Jun 20, 2023 · Dzhanibekov noticed a peculiar behavior of a wing-nut as it spun off a bolt in the zero-gravity environment. The wing-nut maintained its orientation for a short time, then flipped 180 degrees, and continued this flipping at regular intervals.

Mar 29, 2025 · Animation of the simulated tumbling behavior of a T-handle in space demonstrating the instability of rotation about the intermediate principal axis. The animation in Figure 3 was generated using the following MATLAB code: ** Run this code first to obtain the symbolic equations of motion called by the main script.

Spinning objects have strange instabilities known as The Dzhanibekov Effect or Tennis Racket Theorem - this video offers an intuitive explanation. Part of this video was sponsored by LastPass,...

Aug 21, 2015 · But if you rotate it on an intermediate axis (watch the video below to see what he means), the rotation is unstable. The object will flip back and forth in orientation as it spins, because it's trying to spin itself on the more stable large or small axes instead.

Dec 12, 2019 · My video looks a little bit blurry but it certainly show the dzhanibekov effect, it is obvious if you observe...more. Just found a wing nut from my inventory😆 so I just film it. This is the...

Mar 7, 2024 · In 1985, Vladimir Dzhanibekov, while on the “Salyut 7” space station, unscrewed a wing nut from one of the studs inside the spacecraft so that the nut freely flew off the stud and continued...

A Flipping Bad Idea Or, how one wing nut can spoil a whole bunch of space movies. There’s a weird looking effect created by some spinning objects in micro-gravity.

Sep 1, 2020 · Supplies from Earth were locked down with wingnuts, which have three axes of rotation. As Dzhanibekov unscrewed the nut, he noticed a peculiar behavior. The wingnut spun and then flipped. You can see this same behavior below with a T-shaped object.

Flipping periods for various combinations of inertial properties of the spacecraft are presented in a systematic way. This paper discusses strategies to the increase or reduction the flipping and/or wobbling motions.

Dec 12, 2019 · In 1985, cosmonaut Vladimir Dzhanibekov commanded a mission to repair the space station Salyut-7. During the operation, he flicked a wing-nut to remove it. As it left the end of the bolt, the nut continued to spin in space, but every few seconds, it turned over through .
