In the last century, traditional wings were among the best in getting aircraft into the air, but there are some other interesting designs that come and go. One of them is the Magnus effect plane, which uses the lift generated by a rotating cylinder. [James Whomsley] from [Project Air] Decided to create one as a side projectBut it was ultimately more challenging than he initially suspected. (Video, embedded below.)
The Magnus effect gained some viral fame within a few years, when [How Ridiculous] A basketball fell from the dam wall There is some backspin. [James] There is a pair of rotating cylinders at the top of the T-shaped Magnus effect plane to generate lift, which is driven by a brushless motor using a belt. The second brushless motor with a propeller is located on the central carbon fiber tube to provide forward thrust and the rudder provides yaw control. The battery is fixed at the bottom of the bathtub to maintain stability.
The first flight looks promising, but [James] Soon a series of problems related to the center of gravity, power, pitch control and drag were encountered. After the iterations of the build-collision-rebuild cycle, he finally got larger motors and rudders, shorter “wings” and higher thrust motor positions. As a result, the aircraft could still barely control, but stayed in the air for a long time. Since he never intended to turn it into a long-term project, James]claimed that it was successful, avoided more yak shaves, and continued to work on his motorboats and rocket planes.
If you are interested in building one of your own, he will put all his experimental results in a short report. For more inspiration, check out another Magnus effect aircraft that uses KFC buckets as wings.
