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”.

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.

@@wictimovgovonca320 The handle is heavy, it is the natural core that could spin stably forever. When the tool is spun around the lighter axis, it is unstable. It keeps spinning, but it is not a natural spin because it is along the wrong axis. By analogy if the nickel/iron magnetic flux at the core of the earth is not spinning in the same direction as the surface of the planet (as the increasing divergence of the magnetic poles from true north shows), the inner core can flip in the same way the tool did, possibly dragging the surface along with it.

@@lukasskymuh5910 The mod BDB has yoyo parts
I can't stop chuckling, every time you said it, it sounds like you are saying "Exploder One".
yo-yo despin works not only by increasing inertia tensor but also because wire is wound up around the stage, so when it gets unwound centrifugal force from weights is actually applied to the side of the stage (not center of mass). and it literally pulls the stage in the direction opposite to rotation. with only inertia tensor increase your can slow rotation (maybe by 3) but never stop it or go in reverse.

What a great episode! Thank you for sharing your knowledge,
Phantom Menace reference noted.
Watching that T-handle I finally understand how and why the earth can suddenly flip it's polarity.
I don't think I understand it any better, it just makes it easier to accept
@@wictimovgovonca320 The handle is heavy, it is the natural core that could spin stably forever. When the tool is spun around the lighter axis, it is unstable. It keeps spinning, but it is not a natural spin because it is along the wrong axis.
By analogy if the nickel/iron magnetic flux at the core of the earth is not spinning in the same direction as the surface of the planet (as the increasing divergence of the magnetic poles from true north shows), the inner core can flip in the same way the tool did, possibly dragging the surface along with it.
Love your videos Scott
great information
