads. There are 2 velocity mounts, one uses straw bundles (https://www.amazon.co.uk/Cocktail-Drinking-Diameter-Cocktails-Reusable/dp/B09YRBVQ1C/ref=sr_1_8?dib=eyJ2IjoiMSJ9.EhDD5fIUQv5KfDz4BgyygpUOBVwKhqYlijOeVK-pgHF_Qdce09_Ai-3-sKeNdWadhPG4yr_EA3tigWZOzx43uQQHJMNBAbLhcKo11egAs8xp2NUWv2nKG6lzNsgl5Ezx3AYTyJZqXBb-_qI4yRnhkPCMQdd-PdorePSpAwDas80MahxeW4MrnwWpuC3hB1URsgUK2qZqskrph20CklGKFeeGVyTEE9Rg_a6RDs-5QxxQqHlF3omrIwJioxDOqQt3ifDyPAhyf5wbVcLTO-mOOq6S1kxE_2TyI2IoPxFHywA.jXcy-YPy8bS6pD0SMN6ohJXl_Zm2aknvnYL75ceJbgA&dib_tag=se&keywords=plastic+straws&qid=1725488719&sr=8-8) and the other is fully 3D printed. The fully 3D printed one will use a reel of filament (~1kg). The straw velocity mount uses much less but requires more work to cut the straws to 5cm and bundle ~600 of the cut straws together (See photos). ** I HAVEN'T TESTED THE CIRCLE INSERT, PRINT AT YOUR OWN RISK ** 14/09/2024 V1: Added a circle velocity mount, a straw velocity mount, and hex velocity mount. Added feet for wind tunnel. 09/10/2024 V1.1: Increased hole spacing for fan mount from 153mm to 154mm. 08/12/2024 V1.2 Misaligned bolt holes for acrylic on the fan mount. Fixed this issue. 13/12/2024…
