I used spin stabilization on the upper stage of a small two-stage rocket that I had designed to cross the Karman line. I tested the upper stage, stand-alone, three times. All three test flights lead to inflight breakups at between Mach 2.4 and Mach 2.7. I attributed the first breakup to a fin failure at Mach 2.7. I found fins amongst the various parts scattered on the Black Rock Playa. I reinforced the fin assembly substantially and repeated the test with largely the same results at Mach 2.5 but with the fin assembly only suffering minor thermal damage. I increased the fin area substantially and changed to a welded aluminum structure. I also added an IMU to the payload. This launch went unstable at about 24,000 feet and at Mach 2.4. The payload and the forward section returned to earth under parachute. The aft section continued on a ballistic course and was located, stuck about 1.5 meters in a very hard Playa. Analysis of the IMU data showed the rocket increasing in spin rate until it approached the lateral aerodynamic resonance of the rocket at that speed. The rocket was not balanced around the axis of rotation which induces a nutational torque about the logitudinal CG. This torque was easily overcome by the fins until the spin rate approached the longitudinal resonance. The longitudinal stability was heavily underdamped and the excitation of the rotational imbalance caused the angle-of-attack to exceed limits and the rocket quickly turned perpendicular to the direction of flight and broke up. Who would think that larger fins and spin stabilization would result in a more unstable rocket? I don’t understand, “it must be a rocket thing”.
I like to think, millions of years from now a couple on another watery world somewhere with an atmosphere will see a shooting star and make a wish on a small piece of New horizons

I really enjoy your videos. You break down so many things to where I can understand them. I am not a dumb person but am no rocket scientist either. I believe since you are not one either but have studied for your own curiosity you know how to break it down.
Very interesting - even if my brain did fail towards the end! We shouldn't be too surprised at spin stabilisation, though - after all bullets have been doing it ever since rifling was invented. And long may you continue to pronounce the 'h' in 'when' - so good to hear!
The Pioneer 10 and 11 probes to Jupiter and Saturn were spin-stabilized and just retained the spin. They actually used it in their imaging system--the system could only detect a single pixel at a time, but this would sweep out an arc as the spacecraft rotated, and then they could build up an image by re-aiming the scanner on successive rotations.
I remember watching the launch when I was 8. I always thought it was used as a one axis gyroscope to control the steering of the rocket. We weren't quite that sophisticated back then.
I've been following spaceflight since I got Bell X-1 and X-15 pix in my cereal, but I hadn't encountered yo-yo spin-down until now. That's why I follow this channel.

Could be a culture mix issue. In aviation distances are nautical miles, and speeds are knots. In space it's often metric units. Since those stages will come down, they're handled by aviation guys, and the payload isn't.. so each use their own preferred units for their part.
