When it comes to building decent aerodynamic devices, you want to focus on getting your geometry accurate, as well as making sure your parts are strong sufficient to offer with the force they’re generating. This develop from [Engineering After Hours] delivers on those fronts, including a high-downforce wing for a little RC car.
The video explains that, at best, even a decent RC cars and truck will have quite crappy aerodynamic parts from the factory, with a lift-to-drag (L/D)ratio of 2-3:1 at best. This means that, while they may produce some little amount of downforce, they’re likewise producing lots of drag at the exact same time.
The dual-element wing designed right here is much more efficient, hitting an L/D ratio in the vicinity of 17:1 – a significant improvement. even a laid-back eye can note that the style looks a great deal more like something you’d see on a full-size car, versus a few of the whackier styles seen on toys.
The wing is developed with a forged carbon fiber process utilizing 3D-printed molds, to provide the wing lots of strength. provided that it’s developed for an RC cars and truck that can do over 100 mph, making sure the wing is rigid sufficient to perform at speed is key.
[Engineering After Hours] does a excellent task of showing exactly how to prepare the molds, fill them with carbon fiber, as well as pour the resin, as well as discusses lots of useful tips on exactly how to accomplish great results with the forged carbon process.
The result is an incredibly impressive rear wing with aerodynamic performance to match its great looks. It may be more challenging than 3D printing, however the results of the work are that much tougher.
We’ve seen other aero experiments from [Engineering After Hours] before, too. video after the break.
