SUMMARY

The discussion focuses on the comparison between Euler Angles and Tait-Bryan Angles in the context of body rotations. Euler Angles utilize the same axis for the first and third rotations, while Tait-Bryan Angles represent distinct rotations about three axes: Yaw, Pitch, and Roll. A specific case of steady precession in Euler Angles is identified, where the precession rate is constant, nutation rate is zero, and spin rate is constant. The analogous case in Tait-Bryan Angles is termed "Steady Turn," characterized by a constant yaw rate, zero pitch rate, and constant roll rate, commonly referenced in aviation and aerospace engineering.

TL;DR
what is the analogue of steady precession when using the Tait -Bryan angles
Good Morning

When one studies body rotations, there are two general approaches one uses: Euler Angles vs. Tait-Bryan Angles.

The significant difference is that:
  • Tait–Bryan angles represent rotations about three distinct axes (e.g. x-y-z, or x-y′-z″): Yaw, Pitch, Roll
  • Euler angles use the same axis for both the first and third elemental rotations (e.g., z-x-z, or z-x′-z″): Precession, Nutation, Spin

With Euler angles, there is a special case of STEADY PRECESSION: precession rate is constant, nutation rate is 0, spin rate is constant.

Is there a NAME for the analogous case, when modeling with Tait? Yaw rate is constant, pitch rate is 0, roll rate is constant?

Yes, there is a name for the analogous case in Tait-Bryan angles. It's called "Steady Turn," also known as "Constant Turn" or "Banked Turn." In this case, the yaw rate is constant, the pitch rate is zero, and the roll rate is constant. The term "banked turn" refers to the fact that the vehicle or object is banked or tilted to one side, like an airplane during a turn. This term is commonly used in aviation and aerospace engineering.
 
In sci-fi when an author is talking about space travellers or describing the movement of galaxies they will say something like “movement in space only means anything in relation to another object”. Examples of this would be, a space ship moving away from earth at 100 km/s, or 2 galaxies moving towards each other at one light year per century. I think it would make it easier to describe movement in space if we had three axis that we all agree on and we used 0 km/s relative to the speed of...
